Best Google Ads Agencies in the UK (2026 Ranking)

Short version: The "best" Google Ads agency in the UK is not one name, it is the one that fits your category, budget, and stage. This is a working list of eight strong UK Google Ads and PPC agencies for 2026, with the facts you would otherwise spend an afternoon digging out: when each was founded, where it is based, how big it is, what it says about Google Partner status and pricing, which clients it names publicly, and one published case study per agency with a link so you can read it in full. One disclosure before we start: this is the site of a Google Ads specialist practice, so we have an interest in this topic. We have kept ourselves out of the ranking itself and put our own pitch further down the page, clearly labelled, so you can weigh it separately.

A note on how to read any "best agencies" list, including this one. No agency is best at everything. A large London performance shop that runs eight-figure media budgets beautifully may be the wrong home for a lean Shopify store, and a two-person boutique that lives inside Merchant Center may be the wrong home for a FTSE brand. So instead of pretending there is one winner, we have described what each agency is actually strong at, with an honest read on who it suits and who should look elsewhere.

How we judged "best"

Before the list, the criteria. A genuinely good Google Ads agency in the UK should show most of these, whatever its size:

• Accountable to a business metric (ROAS, profit on ad spend, revenue), not to clicks or "optimisations made."
• Senior people on the account, not a junior running templates while the founder sells.
• Real e-commerce depth: active management of the product feed, Shopping, and Performance Max, not "set and forget."
• You own your account and data, with a clean exit and no heavy lock-in.
• Transparent reporting you can actually read.

Where the facts on this page come from

Every fact in the agency entries comes from a public source we checked in November 2026: the agency's own website (about, services, case study and contact pages), its Clutch profile, Companies House, or trade press such as Prolific North. Where two sources disagree, we say so. Where we could not find something, such as a headcount or a price, we left it out rather than guess. The case study numbers are each agency's own published results. We have not worked inside their client accounts and cannot audit those numbers, so we report them as claims and link to the source, and the section after the list explains how to read them.

The best Google Ads agencies in the UK for 2026

The order runs roughly from the largest organisations to the most focused boutiques. It is not a score. A brand spending 5,000 GBP a month should read the bottom half first, and a multi-market enterprise should start at the top.

1. Brainlabs (London)

Brainlabs was founded in 2012 by Dan Gilbert, who left Google to build the agency he wished existed. It started as a paid search shop built around engineers, statisticians and data scientists, and has grown into a global, full-service media agency. Its UK office is the White Collar Factory on Old Street in London.

• Founded: 2012, by Dan Gilbert (still founder and CEO)
• HQ: London, with hubs across five continents, including New York, Toronto, Sydney, Singapore and Bengaluru
• Team size: over 1,000 staff, working with more than 250 brands
• Specialties: paid search, Search Ads 360 and enterprise bidding, Performance Max, paid social, programmatic and CTV, retail media, data and measurement
• Partner status: describes itself as "premier partners of all major advertising platforms," and was named International Growth winner in Google's 2026 Ads Impact Awards
• Pricing: not published

Notable clients: Crocs, Howdens, Mars Petcare and Anglian Home Improvements, all named in case studies on the Brainlabs website.

Case study: For Crocs in EMEA, Brainlabs consolidated the platform structures, introduced automated bidding inside its own campaign architecture and standardised how the work was run across markets. It reports that the first search project delivered a 589 percent revenue uplift and a 29 percent ROAS increase year on year, and that a later search restructure before Black Friday delivered a 253 percent revenue uplift with stable ROAS (source). For a UK example, Brainlabs moved Anglian Home Improvements to an enterprise bidding structure in Search Ads 360 and reports 45 percent higher ROAS and 95 percent growth in conversion value (source).

Best for: large advertisers running several markets who want media science, engineering and Search Ads 360 depth under one roof. Less suited for: small and mid-size stores. The model is built for scale, and a lean Shopify account would be a very small part of a very large agency.

2. Impression (Nottingham, London, Manchester)

Impression was set up in Nottingham in November 2012 by Aaron Dicks and Tom Craig, and grew from two people to 15 in about three years. Today it describes itself as "120+ strong," with offices in Nottingham, London, Manchester and New York, and runs paid search alongside SEO, digital PR, paid social and analytics.

• Founded: November 2012, by Aaron Dicks and Tom Craig
• HQ: Nottingham (Fothergill House, King Street), with offices in London, Manchester and New York
• Team size: 120+ people
• Specialties: PPC and paid search, Google Shopping, paid social, programmatic, SEO, digital PR, measurement and CRO
• Partner status: its Google Partner page states it is "accredited as a Google Premier Partner"
• Pricing: not published on its site. Clutch lists a minimum project size of 5,000 US dollars and an hourly rate of 150 to 199 US dollars

Notable clients: Wizz Air, Specsavers, Cancer Research UK, Clarins, Topps Tiles and Vaillant, all shown as client logos on its homepage.

Case study: A UK online electrical retailer wanted to be seen as a premium retailer. Impression tiered every brand as premium or non-premium, split Performance Max into separate premium and non-premium campaigns with their own budgets and targets, and built SKU-level search ads in Search Ads 360 that matched exact model-number searches using live price and stock data. Products that had not sold in a set period moved into a separate "zombie" campaign through a supplementary feed, with a Google Ads script returning each item once it sold. Impression reports a 21 percent year-on-year rise in premium brand conversions, including 145 percent for Haier and 94 percent for Samsung, plus more than 7,100 conversions from the zombie campaign between November 2024 and May 2025 (source).

Best for: mid-market and enterprise brands that want paid search planned together with SEO, PR and analytics by one large team. Less suited for: smaller stores below its typical project size, or buyers who only want a paid search specialist and nothing else.

3. Circus PPC (Leeds)

Circus is a rarity worth noting: an agency that does paid media and nothing else. It was founded in 2009, is led by managing director Rick Tobin, and since 2022 has worked from Tailors Corner in Leeds city centre, having outgrown its earlier base at Thorpe Park. Its site says it has managed more than 300 clients.

• Founded: 2009
• HQ: Leeds
• Team size: not stated as a total. Its about page profiles 20 team members
• Specialties: Google Ads, Microsoft Ads, Meta, TikTok, LinkedIn and Amazon, with a strong retail and e-commerce lean
• Partner status: its about page displays a Google Premier Partner badge
• Pricing model: management fees are set individually based on monthly spend. Contracts start at six months, with a strategy review after three, then become flexible with 90 days' notice

Notable clients: Miele, Sofas & Stuff, Lavazza, Booths, Kiddies Kingdom and Jo Alexander, from the client logos and case studies on its site.

Case study: Jo Alexander is a seasonal garden furniture business whose Google campaigns had been off between June 2025 and February 2026. Circus took over in February 2026, worked with Sculpt Digital to restore revenue tracking so bidding could optimise for revenue, replaced a fragmented structure with fewer high-intent campaigns, phased out old broad match modified keywords, made sure none of the top 20 best sellers were disapproved in the feed, refreshed Performance Max assets and used Merchant Center promotions for the spring sale. For February and March 2026 against the prior period, Circus reports revenue up 287 percent, conversions up 170 percent and ROI up 33 percent, on spend that rose 191 percent (source).

Best for: retail and e-commerce brands that want a paid-media-only team with northern pricing. Less suited for: businesses that want SEO or PR from the same agency, or that do not want a six-month initial term.

4. PPC Geeks (Liverpool, Cheshire and London)

PPC Geeks is another dedicated paid media specialist, with its registered office in Liverpool and offices in Knutsford in Cheshire, on the King's Road in London and in Kendal in the Lake District. It starts most relationships with a free audit, which makes it easy to evaluate before you commit.

• Founded: 2017 according to Clutch. PPC Geeks Ltd was incorporated at Companies House on 8 August 2018
• HQ: Liverpool, with offices in Knutsford, London and Kendal
• Team size: 10 to 49 people according to Clutch, partly working remotely around the UK
• Specialties: Google Ads, Google Shopping and Comparison Shopping Services, Shopify ad management, lead generation PPC, Microsoft Ads, Meta, LinkedIn, TikTok and Amazon
• Partner status: its site states it is a "Google Ads Premier Partner"
• Pricing: management fees are not published. Clutch lists a minimum project size of 5,000 US dollars and 50 to 99 US dollars an hour. Free audits are offered, though the site notes not everyone who asks will receive one

Notable clients: The Prince's Trust, Whisky Online, Books2Door, The IT Bay, Just Go and Sky Park Secure, all named on its homepage.

Case study: The IT Bay is a technology retailer near Manchester that has traded for more than 25 years and stocks brands such as Dell, HP and Lenovo. PPC Geeks lined the Google Ads account up with the launch of a new website, tightened the Search and Shopping campaigns, tested product title changes, pushed high-margin products with strong click-through rates, experimented with broad match and moved some Shopping campaigns into Performance Max. Over six months it reports a 65 percent rise in revenue, 52 percent higher ROAS, 82 percent more conversions and a 76 percent lower cost per acquisition (source).

Best for: small and mid-size online stores and lead generation businesses that want paid media to be the agency's whole job. Less suited for: brands that want SEO, content and PR planned together, or large enterprises that need global media buying.

5. Koozai (Hampshire)

Koozai was founded in Southampton in 2006 and is one of the longer-running digital agencies on this list. Its head office is now at Lee-on-the-Solent in Hampshire, with offices on Old Street in London and in Preston. Managing director Sophie Roberts joined in 2016 and later led a management buyout, so the agency is owner-run.

• Founded: 2006, in Southampton
• HQ: Lee-on-the-Solent, Hampshire, with offices in London and Preston
• Team size: not stated. It reports 90 percent staff retention over the past year and an average tenure of seven years
• Specialties: Google Ads (Search, Performance Max, Demand Gen), Google Shopping, Microsoft Ads, Amazon Ads and remarketing, alongside SEO, digital PR, content and paid social
• Partner status: displays a Google Partner 2026 badge, with Search, Shopping, Video and Display certifications
• Pricing model: monthly management fees based on account size, number of platforms and complexity, charged separately from media spend, with a tailored proposal

Notable clients: TUI, Stannah, Trulawn, the V&A, Papa John's, Buyagift and Red Funnel, named on its paid search page.

Case study: WinesWithStories is an online shop selling artisan wines from around the world. Koozai built a Google Ads plan around Christmas wine buyers, set up dedicated Christmas campaigns alongside Smart Shopping, and managed bids and budgets through the peak. It reports revenue up 312 percent, transactions up 515 percent and ROAS up 178 percent over the peak Christmas period (source). The page does not give a year, and Smart Shopping has since been replaced by Performance Max, so read it as an older example of seasonal planning rather than a current playbook.

Best for: established brands, especially in travel, leisure and lead generation, that want a long-standing full-service partner with PPC as one strong discipline. Less suited for: brands that want a narrow, paid-search-only boutique.

6. The SEO Works (Sheffield)

Despite the name, The SEO Works runs a substantial Google Ads and paid social practice next to its organic work. It was founded in Sheffield on 12 March 2009 by Neil Palmer, is led by CEO Ben Foster, and moved to employee ownership through an Employee Ownership Trust when the founding directors handed over the business.

• Founded: 2009, by Neil Palmer
• HQ: Sheffield, with offices in Leeds, London, Manchester, Birmingham and Philadelphia
• Team size: 80+ specialists, according to its own site
• Specialties: Google Ads, Microsoft Ads, Shopping, Display and paid social, alongside SEO and content
• Partner status: describes itself as a Google Premier Partner
• Pricing: not published on its site. Clutch lists a minimum project size of 1,000 US dollars and 100 to 149 US dollars an hour

Notable clients: Decathlon, Tata Steel, the University of Birmingham, the NHS, Denby and Ordnance Survey, named on its site.

Case study: An office furniture and supplies company in Ireland already led its market for consumer sales and wanted to grow business sales. Its account ran every product in one campaign. The SEO Works split it into groups by product category and model, focused bidding on business keywords such as "office supplies for businesses" while excluding consumer terms, bid on top-of-funnel searches to build awareness, and added dynamic remarketing to stay in front of buyers through a purchase cycle of up to two weeks. It reports 940,000 GBP in monthly direct sales, 590,000 GBP in monthly assisted sales and more than 4,500 conversions a month (source). The page does not state the start date or comparison period.

Best for: businesses, particularly in the North, education, healthcare and B2B, that want paid and organic search run together by one accountable team. Less suited for: brands that want an agency doing paid media and nothing else.

7. ClickSlice (London)

ClickSlice is a Shoreditch-based agency founded by Joshua George, with a clear e-commerce lean. It is SEO-led, and most of its published case studies are organic, but it also runs Google Ads, Google Shopping and e-commerce PPC. It sits in the boutique tier and describes itself as "small enough to care, big enough to deliver."

• Founded: 2016, according to its about page (Clutch cites a Companies House formation date of July 2017)
• HQ: Shoreditch Stables, Kingsland Road, London, with team members across the UK and Europe
• Team size: its about page profiles 14 people. Clutch lists 10 to 49
• Specialties: e-commerce and Shopify SEO, AI search visibility, Google Ads, Google Shopping and e-commerce PPC
• Pricing model: fees are not published. The site says it never ties clients into contracts, and Clutch lists a minimum project size of 5,000 US dollars

Notable clients: Udemy, Queensberry, Humax, Plumbworld, Honeypot Furniture and Holy Clothing, named on its homepage.

Case study: Trinity Power rents commercial and industrial generators. ClickSlice took over an established Google Ads account, researched the technical equipment specs to target or exclude, tagged keywords by intent and bid on those tags, rebuilt ad groups by equipment type and by rental versus research intent, added keyword-level bids and location adjustments, and kept testing ads across thousands of ad groups. It reports the conversion rate rising from 3.76 percent to 10.21 percent, a 172 percent increase, with lead volume rising at the same time and the gains holding over consecutive years (source).

Best for: growing e-commerce brands in or around London that want SEO and Google Ads together, with direct access to a small team. Less suited for: brands that want a paid-media-first specialist with a long record of published Shopping and Performance Max results.

8. eComOne (Lincoln)

eComOne is an e-commerce performance agency in Lincoln, founded in 2018 to support "seven-figure plus eCommerce businesses." Its roots go back to SEO Traffic Lab, which Richard Hill set up in 2010. It works with stores on Shopify, Magento and custom builds across PPC, SEO and email, and in October 2026 it won Best PPC Agency and Best Integrated Agency at the UK Agency Awards.

• Founded: 2018 (predecessor agency 2010)
• HQ: Lincoln (Thomas Parker House, Silver Street), its base since 2019
• Team size: 10 to 49 people according to Clutch
• Specialties: Google Search and Shopping, Microsoft Ads, Meta, feed management, SEO, email and CRO for online retailers
• Credentials: Shopify Plus partner, Microsoft Elite Partner badge, certified B Corp since 2026, and Best eCommerce Team at the 2024 eCommerce Awards
• Pricing: not published. Its FAQ says budgets depend on margins, competition and growth targets

Notable clients: Rimmer Bros, Locks Direct, Safelincs, BushWear, Splash About and VetUK, from the case studies on its site.

Case study: VetUK sells pet medicines, food and supplements online and turns over more than 10 million GBP a year. In 2024 its paid search brought in a little over 1.5 million GBP, mostly from branded searches. eComOne moved conversion tracking to data-driven Google Ads conversions, built campaigns around best-selling products with seasonal changes, reduced the reliance on brand terms, and replaced an auto-crawled Shopping feed that had price and stock mismatches with a bespoke one. It reports that paid revenue more than doubled in 2025, with over 3 million GBP generated by Google Ads (source). The page quotes two different ROAS figures, so we have left ROAS out.

Best for: established online retailers, especially on Shopify, that want a specialist e-commerce partner without a London postcode on the invoice. Less suited for: early-stage stores, since the agency positions itself for seven-figure businesses.

The UK Google Ads agencies compared side by side

How to read agency case studies

Every case study above is published by the agency itself, which is normal and useful, but it is marketing. Before you let a headline number decide anything, read the page behind it with three questions in mind.

• What was the starting point? Turning a paused or broken account back on produces big percentages quickly. Improving a well-run account by 15 percent is often the harder job.
• What happened to spend? Revenue and conversions almost always rise when budget rises. ROAS, cost per acquisition or profit tell you more about the quality of the management.
• Is the work still current? Campaign types change. A case study built on Smart Shopping or broad match modified keywords shows how the agency thinks, but the exact tactics no longer exist in that form.

The best use of a case study is as the start of a conversation. Ask the agency to walk you through it on a call: what was broken, what they changed first, and what they would do differently now.

What Google Ads management costs in the UK

UK pricing clusters into a few recognisable patterns, and knowing them makes every proposal easier to judge:

• Entry-level retainers sit around 500 to 750 GBP per month. At this price you are usually buying a junior's time across many accounts, with a tightly limited scope.
• Typical specialist and mid-market retainers run from roughly 1,500 to 5,000 GBP per month, with most established agencies quoting somewhere in the 2,000 to 3,000 GBP range for full management of a serious account.
• Percentage-of-spend models commonly land between 5 and 15 percent of monthly ad spend, usually with a minimum fee of 1,000 to 2,000 GBP.
• London carries a premium. Equivalent service from a London agency often costs a third or more above the same work from an agency in the North, Wales, or Northern Ireland.

What the agencies on this list publish about pricing

Very little, which is normal. None of the eight publishes a monthly management fee. Circus says its fees are set individually around your monthly spend and that contracts start at six months with 90 days' notice after that. Koozai says its fees depend on account size, platforms and complexity and are charged separately from media spend. ClickSlice says it does not tie clients into contracts. The Clutch profiles give rough minimum project sizes, from 1,000 US dollars for The SEO Works to 5,000 US dollars for Impression, PPC Geeks and ClickSlice, but those are directory figures, not quotes. The only way to compare properly is to ask each shortlisted agency for a written proposal that names the fee, the minimum term, the notice period and who will run the account.

None of these numbers are wrong in themselves. The question is what the fee buys: how many accounts your manager carries, how senior they are, and whether feed and Shopping work is included or billed as an extra. A 3,000 GBP retainer with a senior specialist on the account is often cheaper, in real terms, than a 1,200 GBP retainer where nobody experienced ever opens it.

A different option: a remote senior specialist

Full disclosure, again: this section is about us, Improtics, and you should weigh it with that in mind.

There is a route the lists above never mention, because list articles are written by agencies about agencies: hiring a senior remote specialist directly. Improtics is a boutique Google Ads practice based in India, led by a specialist with over five years in the platform, 50+ accounts worked on, and more than $30M in managed spend, focused almost entirely on e-commerce. We already work with UK e-commerce brands, including UK stores whose accounts we have documented publicly, such as an e-bike store scaled from a brand new account and a portable power brand launched on a tight timeline.

The practical appeal is simple: you get the seniority of the person a good UK agency would put on its largest accounts, working directly in yours, at pricing well below typical UK retainers, because the cost base is different, not the skill. Time zones help rather than hurt: an India-based specialist has worked through most of the account's overnight data before a UK morning starts. We have written more about why this model has quietly become normal in why UK and US agencies outsource Google Ads work to India.

Who this fits: e-commerce and D2C brands spending roughly 3,000 to 100,000 GBP per month who want senior, hands-on management of Shopping, Performance Max, and search, and who are comfortable with a remote working relationship over calls and async updates. Who it does not fit: brands that need in-person meetings, a large multi-channel team covering social, creative, and brand, or a partner to run TV-scale media. If you are in the second group, the agencies above are honestly the better call.

If you are in the first group, the useful next step is a look at the account itself: book a free 30-minute audit call, or read how we work with e-commerce brands. If you are in the second, take the list above seriously.

Enterprise vs boutique: which Google Ads agency in the UK fits you?

The honest split most of this list falls into:

• Large performance shops (Brainlabs, Impression): deep bench, strong process, engineering and analytics resources, built for large budgets and complex organisations. You get reliability and scale, sometimes at the cost of senior attention per account.
• Established specialists (Circus, PPC Geeks, Koozai, The SEO Works): experienced teams, regional value, and in the case of the paid-media-only shops, real depth in the craft. The middle of the market for a reason.
• Boutiques and independents (ClickSlice, eComOne, and remote specialists like us): senior people closer to your account, more flexibility, usually the best ratio of expertise to cost for D2C and growing e-commerce brands. The trade-off is bandwidth and breadth.

For most e-commerce brands reading this, the specialist and boutique tiers are the right answer. For large enterprises with seven-figure budgets and integrated needs, the big shops earn their fee.

What to do with this list

Do not pick from a list, including this one, on name alone. A shortlist process that works:

1. Shortlist two or three that match your size. Use the comparison table: if your monthly ad spend is a few thousand pounds, start with the specialists and boutiques, and if you run several markets, start with the large shops.
2. Read one case study from each, properly. Look for a business like yours, then check the baseline, the time window and what happened to spend.
3. Ask who runs your account day to day. Get a name, their experience, and how many other accounts they manage.
4. Ask how they handle the product feed. For e-commerce, an agency that treats the feed as someone else's job is leaving your biggest lever untouched.
5. Get the terms in writing. Fee, minimum term, notice period, and confirmation that you own the Google Ads and Merchant Center accounts and keep all data if you leave.

The right partner for your store is almost never the cheapest, and rarely the biggest, it is the one genuinely accountable to your numbers. If you would like a straight, no-obligation read on how your current account is being managed, and where a senior remote specialist would change things, book a free call and we will show you exactly where it stands. If you sell into more than one market, our guide to what a strong e-commerce Google Ads agency looks like applies everywhere, and we keep rankings for the USA and India too.

Frequently asked questions about Google Ads agencies in the UK

How much does a Google Ads agency cost in the UK?

Most UK agencies charge either a fixed monthly retainer, typically 1,500 to 5,000 GBP for full management, or a percentage of ad spend, usually 5 to 15 percent with a minimum fee. Entry-level packages around 500 to 750 GBP exist but generally buy limited, junior-led service. London agencies tend to price a third or more above comparable regional agencies for equivalent work. None of the eight agencies on this list publishes a monthly fee, so expect to ask for a proposal.

Which UK Google Ads agencies are Google Premier Partners?

On this list, Impression and PPC Geeks state Premier Partner status on their websites, Circus displays a Premier Partner badge on its about page, The SEO Works describes itself as one, and Brainlabs says it is a premier partner of all major ad platforms. Koozai shows a Google Partner 2026 badge. Status is reviewed by Google every year, so check the agency's current badge, which links to Google's own Partners listing, before you rely on it.

Should I hire a Google Ads agency or a freelancer in the UK?

A senior freelancer or boutique specialist gives you experienced hands directly on the account and usually costs less than an agency retainer. An agency gives you bench depth, continuity if someone leaves, and more channels under one roof. The deciding question is not the label, it is whether the person making decisions in your account has real experience with your kind of business, especially Shopping and Performance Max for e-commerce. We compare the options properly in our guide to consultant vs agency vs freelancer.

How do I know if a UK agency is actually good at Google Ads?

Look past the awards wall. Ask them to walk through a real account they improved, including what was broken and what they changed. Check whether they report on revenue and profit rather than clicks, whether they can explain last month's changes in plain English, and how many accounts each manager carries. An agency that answers those four questions directly is usually a safe pair of hands regardless of its size.

Can I trust the results in agency case studies?

Treat them as honest marketing rather than audited results. The numbers are usually real, but they are chosen to look good and often leave out the baseline, the time window or what happened to spend. Use them to judge how an agency thinks about a problem, then ask them to walk you through the account behind the headline on a call.

What should I ask before signing with a Google Ads agency?

Ask who owns the Google Ads and Merchant Center accounts, whether you keep all historical data if you leave, what the minimum term and notice period are, and exactly who will be working in your account each week. For e-commerce, add one more: how they manage the product feed, because an agency that treats the feed as someone else's job is leaving your biggest lever untouched.

Does my Google Ads agency need to be based in the UK?

No. Google Ads is the same platform everywhere, your account manager works in it remotely whether they sit in Leeds or elsewhere, and UK market knowledge is learned from your data, not from a postcode. What matters is seniority, e-commerce depth, communication in your hours, and clean account ownership. Plenty of UK brands now pair with senior remote specialists precisely because it buys more experience per pound; the honest exceptions are businesses that genuinely need in-person workshops or multi-channel brand work.
