Quick answer: To choose a PPC agency, ask five things before signing: will you own the Google Ads account and data, what exactly the fee covers versus your ad spend, how success is measured and reported, who personally manages the account, and whether there’s a lock-in contract. A transparent agency answers all five plainly — evasion is the biggest red flag.
Hiring a Google Ads agency is one of the easier marketing decisions to get wrong. The work is invisible, the jargon is dense, and the results take weeks to judge — so a smooth sales pitch can hide a weak operator for months while your budget quietly drains. The good news is that a handful of direct questions will separate a genuine specialist from a reseller before any money changes hands.
This guide gives you the exact questions to ask, what a good answer sounds like, the red flags that should end the conversation, and the fair market rate for PPC management in the UK in 2026.
Why choosing the right PPC agency matters
It matters because paid search is now the single largest slice of UK advertising, and the money at stake is real. According to the Advertising Association / WARC Expenditure Report, UK advertisers invested £46.7 billion across all media in 2025, and search took the biggest share at 38.3% — roughly £17.9 billion, growing 5.8% year on year. The same report forecasts total UK ad spend rising to £49.8 billion in 2026. That is the pool you’re competing in.
The stakes are high because clicks are expensive and getting more so. WordStream’s 2025 Google Ads benchmarks put the average cost per click at around $5.26, with legal services highest at $8.58; in competitive UK verticals like law and finance a single click can cost £10 or more. A well-run account turns that spend into profit — independent benchmarks from WebFX treat a 2:1 return on ad spend (200% ROAS) as a baseline and 4:1 as strong. A poorly run one hands the same budget to Google with nothing to show. The difference is almost entirely the person managing the account.
The 7 questions to ask a PPC agency before you hire
The best questions force specifics. Vague reassurance is easy; a precise, unhesitating answer is what you’re actually buying. Ask these seven and listen for how directly they’re answered.
- Will I own the Google Ads account and keep it if we part ways? The correct answer is an unqualified yes. Google Ads Help is explicit that accounts should be owned by the advertiser, with the agency requesting access by linking its Manager (MCC) account — never the other way round.
- What does your fee cover, and what do I pay Google directly? There are always two bills: the management fee and the ad spend. A good agency draws that line clearly and bills your card directly for spend.
- How will we measure success, and what does reporting look like? Look for conversions, cost per lead or sale, and ROAS — not clicks and impressions dressed up as wins.
- Who will actually run my account day to day? Ask to meet them. The person in the pitch is rarely the person doing the work.
- What’s your contract length and notice period? Confidence shows up as short notice periods and month-to-month options.
- Can you show results for a business like mine? Specific, verifiable case studies beat logos on a wall.
- How do you handle conversion tracking and attribution? If they can’t explain how a lead is counted, they can’t prove they’re working.
How much should PPC management cost in the UK?
Most UK SMEs pay £500–£1,500 a month in management fees, separate from ad spend, or 10–20% of spend under a percentage model. Freelancers charge £50–£100 an hour; full-service agencies with strategy, landing pages and tracking run £2,000–£5,000+ a month. Independent UK data from Addictive Digital puts the average PPC retainer at around £1,040 a month, and reporting collated by PPC.io notes that most businesses spending £1,000–£100,000 a month settle into a 5–10% management fee as budgets scale up.
| Route | Typical UK management cost | Best for |
|---|---|---|
| Freelancer | £50–£100/hr, or £300–£1,000/mo | One campaign, defined scope |
| SME agency (flat retainer) | £500–£1,500/mo | SMEs spending £1k–£5k/mo on ads |
| Full-service agency | £2,000–£5,000+/mo | Growth & e-commerce accounts |
| Percentage of spend | 10–20% (SME); 5–10% at scale | Larger or seasonal budgets |
| In-house hire | £30k–£45k salary + tools | Constant, high-volume activity |
Price alone tells you little. A £500 retainer that grows your leads is cheaper than a £2,000 one that reports busywork. Anchor the fee to what it delivers, and compare quotes on the same scope.

Agency, freelancer or in-house — which route fits?
Choose by the size and consistency of your budget, not just the sticker price. If you spend under £2,000 a month on ads and run a handful of campaigns, a specialist freelancer or a lean SME agency is usually the right call — you get senior attention without the overhead. Once spend passes roughly £5,000 a month, or you’re running e-commerce feeds, multiple markets and landing-page work, a full-service agency earns its fee through faster optimisation cycles and better tracking.
An in-house hire only makes sense when paid search is constant and high-volume: a competent PPC manager commands a £30,000–£45,000 salary before tools and training, so you need enough sustained activity to justify a full-time seat. Whichever route you pick, the decisive factor is who touches the account each week. Given that average click costs sit above $5 and climb well beyond £10 in law and finance, a few hours of skilled optimisation a month can move more money than the entire management fee. Buy the operator, not the logo.
PPC agency red flags to walk away from
The single biggest red flag is an agency that owns your Google Ads account. If the account is created under the agency’s name rather than yours, you lose your campaign history, conversion data and, often, your ability to leave without starting from scratch. Paid-media consultant Sarah Stemen lists agencies retaining account ownership and refusing to hand over access among the clearest warning signs that a relationship will trap you. Insist, in writing, that the account and all data are yours.
Other red flags worth ending the conversation over: a hidden margin on your ad spend (where the agency marks up what you think you’re paying Google), reporting that celebrates clicks and impressions instead of leads and revenue, guaranteed “#1 positions” (impossible to promise on an auction), long lock-in contracts with no exit, and an inability to explain how conversions are tracked. Any one of these on its own is a reason to keep looking.
Green flags of a good PPC agency
A good agency is boringly transparent. You own the account; the management fee is clearly separated from ad spend billed to your own card; reporting leads with cost per acquisition and ROAS; a named specialist — not a rotating pool — runs the account; contracts are month-to-month or carry a short notice period; and they’re honest about what won’t work for your budget rather than promising the moon. As WordStream’s benchmark data shows, results vary enormously by industry, so a trustworthy partner sets expectations against real sector benchmarks instead of generic hype.

Frequently asked questions
How do I choose a PPC agency?
Shortlist two or three specialists, then ask each the same questions: will you own the account, what does the fee cover versus ad spend, how is success measured, who runs the account, and what’s the contract length. Choose the one that answers most directly and can show relevant results — not the cheapest or the flashiest.
What are the biggest PPC agency red flags?
The agency owning your Google Ads account, a hidden margin marked up on your ad spend, reporting only clicks and impressions, guaranteed rankings, long lock-in contracts, and being vague about conversion tracking. Any of these is a reason to walk away.
How much should I pay for PPC management in the UK?
Most UK SMEs pay £500–£1,500 a month, or 10–20% of ad spend, with the average retainer around £1,040. Ad spend paid to Google is always on top. Larger accounts drop to 5–10% of spend as budgets scale.
Should the agency or I own the Google Ads account?
You should. Google recommends advertisers own their account while the agency requests access via its Manager (MCC) account. Owning it means you keep your history and data if you ever change agencies.
How long before PPC delivers results?
Expect two to four weeks for early signal and eight to twelve weeks for meaningful optimisation, as the account gathers conversion data. Be wary of anyone promising instant results — auctions and learning periods take time.
