Google Ads Management Fees in the UK, Explained

There are two numbers in paid search and people routinely confuse them. There is what you pay Google, which is your media budget and goes straight to the auction. And there is what you pay whoever runs it, which is the management fee. This article is about the second one.

Three models dominate the UK market, and one of them has a problem built into it that nobody volunteers.

The three models, and rough UK bands

Flat monthly fee. You pay a fixed amount regardless of what you spend with Google. At the small end, expect somewhere in the region of £300 to £700 a month for a single-market account with a handful of campaigns. Mid-sized accounts commonly sit between £700 and £1,500. Larger or multi-market accounts go well beyond that.

Percentage of ad spend. Typically somewhere between ten and twenty per cent of what you spend with Google, almost always with a minimum monthly fee — often several hundred pounds — because below a certain account size the percentage does not cover the hours.

Hybrid. A smaller base fee plus a percentage above a threshold, or a base fee plus a bonus tied to an agreed result. Increasingly common, and generally the most sensible of the three.

Also encountered: hourly consulting for people who want an expert to look at an account periodically rather than run it, and setup fees for building an account from nothing, which is a genuinely separate piece of work from running it.

These bands reflect the visible UK market rather than a survey, and the spread is wide because “management” means very different things at different agencies. One firm’s fee covers strategy, build, weekly optimisation, landing page advice and monthly reporting. Another’s covers logging in occasionally and sending an automated report. Compare the work, not the number.

The incentive problem in percentage pricing

Say it plainly, because it is the thing you are least likely to be told.

If your agency charges a percentage of your ad spend, then every time they persuade you to spend more with Google, they earn more. Their income rises with your costs, not with your results.

That is not an accusation of dishonesty. Most agencies charging this way are perfectly straight and would recommend the same things on any fee model. But the incentive is real and it points the wrong way, and it shows up in small, deniable ways rather than in outright bad advice:

• A reluctance to pause campaigns that are marginal but large.
• Recommending broader targeting or additional networks, which spends budget faster.
• Framing a rising spend as growth without holding the cost per enquiry to account.
• Little enthusiasm for the recommendation that would help you most and pay them least — spend less, more precisely.

The clearest tell is what happens when the account is working well. If your cost per enquiry has come down and the honest advice is “hold the budget here, the extra spend converts worse”, does your agency say it? On a percentage model, saying it costs them money.

Percentage pricing does have a defensible logic. Larger accounts genuinely take more work — more campaigns, more products, more markets, more reporting. The fee scaling with account size is not absurd. It is the direction of the incentive that deserves scrutiny, not the arithmetic.

What to ask before you sign

The model matters less than whether the incentive is pointed at your result. Put these to any agency, including us:

• If cutting my budget were the right advice, would your fee fall as a result?
• What is the fee tied to — my spend, a defined scope of work, or a result?
• What happens to the fee if my account grows, and who decides that?
• At what spend level would you tell me not to hire you at all?

That last question is the useful one. Below roughly £1,000 a month in ad spend, most management arrangements struggle to justify themselves — the fee becomes a large share of the total, and you are often better running it yourself for a while and coming back when the numbers justify help. Paying an agency more than you pay the platform rarely makes sense, and an agency that will not say so is worth a second look.

Our own fees depend on scope, so they are a conversation rather than a number on a page. What we will commit to in writing is which model applies and what it is tied to, before you sign anything.

What the fee should buy

Regardless of model, a management fee should cover work you can see evidence of:

• Search terms review. Actually reading what people typed, and excluding what should not have matched. This is the single highest-value recurring task and the first thing that gets skipped.
• Conversion tracking that is verified, not assumed. If nobody has confirmed the conversion action fires correctly, every number in every report is decoration.
• Bid and budget decisions with reasoning attached.
• Ad copy testing, with old variants retired rather than left running.
• Landing page feedback. The account cannot fix a page that does not convert, but whoever runs it should be telling you which page is the problem.
• A report you can understand, ending in enquiries and cost per enquiry rather than impressions and click-through rate.

If you cannot point to those happening, you are paying for access to a login.

Questions to ask before signing

• What exactly does the fee cover each month, and what is extra?
• Who owns the Google Ads account — is it under my billing, in my name?
• What is the notice period, and what happens to the account if I leave?
• How is your fee affected if I halve my budget?
• What would make you tell me to stop advertising?

That third question matters more than people realise. If the agency’s own account holds your campaign history, leaving means starting again, and that is a lock-in disguised as a convenience. Your account should be yours, with the agency granted access.

The last question is the honest one. Anyone who cannot describe a situation in which they would advise you to spend nothing is selling spend rather than advice.

When the answer is not to pay anyone

If you are spending under a few hundred pounds a month, no fee model works well. Management costs would swamp the media budget. Run a small, tightly controlled campaign yourself, keep the targeting narrow, check the search terms weekly, and revisit when spend is high enough that a percentage point of improvement is worth more than the fee.

If your website converts poorly, fix that before paying anyone to send more traffic to it. Advertising into a weak page is a way of paying to discover the page is weak.

Our approach to Google Ads is set out in full, and the web analytics work is usually where we start, because a campaign judged on broken tracking is worse than no campaign at all. If you want a straight view on whether management is worth it at your spend level, ask us.
