Most small UK businesses pay between £500 and £850 a month for Google Ads management. Below roughly £4,000 of monthly ad spend, a flat fee around £500 is the norm. Above that, fees usually scale with spend, and by the time an account is running £50,000 a month you are looking at something closer to £3,000. That is the management fee only. It sits on top of whatever you pay Google.
Those are our own published numbers, not an industry survey. You can drag the slider on our pricing page and see the exact fee for any spend level. Most agencies will not show you that, which is really the point of this article: the range is not a secret, and the reason fees differ is not mysterious either.
What are the three ways agencies charge for Google Ads?
Almost every quote you receive will be one of these.
A flat monthly retainer. You pay the same fee every month regardless of what you spend. Simple to budget for, and the most common shape at the small business end. The risk is that a flat fee stops making sense in both directions: too high for a tiny account, and quietly too cheap for the agency once your spend triples, at which point the attention you get tends to drop.
A percentage of ad spend. Typically 10% to 20%, sometimes with a minimum fee attached. It scales automatically, which is tidy. It also means the person advising you on your budget gets paid more when you spend more. That conflict is real, and you should at least name it before signing.
A hybrid, or a banded fee. A base fee that steps up as spend grows. This is what we use. The fee tracks the workload without paying anyone a commission on your budget increases.
There is a fourth model you will occasionally see, performance-based pricing, where the fee is tied to leads or revenue. It sounds appealing and it is usually a poor fit for small accounts, because attribution at low volume is too noisy to settle an invoice on.
Why does the management fee go up as my ad spend goes up?
This is the question that annoys people most, and it deserves a straight answer.
It is not because a bigger budget takes proportionally more hours. It does not. A £40,000 account is not eight times the work of a £5,000 one.
It goes up because the cost of getting it wrong goes up. At £2,000 a month, a mistake that wastes 20% of budget costs you £400. At £40,000 a month, the same mistake costs £8,000. Larger accounts get checked more often, get more structural work, and get more of the analysis that stops small problems compounding. You are buying a higher standard of care, not more hours.
The honest version is that fees scale with risk and with the value of the outcome, not with effort. Anyone telling you their fee is a pure reflection of time spent is either not tracking their time or not telling you the truth.
What should be included for £500 to £850 a month?
At the small business end, a retainer in this band should cover all of the following. If a quote leaves things out, ask why.
The checklist for a small business retainer
- Ongoing campaign management: bids, budgets, structure, and pacing against your monthly cap
- Search term review and negative keyword work, so you stop paying for irrelevant clicks
- Ad copy written and tested, not left untouched for a year
- Conversion tracking that is actually verified, not just installed
- Monthly reporting that explains what changed and why, in plain English
- A named person who answers your emails
What is usually charged separately?
Landing page design and build, creative production for display or video, feed management for ecommerce, and any platform beyond Google. Microsoft Ads in particular is usually quoted as an add-on, often a couple of hundred pounds a month, because it is a separate account to manage even though it borrows heavily from the Google setup.
How much ad spend do you need before management is worth paying for?
Roughly £1,500 to £2,000 a month, as a working floor.
The arithmetic is simple. If you are spending £800 a month on ads and paying £500 to have them managed, 38% of your total marketing outlay is going to management. The account is unlikely to have enough data to optimise meaningfully anyway, and the fee cannot pay for itself at that volume.
Below that floor you have two better options: run it yourself and accept it will be rough, or pay for a one-off setup and audit and then take it over. Both are more honest uses of your money than a retainer that mathematically cannot work.
Does a freelance consultant cost less than an agency?
Usually yes, but the gap is smaller than people expect, and it is not the main reason to choose one.
An agency carries account managers, sales, offices and overhead, and that shows up in the fee. A freelance consultant carries almost none of it, so more of what you pay goes into the actual work. The trade-off is capacity and cover: a solo consultant has a hard ceiling on clients and no one to step in during a holiday.
The more useful question is not which is cheaper but who is actually going to touch your account. At the small business end of agency pricing, the person doing the work is often the most junior person in the building. That is not a scandal, it is just how the economics work at that price point. Ask directly, before you sign, who will be in the account week to week and how many other accounts they handle.
What are the warning signs in a Google Ads quote?
- No minimum spend mentioned. An agency happy to take a retainer on £600 a month of ad spend is taking your money knowing it cannot work.
- A percentage fee with no cap. Fine at £3,000 of spend, uncomfortable at £30,000, and the incentive points the wrong way.
- Long lock-ins on a new relationship. Three months to prove something is reasonable. Twelve is not, before either side knows if it fits.
- Vague deliverables. “Ongoing optimisation” is not a deliverable. Ask what gets checked, and how often.
- They will not tell you the price until a call. Pricing that only exists behind a sales conversation is pricing designed to be adjusted to what you look like you can afford.
- Guaranteed positions or guaranteed leads. Nobody controls the auction. A guarantee here is a sales tactic.
So what should you actually budget?
If you are spending under £4,000 a month on ads, budget £500 a month for management and treat anything much above that as needing a specific justification.
If you are spending £10,000, expect somewhere around £850. At £50,000, expect around £3,000. Somewhere between those points is a straight line, and any agency worth hiring should be able to tell you where you sit on it without a discovery call first. Our pricing page will give you the number in about five seconds.
- £500 to £850 a month is the realistic UK range for small business Google Ads management, on top of your ad spend.
- Fees scale with spend because the cost of mistakes scales, not because bigger accounts take proportionally more hours.
- You need roughly £1,500 to £2,000 a month in ad spend before a retainer can pay for itself.
- Percentage-of-spend pricing creates a real conflict of interest. It is not disqualifying, but name it before you sign.
- Ask who will actually be in your account each week. At small business price points the answer is often a junior, whoever the logo on the door is.
Frequently Asked Questions
Is the management fee separate from what I pay Google?
Yes, always. Your ad spend goes directly to Google. The management fee is what you pay the person running the account. A quote of £500 a month with a £2,000 ad budget means £2,500 leaving your business each month.
Do I have to sign a long contract?
You should not have to. A short initial term of around three months is reasonable, since a new account genuinely needs a few months before performance means anything. Anything longer on a first engagement is protecting the agency, not you.
Is VAT included in these figures?
The figures quoted here are before VAT. UK agencies and consultants registered for VAT will add it at the standard rate. If you are VAT registered yourself you will reclaim it, so it is a cash flow question rather than a cost.
What does Microsoft Ads cost on top?
Usually a few hundred pounds a month as an add-on, rather than a second full fee. The strategy carries across from Google, but it is still a separate account that needs its own management, so it is rarely free.
Can I just run Google Ads myself?
For a small local business with a handful of obvious keywords, yes, and plenty do. It gets harder fast once you are spending real money, running Shopping or Performance Max, or competing in an auction where everyone else has help. A sensible middle route is paying for a proper setup and a follow-up audit, then running the day to day yourself.
