The short answer
There is no market rate for accountancy SEO in the UK. Published quotes for a practice of 10 to 50 people cluster between roughly £750 and £3,000 a month, and every one of those numbers was set by a firm selling the service. The useful question is not what other practices pay. It is how many new clients the fee has to win before it washes its face, which is arithmetic your own practice can do in ten minutes.
Key takeaways
- Every price on the first page of this search is published by a party that sells search work. None of them is independent and none of them is a market average.
- ICAEW R115.2 forbids your practice from making exaggerated claims or unsubstantiated comparisons in its own marketing. No equivalent rule binds the agency quoting you.
- A monthly fee only means something once you divide it into days. A quote that will not resolve into named people and hours cannot be compared with a second quote.
- The number that decides this is your average fee per client, not the agency's price. At a £2,400 annual fee, a £1,500 monthly retainer needs roughly eight new clients a year before it has paid for itself.
- Competition is local. Two practices of identical size in different towns face different work, which is the honest reason the published ranges are so wide.
The assumption behind this question is that somewhere there is a going rate, and the job is to find it and check the quote against it. It is a reasonable assumption. It is how a practice buys professional indemnity cover or a practice management system.
It does not hold here. Search the question and the first page returns a set of confident ranges: £750 to £2,500 a month, or £2,500 to £8,000 for anything national. Every one of those pages is published by an agency that sells search work to UK accountancy practices. One of them, BCS Media & Design, opens at £3,000 a month and says so plainly, which is more honest than most, but it is still a price list rather than a survey.
Nobody is lying. The error is reading a column of asking prices as though it were market data, and then negotiating against a number that was never evidence in the first place.
Every number you can find was written by a seller
There is no independent price index for UK accountancy SEO, and the absence is structural rather than accidental. Nobody collects it, and the buyers who might publish what they paid are private firms under no obligation to say. We looked for the exception before writing this: the UK does publish every public contract worth over £12,000 including VAT on Contracts Finder, free and without an account. Across the last several thousand awards published there, search work barely appears at all. Public bodies buy campaigns and websites. They almost never buy the thing an accountancy practice is being quoted for.
So the ranges are all there is. Here is what sits behind the numbers on that first page.
| The figure you will see | Who publishes it | What that makes it |
|---|---|---|
| “£750 to £2,500 a month for a practice like yours” | An agency selling retainers to accountancy practices | An opening position, set wide enough to cover every enquiry it might receive |
| “From £3,000 a month” | An agency positioning above the middle of the market | A qualifying filter. The number is there to end conversations early |
| “£300 a month” from a freelancer | One person, often part time | A few hours. Compare the hours, not the headline |
| “The average firm spends X” | Usually the same agencies, citing each other | Not an average of anything measured. Ask who counted, and how many |
You are already held to the standard your supplier is not
ICAEW R115.2 requires a member firm to be honest and truthful in its promotional activity, and prohibits exaggerated claims and unsubstantiated comparisons. A practice cannot claim to provide a better service than a named competitor in the next town, even where that is demonstrably true. The professional behaviour provisions of the Code of Ethics are explicit about it, and a firm remains responsible for marketing carried out on its behalf by somebody else.
Read that against the pitch in front of you. An agency is free to publish a range with no basis and compare itself with competitors it does not name. Your practice would face a conduct question for either.
Hold the supplier to the standard your own regulator holds you to, and ask for the substantiation R115.2 would require of you. The reaction tells you more than the answer does. It is the same instinct behind writing the brief before anyone quotes, which is the single cheapest thing a practice can do to make two quotes comparable.
What the fee has to earn back
The number that settles this is your average fee per client, not the agency's price. A practice billing an owner-managed company £2,400 a year needs a different answer from one billing £9,000, and neither of them can read that answer off a range.
| Your average annual fee per client | New clients needed in year one | What that asks of the work |
|---|---|---|
| £2,400, personal tax and simple limited company | About 8 | A steady flow of small local enquiries. Achievable, and the work has to keep producing |
| £6,000, company accounts with payroll and advisory | 3 | Comfortable, provided the enquiries are the right size rather than merely numerous |
| £12,000, full outsourced finance function | 2 in the first eighteen months | One good client covers most of it, and a year of nothing still costs £18,000 |

Most of the gap between £750 and £3,000 is seniority and hours, and a quote that hides both is not comparable with anything. Ask which named person does the work each month and how many hours they hold. A monthly fee divided by a plausible day rate gives the days you are buying, and the answer is often smaller than the fee suggests.
Four things genuinely change the number, and only one is about the agency.
- How competitive your town is for the searches that matter. A practice in a city of forty competitors is buying more work than one in a market town
- Whether the site can be worked on at all, or has to be rebuilt first, which is a separate project and should be a separate price
- Whether anyone inside the practice will supply technical content, because a supplier writing about tax without a reviewer is a risk you carry
- The seniority actually assigned, which is the one the quote is least likely to tell you unprompted
The supplier's own shape sits underneath all of it. A one-person operation and a twenty-person agency can send an identical proposal, and the headcount behind a supplier is on the public record if you would rather check than ask.
When an accountancy practice should not buy this yet
Three conditions make this premature: no partner owns it, no budget survives a busy season, and the practice is not ready to answer the enquiries it would generate.
The last one is the one we see most often and the one nobody warns about. Search work produces enquiries from people who have never met you and have no referral behind them. A practice whose new client process assumes a personal introduction will lose most of them, and will conclude that search does not work for accountancy firms. The enquiries were fine. Nothing was there to catch them.
There is also a threshold below which this is not worth starting. Under roughly £750 a month you are buying a handful of hours, and a handful of hours of anybody sustains nothing. That money does more as one defined project with a finish line.
We match firms with agencies and are paid by the agency, so a page telling you to wait costs us. What we assess before recommending anyone, including where we decline to introduce anybody at all, is on our accountancy practices page.
Frequently asked questions
What managing partners ask us about SEO pricing.
Is there a market rate for SEO for an accountancy practice?
No, and the ranges published online are not one. They are asking prices, written by firms that sell the service. Two practices of the same size in different towns face different competition, so the work required is different and so is the price of it.
What is a reasonable monthly figure to expect?
Published quotes for practices of this size cluster between roughly £750 and £3,000 a month, and every one of those numbers was set by a seller. Treat the figure as the opening position it is, and judge it against what your firm needs to recover rather than against a range.
Should we pay a monthly retainer or buy a fixed project?
A project suits a practice fixing something specific, such as a site that cannot be found for its own town. A retainer suits continuing work with a partner directing it. If nobody inside the firm has time to direct anything, a retainer buys activity rather than progress.
Does the ICAEW Code of Ethics affect how we market the practice?
Yes. R115.2 requires a member firm to be honest and truthful in promotional activity, and prohibits both exaggerated claims about the services it offers and unsubstantiated comparisons with other firms. A supplier writing copy for you is not bound by that rule, but you are.
How do we tell whether the price includes anyone senior?
Ask which named person does the work each month and how many hours they hold. A quote that will not resolve into named people and days is not one you can compare with a second quote.
