In the UK an ongoing SEO service costs between £500 and £5,000 a month, a one-off audit between £500 and £7,500, and an hour of consultancy between £30 and £300. These are the ranges you find on almost every UK pricing page for SEO.
The problem is that hardly any of those pages say where the numbers come from. We read the six UK pricing guides on the first page of Google UK for "how much does seo cost" (September 2026; the other results were a US cost calculator, a Forbes article in dollars and a UK agency's calculator). Five of the six give figures based on the author's own experience, with no sample and no method; the sixth quotes the same international surveys listed below. The only public surveys with a stated sample are four, none of them is UK-only, and they do not say the same thing.
The four surveys that actually exist
None of them measures the UK on its own. All four report figures in US dollars and mix markets with different labour costs, so read them as a reference point, not a price list.
| Survey | Year | Sample | Market | Main finding |
|---|---|---|---|---|
| Ahrefs | 2023, updated 2024 | 439 SEO service providers | global | average retainer $2,917/month, average hourly rate $111, 78.2% work on a retainer |
| SE Ranking with Duda | 2025 | 260 agencies, 78% with fewer than 10 staff | North America, Europe, Oceania | 64% of agencies charge retainers below $1,000/month |
| Backlinko | year not stated | over 300 SEO professionals | global, with a breakdown by region | in the US, UK and Australia the most common band is $2,501-5,000/month |
| Clutch | updated August 2026 | verified reviews across 65,550 companies | mainly United States | $3,199/month on average, $37,159 per project |
The four answers look incompatible, but they are not: each one measured different people. Ahrefs reports an average, and the average of a market with a few very large enterprise contracts rises on its own. Three quarters of SE Ranking's respondents are small agencies, the ones that serve small businesses. Clutch only counts firms that get reviewed on a platform whose typical client is American and has budget. Backlinko gives the most common band rather than the average.
When you compare two quotes, you face the same problem on a smaller scale: two different numbers can describe two different jobs, or the same job sold by two businesses with different costs.
Why European rates sit a step lower, and where the UK fits
SE Ranking's survey is the only one that separates Europe from North America. Above $125 an hour you find 40% of US and Canadian agencies and 6% of European ones. Below $75 an hour you find 23% of North American agencies and 47% of European ones. On retainers the gap narrows but remains: 22% of agencies in North America bill more than $2,000 a month, against 9% in Europe. The survey does not isolate the UK. Backlinko does, and puts it with the US and Australia: in all three the most common band is $2,501-5,000 a month.
The spread is less about skill than about the size of the client. At the start of 2025 the UK had 5.7 million private sector businesses, and 4.3 million of them (75%) had no employees other than the owners. Of the roughly 1.42 million businesses with staff, about 1.15 million have between one and nine employees, according to the Business population estimates 2025 from the Department for Business and Trade. An economy made mostly of businesses with fewer than ten people buys retainers sized for businesses with fewer than ten people. That is why the same UK pricing pages quote entry-level retainers of £300 to £500 a month next to enterprise contracts above £20,000, and why an average on its own tells you little.
The UK price bands, and who wrote them
We opened the six UK pricing guides that rank for this search and lined up the prices they state. The result shows what the industry says it charges. What it actually bills is another matter.
| Item | Lowest figure stated | Highest figure stated |
|---|---|---|
| Ongoing monthly retainer | £300/month | £25,000+/month |
| Hourly rate | £30/hour | £400+/hour |
| One-off audit | £500 | £15,000+ |
| Local SEO | £300/month | £4,000+/month |
| Ecommerce SEO | £1,500/month | £20,000+/month |
| Complete one-off project | £200 | £20,000 |
| Single editorial link | £325 (guest post) | £2,025+ (high-authority site) |
Marketplaces give a lower picture. Bark, which connects UK buyers with freelancers and agencies, states £400-1,500 a month for a retainer and £40-100 an hour, without saying how those figures were worked out. The gap with the agency guides makes sense: much of the demand that goes through a marketplace comes from very small businesses buying a single task, not an ongoing programme.
What a monthly retainer really contains
Here is a real contract from our archive, signed in 2026 with an Italian SME: twelve monthly payments of €1,560, twelve months, three services within the same fee. It is not the right price for everyone; it is an example of what sits inside a figure at that level.
- Ongoing SEO strategy and month-by-month planning, with optimisation of site structure and meta tags
- Guidelines for new pages and optimisation rules handed to whoever writes the content
- Ranking reports and position tracking, with the cost of the tool paid by us
- CMS and server support, with plugin licences included in the fee
- Management of Google Tag Manager and GA4, including updates on consent and Consent Mode
- Google Ads campaign management: CPC, CPA and ROAS optimisation, negative keyword clean-up, ad testing, monthly report
Two items on that list weigh more than they seem. Licences and subscriptions sit inside the fee, so part of the €1,560 is software, not work. And Google Ads management takes a fixed share of time every month, however much the organic side moves: in mixed contracts it is worth knowing how the hours are split, as we explain in the article on synergies between SEO and Google Ads.
A quote is a block of hours dressed up as a retainer
Any monthly figure can be turned into hours, and doing so is the quickest way to see whether two different quotes are selling the same thing. The UK guides above put small agencies at £60-100 an hour, which matches SE Ranking's most common European band of $50-100 (about £38-76 at £1 = $1.3242) at its upper end. At £60 to £100 an hour, a retainer turns into this.
| Monthly retainer | Hours at £60/hour | Hours at £100/hour | Hours per week |
|---|---|---|---|
| £300 | 5 | 3 | about 1 |
| £500 | 8.3 | 5 | 1-2 |
| £1,000 | 16.7 | 10 | 2.5-4 |
| £1,500 | 25 | 15 | 4-6 |
| £3,000 | 50 | 30 | 7.5-12.5 |
The row to look at is the first. £300 a month buys three to five hours, and tool subscriptions come out of that: what is left is not enough to cover a month of work on a site, however small. We have described in detail how much work a very small budget really buys and what happens to a site that buys content below cost.
Do the same division on every quote you receive. If the supplier cannot tell you how many hours it contains, the number they sent you is not the price of a job: it is the price of a subscription.
The four variables that move the price
With the same supplier, the quote changes for reasons you can check yourself before asking for it.
- Where you start from. A site with a sound structure and a few pages to fix costs less than a site that needs rebuilding. If you do not know, an audit will tell you; the UK guides put it between £500 and £15,000+, depending mostly on the size of the site.
- How crowded the niche is. On a local query you have five competitors; on a national query you have fifty, and they have budget. The difference already shows in keyword research.
- How many markets and languages. Each extra country needs its own keyword research, content and links, so it adds a large share of the original fee. None of the UK guides prices it separately, which is a good reason to ask for it line by line.
- How many links and how much content you need. A single editorial link in the UK ranges from about £325 for a guest post to over £2,000 on a high-authority site. A link building campaign can on its own be worth more than the rest of the retainer.
On an ecommerce site the number of pages comes into play: the stated bands for ecommerce SEO start at £1,500 a month and go past £20,000, and the gap depends almost entirely on how many product and category pages need to be kept in order. For a business with physical premises the opposite applies: local SEO is the cheapest item, from £300 to around £4,000 a month.
Freelancer, agency or in-house hire
Ahrefs measures a clear difference between the three: on average $1,348 a month for a freelancer, $3,209 for an agency and $3,250 for a consultant, with agencies charging 138% more than freelancers. By the hour the order flips: $71.59 for a freelancer, $98.90 for an agency, $171.18 for a consultant. A consultant costs more per hour and less per month because they sell a few hours of an experienced person; an agency sells more hours from different people.
The third route is hiring. It makes sense above a certain size and changes the nature of the cost, because a salary is fixed while a retainer can be ended with thirty days' notice: we put the two scenarios side by side in the comparison between in-house SEO and an agency.
How much it has to return to be worth the cost
Work the sum backwards, starting from margin; it is the same calculation that tells you whether SEO is worth it. A £1,000 monthly retainer costs £12,000 a year: if the average margin on a new customer is £500, you need 24 extra customers from organic search to break even, and the sum should be done on the second year because the first is largely investment. If the margin is £5,000, two or three customers are enough and the threshold moves accordingly.
The piece almost always missing from this calculation is time. Rankings do not move in the month you sign the contract, so the first months of fees buy work that will produce revenue later: how much later we measured on real projects in the article on how long SEO takes to show results. To know whether what you are paying for is working before the revenue arrives, you need well-written SEO goals and leading indicators, not a count of positions. The same arithmetic, done properly, is what lets you estimate the return on SEO investment.
When the price is wrong
Three cases where the number on the quote does not add up, and you can see it before signing.
- The retainer cannot be converted into hours because nobody can tell you how many it contains.
- The quote promises rankings. No supplier controls Google's algorithm, and anyone guaranteeing the top position is selling something they do not own.
- The price is identical for three different sites. A package that is the same for everyone describes a standard procedure, not a project.
The questions to ask before signing are few and always the same: we collected them in the list of questions to ask an SEO agency and in the guide on how to choose one. If you would rather start from the work than from the price, our SEO service page shows what we do every month, and our projects show the numbers of what happened, including the case of an industrial manufacturer that went from page nine to position two.
One thing the industry rarely says: the cost that weighs most is not the retainer, it is the cost of changing supplier. Every handover burns two or three months between recovering access, rebuilding history and realigning priorities. An £800 a month contract changed every year costs more than a £1,200 one that lasts three years, and that difference appears on no quote.
Frequently asked questions
The six UK pricing guides ranking for this search quote retainers from £300 to over £20,000 a month; for a small or growing business most of them put the band between £1,000 and £3,000. The SE Ranking survey of 260 agencies in Europe, North America and Oceania (2025) found that 64% charge under $1,000 a month, and that 9% of European agencies bill over $2,000 against 22% in North America.
Because behind the figure there are two different blocks of hours, or two different hourly rates. In the UK the stated hourly rate runs from £30 to over £400: for the same work, five hours a month bought at £300 an hour and at £60 an hour give two very different quotes. Ask how many hours the retainer contains and how much of it is software: only then can you compare.
It depends on how many hours you need. In the Ahrefs survey of 439 providers a freelancer costs on average $1,348 a month and $71.59 an hour, an agency $3,209 a month and $98.90 an hour, a consultant $3,250 a month but $171.18 an hour. A consultant sells a few highly experienced hours, an agency sells more hours from different people: above a certain volume of work the second option costs less per hour.
Between £500 and £15,000+ according to the UK pricing guides that publish a figure. The gap depends on the size of the site and on what is delivered: a thirty-page document with no priorities and no impact estimates is worth less than a plan of fixes ranked by effect against effort. An audit is also the cheapest way to find out where you start before signing an annual contract.
No, it comes down. Once the position is reached, the work moves from building to maintaining: updating pages that lose ground, checking the technical issues that appear with every release, new content on the questions that come up. Those who cut the budget completely after the first year usually see their positions drop over the following twelve months, because competitors keep publishing in the meantime.
