The typical SEO agency cost in the UK is £1,000 to £3,000 a month for a small or medium business. Freelancers often charge 30% to 50% less for comparable work, and mid-sized agencies run from about £3,000 up to £7,000 and beyond. An in-house hire costs more than most people expect once you add salary, tools and management time. Those are indicative ranges, so use them to sense-check quotes rather than to set a budget in stone.
How much does an SEO agency cost per month in the UK?
For small and medium businesses, most UK agency retainers sit between £1,000 and £3,000 a month. Smaller local-only packages start around £400 to £800. Larger or more competitive campaigns run to £3,000 to £7,000. Published guides such as this UK pricing breakdown and this 2026 price review report broadly similar bands, and both note that prices have risen in recent years. They come from agencies, so weigh them accordingly.

Agency, freelancer or in-house: which costs less?
A freelancer usually costs the least per hour of skilled work, but you get one person’s skills and one person’s holiday calendar. An agency costs more and brings a team with writers, developers and analysts under one roof. An in-house hire gives you full-time focus but a salary of £30,000 to £55,000 plus tax, benefits, software and training before they produce a single page.
For most small businesses, a freelancer or small agency makes sense first. In-house starts to pay when SEO is central to the business and there is enough work to occupy one person for the whole week.
What does an SEO retainer usually include?
A decent retainer covers technical monitoring and fixes, keyword and competitor research, on-page improvements, a set number of new or refreshed pages, local profile management and reporting. Better ones add a monthly strategy call and conversion advice. Content writing, developer time and paid outreach are commonly extra.
Ask for the monthly hours or deliverables in writing. “Ongoing optimisation” is not a deliverable.
How long are SEO contracts?
Many agencies ask for six or twelve months, because results compound slowly. Rolling monthly agreements exist and are a sign of confidence. Whatever you choose, check the notice period, what happens to your accounts and content on exit, and whether the agency will hand over reports, access and documentation without a fight.
Our post on how long SEO takes explains why twelve months is often used and when it is worth accepting.
What should you look for in an SEO proposal?
A strong proposal reads as though it was written for you. It names your competitors, shows what is holding your site back, lists the first ninety days’ tasks and says how success will be measured in enquiries or sales. A weak proposal is a menu of packages with prices and a list of features that could apply to anyone.
Check that the proposal tells you who will do the work, how often you will speak, and what you will own at the end. Also look for what is honestly outside scope.
Does a higher fee mean better SEO?
Not always. A higher fee buys more hours and more senior attention, but it does not guarantee either. Judge value by the clarity of the plan and the quality of the examples, not the size of the invoice. A £1,200 retainer that delivers six strong pages and a monthly call beats a £2,500 retainer that delivers a graph.
What should you ask an SEO agency before you sign?
Six questions separate agencies that will do the work from agencies that will sell it.
- Who will actually work on my account, and how many hours a month will I get?
- Which pages and tasks will you deliver in the first ninety days?
- How will you measure success in enquiries, not just rankings?
- What is not included in this price?
- Who owns the content, accounts and reports if we part ways?
- Can I speak to a client with a similar business?
A good agency answers these in writing and without fuss. Hesitation on the first two is worth noting.
What does a typical year of SEO spend look like?
Take a small business paying £1,500 a month. Over twelve months that is £18,000. Spread across a year, the first quarter mostly goes on groundwork and quick wins. Pages mature and enquiries rise through the middle of the year. By the final quarter a well-run campaign is usually producing steady leads without needing proportionally more spend.
If an average customer is worth £2,000 to you, that campaign pays for itself with about nine customers across the year. If a customer is worth £200, you would need ninety, and SEO may not be the right first channel.
How do you work out what SEO is worth to you?
Take the value of an average customer, multiply by the share you could realistically win, and compare that with a year of fees. Most businesses find SEO becomes attractive once it is worth about three times its annual cost. Pair it with a modest paid campaign while it builds; our SEO service and PPC service are designed to work together for exactly that reason.
Frequently asked questions
Is £500 a month enough for SEO?
For a local trader in a quiet market, it can cover the essentials. In a competitive city sector, it will not be enough on its own.
Why do SEO quotes vary so much?
Scope, competition and seniority, mostly. Compare what you get, not what you pay.
Should I pay for SEO upfront?
Monthly in arrears or monthly in advance with a short notice period is standard. Large upfront payments for work that has not started deserve a second look.
Can an agency guarantee first-page rankings?
No. Google’s own guidance says nobody can promise a top position, and anyone who does is selling something else.
