How much does SEO cost in the UK in 2026?

What UK businesses pay for SEO

There is no single price for SEO, because you are buying time and skill, and both vary with who does the work. The clearest UK figures come from Whito, which publishes planning ranges by type of provider and re-checks them through the year.¹

A second UK source lands in the same place. Whitehat SEO puts a local business or startup at £500 to £1,200 a month, a growing small business at £1,500 to £3,000 and enterprise work at £5,000 to £20,000 or more.³ Whito's separate study of agency retainers gives £1,000 to £3,500 a month as the typical band for SEO.²

Prices that agencies print on their websites are lower than those ranges. Whito collected 45 published UK monthly prices in June 2026 and found a median of £799. When it re-read the same pages in late October, 38 prices were still published and the median was £837.50.¹ A likely reason is that the firms printing a price are mostly selling fixed packages, while larger retainers are quoted after a call. A published price list shows where the market starts, not where it settles.

What ecommerce brands pay

Sort the same research by the kind of business and ecommerce sits in the upper half.

The reason is scope. A service business needs a handful of pages to rank. A store needs every collection and product page to be found, to load fast and to convert, and Whito's ecommerce band names product page optimisation, category structure and technical fixes as the work behind the price.¹ Whitehat adds that competitive sectors, ecommerce among them, carry a premium of 30 to 50% over its standard ranges.³

If you sell online, budget from the ecommerce band, not from the cheapest package you can find.

What the money should buy

Retainers hide a lot, so it helps to know what the parts cost when they are sold one at a time.

Those prices give you a way to check a retainer. If a store pays £3,000 a month, that is the cost of an audit every month, or of six to twenty articles. So each month you should be able to point at what was done:

• Pages shipped. New or rewritten collections, product pages and buying guides, with their addresses.
• Fixes made. The technical problems found and closed, not a list of problems found.
• What moved. Positions, clicks and orders for the pages that were worked on.
• What is next. The plan for the following month, in priority order.

SEO is rarely the only bill

Rankings alone do not grow a store. Somebody has to write the content, turn visitors into buyers, bring customers back and earn links. Bought separately, each of those has its own monthly price.

Add the bottom of each range and a brand renting all six is at £9,500 a month before anything has improved. That sum is why it matters what a retainer includes. An ecommerce SEO price that covers content and conversion work is a different purchase from one that covers rankings only, even when the monthly figure is the same.

How long before it pays back

Google's own guidance on hiring an SEO says to allow four months to a year from the time changes begin until the benefits show.⁴ Whito gives 6 to 12 months for meaningful results.¹ Anyone promising page one in a few weeks is describing something else.

To work out your own payback, start from your margin and not from traffic. Divide the monthly fee by the profit on one order, and you have the number of extra orders the work must bring in each month. As an illustration, a £2,450 fee, a £60 order and a 60% margin needs 69 extra orders a month to break even. The pricing page has a calculator that does this with your own numbers.

Six questions to ask before you sign

1. What ships each month? Ask for a number of pages and fixes, not a list of activities.
2. Who does the work? Ask who writes the pages and who you will speak to, by name.
3. Who owns what is built? Content, tool accounts, logins and data should stay with you if you leave.
4. What does the contract lock in? Whito treats lock-ins of 12 months or more as a warning sign and prefers three-month rolling terms.¹ We sell six and twelve month plans ourselves, so hold us to the same test: ask what happens if the work is not delivered.
5. How are results reported? Clicks, positions and orders for named pages, every month.
6. What is guaranteed? Google's advice is to walk away from anyone who guarantees first place.⁴ A guarantee about delivery is worth more than a guarantee about rankings.

Where Rembanx sits

For transparency, here are our own prices against the ranges above. Foundation is £2,450 a month, Growth is £3,950 and Flagship is £9,950. The first two sit inside the ecommerce band. Flagship sits above it because it adds digital PR and Klaviyo retention to the SEO, content and conversion work that every plan includes.

The difference is ownership. We build the engine on Claude inside your own accounts, so the skills, playbooks and pages stay with you if you stop. If the first 90 days do not deliver what the plan lists, you can leave owing nothing more, even inside your term.
