A UK small business pays £500 to £2,500 a month for SEO in 2026, with £1,200 the typical figure. Mid-market companies budget £2,500 to £7,500, and enterprise retainers start at £10,000 and run past £50,000. Retainers have risen 15–30% since 2024, which is why a quote that looked normal two years ago now looks cheap. A one-off audit runs from about £400 for a proper manual review to £15,000 and beyond for an enterprise site, with £900 typical. Our own UK retainers start at £750 a month; what that buys is further down.
The word "retainer" hides what is really being sold. An SEO retainer is a monthly allocation of hours, tools and outreach budget, aimed at whichever part of your site needs it most that month. Two agencies quoting the same £1,200 can be selling very different quantities of work, and the only way to compare them is to ask what the hours go on. This post is built to let you do that.
UK SEO pricing bands, 2026
Indicative, dated to August 2026, and drawn from published UK pricing guides. Most of those guides are written by agencies, so read the ranges as market consensus rather than audited data.
| Band | Typical monthly fee | What the hours usually go on |
|---|---|---|
| Small business | £500 – £2,500 (typical £1,200) | Technical fixes, a handful of pages, local listings, light link work |
| Mid-market | £2,500 – £7,500 (typical £3,500) | A content programme, digital PR, ongoing technical work across a larger site |
| Enterprise | £10,000 – £50,000+ | Multiple markets or brands, dedicated team, developer time built in |
| One-off audit | £400 – £3,000 (typical £900) | Manual technical and content review; automated reports from £100, enterprise to £15,000+ |
What each band actually funds
£500 to £2,500: the small-business band
At the bottom of this band, the retainer covers the essentials and little else: fixing what a crawl turns up, tidying titles and headings, making sure the site is fast and indexable, and keeping local listings accurate. Towards £2,000 there is room for content — a few well-targeted pages a month — and some genuine outreach. What you should not expect at £500 is a content programme and a link campaign at the same time; the hours are not there, and an agency promising both at that price is promising something the fee cannot fund.
£2,500 to £7,500: mid-market
This is where SEO starts to look like a programme rather than maintenance. The retainer funds a steady content output, a digital PR effort that earns real mentions, and continuous technical work on a site large enough to keep generating it. It is also the band where generative engine optimisation — the work of getting cited inside AI answers rather than ranked beneath them — becomes a serious line item, because it needs the entity and brand-mention building that only a sustained budget can do.
£10,000 and up: enterprise
Enterprise retainers are less about SEO tactics and more about coordination: multiple markets, several brands or product lines, and developer time to get changes shipped through someone else's release process. If your organisation is buying in this band, the questions are about process and reporting far more than about price.
The £500 floor, and where it comes from
UK SEO agencies repeatedly cite £500 a month as the point below which no provider can realistically deliver. It is worth being honest about the source: the figure comes from agencies' own pricing guides, and agencies have an interest in setting the floor high. We could find no independent corroboration in forum threads or review sites. Even so, the arithmetic supports it. At the UK's national median day rate of about £500, the fee buys roughly one working day a month before tools are paid for, and a day a month cannot fix, write for and build links to a site. Below the floor, what you are usually buying is reporting on work that is not happening.
What £750 a month buys from us
Our UK retainers run £750 to £3,000 a month by scope and competitiveness, and a one-off technical audit starts at £400. The starting figure sits above the floor the UK market itself describes and below the £1,200 typical, for a reason we would rather state than imply: the work is senior, and it is delivered from India, where our cost base is lower. Roughly half of Western European agency rates for equivalent scope is the honest summary. The full UK price list is on our pricing page.
Whatever the fee, the retainer covers six streams. The fee decides how much of each you get per month, never which ones exist:
- Technical foundation — crawlability, indexation, speed, Core Web Vitals, schema, internal linking
- Keyword and intent mapping — terms you can realistically win, and a plain list of the ones you cannot
- Content that answers the question, in the direct-answer structure AI systems extract from
- Generative engine optimisation — entity, schema and brand-mention work
- Digital PR and link acquisition — earned placements; nothing that risks the domain
- Reporting — rankings, traffic, conversions and AI-citation tracking, monthly, with the reason attached when a month goes badly
VAT, invoicing and the paperwork
For a UK business buying services from a supplier outside the UK, the reverse charge applies: we do not add VAT, and you self-account for it on your own return. Give us your VAT number and it goes on the invoice. Invoices are in pounds, as a zero-rated export of services from India, and payment goes to local GBP account details held through a licensed provider — a domestic transfer, no SWIFT fees. Your accountant will recognise all of this; the mechanics are on our UK and Europe page.
Time zones: the UK is the easy case
India is four and a half to five and a half hours ahead of the UK depending on the season, which means we are online for most of your working day. Questions asked in your morning are answered the same day; work finished in our afternoon is waiting when you arrive. Of every market we serve, the UK is where the overlap is best, and it is the reason a UK client rarely notices where the work is done.
GDPR, stated plainly
Where we process personal data for you — analytics, form data, customer records touched during technical work — we act as a processor under a written data processing agreement, with Standard Contractual Clauses and the UK International Data Transfer Addendum covering the transfer to India. India has no adequacy decision, and we say that rather than wait for your legal team to ask. We do not hold ISO 27001 or SOC 2 and do not claim to; our security and data handling page sets out exactly what we do instead.
Six months is the honest minimum
On a new domain, first movement typically takes four to six months and compounding traffic six to twelve; an established site with authority moves faster. That is why our minimum engagement is six months — not as a lock-in, but as the shortest period over which the work can be judged. Since 2025 there is a second thing to judge it on: on queries that trigger an AI Overview, click-through has fallen sharply, and a retainer that reports rankings alone is telling you half the story. Ours tracks citations as well.
How to compare two UK SEO quotes
- Ask for the hours behind the fee, and who works them
- Ask which of the six streams are in scope this month and which are add-ons
- Ask to see every link earned, with the page it points to
- Ask who owns the content, the accounts and the reporting if you leave
- Ask what is reported beyond rankings — and whether AI citations are on the list
- Treat any ranking guarantee as the end of the conversation
With a market this crowded — one 2026 count put the number of UK digital agencies above 8,500 — the quotes will keep coming. The questions above turn them into something you can actually compare, and a £400 audit turns them into a specific list of what your site needs first.
