How Much Does an SEO Agency Cost in the UK?

The figure on its own tells you very little, though. What matters is how many hours that fee buys, who does the work and what is left out.

We price and deliver SEO retainers every month, so this guide sets out the published benchmarks, explains what moves the price and shows you how to read a quote so you can compare agencies on substance rather than headline cost.

What UK SEO agencies charge

There is no official price list for SEO, and most agencies do not publish theirs. The most useful benchmarks come from independent research and provider surveys.

Two caveats are worth knowing. The Ahrefs survey is global and priced in US dollars, so treat it as a sense check rather than a UK price. Whito’s UK figures come from agency rate cards and industry surveys collected between January and May 2026, and it notes that retainers have risen by more than 30% since 2023.

What your monthly fee actually buys

An SEO retainer is, in practice, a block of specialist time each month. Converting a quote into hours is the quickest way to compare two agencies fairly.

The hourly rate varies by agency and seniority. Ahrefs found agencies averaged around $99 an hour globally, while UK guides commonly quote £60 to £150. Using illustrative rates:

That time has to cover research, technical fixes, content, reporting and account management. At the lower end, there is enough for focused work on a small site. Larger sites, ecommerce catalogues and competitive sectors need more, which is why their retainers sit higher.

Always ask an agency how many hours the fee includes and who does them. A senior strategist and a junior executive can both appear on the same invoice.

What pushes the price up or down

• Competition. Ranking a local service business is a different job to competing with national brands in finance, legal or retail.
• Size and condition of the site. A 20-page brochure site with a clean build needs far less technical work than a 5,000-product shop with legacy redirects and duplicate pages.
• Content volume. Content is often the biggest variable cost. Two well-researched articles a month and eight are very different scopes.
• Digital PR and links. Earning genuine coverage takes time. Be cautious of quotes promising a fixed number of links each month, as that usually means paid or low-quality placements.
• Who does the work. Senior-led boutiques and large agencies with account directors carry different overheads, and London agencies generally charge more than regional ones.
• Reporting depth. Monthly reporting tied to leads and revenue takes longer to produce than a rankings export, and is worth paying for.

The four ways agencies charge for SEO

Retainers dominate because SEO is ongoing work. Rankings move as competitors publish, Google updates its systems and your own site changes.

How to read an SEO quote

Before you sign, get clear written answers to these questions:

1. How many hours a month does the fee include, and who carries them out?
2. What are the deliverables each month (technical fixes, pieces of content, pages optimised, reports)?
3. What is out of scope, and what does extra work cost?
4. Are tools, content writing and development time included or billed separately?
5. Are Google Search Console, Google Analytics and any content produced set up in your name?
6. What is the minimum term and notice period? Is the price quoted with or without VAT?
7. How will success be measured? Look for leads, enquiries or revenue, not only rankings and traffic.

Red flags to watch for

• Guaranteed rankings. Google’s own guidance on hiring an SEO states that no one can guarantee a number one position.
• Secret methods. A reputable agency can explain what it is doing and why.
• A fixed number of backlinks per month. Links worth having are earned, not ordered in bulk.
• Being locked out of your own accounts. If you leave, your data should leave with you.
• Prices well below the market. At £300 a month there are only a handful of hours to work with and cheap link building can create problems that cost more to fix later.

Is an agency the right option for your budget?

Not always. If your budget is under around £500 a month, a few days of consultancy to fix the fundamentals, followed by doing the work yourself, may deliver more than a minimal retainer. If you need significant daily capacity, an in-house hire may make more sense.

Frequently asked questions

How much does SEO cost per month in the UK? The typical range for a UK agency retainer is £1,000 to £3,500 a month. Smaller local campaigns can come in under that, and national, ecommerce or international work usually sits above it

Is a freelancer cheaper than an agency? Usually, yes. Ahrefs found freelancers charge less than half the average agency retainer. The trade-off is capacity, breadth of skills and cover for holidays or illness.

How long before SEO delivers results? Most businesses see early movement within three to six months, with the strongest returns building over a year or more. Plan your budget around that timeline rather than a single month.

Does SEO pricing include content and links? It depends on the agency. Some include content and digital PR in the retainer, while others charge for them on top. Ask for a written breakdown before you sign.

Setting a budget you can judge

The right SEO budget is one you can measure. Agree what the fee buys in hours and deliverables, tie reporting to enquiries or sales, and review it after six months against those numbers.
