How much does SEO cost in the UK?

The short answer: in 2026, UK SEO typically costs £400–£1,500 per month with an independent consultant, £1,500–£5,000+ per month with an agency, or £50–£120 per hour for ad-hoc consultancy. One-off audits usually run £250–£1,000. Anything dramatically cheaper is usually worth exactly what you pay for it.

The long answer is more useful, because the real question isn't "what does SEO cost?" — it's "what should my business pay, and what should I get for it?" Let's break it down.

UK SEO pricing at a glance

What actually drives the price

1. How competitive your market is

Ranking a plumber in Bridgend is a very different job from ranking a personal injury solicitor in central Cardiff. The more businesses bidding for the same searches — and the stronger their existing websites — the more content, links and time it takes to displace them. This single factor explains most of the price range above.

2. Where you're starting from

A technically sound site with some history needs less groundwork than a brand-new domain or a site carrying years of accumulated problems. A good provider will tell you honestly which one you have — that's what an initial audit is for.

3. Who does the work

Agency retainers fund account managers, offices and margins as well as delivery — and at many agencies, the day-to-day work is done by junior staff. With an independent consultant, you're paying for senior hands on your website directly. Neither model is wrong; they suit different sizes of business.

4. Scope

"SEO" can mean a monthly technical health check, or it can mean technical work plus content production plus link building plus AI search optimisation. More scope, more cost. What matters is that the scope is written down — vague retainers are where budgets go to die.

Cheap SEO: why £99/month usually costs you more

There's a floor below which SEO can't be done properly. Real SEO requires research, writing, technical work and outreach — hours of skilled labour. At £99/month you're typically buying automated reports, directory spam, or recycled content, and sometimes link tactics that actively harm your site. The most expensive SEO is the cheap SEO you have to pay someone else to undo.

What should you get for your money?

Whatever the price point, a legitimate engagement includes: a written scope, work you can see (published content, documented fixes, earned links), access to your own data (Google Search Console and Analytics belong to you), and a monthly report that connects the work to rankings, traffic and enquiries — including honestly reporting what didn't work.

How much should a South Wales business budget?

For most local businesses in Cardiff, Newport or Swansea, £400–£900/month is a realistic budget to compete seriously for local searches, rising towards £1,500 for competitive sectors like legal, dental or property. Sustained for 6–12 months, that typically costs less than the equivalent visibility bought through Google Ads — with the difference that rankings persist after you stop paying, and ads don't.

The sensible first step

Don't start with a retainer. Start with an audit — a fixed-price, no-obligation look at where your site stands, what's holding it back, and what it would honestly take to compete. Then you can make the monthly decision with real information. That's exactly how Webolific engagements work, and the initial audit call is free.
