The Best B2B SEO Agencies in the UK (2026), and When a Consultant Beats Them
Published: 3 November 2026 | Last updated: 3 November 2026 | 11 min read
Search "best B2B SEO agencies UK" and the top results are lists.
Many of them are written by B2B SEO agencies, and at least one of those agencies ranks itself first.
That doesn't make those agencies bad.
However, it does mean the list can't tell you the thing you actually need to know: which of these firms will turn organic search into pipeline for a business like yours?
So I've done it differently.
Full disclosure: I'm a B2B SEO consultant, and I'm on this list. I've put myself through exactly the same checks as everyone else, including the ones where I come up short.
In this guide, I'll show you the trust signals I checked, then take you through 11 UK B2B SEO agencies and consultants, grouped by the kind of B2B business each one suits, and when a consultant is the better hire.
Short on time? Here are the key takeaways
- Judge B2B SEO in pipeline: leads, opportunities and revenue, not traffic. Rudo, Directive and Hallam all say they report this way.
- A consultant often beats an agency below about £5m revenue: one senior person who knows your buyer can do more with £2,000 a month than a junior-heavy account.
- Google's AI already has favourites: for "b2b seo consultant" in the UK, its AI Overview cites six firms on this list.
- Published prices are rare: four of the 11 publish a starting price, from £1,425 to £2,400 a month.
- Verifiable reviews are thinner still: only two of the 11 have more than one Trustpilot review.
How I checked every name on this list
I didn't take anyone's word for it, including my own.
- B2B results: a result tied to leads, pipeline or revenue for a B2B client, ideally named.
- A company you can look up: I checked Companies House wherever the business shows a company number or trades under its own name.
- Independent reviews: reviews on Clutch or Trustpilot, where the business doesn't choose what's shown.
- Published prices: a starting price on its own website.
- AI search signal: whether Google's AI Overview cites the firm when UK buyers search "b2b seo consultant".
I checked everything on 2 November 2026.
Nobody paid to be on this list.

Lean B2B teams: hire a senior consultant
If your marketing team is one or two people, an agency retainer often buys you an account manager and a junior executive.
A senior consultant gives you the expensive part, the judgement, without the overhead.
Alkane Marketing (Alastair Kane)
Best for: lean B2B teams that want a senior search consultant on a fixed monthly budget.
- Who does the work: Alastair Kane, an independent consultant who has helped B2B companies with SEO since 2012 and was previously Head of Search at a B2B marketing agency.
- Published prices: B2B SEO retainers from £1,425 to £2,850 a month, according to his B2B SEO page.
- AI search signal: Google's AI Overview cites that page for "b2b seo consultant" in the UK.
- Reviews: his site shows six Google reviews. I didn't find him on Clutch or Trustpilot.
Worth knowing: the site doesn't show a company number or a town, so ask for both before you sign.
GWContent (Graeme Whiles)

Yes, this is me. Here's how I score on the same checks.

Agency or consultant: which should you hire?
Here's how I'd decide.
- Hire a consultant if: you have one or two marketers, a clear product, and pages that need fixing more than content that needs producing.
- Hire a B2B agency if: you need content at volume, SEO run alongside paid and ABM, or reporting into a revenue operations team.
- Either way, ask: "What will you build in the first 90 days, and how will you report it in pipeline?" If the answer is a content calendar and a rankings report, keep looking.

Final Thoughts
The best B2B SEO agency for you is the one that already understands how your buyers choose.
The B2B SEO partners worth hiring aren't the ones that top their own lists. They're the ones who can show you pipeline from organic search, and who let you check.
If you're a B2B tech company and your commercial pages aren't bringing in demos, that's the work I do. Read my case studies, start with a free SEO audit, or get in touch. If you need a bigger team, I'll tell you which agency on this list I'd call.

B2B SEO Agency Frequently Asked Questions
What does a B2B SEO agency do?
A B2B SEO agency gets a business-to-business company found by buyers researching a purchase, then turns that visibility into leads and pipeline. The work usually covers product, comparison and use case pages, technical fixes, content for each stage of a long buying journey, and reporting tied to sales.
How much does a B2B SEO agency cost in the UK?
Few publish prices. Of the 11 UK agencies and consultants in this guide, published starting prices run from £1,425 a month (Alkane Marketing) to £2,400 a month (GWContent), with Rudo at £1,500 and Whitehat SEO at £1,967 ex VAT.
Should a B2B company hire an SEO agency or a consultant?
A senior consultant usually suits a lean B2B team with pages to fix. An agency suits companies that need content at volume, or SEO run alongside paid search and ABM. Either way, ask how results will be reported in pipeline rather than traffic.
How do I check a B2B SEO agency's results?
Ask for a named B2B client with results in leads, opportunities or revenue, and a contact you can speak to. Then look the company up at Companies House and read its reviews on Clutch or Trustpilot rather than its own testimonials.
