How much does a freelance SEO cost in the UK?

UK freelance SEO rates run £40 to £150/hour, with most experienced consultants at £75 to £100/hour. Monthly retainers typically sit at £500 to £2,000 for 8 to 20 hours of work. Project rates vary: a technical audit costs £500 to £2,000, a keyword strategy £750 to £3,000, monthly retainers £500 to £2,000. Senior or specialist freelancers can charge £150 to £250/hour.

Can a freelance SEO handle AI search optimisation?

Some can, most cannot. AI search optimisation requires monitoring across ChatGPT, Gemini, Perplexity, and AI Overviews, plus Bing-specific work, plus schema and entity setup. A specialist freelancer who has invested in AI search tooling can deliver, but most generalist freelancers are still primarily Google-focused. Ask directly about platform coverage and tooling before hiring.

When should I switch from a freelance SEO to an agency?

Switch when you need more than 20 hours/month of work, when your scope expands beyond SEO into content production or paid media, when your sector compliance requires specialist review, or when key-person risk becomes unacceptable (the freelancer is your single point of failure). Many UK brands use a freelance SEO for the first 12 to 18 months, then move to an agency as the function scales.

Freelance SEO vs Agency: Which Is Better in 2026?

Q: Freelance SEO vs agency: which is better?

It depends on scope and budget. Choose a freelance SEO (£500 to £2,000/month) for single-channel work, founder-led brands, and projects under 12 hours/month. Choose an agency (£1,500 to £8,000+/month) for multi-disciplinary work (technical SEO + content + AI search + reporting), regulated sectors needing compliance review, and brands needing >12 hours/month of capacity. Freelancers win on price and personal accountability; agencies win on capacity and breadth.

When a freelance SEO is the right call

Founder-led brand, founder is hands-on and wants direct contact
Scope is one specialism (technical audit, content briefs, local SEO)
Budget under £2,000/month
Less than 12 hours/month of work needed
You already have content and design teams in place
Sector is unregulated (retail, hospitality, local services)

When an agency is the right call

Scope spans technical SEO + content + AI search + reporting
Budget £2,000+/month with capacity for growth
More than 20 hours/month of work needed
Sector requires compliance review (financial services, healthcare, legal, regulated B2B)
You need cover for illness, holiday, or staff churn (key-person risk is unacceptable)
You want a tooling stack included rather than seat-licensing your own

The hybrid model

A growing UK pattern: keep a senior freelance SEO on a small retainer (£500 to £1,000/month) for strategy and quality control, plus an agency or in-house team for execution. The freelancer acts as a fractional head of SEO; the agency or team delivers the volume. This works well for brands at £5M to £50M revenue where neither pure-freelance nor pure-agency is the right shape.

The AI search caveat

By 2026, AI Overviews appear on 18% of UK Google searches and ChatGPT search has reached tens of millions of weekly users. Most freelance SEOs are still primarily Google-focused. If AI search visibility matters to your brand, ask any prospective freelancer or agency: which AI platforms do you optimise for, what tooling do you use to monitor citations, and can I see citation data from a current client?
