Quick answer: Most London businesses pay between £1,000 and £5,000 a month for an ongoing SEO retainer in 2026. Local SEO for a single-location business can start at around £500 to £1,500 a month, competitive national campaigns usually run £3,000 to £8,000, and enterprise programmes start at about £7,500 and can pass £20,000. One-off SEO audits typically cost £1,500 to £7,500, and London agencies tend to charge 15 to 35% more than equivalent regional providers.
SEO pricing is hard to compare because agencies package it differently. One firm’s £1,500 “growth package” might be ten hours of technical fixes, while another’s covers four articles, link building and reporting. London adds another layer: the capital has some of the most competitive search results in the UK, especially in legal, financial, property and professional services, and agency salaries and rents are higher.

SEO Pricing Models Explained
London SEO providers use three main pricing models, often in combination.
Monthly Retainers
A retainer is a fixed monthly fee for an agreed scope of ongoing work: technical fixes, content, digital PR or link building, and reporting. It is the most common model because SEO results build over months. Retainers usually come with a minimum term of three to twelve months.
Project Fees
Projects cover defined pieces of work such as an SEO audit, a site migration or a keyword and content strategy. Visionary Marketing, which has offices in Newcastle and London, puts typical project pricing for audits, migrations and builds at £1,500 to £15,000 in its 2026 SEO pricing guide, based on pricing data from 47 UK agencies collected in Q1 2026. Whitehat SEO, a London agency on Uxbridge Road, puts SEO audits at £500 to £7,500 and website migrations at £1,000 to £15,000 in its UK SEO costs guide.
Hourly And Day Rates
Consultants and freelancers often bill by the hour or day, which suits training, ad hoc advice or supporting an in-house team. Whitehat lists freelancers at £40 to £100 per hour, agency consultants at £70 to £300 or more, and London specialists at £250 to £400 or more per hour for strategic work. Visionary Marketing gives a senior-led agency blended rate of £110 to £180 per hour and says London and South East freelancers start at about £75 per hour. For freelance day rates, Whitehat quotes £200 to £400 for junior SEOs, £400 to £700 for mid-level and £700 to £1,200 or more for senior specialists.

Sources: Visionary Marketing (Q1 2026 data from 47 UK agencies) and Whitehat SEO (April 2026). These are UK figures. Visionary Marketing estimates that London agencies are typically 15 to 35% more expensive than equivalent regional providers, so a £3,500 regional retainer would be roughly £4,200 to £4,700 in central London.
Local Vs National Vs Enterprise SEO In London
Local SEO
Local SEO focuses on Google Business Profile, map pack rankings, local landing pages, reviews and citations. Visionary Marketing puts local services SEO at £500 to £2,000 per month, and Whitehat suggests £800 to £1,500 for local businesses in low-competition niches. Whitehat’s own published price list shows local SEO at a £1,000 set-up fee plus £400 per month. In London, competition varies sharply by borough and sector: a dentist in Islington or a solicitor in the City will need more work than a plumber in an outer borough.
National SEO
National campaigns target UK-wide keywords, which means more content, more digital PR and stronger technical foundations. Whitehat puts national or competitive sector SEO at £3,000 to £8,000 or more per month. Its own published SEO retainer starts at £1,967 per month, and its SEO plus content package starts at £2,967 per month, which gives a sense of where a London specialist agency’s entry point sits.
Enterprise SEO
Enterprise SEO covers large sites, multiple markets or languages, and work that has to fit around engineering roadmaps and legal sign-off. Visionary Marketing puts enterprise retainers at £7,500 to £15,000 or more per month, and Whitehat quotes £10,000 to £50,000 or more for international enterprise programmes. Many of London’s larger agencies work at this level, often combining SEO with digital PR and analytics.
Freelancer Vs Agency
Whitehat estimates that freelancers charge £300 to £2,500 per month and are typically 30 to 50% cheaper than agencies for equivalent work, while agencies charge £1,500 to £20,000 or more. It suggests freelancers for budgets under about £2,000 a month and agencies above about £2,500, particularly when you need technical, content and link building skills together.
A good freelancer can outperform a weak agency, so the label matters less than who actually does the work. Ask any provider who will run your account day to day, how many hours a month your fee buys, and what the split is between technical work, content and links. Our list of the top SEO companies in London includes both large agencies and specialist independents if you want a starting shortlist.
What Is Included At Each Budget Level
Whitehat links its retainer bands to the hours you can expect each month, which is a useful way to judge whether a quote is realistic:
Business Size
Monthly Cost
Typical Hours Per Month
Local or startup
£500 to £1,200
5 to 10
Growing SME
£1,500 to £3,000
15 to 30
Mid-market B2B
£2,500 to £5,000
30 to 50
Enterprise
£5,000 to £20,000+
50 to 100+

At five to ten hours a month, an agency can maintain a local profile, fix priority technical issues and produce a short report, but it cannot also write regular content and build links. If a provider promises everything for £500 a month, ask how the hours add up. Content is often the biggest variable: Whitehat prices 1,000-word articles at £80 to £300 each, and its own content creation service starts at £450 per article.
What Pushes SEO Costs Up In London
Competition. Legal, finance, property, recruitment and private healthcare are some of the hardest sectors to rank in, and many competitors are headquartered in London.
Site size and condition. Large or older sites need more technical work, especially after migrations or platform changes.
Content volume. Regular articles, landing pages and expert-reviewed content add up quickly.
Digital PR and links. Earning coverage on national publications is labour-intensive. Whitehat’s backlink building service, for example, starts at £528 per month on its published price list.
AI search visibility. Many agencies now sell answer engine optimisation alongside SEO. Whitehat lists AEO services from £1,967 per month, priced in line with its core SEO retainer.
Overheads. Central London salaries and office costs feed directly into day rates.
Agency Vs In-House SEO
Some London businesses compare an agency retainer with hiring an SEO specialist directly. Visionary Marketing estimates that a senior in-house SEO costs £85 to £120 per hour once salary, employer costs and tools are included, compared with a senior-led agency blended rate of £110 to £180 per hour. The in-house hire is cheaper per hour, but one person rarely covers technical SEO, content, digital PR and analytics equally well, and you also carry recruitment time, management and holiday cover.
A common pattern for growing London companies is a hybrid: an in-house marketer owns content and day-to-day priorities, while an agency or consultant handles technical audits, migrations and link building on a smaller retainer or project basis. This can keep monthly agency spend in the £1,000 to £2,500 range while still giving access to specialist skills when they are needed.
How To Judge An SEO Quote
When comparing proposals, ask each agency for a written scope that lists the deliverables and hours per month, the people assigned, the minimum term and notice period, and how progress will be reported. Ask what happens to content and links if you leave. Be wary of guaranteed rankings, very low fees for competitive sectors, and link packages priced per link with no editorial standards. A sensible first step for many businesses is a one-off audit, which gives you a prioritised plan you can take to several providers.
Most London SME retainers fall between £1,000 and £5,000 per month. Local campaigns can start at around £500, while competitive national campaigns usually cost £3,000 to £8,000 and enterprise programmes £7,500 or more.
Is SEO More Expensive In London?
Generally, yes. Visionary Marketing’s research found London agencies are typically 15 to 35% more expensive than equivalent regional providers, mainly because of salaries and office costs. Its view is that the quality gap is much smaller than the price gap, so it is worth comparing London and regional quotes.
How Much Does An SEO Audit Cost?
A one-off SEO audit typically costs £500 to £7,500 depending on depth and site size, according to Whitehat. Its own published website audits are £2,500 for an essential audit, £4,500 for a comprehensive one and £7,500 or more for enterprise sites.
How Long Should I Commit To An SEO Retainer?
Most agencies ask for a minimum of three to twelve months, because technical fixes, content and links take time to show results. A six-month initial term with monthly rolling notice afterwards is a reasonable middle ground to negotiate.
Conclusion
SEO in London costs more than in most of the UK, but the range is wide. A local business can get meaningful help for £500 to £1,500 a month, most SMEs spend £1,000 to £5,000, and national and enterprise programmes go well beyond that. Judge each quote by the hours, people and deliverables behind it rather than the headline fee, and start with an audit if you are unsure what your site needs.
