The verdict in three sentences
For an 8-lawyer commercial law firm in London, the three-year total cost of a website sits between 30,000 and 90,000 GBP excluding VAT in 2026, while the build itself is only 14,000 to 28,000 GBP. The item that tips the budget is monthly local SEO (800 to 1,300 GBP per month), followed by maintenance and content updates. Comparing agencies on the build quote alone therefore means comparing 20 to 45 % of the real spend.
The total cost items, one by one
A commercial firm sells expertise and trust: the site must present partners, practice areas (corporate, employment, commercial litigation, cross-border work), insights and a contact form compliant with UK GDPR and legal privilege. In England and Wales, the SRA Transparency Rules add specific obligations: publishing price and service information for certain services (for example employment tribunal claims for employers, debt recovery or licensing), the complaints procedure and the SRA digital badge. Here are the items to include over 36 months.
| Item (2026 order of magnitude, London) | Unit | Range excl. VAT | Over 36 months |
|---|---|---|---|
| Website build (15 to 25 pages) | flat fee | 14,000 to 28,000 GBP | 14,000 to 28,000 GBP |
| Maintenance (updates, security, support) | per month | 120 to 300 GBP | 4,320 to 10,800 GBP |
| Hosting and domain | per month | 40 to 100 GBP | 1,440 to 3,600 GBP |
| Local SEO and content (if chosen) | per month | 800 to 1,300 GBP | 0 to 46,800 GBP |
| Content updates (partners, insights) | per year | 1,500 GBP | 4,500 GBP |
| One-off SEO audit (instead of monthly) | flat fee | 3,000 to 5,000 GBP | 0 to 5,000 GBP |
| SRA price transparency pages | flat fee | 800 to 2,000 GBP | 800 to 2,000 GBP |
The transparency pages are often missing from agency quotes. Ask for them as a separate line, with a yearly review of published prices built into the content budget.
Three 36-month scenarios
| Scenario | Build | Maintenance | Hosting | SEO | Content | 3-year total excl. VAT |
|---|---|---|---|---|---|---|
| Lean | 14,000 GBP | 120 GBP/month, 4,320 GBP | 40 GBP/month, 1,440 GBP | One audit, 4,000 GBP | 4,500 GBP | 28,260 GBP plus 1,500 GBP SRA pages, 29,760 GBP |
| Balanced | 20,000 GBP | 200 GBP/month, 7,200 GBP | 60 GBP/month, 2,160 GBP | 1,000 GBP/month for 18 months, 18,000 GBP | 4,500 GBP | 51,860 GBP |
| Ambitious | 28,000 GBP | 300 GBP/month, 10,800 GBP | 100 GBP/month, 3,600 GBP | 1,200 GBP/month for 36 months, 43,200 GBP | 4,500 GBP | 90,100 GBP |
The lean scenario suits a firm that lives on referrals and networks, the site mainly acting as a business card checked after a first contact. The ambitious scenario makes sense if the firm wants inbound matters on searches such as « corporate lawyer London » or « employment solicitor for employers », where competition is intense and cost per click on Google Ads often exceeds 15 GBP.
How to cut total cost without weakening the site
- Negotiate maintenance over 24 or 36 months: a longer commitment often lowers the rate by 15 to 20 %.
- Time-box monthly SEO: 9 to 18 months of effort is often enough to establish key pages, before moving to a quarterly rhythm.
- Have lawyers write the insights and outsource only editing: an 800-word legal note written in-house beats a generic article.
- Avoid unnecessary paid plugins: 3 or 4 licences at 50 GBP a year add up to over 600 GBP over 3 years.
Mini case study
James, managing partner of an 8-lawyer firm in London (illustrative example), bills on average 9,000 GBP per new business matter. He picks the balanced scenario at 51,860 GBP over 3 years, about 1,440 GBP per month. Six new matters from the website over 36 months, one every 6 months, cover the spend. Assuming 2 qualified enquiries per month and a 15 % conversion rate, he would win about 11 matters over the period, around 99,000 GBP in fees, to be confirmed by tracking form submissions.

FAQ
How much does a law firm website cost over 3 years in London in 2026?
Roughly 30,000 to 90,000 GBP excluding VAT, depending on SEO effort. The build alone is 14,000 to 28,000 GBP.
Do the SRA Transparency Rules apply to my website?
They apply to SRA-regulated firms, which must publish their complaints procedure and display the SRA badge. Price information is required for specific services, so check which of your practice areas are covered.
Is local SEO essential for a commercial firm?
Not if clients come from referrals, yes if you want inbound matters. A budget of 800 to 1,300 GBP per month for 9 to 18 months is a realistic starting point in London.
What does maintenance at 120 or 300 GBP per month cover?
At 120 GBP, security updates and backups. At 300 GBP, add monitoring, a 4 working hour response time and 1 to 2 hours of changes per month.
Does the website need special hosting for confidentiality?
The site should never store case documents. For the contact form, UK or EU hosting at 40 to 100 GBP per month with encrypted submissions is enough.
