The verdict in three sentences
A premium showcase website for a business law firm in London runs between 10,000 and 20,000 EUR ex VAT in 2026, plus 4,000 to 8,000 EUR for a publications CMS with newsletter. The sector specifics, confidentiality by design, and data-protection compliance (UK GDPR) are built in rather than optional. With a capable team, the firm gets a credible, compliant site in 5 to 8 weeks.
The detailed figures (2026, EUR ex VAT)
For a business law firm the site is a reputation and business-development tool: it must present practice areas, showcase expertise through publications and reassure on confidentiality. Here is the grid.
| Item | Scope | Price EUR |
|---|---|---|
| Premium showcase | 8-12 pages, practice areas, team, restrained design | 10,000 - 20,000 |
| Publications CMS + newsletter | Articles, legal alerts, subscription | +4,000 - 8,000 |
| Additional language | Second version, localisation | +2,500 - 5,000 |
| GDPR compliance | Notices, consent, records, security | included |
| EU/UK secure hosting | SSL, CSP headers, backups | 40 - 90 EUR/month |
| Maintenance | Upkeep + publications | 150 - 400 EUR/month |
Terms: 40% upfront, 30% at design acceptance, 30% on delivery. GDPR compliance is built in, not a surcharge.
Confidentiality and compliance: what it involves
A business law firm handles sensitive information; its site must reflect that from the design stage. The concrete 2026 requirements:
| Requirement | Implementation | Impact |
|---|---|---|
| UK GDPR (personal data) | Records, consent, DPO notices | included |
| Secure forms | Encryption, anti-spam, limited retention | included |
| Security headers | CSP, HSTS, XSS protection | +500 - 1,200 |
| Second language | Regional credibility | +2,500 - 5,000 |
| Controlled hosting | EU/UK certified datacentre | 40 - 90/month |
These are not cosmetic: they protect the firm's reputation and the client relationship.
Mini case study
Mr Whitfield, managing partner of a 12-lawyer business law firm in London, launches his site. He chooses the premium showcase + publications CMS + second language: 14,000 + 6,000 + 3,500 = 23,500 EUR, plus maintenance 300 EUR/month and hosting 70 EUR/month. Year-1 cost: 23,500 + (12 x 370) = 27,940 EUR. Previously, legal alerts went out via manual emails, about 4 h/month of assistant time. The CMS + newsletter automate that (~48 h/year saved) and, crucially, position the firm on business-law queries; a single M&A or commercial-litigation matter captured through the site repays the annual investment several times over.

FAQ
Is GDPR compliance really included?
Yes: processing records, legal notices, consent banner and form security are part of the base, not a hidden surcharge.
Why a publications CMS?
Because legal alerts and articles are the main credibility and SEO lever for a firm. Budget +4,000 to 8,000 EUR for editorial autonomy.
Is a second language necessary?
For a firm serving international clients, a second version widens the audience for +2,500 to 5,000 EUR.
How is contact confidentiality guaranteed?
Encrypted forms, limited data retention, security headers (CSP, HSTS) and controlled hosting; all sized from the design stage.
What timeline should I plan?
5 to 8 weeks depending on scope, the bottleneck usually being partner sign-off on content.
