The verdict in three sentences
Redesigning an accounting firm website in London costs, in 2026, between 9,000 and 20,000 EUR excl. VAT, depending on page count and whether you add a fee estimator and connected online booking. Budget 7 to 11 weeks of production and GDPR-compliant EU/UK hosting from launch. The real ROI comes from two features: the estimator (+20 to 35 % enquiries) and the careers area, which solves the sector's number-one problem — recruiting staff.
What a redesign costs in 2026
Budget depends mostly on conversion features, not page count. Here are 2026 orders of magnitude for a 3-to-20-person firm.
| Scope | Pages / features | Price EUR excl. VAT | Timeline |
|---|---|---|---|
| Essential brochure | 6-8 pages, blog, contact | 9,000 - 12,000 | 7-8 wks |
| Brochure + conversion | + fee estimator + booking | 13,000 - 16,000 | 8-10 wks |
| Full firm | + careers area + light client portal | 16,000 - 20,000 | 9-11 wks |
| Multilingual option | +1 language | +2,500 - 4,000 | +2 wks |
| SEO copywriting (10 pages) | optimised content | +2,000 - 3,500 | included |
Recurring costs and compliance
The site is an asset: budget maintenance, compliant hosting and SEO. Accounting client data is sensitive, so hosting must stay in the EU/UK.
| Item | 2026 range | Detail |
|---|---|---|
| Maintenance | 150 - 300 EUR/month | updates, security, fixes |
| GDPR EU/UK hosting | 30 - 80 EUR/month | server, backups, SSL |
| Monthly local SEO | 400 - 900 EUR/month | "accountant + city" |
| Estimator (SaaS option) | 0 - 50 EUR/month | if external module |
| Domain name | 15 - 40 EUR/year | .co.uk or .com |
Local SEO typically doubles visibility on queries like "accountant central London" or "startup accounting firm", where acquisition is won.

Mini case study
Nadia, partner in a 12-person firm in the City of London. She receives 18 qualified enquiries a month via her old site. After a redesign (budget 15,500 EUR excl. VAT) with a fee estimator, enquiries rise to 24 a month (+33 %). Converting 20 % into engagements worth 3,200 EUR average annual billing, the 6 extra enquiries generate roughly 46,000 EUR of recurring revenue. The site pays for itself in under 5 months, before counting the recruitment gain.
FAQ
Exactly how much is a fee estimator? On its own, 2,500 to 5,000 EUR excl. VAT depending on rule complexity (packages, VAT, options). Bundled into the redesign, economies of scale often bring it to 2,000 - 3,500 EUR.
Is a client portal essential? Not for the brochure site, but a light portal (secure document upload) cuts email exchanges by 30 to 40 % and builds loyalty. Budget 3,000 to 6,000 EUR excl. VAT extra.
What is a realistic timeline for a full redesign? 7 to 11 weeks: 2 weeks scoping and design, 4 to 6 development, 1 to 2 content and QA. Late content is the top cause of delay.
Must the site be hosted domestically? EU/UK hosting is enough for GDPR compliance. Local hosting is a sales argument, not a legal requirement.
How do I measure ROI? Track qualified enquiries, conversion to engagement and acquisition cost. A simple dashboard (form + booking + estimator) works from month one.
