The verdict in three sentences
For a health mutual in London with 45,000 members, a serious corporate website costs GBP 45,000 to 80,000 (about EUR 52,000 to 93,000) and takes 12 weeks, with the member portal pushed to phase 2. The module that makes the difference is the provider network finder: it is the most visited page and the one that cuts calls to the contact centre the most. UK GDPR compliance and WCAG 2.2 AA accessibility are not optional: both belong in the brief from day one.
What the website must do for a health mutual in 2026
Members do not visit a mutual's website to read the chair's statement. They want to know which physiotherapist or private clinic accepts their plan in Croydon, what their cover includes and how to start a claim. The board wants a site that reassures employer clients, partners and the regulators.
The dominant technical constraint is the device: roughly 60% of traffic comes from mobile, much of it older Android handsets used by members on lower-cost plans. Each page should stay under 1.2 MB and render in under 3 seconds on a 4G connection.
| Module | Phase | Indicative 2026 budget | Expected impact |
|---|---|---|---|
| Corporate pages (governance, reports, news) | 1 | GBP 7,000 to 11,000 | Credibility with employers and partners |
| Geolocated provider network finder | 1 | GBP 11,000 to 18,000 | 25 to 35% fewer "where can I go" calls |
| Plans and cover pages by profile | 1 | GBP 6,000 to 9,000 | Clear comparison for employer clients |
| Employer enquiry form + CRM routing | 1 | GBP 4,500 to 8,000 | Qualified B2B leads |
| UK GDPR compliance and consent management | 1 | GBP 4,000 to 6,500 | ICO-ready documentation, lower legal risk |
| WCAG 2.2 AA audit and fixes | 1 | GBP 5,000 to 9,000 | Access for older and visually impaired members |
| Member portal (claims, digital card) | 2 | GBP 30,000 to 55,000 | Outside phase 1, quoted separately |
Phase 1 therefore lands between GBP 45,000 and 80,000, depending on the number of providers to import and the depth of integration with the existing policy administration system.
Compliance, accessibility and performance: the requirements that move the quote
Under UK GDPR, health data is special category data. Even without a member portal, the enquiry form collects sensitive information: encryption, access logging, a documented hosting setup and a data protection impact assessment are expected. If the mutual is authorised by the PRA and FCA, financial promotion rules also apply to plan pages.
| Requirement | Minimum level | Recommended level | Estimated extra cost |
|---|---|---|---|
| Personal data (UK GDPR) | Privacy notice, cookie banner | Record of processing, DPIA, encrypted forms | GBP 4,000 to 6,500 |
| Accessibility | Contrast, alt text | Full WCAG 2.2 AA audit, keyboard navigation, screen reader tests | GBP 5,000 to 9,000 |
| Mobile performance | Compressed images | Pages under 1.2 MB, server rendering, CDN cache | Included if planned at design stage |
| Security | HTTPS | CSP headers, bot protection, daily backups | GBP 2,000 to 3,500 |
| Hosting and monitoring | Shared | Cloud with CDN, 99.9% uptime | GBP 300 to 700 per month |
| Financial promotions review | None | FCA-aligned review of plan pages | GBP 1,500 to 3,000 |
Typical 12-week plan: weeks 1 and 2 discovery and provider inventory, weeks 3 to 5 design and board sign-off, weeks 6 to 10 build and network import, weeks 11 and 12 accessibility audit, user acceptance testing and launch.
Mini case study
Helen, chief executive of a health mutual in London, receives about 9,000 calls a month, 30% of them asking where to find an approved provider. She invests GBP 62,000 in the phase 1 website. With the provider finder, the estimate is 2,000 fewer calls a month. At GBP 6 for the full cost of a handled call (agent time, telephony), the saving reaches GBP 12,000 a month. The website pays back in just over 5 months, before counting the new employer clients captured through the enquiry form.

FAQ
Should the member portal launch in phase 1?
In most cases, no. The portal adds GBP 30,000 to 55,000 and depends on the integration with your policy system, which extends the project by 8 to 10 weeks.
How do we keep the provider network up to date?
The most reliable option is a weekly automatic import from your provider contracts database. Otherwise, a simple back office lets one person update 50 to 100 listings in an hour.
Do we need a DPIA for a corporate website?
Yes as soon as a form collects health-related data. Allow 2 to 4 weeks to complete it with your DPO, so start in week 2 of the project.
Why WCAG 2.2 AA rather than level A?
A significant share of your members are over 55 or have a visual impairment. Level AA covers contrast and text size, which also improves small-screen reading for 100% of visitors.
What annual budget should we plan after launch?
Count GBP 800 to 1,500 a month for maintenance plus GBP 300 to 700 for hosting, so roughly GBP 13,000 to 26,000 a year.
