The verdict in three sentences
For a UK insurance mutual with 40,000 to 150,000 members, a website redesign costs 60,000 to 180,000 GBP and takes 5 to 9 months, provided the RFP locks in the quote engine, the member portal connected to the policy administration system, WCAG 2.2 AA accessibility and certified hosting from day one. A vague brief gets paid for later in change requests, which commonly add 20 to 35 % to the initial budget according to digital leads in the sector. Invite 3 to 5 agencies and publish the scoring grid upfront: 40 % technical, 30 % price, 30 % methodology.
The blocks your RFP must price
The classic mistake is describing the future site page by page. For a mutual, the budget is driven by integrations and compliance, not by the number of templates. Each block below must appear with measurable requirements, otherwise agencies will price it their own way and the bids become impossible to compare.
| Block | What the RFP must specify | Share of budget (2026 estimate) |
|---|---|---|
| Health or protection quote engine | Cover levels, age bands, underwriting questions, lead push to the CRM | 10 to 15 % |
| Member portal | Strong authentication, claims tracking, digital membership card, API connector to the policy admin system | 30 to 40 % |
| WCAG 2.2 AA accessibility | Target level, initial and final audit, published accessibility statement | 5 to 8 % |
| Certified hosting | ISO 27001 and Cyber Essentials Plus, UK or EU data residency, disaster recovery, encrypted backups | 5 to 10 % excluding run costs |
| CMS and approval workflow | Editorial workflow with compliance sign-off before publishing | 10 to 15 % |
| Design and UX | Member workshops, usability tests with older users | 15 to 20 % |
| SEO migration | URL inventory, 301 redirect map, structured data | 5 to 8 % |
On accessibility, the Equality Act 2010 requires reasonable adjustments, and the FCA Consumer Duty expects firms to avoid foreseeable harm to vulnerable customers. A large share of members is over 60, and a claims journey that fails with a keyboard or a screen reader turns straight into calls to your contact centre.
Budget, timeline and scoring grid: 2026 benchmarks
The ranges below are 2026 orders of magnitude observed among London and UK agencies working for regional mutuals and friendly societies. They cover design, build and testing, excluding annual running costs.
| Mutual size | Typical scope | Budget | Timeline |
|---|---|---|---|
| 40,000 members | Editorial site, quote engine, read-only member portal | 60,000 to 90,000 GBP | 5 to 6 months |
| 80,000 members | Online claims submission and document upload | 90,000 to 130,000 GBP | 6 to 8 months |
| 150,000 members | Fully online joining with e-signature | 130,000 to 180,000 GBP | 7 to 9 months |
| Annual run | Support, certified hosting, monitoring | 12 to 20 % of build per year | Ongoing |
| External WCAG audit | Initial audit and re-test | 4,000 to 10,000 GBP | 2 to 4 weeks |
On procurement, allow 4 to 6 weeks between sending the RFP and the final decision. Share the scoring grid with the RFP so every agency answers against the same criteria.
| Criterion | Weight | What is scored |
|---|---|---|
| Architecture and systems integration | 20 % | Connector approach, handling of back-office outages, security |
| Accessibility and performance | 10 % | WCAG 2.2 AA commitment, target Core Web Vitals |
| Hosting and compliance | 10 % | Certifications, data residency, exit plan |
| Total 3-year price | 30 % | Build plus run, not build alone |
| Methodology and team | 20 % | Plan, workshops, named people |
| Comparable references | 10 % | Insurance or health projects |
Mini case study
Illustration: Helen, digital lead at an 85,000-member mutual in London, has a budget of 120,000 GBP. Her contact centre handles 9,000 calls a month, 35 % of them about claims status, at an average cost of 5 GBP per call. If the member portal absorbs 40 % of those calls, the saving is 9,000 x 0.35 x 0.40 = 1,260 calls, or 6,300 GBP a month and 75,600 GBP a year. The build pays back in about 19 months, before counting new members generated by the quote engine.

FAQ
Does a mutual need a formal tender process?
Most mutuals are not bound by public procurement rules, but a structured RFP remains standard practice. Send it to 3 to 5 agencies, allow 3 weeks for responses and plan a 90-minute pitch per bidder.
What hosting certifications should we require?
ISO 27001 and Cyber Essentials Plus are the usual baseline, with UK or EU data residency for member data. Expect 500 to 2,000 GBP a month for a managed, monitored setup with a 99.9 % SLA.
How long does the policy admin integration take?
Allow 6 to 12 weeks if the vendor exposes documented APIs. Without APIs, an intermediate file-based flow adds 4 to 6 weeks and 10,000 to 20,000 GBP to the budget.
Can we stay under 70,000 GBP?
Yes, by phasing: editorial site and quote engine first, transactional member portal six months later. The total cost is about 5 to 10 % higher, but cash flow is smoothed.
What support commitment should we ask for?
A 3-year contract with an exit and reversibility clause is common. Require a fix time for blocking defects under 4 business hours.
