Institutional Website RFP Checklist for London Buyers (2026)

The verdict in three sentences

A structured RFP turns a vague tender into an objective comparison: on the same institutional project, quotes move from a 1-to-3 spread to a 1-to-1.4 spread. The 8 key sections — scope, sitemap, CMS, accessibility, SEO, security, SLA, maintenance — must each contain testable criteria, not intentions. Without written acceptance criteria and late penalties, you pay for defects twice.

The 8 sections that compress quote variance

A serious institutional budget in London sits between GBP 60,000 and 180,000 depending on page count, multilingual scope and integrations. The table below breaks down a typical RFP and its budget weight (2026 order of magnitude).

Each line must become a numbered requirement (REQ-01, REQ-02...) with a binary acceptance test: compliant / non-compliant.

Acceptance, deadlines and penalties: the contractual tripod

Acceptance protects the buyer. Define three validation milestones with numeric thresholds, or the final balance keeps getting paid on faith.

A late penalty of 0.5% of the contract value per business day, capped at 10%, is standard and fully negotiable. Add a reversibility clause: content and access exported within 15 days at contract end.

Mini case study

Sarah, communications director of a UK infrastructure group in London, receives four quotes for a corporate rebuild: GBP 65,000, 105,000, 140,000 and 195,000. After imposing the same numbered RFP (32 requirements), the four agencies respond on identical terms: quotes tighten to GBP 98,000, 108,000, 112,000 and 118,000. The spread drops from 200% to 20%. By adding a 0.5%/day penalty and a 10% accessibility retention, she secures roughly GBP 11,000 of guarantee and a real negotiation lever at acceptance.

FAQ

Is an RFP worth it below GBP 80,000?

Yes: even a 6-page document with 20 numbered requirements saves 15-25% by avoiding change orders. Drafting cost (GBP 1,500-4,000) pays back on the first compared quote.

Should I mandate a specific technology?

Specify the need (a CMS with multilingual approval workflow), not the brand. Mandating a tool narrows competition and pushes prices up 10-20%.

How do I cost maintenance in the RFP?

Require a separate monthly retainer covering security, updates and small evolutions: expect GBP 400-1,600/month depending on criticality. Ask for the included hours.

What penalties won't scare off good vendors?

A reasonable penalty (0.5%/day, 10% cap) reassures serious agencies and filters out opportunists. Vendors who reject any penalty often signal delivery risk.

Does UK GDPR apply to a public-facing site?

Yes — the UK GDPR and Data Protection Act apply to any personal data you process. Put a processing register and clear privacy notices in the security section.
