An RFP (Request for Proposal) is one of the most important instruments in the procurement cycle. It bridges the gap between market engagement and contract award, giving buyers a structured way to evaluate competing solutions on quality, approach, and price. In 2026, UK public procurement represents roughly one-third of £1,335 billion total public expenditure (Hermix, 2025), and understanding how RFPs fit into this landscape is essential for any supplier or buyer.
Where RFPs Fit in the Procurement Cycle
Procurement follows a structured cycle. The RFP sits at the evaluation stage — after planning and before contract award:
1. Identify Need
The organisation recognises a requirement that cannot be met internally. This triggers the procurement process.
2. Market Engagement (RFI)
Before defining requirements, smart procurement teams consult the market. A Request for Information gathers intelligence on available solutions, typical costs, and capable suppliers. The Procurement Act 2023 formally encourages this step.
3. Specification Development
Using RFI responses and internal analysis, the procurement team writes a detailed specification. This defines what the organisation needs — the foundation of the RFP.
4. RFP Issuance
The formal Request for Proposal is published, inviting suppliers to submit detailed proposals. In UK public sector, contracts above £135,018 (central government) or £207,720 (sub-central) must be published on Find a Tender.
5. Evaluation
Responses are scored against published criteria. The average UK RFP win rate is 46% (Bidara, 2025). Evaluation panels score independently, then moderate to reach consensus.
6. Contract Award
The winning supplier is notified. In UK public sector, a 10-day standstill period applies before the contract is signed, allowing unsuccessful bidders to challenge the decision.
RFP Procurement in the UK Public Sector
UK public procurement is governed by the Procurement Act 2023, which came into full effect on 24 February 2025. The Act replaced the EU-derived Public Contracts Regulations 2015 and introduced significant changes for both buyers and suppliers.
Key changes under the Act:
- Open tendering increased from 27% to 41% of all UK procedures between March 2025 and February 2026 (Open Contracting Partnership)
- Direct awards decreased from 53% to 34% — more contracts are competitively tendered
- 72% of lots now SME-suitable — the highest proportion on record
- Competitive Flexible Procedure — allows buyers to design bespoke procurement approaches combining elements of open, restricted, and negotiated procedures
- Transparency requirements — all above-threshold contracts on Find a Tender, below-threshold on Contracts Finder
Procurement thresholds (2025–2026):
| Category | Threshold | Publication | |----------|-----------|-------------| | Central government goods/services | £135,018 | Find a Tender | | Sub-central goods/services | £207,720 | Find a Tender | | Works (all) | £5,372,609 | Find a Tender | | Below threshold (central) | £12,000+ | Contracts Finder | | Below threshold (other) | £30,000+ | Contracts Finder |
RFP Procurement in the Private Sector
Private sector RFP procurement is not governed by legislation but follows similar principles for governance, value for money, and risk management. Key differences from public sector:
- No publication requirements — RFPs can be sent to selected suppliers only
- Flexible evaluation — criteria and weightings can be adjusted during the process
- Negotiation is standard — post-submission discussions are expected
- Speed — no statutory minimum timescales
- Relationship factors — incumbent advantage is real and acknowledged
Large corporates, financial institutions, and regulated industries often adopt public sector-style rigour voluntarily. CIPS (Chartered Institute of Procurement & Supply) provides professional standards used across both sectors.
The Economics of RFP Procurement
Procurement is expensive for both buyers and suppliers:
| Metric | Value | Source | |--------|-------|--------| | Average RFP response time | 25 hours | Loopio, 2025 | | Average UK win rate | 46% | Bidara, 2025 | | Top-team win rate | 60%+ | Loopio, 2025 | | Teams completing in <10 days | 64% | Loopio, 2025 | | Planning to submit more RFPs | 61% | Loopio, 2025 | | UK public procurement value | ~£445 billion | Hermix, 2025 |
For suppliers, every unsuccessful RFP response costs approximately £1,250 in staff time (25 hours at £50/hour). With a 46% win rate, the average cost to win one contract through RFP is approximately £2,700 in response effort. This makes bid/no-bid discipline and response quality the two biggest levers for procurement ROI.
Tools like rfp.quest reduce response time through AI-assisted drafting and reusable content libraries, improving both the cost and quality equations.
Best Practices for RFP Procurement
For Buyers:
- Engage the market early — Use RFIs before writing specifications
- Publish evaluation criteria clearly — Suppliers can only score against what they can see
- Allow adequate response time — Complex RFPs need 4–6 weeks minimum
- Provide feedback to unsuccessful bidders — Improves future response quality
- Consider SME access — 72% of UK lots are now SME-suitable; ensure your process doesn't inadvertently exclude smaller businesses
For Suppliers:
- Be selective — Only respond to RFPs you can genuinely win
- Decode the evaluation model — Understand exactly how you'll be scored
- Lead with evidence — Every claim needs proof. See our RFP writing guide
- Address social value — 10%+ of UK public sector scoring
- Use technology — RFP software cuts response time and improves consistency
Frequently Asked Questions
What does RFP mean in procurement? RFP stands for Request for Proposal. In procurement, it is a formal document inviting suppliers to submit detailed proposals for evaluation. See our full guide on what RFP means.
What is the RFP procurement process? The process follows: need identification → market engagement (RFI) → specification → RFP issuance → evaluation → contract award. In UK public sector, statutory procedures under the Procurement Act 2023 apply.
How does UK public procurement work? All contracts above threshold must be published on Find a Tender. Suppliers submit responses scored against published criteria. A 10-day standstill period follows before contract signature.
What is the difference between an RFP and an RFQ in procurement? An RFP evaluates complete proposals (quality, approach, team, price). An RFQ focuses primarily on price for a fully defined specification.
How much does UK public procurement spend each year? UK public procurement represents roughly one-third of £1,335 billion total public expenditure — approximately £445 billion annually (Hermix, 2025).
