RFP writing is the process of crafting a compelling, evidence-based proposal in response to a buyer's Request for Proposal.
The difference between winning and losing is rarely about capability — it's about how clearly you communicate your capability in writing.
The average UK RFP win rate stands at 46%, but top-performing teams consistently achieve 60% or higher (Loopio 2025 RFP Trends Report).
The gap between average and excellent is almost entirely down to writing quality.
The RFP Writing Process: 6 Steps
Step 1: Decode the Evaluation Criteria
Before writing a word, understand how your response will be scored.
Every RFP has evaluation criteria — usually quality (60–70%), price (20–30%), and social value (10%+).
Map each scored question to its weighting.
This determines where to invest your best writing effort.
Step 2: Run a Bid/No-Bid Decision
Not every RFP is worth responding to.
With the average response taking 25 hours (Bidara, 2025), investing in the wrong opportunity has real cost.
Evaluate: Do you meet the mandatory requirements? Is the contract value worth the response investment? Do you have relevant experience? Can you deliver? If any answer is no, walk away and focus on opportunities you can win.
Step 3: Build Your Response Structure
Mirror the buyer's document structure exactly.
If they ask 10 questions, answer 10 questions in the same order.
Never reorganise to suit your preferred format.
Use the buyer's terminology, not yours.
If they say "service users" don't write "customers".
If they say "programme" don't write "project".
Step 4: Draft With Evidence
Every claim needs proof. "We have extensive experience" scores zero. "We delivered a £2.3M cleaning contract for Yorkshire NHS Trust in 2024, achieving 98% KPI compliance across 14 sites" scores maximum.
Use specific numbers, named clients (with permission), and measurable outcomes.
Tools like rfp.quest maintain a content library of approved case studies and evidence statements.
Step 5: Score Your Own Response
Before submitting, score your draft against the published evaluation criteria.
Be honest.
If a section would score 3/5, rewrite it until it scores 5/5.
This self-assessment step is the single highest-impact quality improvement you can make.
Step 6: Review, Polish, Submit
Have someone who didn't write the response read it.
Fresh eyes catch assumptions, jargon, and gaps.
Check word counts, formatting requirements, mandatory attachments, and submission method.
Late or non-compliant submissions are almost always rejected regardless of quality.
What Evaluators Actually Look For
Having reviewed hundreds of RFP responses, evaluators consistently reward:
| What scores high | What scores low |
|---|---|
| Specific evidence with metrics | Generic claims without proof |
| Understanding of the buyer's context | One-size-fits-all responses |
| Named team members with relevant CVs | "Our team of experts" |
| Realistic methodology with milestones | Vague approach descriptions |
| Risk identification and mitigation | No mention of risks |
| Innovation tailored to the brief | Innovation for its own sake |
| Social value commitments with targets | Boilerplate CSR statements |
RFP Writing vs Tender Writing: Is There a Difference?
In practice, very little.
The skills are identical:
-
Understand the evaluation model
-
Structure your response to score against criteria
-
Provide evidence for every claim
-
Write clearly and concisely
The main difference is context: "RFP writing" tends to refer to private sector proposals, while "tender writing" refers to UK public sector responses governed by the Procurement Act 2023.
The writing discipline is the same.

RFP Writing Services vs RFP Writing Software
| RFP Writing Services | RFP Writing Software | |
|---|---|---|
| Cost | £2,000–£10,000+ per response | £99–£299/month unlimited |
| Speed | 1–2 weeks per response | Same day with AI assistance |
| Knowledge retention | Walks out the door with the consultant | Stays in your content library |
| Scalability | Linear cost increase | Fixed cost regardless of volume |
| Quality | High (if you find a good writer) | Consistent (AI + your expertise) |
| Best for | One-off high-value bids | Ongoing RFP response programmes |
For most UK businesses responding to more than 3 RFPs per year, RFP software is more cost-effective than outsourced writing services.
The software handles structure, compliance, and first-draft generation; your team provides the sector expertise and evidence.
Common RFP Writing Mistakes
- Starting with your company history — Evaluators don't care about your founding story.
Start with how you'll solve their problem.
- Exceeding word counts — If the limit is 1,000 words, submit 1,000 words.
Going over signals you can't follow instructions.
- Recycling old responses — Evaluators can tell.
Tailor every response to the specific buyer and requirement.
- Ignoring social value — In UK public procurement, social value is typically 10%+ of the score.
That's often the difference between winning and losing.
- Submitting without proofreading — Typos, formatting errors, and missing sections signal carelessness.
If you can't get the bid right, can you get the contract right?
UK Context: Writing for the Procurement Act 2023
The Procurement Act 2023 came into full effect on 24 February 2025.
For RFP writers, the key changes are:
-
Open tendering increased from 27% to 41% of all UK procedures (Open Contracting Partnership) — more opportunities published openly
-
72% of lots now SME-suitable — smaller businesses can compete more broadly
-
Competitive Flexible Procedure — allows negotiation rounds, making RFP-style writing skills more valuable in public sector
-
Social value mandatory — every response needs a credible social value section
-
All above-threshold contracts published on Find a Tender
Frequently Asked Questions
How long does it take to write an RFP response? The average is 25 hours, down from 30 hours in 2024 (Loopio, 2025).
With AI-assisted tools like rfp.quest, teams report completing responses in 10–15 hours.
What is the average RFP win rate? The UK average is 46% (Bidara, 2025).
Top-performing teams achieve 60%+.
The main differentiator is response quality, not capability.
Should I hire an RFP writing service or use software? For one-off high-value bids (£500K+), a specialist writer can be worth the investment.
For ongoing response programmes (3+ RFPs per year), software is more cost-effective and builds institutional knowledge.
What qualifications do RFP writers need? No formal qualifications are required, but CIPS (Chartered Institute of Procurement & Supply) certification demonstrates procurement knowledge.
The most important skill is the ability to write clearly, concisely, and with evidence.
How do I improve my RFP win rate? Three highest-impact actions: (1) Only bid on opportunities you can genuinely win, (2) Score your own response before submitting, (3) Use a content library of approved evidence statements.
