What CCS Bids Are Like
Central government procurement under the Procurement Act 2023 is increasingly framework-driven via Crown Commercial Service. Quality typically counts for 60–70% of evaluation, with strong emphasis on social value, accessibility, and value for money.
Evaluation Criteria You'll Face
- Quality of approach (typically 60-70% weighting)
- Social value (PPN 06/20, 10% minimum)
- Accessibility (WCAG 2.1 AA)
- Carbon reduction plan (PPN 06/21 for £5M+)
- Experience delivering similar contracts
- Price and value for money
Quality typically weighs 60–80% with price at 20–40%. Bids that score well are specific, evidence-based, and quantified. Generic capability statements rarely win.
How to Write a Winning Bid for CCS
The mechanics of writing a winning UK public sector bid are well-defined. The hard part is doing them under deadline pressure across multiple bids in parallel. The strongest playbook for SMEs and lean teams is:
- Use a structured bid/no-bid framework before committing to write — not every CCS opportunity is right for you
- Read the specification and evaluation criteria carefully — see our guide to writing a winning UK government bid
- Build a bid library of past responses and evidence so each new bid compounds
- Use AI bid writing software like BidWriter to generate structured first drafts grounded in your library — saving 60–80% of writing time
- Run your draft through an evaluator before submission — see our 15 bid writing tips
