What Sellafield Bids Are Like
Public body procurement varies in style but typically follows UK procurement regulations with quality-weighted scoring, social value requirements, and a structured evaluation framework.
Evaluation Criteria You'll Face
- Quality of approach
- Experience delivering similar work
- Social value
- Methodology and delivery plan
- 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 Sellafield
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 Sellafield 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
