What TfL Bids Are Like

Transport sector procurement runs at large scale — rail and roads programmes, infrastructure delivery, rolling stock, and operational services. Bidders need engineering credentials, asset management capability, and clear safety governance.

Evaluation Criteria You'll Face

  • Engineering and technical capability
  • Asset management and safety governance
  • Programme delivery track record
  • Sustainability and net-zero
  • Social value and skills development
  • Whole-life cost

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 TfL

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 TfL 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
