Can I win this?

Competition

Typical: a median of 4 bids per contract for waste contracts across the UK (from 484 awards in the last 12 months).

Framework

Winning puts you on a list of suppliers the buyer can call on; it does not guarantee work. The £23,000,000 is the most the buyer expects to spend across all suppliers over the framework's life, not one contract.
