How Bidwell helps
Win more of the Sellafield Ltd pipeline
SMB share at Sellafield Ltd is 3.6%, well under the public-sector benchmark. If you are a smaller supplier, you are statistically under-represented in this pipeline, and Bidwell is built to change that. We watch every notice the buyer publishes, score it against your past wins, and draft a complete first response in around 30 minutes so you can bid on the awkward ones you would normally skip.
