## Summary

Sellafield Ltd procured contractor compliance auditing services for the 2026–2028 period. The work covers auditing contractors to assess compliance, supporting the buyer’s assurance and governance requirements. It is a services contract within the auditing services category (CPV 79212000), delivered in the North West of England, including the CA20 1PG area. The published scope identifies Sellafield Ltd as the buying organisation. The opportunity was considered suitable for small and medium-sized enterprises, so it is relevant to specialist audit firms and other smaller providers with the skills and operating capacity to undertake contractor compliance reviews in this area.

The procurement is complete and was awarded through the Business & Technical Services Marketplace Dynamic Purchasing System. The tender submission deadline was 22 April 2026 at 12:00. The contract was awarded to Baker Mallett LLP on 22 July 2026, with an awarded value of £310,239.55. The contract period runs from 1 August 2026 to 30 June 2028. The procurement’s stated estimated value range was £310,239 to £651,503.03. One supplier is identified for the award. The contracting route was a dynamic purchasing system marketplace, rather than a standalone open tender, and the requirement was classified as services.

This award demonstrates established demand from Sellafield Ltd for specialist contractor compliance auditing in the North West. Suppliers considering comparable future work would need credible audit and compliance-assurance capability, with the professional judgement to examine contractor performance against applicable requirements and produce clear, defensible findings. They would also need sufficient delivery capacity for a substantial, multi-year programme and the ability to work effectively in the relevant local area. The buyer’s identification of the requirement as suitable for SMEs indicates that specialist smaller firms can be credible competitors where they can evidence relevant auditing experience, robust quality controls, competent staff and the organisational resilience to maintain consistent service across the contract.
