## Summary

Sellafield Limited procured concrete blocks and assemblies to frame existing Zapp shelters at the Sellafield waste processing facility. The supply includes interlocking concrete block bays, 2.4 metres high, for existing shelters in several configurations, with spreader and flat-top blocks and galvanised valley gutters and outlets. It also covers a new 12-metre-wide shelter, mounting brackets and fixings, partial end walls, anchor assemblies and conversion kits for existing 10- and 12-metre shelters, including off-site welding. The requirement is for goods and associated delivery, supporting the use of containerised shelter units already procured to bespoke dimensions. Delivery is in the United Kingdom; the facility is at Sellafield.

The procurement is complete and was awarded to Paragon Protection Systems Ltd. The award date was 15 October 2026, and the contract period runs from 30 October 2026 to 31 March 2027. The awarded value is £558,582 excluding VAT (£670,298.40 including VAT). It was a direct award, justified by the need for compatibility with bespoke existing shelters and to avoid design changes, maintenance complexity, cost, schedule and technical risks; the buyer considered competition inappropriate. The requirement was structured as one lot, suitable for small and medium-sized enterprises. The published outcome records the award as pending, with contract signature scheduled for 28 October 2026.

This award shows demand at Sellafield for engineered concrete bay assemblies and shelter mounting components that fit existing, bespoke Zapp shelter installations. A credible supplier for a comparable requirement would need to supply interlocking concrete blocks in the required configurations, accurately matched brackets, anchors, fixings and conversion kits, and galvanised drainage components. The work also calls for delivery coordination and off-site welding capability. Relevant experience would include designing or supplying components to established dimensions and specifications, and demonstrating that replacements or additions can be integrated without compromising compatibility, standardisation or maintainability of existing assets. The direct award rationale makes technical fit with the installed shelters central to the buyer’s decision; suppliers with evidence of equivalent system knowledge and reliable production across multiple shelter configurations would be best placed to compete if this requirement returns to market.

### Procurement Information

The blocks are required for existing containerised tents that have already been procured to bespoke dimensions and specifications. Procuring from an alternative supplier could introduce compatibility issues, require design modifications, and increase maintenance complexity. This would create unnecessary cost, schedule, and technical risks while potentially impacting the performance and standardisation of the existing assets. Therefore, competition is not considered appropriate in this instance. This procurement is in accordance with PA23, Schedule 5, Paragraph 6.
