Tender Notice
Summary of the contracting process

UK Atomic Energy Authority is procuring civil, mechanical and electrical installation works for the DBB Blockhouse low-voltage distribution system. The work covers installation from the existing D12 Automatic Transfer Switch to D1-PDU12, including associated isolation transformers and an auxiliary distribution board. The scope includes handling and installing equipment, civil works, cable containment and cable installation, glanding and termination, earthing and bonding, inspection and dead testing, plus support during UKAEA-controlled energisation. This is low-voltage installation work (CPV 45315600), with related electrical engineering, cable-laying and electrical distribution apparatus installation. The procurement is categorised as works, with delivery listed in the United Kingdom.

The procurement reached tender: the buyer invited offers through an open procedure. The tender was published on 7 September 2026, and the submission deadline set by the buyer is 23 September 2026 at 12:00 BST. The planned contract period runs from 7 October 2026 to 31 December 2026. The estimated contract value is £100,000. The tender concerns a single defined work package rather than separately described lots. Offers are sought for the complete installation scope, including the works needed to prepare the system for UKAEA-controlled energisation. The opportunity is identified as suitable for small and medium-sized enterprises and voluntary, community or social enterprises.

This opportunity suits electrical installation contractors able to deliver integrated low-voltage distribution works, rather than suppliers providing equipment alone. Relevant capability includes electrical engineering, cable containment and laying, glanding and termination, installation of distribution apparatus and isolation transformers, earthing and bonding, and associated civil and mechanical works. Suppliers will need to handle site equipment safely, inspect completed installations and carry out dead testing before supporting a controlled energisation led by UKAEA. It is suitable for SMEs and VCSEs, so smaller specialist contractors with the necessary technical team, installation resources and capacity to complete a defined work package may be well placed to compete. Experience coordinating multiple disciplines on an electrical infrastructure installation would be particularly relevant.
