## Summary

Gov Facility Services Ltd procured construction and mechanical engineering works for HMP The Verne in Dorset. The requirement covered the main boiler house and the existing district main heating circuit. The works included installing a new inline mechanical filtration system with heat exchangers and replacing four existing main boilers. This is a heating infrastructure upgrade rather than routine maintenance or supply-only work, requiring coordinated work on live or established building-services systems. The main category is construction work. The buyer is a central-government facilities organisation responsible for public-sector estate services, and the delivery site is the prison’s main boiler house at HMP The Verne. The requirement would suit contractors able to undertake industrial or commercial boiler replacement, district heating modifications, mechanical filtration installation and associated construction works in a secure operational environment.

The procurement is complete and has been awarded following a below-threshold limited competition. One lot was awarded to iDCC SERVICES LTD, an SME. The award was made on 17 September 2026 and the contract was signed the same day. The contract runs from 18 September 2026 to 20 May 2027. Its value is £973,584.28 excluding VAT and £1,168,301.14 including VAT. The evaluation basis is reflected in the limited competition route, with the detailed award criteria set out through the procurement process. The awarded scope is construction work covering the filtration system, heat exchangers and replacement of four main boilers at HMP The Verne. The contract is active, while the associated tender is complete, so this particular requirement has already reached its outcome.

This award is useful market evidence for mechanical and building-services contractors targeting Gov Facility Services Ltd. It demonstrates demand for substantial boiler-house replacement and district-heating improvement works within the public-sector custodial estate, delivered as a single construction lot through a below-threshold limited competition. A credible competitor for a future requirement would need practical capability in replacing multiple commercial or industrial boilers, integrating heat exchangers into an existing heating circuit, installing inline mechanical filtration and coordinating associated construction activities. Experience working around operational public buildings, managing interfaces with existing plant and maintaining safe delivery in a secure prison environment would strengthen a supplier’s position. The successful supplier was an SME, indicating that this type of requirement can be delivered by a suitably capable specialist contractor without necessarily being limited to major national construction groups.
