Summary of the contracting process

The "Portcullis House Lifecycle Replacement Project", spearheaded by the House of Commons in London, falls under the building installation work category. This procurement process, currently in the award stage, commenced on 3rd December 2025. It involves a two-stage contract with Early Contractor Involvement for the replacement of mechanical, electrical, and plumbing systems. The project’s estimated value ranges from £40 million to £50 million, and the completion of Stage 1 will determine the full value of Stage 2. The project's contract period spans from 8th December 2025 to 27th June 2029, with a procurement method of 'selective', calling off from a framework agreement. The award was granted to Willmott Dixon Construction Limited.

This tender presents a substantial growth opportunity for large construction companies adept in complex building installation projects, particularly those with a track record in government contracts and MEP system upgrades. Although the opportunity is not exclusively geared towards SMEs or VCSEs, it could promote collaborative ventures or joint bids, leveraging the expertise of various stakeholders to fulfil extensive and technical requirements. Businesses with a significant presence in the United Kingdom or established connections within the London region might find strategic value in engaging with such high-value government projects.
