UK3 - Planned Procurement Notice
Summary of the contracting process

The Department for Transport is procuring works to replace and upgrade the gas burner systems serving three boilers at the IMO Building, 4 Albert Embankment, London. The contractor will remove and dispose of existing Ecoflam burners and redundant equipment, install new low-NOx gas burners, burner plates and associated components, and replace boiler-door refractory and water-temperature sensors. The work also includes modifying gas pipework, gas trains, electrical supplies, control wiring and burner enable circuits, while integrating existing boiler flow switches. The contractor must carry out gas-tightness testing, combustion analysis, safety-device testing and manufacturer-approved commissioning. The scope includes testing, commissioning and compliance documentation, removal of redundant materials and associated builders’ works. The works are to be undertaken sequentially so that at least two boilers remain operational throughout, maintaining heating resilience.

The procurement has reached tender: the buyer has invited offers through a below-threshold open competition, with tender documents and returns managed electronically through Jaggaer. Questions and clarification requests had to be submitted by 31 July 2026 at 23:59, and tender responses were due by 7 August 2026 at 12:00. The single lot has an estimated value of £100,000 excluding VAT, or £120,000 including VAT. The contract period is 5 to 12 October 2026. Tenders will be assessed against three technical questions and one social value question; submissions meeting the scoring threshold will proceed to commercial assessment. The authority reserves options to amend the final requirement, scope and associated costs as further information becomes available.

This opportunity suits specialist boiler, heating and mechanical engineering contractors able to replace commercial gas burners and work on multiple-boiler installations. Suppliers should be capable of supplying and installing low-NOx burners, burner plates, refractory components, water-temperature sensors and associated gas, electrical and control-system modifications. Relevant expertise includes gas pipework and gas-train work, combustion analysis, gas-tightness testing, safety-device testing, boiler controls and manufacturer-approved commissioning. The requirement also calls for disciplined sequencing in an occupied or operational building, keeping two boilers running while each installation is completed, together with builders’ works, removal of redundant equipment and comprehensive compliance records. Businesses should be able to coordinate site activities, demonstrate sound technical delivery and address technical and social value requirements in their tender response.
