UK3 - Planned Procurement Notice
Summary of the contracting process

UK Fusion Energy Ltd intends to commission a concept-level heating, ventilation and air-conditioning study for the Spherical Tokamak for Energy Production (STEP) prototype fusion facility. The work will cover the facility’s maintenance, handling and supporting infrastructure, establishing the technical basis for its HVAC architecture and ventilation strategy. Outputs will inform the Tokamak Building layout, contamination-control strategy, nuclear ventilation philosophy and a rough-order-of-magnitude cost estimate for HVAC plant and associated systems. This is a specialist engineering and feasibility service, including building heating engineering, mechanical and electrical installation design, ventilation consultancy and analysis. Delivery is for the STEP development in the United Kingdom, with the buyer based at Culham Science Centre, Abingdon.

This is a planned procurement: the buyer has stated its intention to run a below-threshold open competition, but this notice is not an invitation to quote or tender. The anticipated value is £70,000 excluding VAT (£84,000 including VAT). The buyer expects the next notice to be published on 26 August 2026. Indicative contract delivery is from 24 September to 14 December 2026, with one optional one-month extension available to 14 January 2027. The procurement is a single planned lot and is expected to be suitable for SMEs. Quality is listed as the primary evaluation criterion, followed by price. Suppliers interested in preparing for the competition may register their interest through the UK Fusion Energy e-sourcing portal.

The requirement should suit an HVAC engineering consultancy or multidisciplinary building-services design practice with experience of concept and feasibility studies for complex facilities. Relevant capability includes developing ventilation architectures, nuclear ventilation philosophies, contamination-control approaches, mechanical and electrical building-services designs, maintenance and handling arrangements, and early-stage capital cost estimates. Suppliers with experience in fusion, nuclear, highly regulated industrial, laboratory or similarly safety-critical environments are likely to be well placed to demonstrate understanding of the STEP context. The work will require the ability to translate technical and operational requirements into a building layout strategy and a credible HVAC plant basis. The buyer has indicated that SMEs may be suitable, so a specialist consultancy or appropriately experienced consortium could prepare for the expected competition.

Notice Title

HVAC concept-level study

Notice Description

The purpose of this Task Order will be to produce a concept-level Heating, Ventilation and Air Conditioning (HVAC) study to support the ongoing development of the Spherical Tokamak for Energy Production (STEP) prototype fusion facility, together with its associated maintenance, handling, and supporting infrastructure. The study shall provide the technical basis for the development of the facility HVAC architecture and ventilation strategy and shall inform the wider Tokamak Building design. The outputs of the study shall support the development of the building layout, contamination control strategy, nuclear ventilation philosophy, and the preparation of a Rough Order of Magnitude (ROM) cost estimate for the HVAC plant and associated systems. IMPORTANT: this is a planned procurement notice published per the rules set out in the Procurement Act 2023. This notice does not constitute an invitation to quote, tender, or to provide a proposal. This Planned Procurement Notice has been published to raise awareness of the requirement and to alert suppliers of the need to register on the UKFE Delta portal should they choose to tender for this (and other UKFE) requirement should it be advertised to open competition.
