This procurement is related to industry-specific software and services, particularly in architectural, engineering, and construction fields. The procurement process aims to engage suppliers in understanding market capabilities and explore potential solutions before commencing formal tendering processes. Located in Bootle, Merseyside, under the oversight of the Building Safety Regulator, this initiative is set to span from 2026 with key engagement events scheduled until 27th March 2026. Interested suppliers are encouraged to participate in online events throughout March to discuss commercial options and procurement models relevant to energy performance calculation for buildings. This procurement offers significant opportunities for businesses specialising in software development, engineering consultancy, and construction-related compliance services. Particularly, small and medium enterprises (SMEs) that can offer innovative solutions in energy performance calculations could find value in competing for these contracts, given the procurement's alignment with evolving building regulations and energy standards. The upcoming contracts are expected to be divided into lots focusing on maintaining, updating, and developing technical guidance. Notably, the development, maintenance, and enhancement of the National Calculation Methodology (NCM) and its associated tools and interfaces form the core of upcoming opportunities, providing scope for sustained business growth over an estimated three-year initial duration. ## Notice The Building Safety Regulator (BSR) is housed within the Health and Safety Executive (HSE) and is responsible for ensuring that buildings across Great Britain are compliant with statutory requirements. In accordance with the Building Regulations 2010, the Secretary of State has approved the National Calculation Methodology (NCM) to calculate the energy performance and asset rating of buildings other than dwellings. The Technical Policy Team (TPT), operating within the BSR, is responsible for maintaining, updating and developing technical guidance associated with Building Regulations including the management of NCM. HSE is seeking to engage with the market in advance of a planned procurement relating to the National Calculation Methodology (NCM) The scope of any future procurement may include (but is not limited to): * NCM Modelling Guide (England) * NCM Databases * SBEM code * SBEM Technical Manual * iSBEM * iSBEM user guide NCM is associated with, but does not currently include, the following functions: Calculation of Operational Ratings - https://assets.publishing.service.gov.uk/media/5a78b842ed915d07d35b1e49/998942.pdf EPC Register - https://www.gov.uk/find-energy-certificate NCM Scotland - https://www.uk-ncm.org.uk/download.jsp?id=38 NCM Wales - https://www.uk-ncm.org.uk/download.jsp?id=39 NCM Northern Ireland - https://www.uk-ncm.org.uk/download.jsp?id=14 NCM States of Jersey - https://www.uk-ncm.org.uk/download.jsp?id=18 Non-Domestic Energy Assessment Procedure (Ireland) - https://www.seai.ie/ber/support-for-ber-assessors/neap#comp0000621c848a0000001d15584f Third-party software validation - https://assets.publishing.service.gov.uk/media/68f8b1daec6267c615ed8f64/2025-10-15_NCM_approved_software_programs_for_buildings_other_than_dwellings.pdf The future procurement is intended to be split into the following lots: Lot 1 Development of the National Calculation Methodology (NCM) * Maintain and update the NCM to reflect evolving building regulations and energy standards. * Advise the Building Safety Regulator (BSR) on technical adjustments needed to remain compliant with Part L of the Building Regulations.
