Summary of the contracting process

The Scottish Government, based in Edinburgh, conducted a procurement process for the project titled "DECC-Energy Performance of Housing Stock Research," focusing on services within the general public services industry category. This project was located in the UKM region, Edinburgh specifically, and was initiated as a tender to support Scotland's ambition to reach net zero emissions by 2045 by analysing the performance of Scottish housing stock according to new EPC ratings. The process involved an open procurement method, and the award stage was completed with a contract value of GBP 38,025, signed on 2 June 2025. The tender period ended on 14 April 2025, and the award process commenced on the same day.

This tender presents notable opportunities for companies involved in energy efficiency and building performance analysis, particularly those experienced in EPC rating systems and environmental data analysis. Small and medium-sized enterprises (SMEs) like Cotality | Parity Projects, which secured the contract, demonstrate that businesses with relevant expertise and innovative solutions can significantly benefit from such governmental projects. Companies equipped with capabilities in advancing clean heating technologies and providing impactful energy assessments for residential buildings will find aligning with Scotland's strategic environmental objectives promising for business growth.

Notice Title

DECC-Energy Performance of Housing Stock Research

Notice Description

The Scottish Government has legally committed to reach net zero by 2045 for the benefit of our environment, people, and prosperity and is committed to taking the required action. We have confirmed in the 2024 to 2025 Programme for Government that tackling the climate emergency is a priority. To meet net zero, transformation will be required across all sectors of our economy and society, including from our homes and places of work. Heating Scotland's buildings accounts for 20% of emissions - the third largest cause of greenhouse gas emissions in Scotland - and therefore reducing emissions from this sector is vital to reaching the Government's ambition. The Scottish Government published its Heat in Buildings Strategy in October 2021, which set out our vision for decarbonising Scotland's buildings by 2045. We continue to lay the foundations to support the growth of clean heating and energy efficiency in Scotland. The objective of this work is to provide an analysis of the Scottish housing stock's performance in each of the new EPC ratings set out above, using the Scottish EPC wrapper and HEM. This includes how homes would be rated in the new EPC ratings compared with how they are rated in the current EPC system, and then also how energy efficiency improvements might impact ratings across types of homes and in different sectors.

The Scottish Government has legally committed to reach net zero by 2045 for the benefit of our environment, people, and prosperity and is committed to taking the required action. We have confirmed in the 2024 to 2025 Programme for Government that tackling the climate emergency is a priority. To meet net zero, transformation will be required across all sectors of our economy and society, including from our homes and places of work. Heating Scotland's buildings accounts for 20% of emissions - the third largest cause of greenhouse gas emissions in Scotland - and therefore reducing emissions from this sector is vital to reaching the Government's ambition. Energy Performance Certificates (EPCs) are being reformed this year, with new regulations due to be laid in Parliament in September. When these regulations come into force in autumn 2026, this will mean that the ratings shown on a domestic EPC will be different to the current ones. The new 'headline' rating will be called the Heat Retention Rating (HRR) and will demonstrate the fabric efficiency of the home or building. The new EPC will also have a new Heating System Type Rating (HSTR) showing whether the installed heating system is polluting, hybrid or clean, its emissions and efficiency. We expect that Parliament will want to understand the performance of the stock against the new ratings - in particular the numbers of properties (and their tenures) falling into the new Heat Retention Rating bandings (A-G) from day one. The objective of this work is to provide an analysis of the Scottish housing stock's performance in each of the new EPC ratings set out above, using the Scottish EPC wrapper and HEM. This includes how homes would be rated in the new EPC ratings compared with how they are rated in the current EPC system, and then also how energy efficiency improvements might impact ratings across types of homes and in different sectors.

Renewal: An optional 2 month extension will be available to be utilised at the discretion of Scottish Ministers.

                "description": "The Scottish Government has legally committed to reach net zero by 2045 for the benefit of our environment, people, and prosperity and is committed to taking the required action. We have confirmed in the 2024 to 2025 Programme for Government that tackling the climate emergency is a priority. To meet net zero, transformation will be required across all sectors of our economy and society, including from our homes and places of work. Heating Scotland's buildings accounts for 20% of emissions - the third largest cause of greenhouse gas emissions in Scotland - and therefore reducing emissions from this sector is vital to reaching the Government's ambition. Energy Performance Certificates (EPCs) are being reformed this year, with new regulations due to be laid in Parliament in September. When these regulations come into force in autumn 2026, this will mean that the ratings shown on a domestic EPC will be different to the current ones. The new 'headline' rating will be called the Heat Retention Rating (HRR) and will demonstrate the fabric efficiency of the home or building. The new EPC will also have a new Heating System Type Rating (HSTR) showing whether the installed heating system is polluting, hybrid or clean, its emissions and efficiency. We expect that Parliament will want to understand the performance of the stock against the new ratings - in particular the numbers of properties (and their tenures) falling into the new Heat Retention Rating bandings (A-G) from day one. The objective of this work is to provide an analysis of the Scottish housing stock's performance in each of the new EPC ratings set out above, using the Scottish EPC wrapper and HEM. This includes how homes would be rated in the new EPC ratings compared with how they are rated in the current EPC system, and then also how energy efficiency improvements might impact ratings across types of homes and in different sectors.",

If the bidder is unable to confirm (b) they must provide an improvement plan, signed by their Director, which improves the payment performance.
