Summary of the contracting process

The London Borough of Sutton is seeking to appoint contractors for the "Provision of Carshalton and Clockhouse Retrofit Works" under its Sutton Housing Partnership initiative. This procurement involves significant energy refurbishment works on 44 properties across multiple UK regions, aiming for an EPC rating of C by 2030. Key improvements include external wall insulation, new double glazing, loft insulation, and Passive house ventilation systems. The tender is currently in the open competition stage with a submission deadline of 3rd July 2026. The contract period is set to commence on 1st September 2026 and conclude on 28th February 2027. The entire project is valued at £1,680,000 and will adhere to PAS2035 and requires PAS2030/TrustMark certified installers.

This tender presents an excellent opportunity for businesses specialising in construction work and energy efficiency improvements, particularly those with PAS2030 certification. The London Borough of Sutton intends to award contracts to two contractors, each responsible for 22 properties. With a procurement process that emphasises price (70%) and quality (30%), including factors such as resident communication and social value, businesses attentive to these elements and with experience in delivering high-standard retrofit projects will likely find themselves well-positioned. The open procurement method fosters competitive participation, making it an attractive proposition for SMEs looking to grow their presence in the public sector and expand their service offerings in sustainable construction and refurbishment.

Notice Title

Provision of Carshalton and Clockhouse Retrofit Works (Sutton Housing Partnership)

Notice Description

Sutton Housing Partnership (SHP) manages around 6000 properties on behalf of London Borough of Sutton (LBS), with a further 1500 in leaseholder ownership. As part of its climate emergency declaration and commitments, and to ensure that the property portfolio achieves the minimum EPC of C by 2030, SHP has started an ambitious energy refurbishment programme. The vast majority of SHPs property portfolio is an EPC D or above, with many already achieving an EPC C rating. However, there are some properties that fall in the lower half of the D banding and below. Many of these are hard to treat, and particularly hard to heat. Given the recent energy fuel increases this has put additional pressure on households who may already be struggling to heat their homes. The scope of this project is to deliver the following to each of the properties: * external wall insulation * double glazing including front and rear doors * loft insulation installation. * Passive house ventilation systems The project covers a total of 44 properties. SHP intends to appoint two contractors, with the two highest scoring suppliers each being awarded a contract to deliver retrofit works to 22 properties. The final property addresses will be provided to the successful contractors upon contract award. The purpose of the works is to improve the energy performance of the housing portfolio and ensure that all properties achieve a minimum Energy Performance Certificate (EPC) rating of C. As with all government funded projects, this project must be delivered in compliance with the PAS2035 process, and all installers must hold appropriate PAS2030/TrustMark certification for any measures installed in the programme.
