PfH Decarbonisation, Retrofit and Planned Works Framework for Wales

PfH Cymru (Procurement for Housing Wales) wishes to establish a Wales-specific Decarbonisation, Retrofit and Planned Works Framework Agreement. Established in 2004, Procurement for Housing (PfH) is a national procurement consortium dedicated to the social housing sector and supported by the National Housing Federation (NHF), Chartered Institute of Housing (CIH) and HouseMark.

Collectively our Members manage more than 90% of the UK's social housing stock, with PfH helping them to achieve efficiency savings using a wide range of services including framework agreements, dynamic purchasing systems, spend analyses, strategy reviews, consolidated billing and comprehensive reporting. PfH is a contracting authority under section 2 of the Procurement Act 2023 and a centralised procurement authority under section 1(4) of that Act.

Please refer to www.pfh.co.uk for additional information. Suppliers will be able to apply for both regions but for only one of the value bands per lot pair i.e. one of lot 4 and 5, one of lot 6 and 7, one of lot 8 and 9 and one of lot 11 and 12.

The number of suppliers we anticipate allocating to each lot and region are set out in the procurement documentation (see Document 1). PfH reserves the right to award places on the framework to a greater or fewer number of suppliers, depending on the bids received.
