## Description
This procurement process is being managed by Transport for London ("TfL") on behalf of the Greater London Authority ("GLA").
This process is conducted as an innovation partnership under Regulation 31 of the Public Contracts Regulations 2015.
The GLA has identified the need for an innovative solution that cannot be met by what is available on the market: a scaleable performance assured standard "whole house" net zero energy ("NZE") solution for retrofitting homes at an economic price point. This process aims at the development of that innovative solution; and the subsequent purchase of it under a framework agreement, provided that specified performance levels and maximum costs are met.
If successful, the process will: (1) Develop a solution that does not presently exist in the market: (2) Provide an effective route to market for pipeline projects from Housing Providers (as defined in II.2.4); and (3) Develop a robust supply chain to deliver NZE solutions.
