The timescale of ADD2488 says a finalised report for your Roofs designed to cool programme will be produced in February 2021, and that the project will be closed in March 2021. Could you provide me with the report and any associated findings?

In the autumn of 2020, ADD2488 was approved to procure the services of a supplier to carry out work to establish an evidence base and implementation mechanism for cooling London’s existing homes and buildings, and reducing intensification of the urban heat island (UHI) effect. The work would have also explored opportunities to support jobs.

Following a poor response to the initial invitation to tender, in discussions with the market, it became clear the brief was for two separate pieces of work requiring different skill sets. As a result, the value of the works was increased from £20,000 to £40,000 to reflect the wide scope and attract a wider pool of suppliers. An ADD2354 was prepared to reflect the additional value. This was submitted to the Greater London Authority’s Corporate Investment Board (CIB) on 6th September 2021 and approved. It is anticipated that the work will be completed by March 2022.
