The Coalition for the Energy Efficiency of Buildings (CEEB) was established by the Green Finance Institute, with support from E3G, as its flagship coalition in December 2019.
Made up of more than 365 individual members from the finance, property and energy sectors, and across policy, academia and non-profit organisations, the CEEB’s remit is to develop the market for financing a net-zero carbon and climate-resilient built environment in the UK, initially by catalysing the widescale retrofitting of residential buildings.

In May 2020, the CEEB released Financing energy efficient buildings: the path to retrofit at scale assessing the market for energy efficiency improvements in UK homes across the owner-occupied, private-rented and social-rented tenures, and identified specific initiatives where finance and government can bridge investment gaps to drive systemic change.

The report outlines a portfolio of 21 demonstration projects, developed collaboratively by members. It has been positively received by the sector and the Department for Business, Energy and Industrial Strategy (BEIS), which called it “a positive step towards achieving our Green Finance Strategy ambition to build the market for green home finance”.

In December 2020, the Coalition’s Zero Carbon Heating Taskforce released Financing zero carbon heat: turning up the dial on investment, a major piece of analysis of the investment barriers to widescale decarbonisation of the UK’s domestic heating and details of a portfolio of 12 financial solutions and policy, regulatory and data enablers to overcome them, turning the challenges into an opportunity for the finance sector and a green economic recovery.
