The UK’s green mortgage market is showing signs that it is ready for lift off. Encouraged by the innovation of peers in this space, banks and building societies in the UK are launching green mortgage products at an ever increasing rate. Green Mortgage products come in a variety of different forms, but all aim to incentivise homeowners to invest in improving the energy efficiency of their properties.

The opportunity for lenders in this space is huge. The UK Committee on Climate Change has estimated that £250 billion needs to be invested in UK home upgrades by 2050, which means there is the potential for significant capital flows in green mortgages in the coming years. Meanwhile, there are other levers in play, with policy makers, NGOs and financial regulators increasingly demanding that lenders examine the energy efficiency of their mortgage portfolios.

The aim of this page is to provide a holistic overview of the Green Mortgages in the UK. This page is aimed at stakeholders who are focused on the built environment and how to finance the decarbonisation of the sector.

The GFI invites any financial institutions who have recently launched a green mortgage product in the UK that they believe should be listed in the table below to get in touch with greenmortgages@gfi.green.
