The Green Finance Institute (GFI), in partnership with Lloyds Banking Group and NatWest Group, has unveiled a new report outlining the potential for an innovative green finance mechanism, Property Linked Finance (PLF), to channel billions of pounds worth of private investment into sustainable retrofit across the UK.

The report sets out a series of guiding principles and key steps for how PLF should be designed and launched in England and Wales, including calling for enabling legislation from the government as well as the establishment of pilot programmes, initially in the commercial sector.

Research from the GFI – the UK and Europe’s principal forum for innovation in green finance markets – estimates that PLF, a green financial solution not currently available in the UK, has the potential to catalyse between £52 bn (€62 bn) and £70 bn of private investment into decarbonising the residential market across England, Scotland and Wales – materially contributing towards the UK’s net-zero ambitions and helping to improve the UK’s inefficient building stock which is responsible for 23% of the UK’s total greenhouse gas emissions.

An estimated investment of £360 bn is needed to decarbonise the UK’s commercial and residential buildings by 2050 – an investment that cannot be met by the public purse alone. PLF offers a vital new mechanism to crowd in private capital and to help achieve the necessary investment into the installation of low carbon technologies, energy efficiency and climate resiliency projects in the UK, with the potential to scale globally.

PLF enables access to affordable and long-term funding for environmental improvements for buildings by linking the finance agreement to the property, rather than the owner. This means the payment obligation can transfer to the new owner when it is sold.

Property owners would only pay for energy efficiency measures up until they sell their property, or the measures have been paid off, while new buyers benefit from a more energy efficient, potentially more desirable property, in return for continuing to make regular payments towards the upgrades. The mechanism would work both for homeowners as well as owners of commercial properties.

Eloise Henderson-Day, PLF programme director, Green Finance Institute, said: 'The Green Finance’s Institute’s vision is to create a thriving market that rapidly deploys capital towards the decarbonisation of UK buildings.

'Working with Lloyds Banking Group and NatWest Group, we have developed a ‘greenprint’ to launch and grow PLF in the UK, which has the potential to unlock billions of pounds in investment to retrofit our buildings and increase their energy efficiency and resilience.

'Successfully introducing PLF in the UK will require a collaborative approach across the entire built environment ecosystem.'

Andrew Asaam, homes director, consumer lending, at Lloyds Banking Group, said: 'We’re pleased to support The Green Finance Institute’s research into the decarbonisation of UK properties. Exploring innovative solutions to increase investment and interest in energy efficiency initiatives is a positive step forward in helping the country meet its 2030 goals. However, there is still much work to do, and it will take the ecosystem working together to ensure ambitions are realised.'

Lloyd Cochrane, head of mortgages at NatWest Group said: 'The report released today by The Green Finance Institute shows the potential that Property Linked Finance has to make a major contribution to efforts to decarbonise the UK property sector.

'We are supportive of measures that attract private investment into solutions that will accelerate energy efficiency initiatives. The investment required to meet UK decarbonisation targets can’t be met by just one part of industry or government, so working like this to outline the opportunities and challenges that need to be addressed to make alternative funding concepts a reality is really important.'
