Retrofit Services and Partnerships Hub

Title-Photo-scaled-1824x1026

Cross-industry collaboration is essential to support homeowners on their green home improvement, building and purchasing journeys. A growing number of UK lenders and financial intermediaries are recognising the value of providing retrofit guidance, planning tools, signposting and support services – which can help make financing energy efficient and adaptive home upgrades easier and more accessible for homeowners. There are also certain lending solutions that integrate sustainable features and benefits delivered by third-party providers.

The GFI has surveyed the market and compiled a database of the main retrofit support and partnership services currently available from regulated UK lenders and home finance intermediaries below. This includes the third parties they are partnering with to deliver these services (where applicable).

The services have been organised into four main categories:

Lender Retrofit Planning Tools and Surveys

Usually carried out at time of application alongside a standard mortgage valuation to assess and recommend a schedule of works to improve the property’s energy performance.

Independent Mortgage Advice and Retrofit Support

Regulated mortgage advice services paired with planning tools and referral pathways to retrofit delivery partners.

Special Offers on Partner Products or Services

Discounts and promotional offers on products or services relating to home energy efficiency, e.g. solar panels and battery, or a heat pump.

Integrated Features of Green Lending Products/Propositions

Integrating third-party services like low or zero-carbon housebuilding, bio-based building services or carbon credit/offsetting schemes with home financing products or propositions.

Note to providers featured in the Hub:

If you wish to notify us of a new entry or amend an existing entry, please contact built.environment@gfi.green. The Hubs are reviewed and updated as required on a quarterly basis, unless the submission is urgent (i.e. to correct a factual inaccuracy).
