Ecology launches free retrofit advice for borrowers

Written by Lori Campbell on 14th Oct 2025

Good Egg company Ecology Building Society has teamed up with retrofit specialists Retrogreen to offer its borrowers free, personalised advice on how to make their homes greener, warmer and cheaper to run.

The new partnership gives Ecology’s renovation mortgage customers free access to Retrogreen’s online retrofit tool – designed to help homeowners understand which energy-saving upgrades make the most sense for their property, what they’ll cost, and how much they could save.

Many people want to improve their home’s energy efficiency but don’t know where to start. Common barriers include confusion about what work is needed, how to find trusted tradespeople, and worries about cost.

Closing the ‘confidence gap’

“Time and again we hear that consumers are interested in making green home improvements but often they don’t know where to start,” says Daniel Capstick, Ecology’s Senior Mortgages Product and Proposition Manager. “That’s why we’ve partnered with Retrogreen to bridge that ‘confidence gap’.”

Retrogreen’s tool lets users explore potential upgrades, from insulation to heat pumps, and see how these could improve their property’s Energy Performance Certificate (EPC) rating or even its value. Borrowers can filter options based on comfort, affordability or environmental impact, and then connect with vetted, accredited installers to get the work done.

The initial online assessment is free to Ecology borrowers, with discounted access to a full end-to-end retrofit management service. Ecology plans to extend the offer across its wider membership in future.

“We’re proud to partner with Ecology to make trusted retrofit advice accessible to more homeowners,” says Colin Calder, CEO at Retrogreen. “Our goal is to give people the confidence to act – showing them which upgrades make sense and connecting them with the right professionals to deliver them properly.”



Green rewards for greener homes

Ecology already rewards borrowers who make their homes more energy efficient through its C-Change discount, which can reduce mortgage rates by up to 1.50 per cent depending on how much the property’s energy performance improves.

The Society’s renovation mortgages also offer cashback for installing heat pumps – £500 for an air source model or £1,000 for a ground source system.

With energy costs still high and climate goals growing more urgent, the partnership is another example of how Ecology is helping its members turn good intentions into real-world impact.
