If you're building or buying an eco-home, our sustainable homes discount could offer a discount of up to 1.25% from our Standard Variable Rate (4.90% - the overall cost for comparison is 5.1% APR).

The level of discount offered depends on the energy standard achieved in your home - so the more efficient your home is, the more you save on your mortgage.

Who is it for?

How to apply

Our C-Change sustainable homes discount is available on our residential, buy-to-let, housing co-operative, housing association and part-residential mortgages.

You can find more details about who can apply on each mortgage page, or by downloading About you.

The discount is most applicable to new and existing energy efficient homes - the higher the energy rating, the greater the discount.

We dreamt of building a home that was a flexible living and working space. And we wanted to hold on to our ideals of sustainable living. But all that’s hard to achieve when you’re living in the heart of a city. With the support of Ecology Building Society, we’ve managed to realise our dream.
