C-Change discounts

Our C-Change discounts explained

As a building society with a unique mission to build a greener society, we only lend on projects and properties that support our aims through their reduced impact on our environment. Making your home energy efficient is a major way you can support tackling climate change - while saving on your energy bills. We reward borrowers whose properties are energy efficient, and therefore have lower C02 emissions, and help them save money on their mortgages with our C-Change discounts. We call our discounts ‘C-Change discounts’ simply because we’re aiming to make a ‘sea-change’ of difference to our climate with each property or project we fund.

The level of our C-Change sustainable homes, C-Change retrofit or C-Change energy improvements discount that applies is based on the Energy Standard rating achieved on the self-build, renovation, conversion or energy improvements when the work is completed. The discount is applied from the date we receive evidence that the work has been completed and the required Energy Standard rating has been achieved.

For new builds and existing energy efficient homes: C-Changes sustainable homes discount

Our C-Change sustainable homes discount applies to new and existing energy efficient homes and extensive retrofits using the Passivhaus EnerPHit methodology. Once your build is complete, you need to provide an Energy Standard certificate and Architect/Building Control certificate for us to apply the Sustainable C-Change discount. The discount is applied from the date we receive all the required documentation and is based on the Energy Standard rating the property achieves.

For homes needing extensive renovations / energy efficiency improvements: C-Change retrofit discount

The C-Change retrofit scheme offers a discount of 0.25% from our Standard Variable Rate for each rating improvement in your home’s Energy Performance Certificate (EPC). This could be either its Energy Efficiency or Environmental Impact rating – whichever is the highest.

For example, if either EPC rating improves from E to C after the works to the property are completed, a discount of 0.50% will be available on the whole of the mortgage, for the duration of the loan. The discounts are deducted from our Standard Variable Rate (currently 4.65% – the overall cost for comparison is 4.80% APRC).

To apply the discount, we need to receive an EPC before you undertake works to your home and another EPC once works are completed. We will compare the revised EPC with the original rating, and apply the discount based on the grade improvement achieved. Until we have received your revised EPC, we will charge interest at our Standard Variable Rate. You can find out more by downloading Our C-Change discount leaflet.

For funds borrowed to install energy efficiency measures or renewable energy systems: C-Change energy improvements discount

The C-Change energy improvement scheme offers a discount of 1% on funds borrowed for qualifying energy measure installations (see list in table) and is applied once work is completed and evidenced by invoices. Please note the discount is applied to funds borrowed for energy improvement measures only and our Standard Variable Mortgage Rate will apply to the rest of the mortgage.

For example, if you borrow £150,000 and £50,000 is used for energy improvements, once all work is completed and evidenced, we would apply a 1% discount from our Standard Variable Rate to the £50,000 used for energy improvements and our Standard Variable Rate would apply to the rest of the mortgage.
