Thinking about making your home more energy efficient? We’ve an energy-saving tool, provided by Energy Savings Trust, that outlines changes you could make – and how much you could save. If you’re ready to put those ideas into action, our new green additional borrowing range (for existing Leeds Building Society borrowers) could help.
Draw up an energy-saving action plan
Saving energy doesn’t have to be guess work. Our Home Energy Saving Tool is here to help.
Just answer a few questions about your property and your current energy spending. The tool will calculate where and how you could make energy improvements, showing you how much money you could save and helping to reduce the impact your home has on the environment.
If you don't have time to answer all the questions in one go, don’t worry – you’ll get a unique code so you can come back and finish it off later.
Get started with the Home Energy Saving Tool and get a tailored plan with recommended home improvements and potential savings.
Introducing green additional borrowing
Once you’ve got your personalised action plan, you’ll see how much difference some home upgrades could make – from better insulation or new windows to heat pumps or low energy lighting.
If you’re ready to put those ideas into action, our new green additional borrowing product could help you get there. It’s designed to support you in funding energy efficient home improvements by borrowing more against your home.
If you’re an existing Residential or Buy to Let mortgage holder, green additional borrowing means you borrow more on your mortgage to support a range of energy-efficient home improvements:
- Air source heat pumps
- Ground source heat pumps
- Cavity wall insulation
- Double/triple glazing
- Electric car charging installation
- Loft insulation
- Underfloor wet heating systems
- Solar PV and storage batteries
- Low energy lighting
- Smart water tanks
Take a look at our green additional borrowing range.
You’ll need to provide a quote for the proposed work when applying. Affordability and lending criteria apply.
With our green additional borrowing, you could bring your energy efficient improvements to life.
Your property could be repossessed if you don't keep up your mortgage repayments.
