Santander launches online tool to help homeowners improve their property and reduce future household bills

22 October 2025

Santander UK has today announced the launch of a new Home Energy Saving Tool, which will allow homeowners to review their home’s energy efficiency and receive a personalised action plan to identify what improvements can be made, and how they can help reduce their household bills in the long term.

The tool, launched in partnership with the Energy Saving Trust (EST), a leading independent voice on climate action, takes around six minutes to complete and uses details including a customer’s postcode to assess their property. It will then create a plan to help them identify:

  • Suggested home improvements and their costs;
  • The estimated annual home energy bill savings;
  • An indication of the property’s current and estimated (after improvements) Energy Performance Certificate rating; and
  • The property’s current and estimated CO2 emissions.

Research from Santander(1) found that more than half (53%) of homeowners would be more likely to make energy efficiency improvements if they knew it would save them money on other areas like their energy bills.

Speaking about the launch of the tool, Mick Taylor, Head of Green Finance, Homes at Santander said:

“We can all feel the change in the air as the autumn breeze starts to bite, coupled with the recent 2% rise in the energy price cap, it’s natural that homeowners are starting to think about ways to keep bills as low as possible, longer term. Our new tool quickly highlights where homeowners can invest their time and money to improve the energy efficiency of their property, as well as what the impact of those improvements would be in pounds and pence to their annual energy costs in future.”
