This dashboard displays data from our Sustainability Tracker, a yearly survey with around 2,000 UK adults a year, sampled and weighted to represent the UK population.

This page includes data from the past three years on: 

  • Energy usage
  • Smart energy tariffs
  • Home insulation
  • Heat pumps
  • Solar panels
  • Energy batteries

Energy usage

Since June 2023, we have asked UK adults what actions they take to reduce the amount of energy they use in their home. Additionally, the last two years we asked what they currently use as the main source to heat their home.


Smart energy tariff

In June 2025 we asked UK adults if they were on an electricity tariff or recieve discount offers from their electricity provider which encourage them to use more or less electricity depending on the time of day.

Home insulation

In June 2025 we asked homeowners what insulation their homes have and any changes they have made in the last two years. We then asked if they are considering making any improvements in the next couples of years and what, if anything, would stop them from insulating their home further.

Heat pumps

Since June 2023, we have asked homeowners who do not currently have a heat pump whether they have heard of heat pumps as a home heating system before and, if so, whether they know what they are. Those who knew what they are were asked whether they would consider installing a heat pump in their home if they needed to replace their current heating system in the next 12 months and what would prevent them from installing a heat pump for their home.

Solar panels and energy batteries

In June 2025 we asked homeowners if they have solar panels and energy batteries. If they did not we asked if they would consider installing them in the future and what, if anything, would prevent them from insulating solar panels.
