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 two years on: 

  • Energy usage,
  • Smart energy tariffs
  • Home insulation, and
  • Heat pumps

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.

Click through the charts below to see this data and differences for reducing energy use by age, household income, tenure and family type.


Smart energy tariff

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

Further smart energy tariff data will be added in January 2026.

Home insulation

In June 2025 we asked homeowners what insulation their homes have any 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.

Barriers to further insulating home

Further data will be added in January 2026.

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.
