What schemes are covered in the UK home energy upgrades table?

The table covers Boiler Upgrade Scheme grants for heat pumps and biomass boilers, solar PV deployment, and Energy Company Obligation (ECO) energy efficiency installations.

Which heat pump technologies are tracked in the UK data?

It tracks air source heat pumps, ground source heat pumps, shared ground loop heat pumps, and biomass boilers across England and Wales and English regions.

How far back does the UK home energy upgrades data go?

Monthly statistics from the Department for Energy Security and Net Zero are available since 2010.

What units are used to measure UK solar PV and ECO measures?

Solar PV deployment is recorded in installations and megawatts (MW), while grant schemes track applications, vouchers, redemptions, and installed energy efficiency measures.

About this data

Frequently asked questions

What schemes are covered in the UK home energy upgrades table?: The table covers Boiler Upgrade Scheme grants for heat pumps and biomass boilers, solar PV deployment, and Energy Company Obligation (ECO) energy efficiency installations.
Which heat pump technologies are tracked in the UK data?: It tracks air source heat pumps, ground source heat pumps, shared ground loop heat pumps, and biomass boilers across England and Wales and English regions.
How far back does the UK home energy upgrades data go?: Monthly statistics from the Department for Energy Security and Net Zero are available since 2010.
What units are used to measure UK solar PV and ECO measures?: Solar PV deployment is recorded in installations and megawatts (MW), while grant schemes track applications, vouchers, redemptions, and installed energy efficiency measures.
