Warm Homes Obligation (WHO)Information & Guidance for UK Residents

Warm Home Obligation Grant

All UK citizens

have a right

to a warm home

Stay warm, save money, and improve your home’s energy efficiency with support from the Warm Homes Obligation (WHO).

WHO is a government requirement placed on energy suppliers to help households improve energy efficiency, lower bills, and reduce carbon emissions. Under this obligation, energy companies must provide funding and support for eligible households to make their homes warmer, healthier, and more affordable to heat.

What is the Warm Homes Obligation?

The WHO scheme is not a loan or charity fund – it is a legal obligation on energy companies to deliver energy-saving measures to households across the UK. This includes financial support for insulation, heating system upgrades, and other efficiency improvements.

What support is available?

Depending on your eligibility, your energy supplier may fund:

Loft insulation
Solid wall insulation
Boiler replacements
Low-carbon heating systems such as heat pumps
Other approved energy efficiency measures

Why it matters

Energy companies are legally required to provide this support
Households benefit from lower energy bills and warmer homes
The scheme contributes to the UK’s carbon reduction targets
