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).

What is the Warm Homes Obligation?

The WHO scheme is not a loan or charity fund – it is an obligation 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, you may receive:

Low-carbon heating systems such as air source heat pumps
Loft and wall insulation
Other approved energy efficiency measures such as solar panels and battery storage

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
