Estimates for a typical three-bedroom semi at the current price cap, from the Energy Saving Trust. Your home will differ; the order rarely does.
Rated heating and insulation firms near youThey are the Energy Saving Trust's estimates for a typical three-bedroom semi-detached house in Great Britain at the current price cap. A flat saves less, a detached house more. The order of what to do first is what matters, and that rarely changes.
Private tenants can qualify for the Warm Homes Local Grant in England and the Nest scheme in Wales with the landlord's consent, and landlords now have to meet a minimum energy rating. Council and housing association tenants should ask the landlord: they have their own funded programmes.
The grants use accredited installers, which you can find through the scheme itself. For anything you pay for yourself, the local directory shows heating and insulation firms rated by neighbours, and nobody can pay to be listed first.
