Even if you already have loft insulation, it may not be sufficient as it is recommended that you have 270mm (10.5 inches) of insulation. Installing loft and cavity wall insulation can save up to £310 on your annual heating bill and reduce your home’s carbon dioxide emissions by up to 1.3 tonnes per year.  Solid wall insulation could save you up to £490 annually and reduce your carbon emissions by up to 1.9 tonnes per year.

Alternatively, you may be eligible for free loft and cavity wall insulation if a member of your household is in receipt of certain means-tested benefits or if your home qualifies due to its poor energy efficiency.

Funding is available from energy companies under the Energy Company Obligation (ECO) or up to £10,000 under the Green Homes Grant.
