Underfloor Insulation

A Brief Overview

Many older houses with suspended timber floors might have undesired air penetration (draughts) and inadequate floor insulation (usually no insulation when built), resulting in increased energy bills and poor thermal comfort.

How does this Work?

  • These issues may be addressed by properly installing underfloor insulation.

  • Insulating a suspended wood floor helps decrease draughts while also reducing heat loss through the floor.

  • The advantages can be considerable for inhabitants of homes with uninsulated floors because 10 - 20% of a building's heat loss can occur via the floors if they are not insulated to a decent quality.

Your Eligibility for this Grant

  • You must ensure your loft is empty of all belongings otherwise the installation of the insulation will not be able to proceed. If the loft is converted in some way then you may wish to consider FREE Room in Roof insulation instead.

  • The loft must be accessible through a hatch and not be boarded. If currently boarded then it must be only a small area of the loft and you may wish to lift the boarding you have to proceed with the FREE grant.

  • The property should be located in England, Scotland or Wales and be heated by a gas, oil, LPG, electric boiler or electric storage heaters (ESH).

  • You must be the Homeowner, Landlord or a Private Tenant. Private Tenants must have their Landlord permission. Landlords must have an eligible ECO3 Tenant living in the property that requires insulation.

  • Also, Housing Associations can claim insulation grants if their properties are heated by any type of electric heaters and they have eligible ECO3 Tenants.

  • If your loft’s current insulation is 100mm (below joist level) then you can have it topped up to 270-400mm.

  • If you have ‘downlights’ in the ceiling under the loft then you may be required to buy £5 safety covers for each of them.
