Frequently asked questions

Can I get free underfloor insulation in your area through the Warm Homes Plan?

Yes. Underfloor insulation is available under the Warm Homes Plan for eligible your area households with suitable suspended timber ground floors. If your household receives a qualifying benefit and your EPC rating is D or below, submit the form to check whether your your area property qualifies.

What type of floor is suitable for Warm Homes Plan underfloor insulation?

Warm Homes Plan-funded underfloor insulation is most commonly installed in properties with suspended timber ground floors, where insulation is fitted between the joists from beneath via crawl space access or lifted floorboards. Solid concrete floors can be insulated but require a different approach and are less common under the scheme.

How is underfloor insulation installed?

For suspended timber floors, rigid insulation boards or mineral wool batts are fitted between the floor joists, usually from beneath via an accessible underfloor void. In most cases the work is completed without lifting floorboards. The process typically takes one day in a your area property.

Who qualifies for free underfloor insulation under the Warm Homes Plan?

Eligibility requires a qualifying benefit (Universal Credit, Pension Credit, Income Support, or similar) and an EPC rating of D, E, F or G. The property must have a suitable ground floor construction. Owner-occupiers and private tenants with landlord permission can both apply.

How much can underfloor insulation save on energy bills?

The Energy Saving Trust estimates underfloor insulation saves a typical semi-detached your area home around £60 to £115 per year, depending on property type and energy prices. Combined with loft and wall insulation, the total saving can be considerably higher.

Is underfloor insulation disruptive to fit?

In most cases underfloor insulation is fitted from beneath through the underfloor void, so there is minimal disruption inside your your area home. If access is only available from above, some floorboards may need to be temporarily lifted, but these are refitted on completion.

These low-cost improvements can start reducing your bills straight away.
