Insulating the floor in your home is a useful way to maintain heat, as even if you’ve got your loft and walls insulated, up to 20% of your heating could still be lost through your floor. As with other types of insulation, you could be eligible for a free underfloor insulation grant through the ECO scheme, if you meet the eligibility criteria. 

Under the ECO scheme, low-income households and those who will struggle with the cost of heating their home could benefit from a free grant which would see free underfloor insulation installed if they qualify and if it is suitable for their home.

Is your property suitable for underfloor insulation?

Modern properties tend to have concrete ground floors that can be insulated by laying insulation on top, but these are not eligible under the scheme.  The funding is available generally for older type properties which are more likely to have a suspended timber floor.

If you have a basement or cellar below your property, then it is likely that you will have a suspended floor, with the floorboards resting over the joists. These types of floors usually lose heat more easily. Air bricks or ventilation bricks are another indication that you likely have a suspended floor that would benefit from underfloor insulation.

When your home is being insulated from underneath, the mineral fibre is rolled out and secured with netting that is stapled between the floor joists. Another modern alternative is the use of spray foam being applied to the underside of your floorboards.

What type of floor do you have?

You can determine your floor type by taking a look, either from a basement or cellar, or by lifting a corner of any carpet and underlay. If you have a suspended wooden floor, you will be able probably be able to see the joists and bottom of the floorboards from the basement. 

Why apply for underfloor insulation?

  • If you qualify for the scheme’s underfloor heating grants you could get free insulation.
  • You can benefit from sizeable reductions in your heating bills when you get underfloor insulation.
  • Enjoy a more comfortable home without worrying about how much you’re spending on heating.
  • Increase the re-sale value of your home.
  • Make the most of the grants while they are available.

Who can qualify for underfloor insulation grants?

If your house was constructed after the 1980s the likelihood is that you won’t be eligible for underfloor insulation as they are normally built with concrete floors rather than timber. You could qualify if you have a basement, cellar, or property that is built on a slope. 

You could qualify if your household income is £31,000 or less, or if your property is in receipt of a qualifying benefit in order to get access to an insulation grant for free underfloor insulation. These benefits include:

  • Income-based Jobseekers Allowance (JSA)
  • Income-related Employment & Support Allowance (ESA)
  • Income Support (IS) 
  • Pension Credit Guarantee Credit 
  • Working Tax Credit (WTC)
  • Child Tax Credits (CTC)
  • Universal Credit (UC) 
  • Housing Benefit (new eligible benefit under ECO4)
  • Pension Credit Savings Credit (new eligible benefit under ECO4)
 

As well as being in receipt of a benefit, you need to be the homeowner occupying the property and your home should be situated in England, Scotland, or Wales, and be heated by gas. If you have had your ground floor insulated previously, you could be eligible to have it updated to the latest standards, but one of our professionals can advise on this.

Complying with building regulations

Any floor insulation work we carry out at your property will fully comply with the appropriate building regulations for where you live. Properties in England and Wales, for example, the floor should have a U-value of 0.25 W/m2K – this is a measure of how quickly heat will travel through the floor.

In order to reach this standard, this usually requires a minimum of 70mm of high-performance foam insulation, or 150mm of mineral wool, but this will vary based from property to property.
