Underfloor insulation – stop heat escaping, prevent draughts.

If you want a warmer home, floor insulation can make a big difference while cutting energy costs and saving you money.

Installing it involves adding an insulating material beneath your floorboards and/or concrete floor at ground level, stopping heat escaping as well as preventing draughts.

  • How much money will I save?

    Floor insulation is well worth doing when combined with other types of insulation. You can make a yearly heating bill saving of up to £65.

  • What is underfloor insulation?

    We insulate floors by adding an insulating material beneath the floorboards or concrete floor, which reduces heat escaping through the floor into the ground or cellar below. Around 15% of heat is lost from a house through the floor.

    Insulation is also excellent for preventing draughts coming up through the floorboards.

  • How long does it last?

    All insulation installs come with a 25-year CIGA guarantee.

  • What's the process?

    If your property has a suspended wooden floor, then we will wrap insulation material around all the joists, and generally make sure that the gap is filled.

    If it's a concrete floor, we will cover the cellar in as many layers of insulation material as have been deemed appropriate at survey.

  • How long does it take?

    While it can vary depending on the size of the property, on average the process takes a few hours to complete, including clearing up afterwards.

  • What type of underfloor insulation do you use?

    We use a type of mineral wool insulation attached to a high performance vapour permeable membrane with overlapping tabs for secure and safe fixing to the floor joists.

    The high tensile strength of the membrane keeps the insulation firmly in position with no sagging, and has the added benefit of retaining any loose fibres. This is a much safer and better way of installing in confined spaces than traditional netting.

  • What expertise does Baxter Kelly have?

    All of our technicians are fully qualified and accredited. We’re available to answer any questions you may have.

How much does underfloor insulation cost?

Work conducted under the ECO or ECO Flex schemes come at zero cost to the customer. The price of any work conducted outside these schemes is dependent on the size of the property and location, among other factors.  Finance available. Get a real-time quote below.

Underfloor Insulation

What type of floor do I have, and do I need to insulate it?

You may be wondering if underfloor insulation is a worthwhile investment – after all, there’s no point if you don’t need it, or if it’s unsuitable for your home.

Your need for floor insulation depends on what kind of floors your home has:

  • Houses with suspended floors built pre 1930s are more likely to lose heat through the floor, as they’re effectively suspended above a gap.
  • Homes built post 1930s tend to be built with concrete floors, and so have less of a problem. However concrete floor insulation will still save you money on your heating bill. Normally this involves insulating the cellar underneath, or adding a layer of solid insulation directly on the floor.
  • If you have a modern home, they are normally built with polystyrene insulation just below the concrete floor surface. If so, underfloor insulation is probably not something your home requires.
