Underfloor Insulation
For sustainable, cosy homes
Are you tired of cold, draughty floors? Underfloor insulation can fix the problem, as it is designed to stop heat from escaping through the floor of your home.
It not only keeps your floor warmer but also prevents the heat from escaping, eliminates draughts, and makes your living spaces cosier.


The Benefits
Part of the heat pump will live outside of your house. This part often looks like a slightly larger air conditioning unit that you might see on buildings when you go abroad. They typically sit on the ground and will often be attached to one of your exterior walls.
Insulating your floor is a crucial step in creating a fully-insulated, energy-efficient home with several key benefits:
Improved Comfort: It creates a noticeable difference in the overall warmth of your home, not just in the temperature of the floors.
Lower Energy Bills: By preventing up to 10-20% of heat from escaping through the floor, you'll need to use less energy to heat your home.
Reduced draughts: Underfloor insulation also helps to draught-proof your home, sealing up gaps in suspended floors.
Environmental Impact: Consuming less energy for heating means you’ll also reduce your home's carbon footprint.
Government Grants Available: You may be eligible for grants to help cover the cost of installation, making the upgrade even more cost-effective.

How It Fits in Your Home
How It Fits in Your Home
Underfloor insulation is suitable for both suspended and solid floors on the ground level of most homes.
Suspended Floors: This process is more straightforward as our team works underneath your existing floorboards. It can also be an ideal time to draught-proof your home where the floor meets the walls.
Solid Floors: This method is more involved as it may require building work. Our advisers will assess your home to determine the best approach, whether it's laying insulation on top of the existing floor or undertaking a more comprehensive rebuild.

Installing underfloor insulation can save you a lot of CO2 each year. For a three-bedroom semi-detached home, it could save 190 kg of CO2 each year. That’s about the same amount of CO2 that the average UK household produces using electricity every month.

Two-bedroom terraced house | 120 kg |
Three-bedroom semi-detached | 190 kg |

Is underfloor insulation right for my house?
Underfloor insulation is suitable for most homes in York and it works especially well in bungalows. It can be added to suspended timber floors and solid concrete floors. This helps to keep your home warmer by stopping heat from escaping through the floor. If you have high heating bills, underfloor insulation could be a great solution.
Approximate cost saving:
Savings will depend on the size of your home, the type of floor you have and your energy prices. A three-bedroom semi-detached home could save around £60 each year, while a four-bedroom detached could save up to £100 each year.
(Energy Saving Trust. Based on July 2024 fuel prices).
The cost to install underfloor insulation can vary and is based on a few factors:
The size of your home.
The materials used.
Whether you have a suspended or solid floor.
Access to the underside of the floorboards
Here’s an example of how much it might cost:
Type of home | Cost for underfloor insulation |
One-bedroom flat | £450 to 700 |
Two-bedroom terraced | £800 to £1200 |
Three-bedroom semi-detached | £1,200 to £1,750 |

(Based on January 2024 prices).
How does Underfloor insulation work?
Underfloor insulation works by adding special materials on or under your floor, like fluffy wool or foam panels. These materials stop heat from escaping through the floor. You can't see the insulation because it's hidden under your floorboards or solid floor, so your home looks just the same.
