Loft Insulation
A warmer home starts from the top
Loft insulation is one of the simplest and most effective ways to stop heat escaping from your home. It helps you stay warmer for longer and brings your energy bills down—especially in the colder months.
And the best part? You could get your loft insulation fully funded through a government-backed scheme.
- Reduces heat loss
- Lowers your energy bills
- Lasts for decades
- Quick and easy to install
What is loft insulation?
Loft insulation is a layer of material that sits between the joists or rafters in your roof space. It slows down the transfer of heat, keeping more warmth inside your home.
Without it, around a quarter of the heat in your home can be lost through the roof. That means more energy used, higher bills, and a chillier home.
Loft insulation works in all seasons. It keeps heat in during winter and helps keep your home cooler in summer.
It’s a small change with a big impact.
What are the benefits of loft insulation?
Lower heating bills
By keeping heat in, you use less energy to stay warm. That means lower energy bills every month.
A more comfortable home
Rooms stay warmer for longer—even when the heating is off.
Better for the planet
Using less energy means fewer carbon emissions. It’s good for your home and the environment.
Long-lasting protection
Once installed, loft insulation can last for 40 years or more with little to no maintenance.
Quick and simple installation
Most lofts can be insulated in just a few hours, with minimal disruption.
