What is loft insulation?

Loft insulation is a simple and effective way to improve the energy efficiency of your home and lower your bills. Materials used for loft insulation are typically glass fibre or renewable wood fibre, which when installed into your loft space, prevent heat from escaping.

Loft insulation can be installed between the joists of your loft floor or in between the rafters that support the roof.

How do I know if I need loft insulation?

If you have easy access to your loft then take a look at the current floor space of your loft, between the rafters or joists. If there is a thick layer of insulation between 270mm and 300mm in situ it may be that loft insulation has already been installed.

Loft Insulation FAQ’s

Can my loft be used for storage after being insulated?

You can’t compress the loft insulation as this will cause it to lose its thermal qualities. You would need to ensure that any storage does not sit directly on top of the insulation.

Does my loft need to be empty to complete the insulation process?

For the installation of loft insulation you will need to remove any personal belongings from this space.

Is there such a thing as too much loft insulation?

Yes. The ideal amount of insulation is 270-300mm deep. This will also ensure there is adequate ventilation. If you install too much loft insulation you could encourage condensation which could lead to mould.

Do I need to remove old loft insulation before adding new?

We don’t recommend you take on the task of removing existing insulation. Your loft insulation experts will remove any insulation that may not be fit for purpose, or top up with new additional insulation.

How do I insulate a loft conversion?

If your loft is also a living space, you will need to insulate the inside of your roof rather than your loft floor. Roof insulation is more costly to install than loft insulation, however it will save money on your fuel bills.

How long does loft insulation last for?

Loft insulation will last indefinitely and will save you money on your heating bills by keeping your loft area warm and cosy throughout the year.

How long does it take to install loft insulation?

Installing loft insulation is generally a quick and effective process, taking between 1- 3 hours providing all personal belongings have been removed before the installer arrives.

Residential Energy Services will then work with you to select the best energy-saving strategies for your home. We also collaborate with a trusted network of partners to verify that such measures are implemented correctly.

The Energy Company Obligation is a government programme in which energy companies support energy efficiency solutions for your house that are installed by approved licenced installers.
