Loft Insulation available via current grant schemes is made from mineral wool (glass fibre). It is rolled out on the floor of the loft, in between and then across the joists. It works like a blanket by trapping the rising heat in your home.

Did you realise Loft Insulation will help to keep your home cooler in the summer months, by preventing heat coming in through the roof.

The recommended depth for Loft Insulation is 11-12 inches or 270-300mm.

If your loft is insulated, but hasn’t been topped up in the past 15 years, it will most likely benefit from having more installed. The maximum existing insulation must be no deeper than 4 inches or 100mm.

The Energy Company Obligation (ECO) was introduced by the government in January 2013 to reduce the UK’s energy consumption.


Loft Insulation frequently asked questions


How long does Loft Insulation take to install?

An average size loft will take an hour, to an hour and a half to insulate.


How can I tell if my loft already has too much Insulation?

If the Insulation is level with the joists on the floor of the loft (i.e. 4 inches, 100mm or less) you are likely to qualify for a grant to top up the insulation.


What if my loft is boarded?

A small amount of boarding is allowed, but if there is more than 10% you will need to have the boards lifted before the work is carried out.


My hatch is small, Can you still install insulation?

The loft hatch must be 400mm/16″ square


Can you install Loft Insulation if I have a lot of stored items?

Installers can work around a few items, but if there is too much the surveyor may advise you to remove them. Our installers will not be able to do this.


Do Loft Insulation Grants cover the sloping part of the roof?

No. This Grant scheme only covers Insulation rolled out in blankets on the floor of the loft, between and then across the joists.
