What is loft insulation?

We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.

Questions about loft insulation in Gloucestershire

How do I book a survey in Gloucestershire?

Send the form or call us. We call back to agree a time and confirm it in writing.

Which council covers my address in Gloucestershire?

Councils in Gloucestershire include Gloucestershire and South Gloucestershire. Your council matters for building control questions and some funding schemes.

Can you insulate around downlights?

Recessed downlights need clearance or a fire-rated cover so they do not overheat. We fit covers where needed and leave a clear zone around fittings that cannot be covered.

Does loft insulation need building control approval?

On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.
