Loft insulation for top-floor flats and maisonettes
If you live in a top-floor flat or maisonette, the loft above may not be yours. Insulating it is often possible, but you will need the right permission first.

| You may need | Written consent from the freeholder or management company |
| Watch for | Shared lofts, fire-separation walls, access |
Check who owns the loft
In a leasehold flat, the roof and the space under it usually belong to the freeholder, not to the flat below. Your lease says what is included in your flat and what you need permission for. If the loft isn’t part of your lease, you will need written consent from the freeholder or management company before any work.
Shared lofts
In converted houses and some purpose-built blocks, one loft runs over several flats. Insulating just your part can still help you, but it is often better done for the whole roof at once, by agreement. Fire-separating walls in the loft must not be damaged or bridged.
Access
The hatch to a shared loft is sometimes in a communal hallway or in another flat. We will need a way in, which may mean arranging it through the freeholder.
Tell us in your enquiry that you are in a flat, and what you know about ownership. It helps us quote properly.
