Shortly due to get a green survey - but the loft has been converted.

I had a crawl around yesterday and the bigger areas have insulation. But running along the length of the house is a crawl space, which has very little insulation (not sure why I didn't check before).

By the looks of it there isn't much between floors either.

So I guess I need to leave breathing space at the edges of the roof for circulation. But how do I deal with the fact the wiring up there runs over the beams without any slack to move it out of the way?

Advice seems to be not to cover it...

Also any good products I could push between the floors to help?

75mm gap from the felt should be more than enough. As regards to cables its only 32amp shower and cooker cables that are really an issue, also what out for cables that power Immersion heaters, they can be quite small easy to miss. Earthwool insulation is the best stuff I think for the job, reasonably cheap, and non itch and bloody effective.


I used to insulate lofts for a living for 5 years.

All the houses I've had have had the wiring under the insulation.

As long as it's not polystyrene there shouldn't be an issue - it should all be suitably rated.
