Loft Insulation & Lighting
Roughly a quarter of the heat lost from an uninsulated home goes through the roof. If your loft has thin, old or squashed insulation, it is the cheapest heat-loss problem in the house to fix — and the natural time to do it is while the floor is up anyway.
In short — what loft insulation is
Loft insulation work covers topping up, replacing or re-lofting the mineral wool across a loft floor so it reaches the depth current Building Regulations expect, which is around 270–300mm. Older homes are frequently found with 100mm or less, or with insulation flattened by years of storage, and both leave a significant amount of heat escaping through the ceiling. Xtraspace Lofts removes old insulation, lays new to full depth and fits a raised floor over the top so it is never compressed again, across Rainham, Medway and Kent. Loft lighting and tidy cabling can be fitted during the same visit.
What customers say
“Colin and his team recently installed boarding in our loft as well as loft ladder of our new build. They were courteous, quick, professional and very tidy. I was kept informed all along the process and the work was done to a very high standard. I thoroughly recommend anyone else to utilise this firm.”
“Really happy with our loft installation from Xtraspace Loft Boarding. Colin was professional, friendly and efficient, and the work was completed to a really high standard. We had our hatch enlarged with an easy to use wooden ladder fitted and the loft boarded with additionally shelving. Great service from start to finish - highly recommend!”
“Great service from start to finish, and not a spec of dirt in sight. Everything exactly as discussed and would recommend to anyone with a new build, especially if you have concerns around warranty etc. These guys really know their stuff, and we have so much more room in our house now!”
What we usually find
Homes insulated before the mid-2000s often have 100mm or less, laid once and never touched. Homes where the loft has been used for storage have insulation crushed flat under boards or boxes, which is not much better than having none in that area.
Either way the fix is the same: lift out what's there, lay new mineral wool to current depth across the whole floor, and then keep it that way with a raised floor rather than putting boards straight back on top of it.
Insulation and boarding belong in the same job
Doing the two separately means paying twice to get into the same space. Doing them together means the insulation goes in at full depth, the raised frame goes on above it, and neither ever compromises the other.
It also means the parts of the loft nobody can reach once the floor is down — the eaves, the corners behind the trusses — get done properly while there's still access to them.
Lighting while we're up there
A loft with no light is a loft you use with a phone torch in your teeth. We fit loft lighting and run the cabling tidily, clipped and clear of the boards, so nothing is trapped under the floor.
It costs very little on top of a boarding job and it is consistently the thing customers say they should have done sooner.
Hatch too small or draughty?
Insulated loft hatch, fitted the same visit
We widen the opening and fit a new insulated hatch door that seals against draughts, usually alongside the ladder or boarding. £150–£350 fitted.

Frequently asked questions
Current Building Regulations point to around 270–300mm of mineral wool across the loft floor. Many older homes have 100mm or less, and many lofts used for storage have insulation crushed flat under boards, which loses a large share of its performance.
Yes, and it is the sensible way round. We lay the insulation to full depth first, then fit a raised floor above it so the boards never touch it. Doing both in one visit costs less than two separate jobs and means the eaves get done while there is still access.
Yes. We fit loft lighting and run the cabling tidily, clipped and clear of the boards so nothing is trapped under the floor. It is a small addition to a boarding job and one customers consistently say they should have done sooner.
