SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Kingsbury loft has already been converted, insulation has to follow the rafters rather than the floor. SuperQuilt does that in 40mm instead of the 200mm-plus a wool build-up would need.

Loft insulation in Kingsbury
Roughly a quarter of an uninsulated home's heat escapes through the roof. For Kingsbury homeowners that is the cheapest problem in the house to fix, and the one most likely to have been fixed badly the first time. We do it properly.

None of this requires permissions, scaffolding or structural work. In Kingsbury, as anywhere, it is a day's work with materials that cost little relative to what they save.
Kingsbury's homes
What we find in Kingsbury roof spaces
The roofs over Kingsbury are mostly generous pitched roofs on the interwar stock, many with hipped ends and a central water tank, and they were built during the 1890s through the 1930s for a housing market with no expectation of thermal performance. Insulation arrived later, retrofitted into spaces never designed to accommodate it, and the results vary enormously from street to street.
On survey we routinely find the same handful of problems: material compressed to a fraction of its depth by boards laid straight onto the joists, insulation packed hard into the eaves and sealing off the roof's only ventilation path, hatches left as bare uninsulated panels, and recessed downlighters buried under wool. None of these are exotic and all of them are fixable — but they need finding first.
The interwar semis typically have large, square, walkable lofts — the best candidates in london for boarding as proper storage, which is one more reason we measure rather than assume.

Five ways we keep Kingsbury homes warm
Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.
Loft insulation installation
270mm depthTopping up from the 100mm many Kingsbury houses still have to a full 270mm is the cheapest meaningful energy improvement available to a UK homeowner.
Loft boarding
Storage-readyStorage that does not flatten your insulation. We raise the deck on battens so the full depth survives underneath — the version most Kingsbury lofts should have had first time.
Loft ladders
Fitted in a dayFitted in a day, finished to match your landing, with the hatch insulated and draught-sealed as part of the same job.
Loft makeovers
All-in-oneOne team, one survey, one sequence of work. The insulation depth sets the batten height, the batten height sets the ladder landing — which is why doing it piecemeal costs more.

Questions & answers
Kingsbury loft insulation — common questions
What happens to the water tank and pipes?
Insulating the loft floor makes everything above it colder, including your tank and pipework. Lagging is therefore part of the work rather than an optional extra, and we will point out anything that looks like it will need attention.
Can I still use my Kingsbury loft for storage afterwards?
Absolutely. The only wrong way to do it is to board flat onto the joists. We raise the deck on battens or loft legs, board it in tongue-and-groove panels and leave the eaves clear so the roof keeps ventilating.
Will this improve my EPC rating?
It is one of the most reliable ways to improve a rating, because depth is a direct input rather than an inferred assumption. How far it moves depends on everything else about the Kingsbury property, but the direction is not in doubt.
How long does the work take in a typical Kingsbury home?
Most Kingsbury lofts are insulated to full depth in half a day. Adding raised boarding takes it to a full day, and fitting a ladder at the same time adds a couple of hours. We give you the expected duration with the quote, not on the morning.
Will insulating my loft cause damp?
Not if it is done properly. Insulating the floor makes the roof space colder, so moisture condenses more readily — the defence is the ventilation path at the eaves. Blocking it with insulation is what creates damp lofts. We keep it clear on every job. Our ventilation guide explains the mechanism.
Can you fit a loft ladder at the same time?
Certainly. Doing the ladder in the same visit means the boarding is planned around where the ladder lands, which is considerably better than retrofitting one to a deck that was not designed for it.
