SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Hendon 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 Hendon
Cold upstairs rooms and a heating bill that keeps climbing usually have the same cause, and in Hendon it is very often the roof. We survey the loft free of charge, measure what is genuinely up there, and quote a fixed price to bring it up to standard.

Put against current energy prices, a Hendon loft still carrying 100mm of settled wool is costing its owner money every single winter it stays that way.
Hendon's homes
Hendon: what a survey usually turns up
Housing across Hendon and the surrounding North West London area is largely Victorian and Edwardian terraces close in, and mile after mile of interwar semi-detached and detached suburbia further out, built through the 1890s through the 1930s. When we open a hatch here, the most common finding is not an absence of insulation but an insufficiency of it — a layer that was correct when fitted and has since been overtaken by both the guidance and the price of energy.
The second most common finding is a ventilation problem. Insulating a loft floor makes the roof space colder, and a colder roof space condenses more readily. Where a previous installer packed material tight into the eaves, the roof has lost the airflow it depends on and the homeowner has a damp loft they blame on the insulation rather than on the installation.
Add to that the local factor — the interwar semis typically have large, square, walkable lofts — the best candidates in London for boarding as proper storage — and you have most of what a Hendon survey is checking for.

Five ways we keep Hendon 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 depthFull-depth mineral wool, fitted with the ventilation path protected and the hatch sealed — the details that decide whether a Hendon loft actually performs.
Loft boarding
Storage-readyA squared, edged deck reached from the hatch, with the eaves left open so the roof keeps breathing. Sized to what you will actually use rather than the whole Hendon footprint.
Loft ladders
Fitted in a dayThe thing that turns a loft you avoid into one you use. Grab rails and a boarded landing area where the design allows.
Loft makeovers
All-in-oneFor Hendon homeowners who want the roof space to stop being a problem and start being storage: everything, in a day.

Questions & answers
Hendon loft insulation — common questions
How long does the work take in a typical Hendon home?
A straightforward insulation job in a three-bedroom Hendon property is a half-day. Larger, cluttered or awkward-access lofts take longer, and stripping out failed material adds time — all of which is established at survey and reflected in the quote.
What insulation depth do you fit?
The recommended 270mm, achieved in two layers: the first between the joists, the second laid across them to eliminate the cold bridge through the timber. Skipping that second cross-lay is one of the most common shortcuts in the trade.
Do you remove the old insulation?
Only when it needs to go. Sound, dry wool can be topped over, which saves you the removal cost. Material that is damp, vermin-fouled or collapsed does come out, and we bag it and take it away. Which applies to your Hendon loft is established at survey and priced separately.
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.
