SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Upper Holloway 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.

Why it matters
The case for insulating your Upper Holloway loft
25%of a home's heat is lost through an uninsulated roof
1 in 5UK lofts are under-insulated or have the wrong material
270mmthe depth current building regulations recommend
90%less radiant heat loss with SuperQuilt multifoil
The reason we lead with the roof rather than the walls or the windows is arithmetic: in a typical Upper Holloway property it is the largest single heat loss and the smallest single bill to fix it.
Upper Holloway's homes
Why Upper Holloway houses lose more heat than they should
Most of Upper Holloway was built during the 1870s through the 1930s, and its roofs are typically steeply pitched slate and clay tile roofs with usable, walkable voids above the top floor. Nothing about that construction is defective — these are, for the most part, sound, well-built houses. They were simply designed for a world where heating was cheap and thermal performance was not something anyone measured.
Bolting modern expectations onto that fabric is largely a matter of doing a few things properly rather than doing many things at all. Full-depth insulation at ceiling level, a ventilation path that has not been blocked, a hatch that is sealed rather than left as a hole, and boarding that sits above the wool instead of on top of it. Get those four right and the loft stops being the weak point.
Bear in mind too that many of the larger houses were divided into flats decades ago, so the loft often sits above a top-floor conversion with its own separate access.

Five ways we keep Upper Holloway 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 Upper Holloway loft actually performs.
Loft boarding
Storage-readyTongue-and-groove panels, screwed rather than nailed so they lift again if a cable needs reaching — raised clear of the insulation throughout.
Loft ladders
Fitted in a dayMany older Upper Holloway hatches are too small for a ladder to swing through safely. We measure at survey and price any enlargement up front rather than on the day.
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
Upper Holloway loft insulation — common questions
Do you work in the streets around Upper Holloway?
Yes. Upper Holloway is well within our regular working area, along with everywhere immediately around it — see the full list of areas.
How much does loft insulation cost in Upper Holloway?
There is no single figure, and anyone offering one for Upper Holloway without seeing the loft is guessing. The largest swing factor is almost always whether the existing material can be topped over or has to be stripped out and disposed of. We survey free of charge and quote a fixed price afterwards.
Can I still use my Upper Holloway loft for storage afterwards?
Yes, provided the boarding is raised. Screwing boards straight onto 100mm joists over 270mm of wool compresses it to a third of its depth and throws away most of what you paid for. We fit raised boarding on battens so the insulation stays at full depth underneath.
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.
