SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Brentford 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 Brentford
Cold upstairs rooms and a heating bill that keeps climbing usually have the same cause, and in Brentford 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.

Why it matters
The case for insulating your Brentford 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

None of this requires permissions, scaffolding or structural work. In Brentford, as anywhere, it is a day's work with materials that cost little relative to what they save.
Brentford's homes
Older Brentford homes, modern standards
Brentford's housing stock largely dates from the 1880s through the 1930s, and the roofs above it are typically pitched tile and slate roofs, with hipped ends common on the suburban stock. Very little of it was built with any insulation at all; what is there now was added later, and its condition depends entirely on who added it and when.
Retrofitted insulation ages in predictable ways. Mineral wool settles and compresses under its own weight over decades. Anything that has been walked on, stored on or boarded over is thinner than it was. Material that has been repeatedly damp has lost most of its value. And the very oldest loose-fill products are often best removed entirely rather than topped over.
A specific local factor: the 1930s suburban expansion here produced thousands of near-identical semis, which means the same loft problems repeat street after street. We look for that on every Brentford survey.

Five ways we keep Brentford 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 Brentford 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 Brentford footprint.
Loft ladders
Fitted in a dayMany older Brentford 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-oneFor Brentford homeowners who want the roof space to stop being a problem and start being storage: everything, in a day.

Questions & answers
Brentford 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 you fit a loft ladder at the same time?
Yes, and it is cheaper done together. The one thing to check is the hatch: many older Brentford openings are too small for a ladder to swing through safely, so enlargement may be needed. We measure at survey and price it up front. See loft ladders.
How much does loft insulation cost in Brentford?
There is no single figure, and anyone offering one for Brentford 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.
How long does the work take in a typical Brentford home?
A straightforward insulation job in a three-bedroom Brentford 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.
Do I need planning permission in Brentford?
Not for insulation, boarding or a ladder. The line falls at conversion — turning the loft into a habitable room — which is a structural job requiring building control sign-off and a different trade entirely.
Can I still use my Brentford 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.
