A/A+ fire ratedMultifoil earns its place in Southall roofs where depth is the binding constraint — period timbers, low headroom, or a conversion already boarded out.

Why it matters
The case for insulating your Southall 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
Those figures are national, but the logic is entirely local: the roof over a Southall house is the cheapest part of it to improve, and the part losing the most.
Southall's homes
Older Southall homes, modern standards
Southall'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 Southall survey.
Our services in Southall
Five ways we keep Southall 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 depthThe standard job, done to standard: two layers, the second laid across the joists to kill the cold bridge, eaves left clear. Most Southall lofts are finished in half a day.
Loft boarding
Storage-readyBoards laid straight onto joists crush 270mm into 100mm. We batten out instead, so Southall homeowners get usable storage and keep the insulation they paid for.
Loft ladders
Fitted in a dayFixed, stable access instead of a stepladder on the landing. Timber, aluminium or concertina, chosen to suit the space your Southall home actually has.
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.

Where we work
Covering Southall and the surrounding area
Ealing and Hounslow are all covered by the team that works Southall, which is why we can usually offer a survey slot within the same week rather than the same month.

Questions & answers
Southall loft insulation — common questions
Can I still use my Southall 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.
How long does the work take in a typical Southall home?
Most Southall 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.
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.
Do you work in the streets around Southall?
Yes — we cover Southall and the whole surrounding area, and our teams are usually working somewhere nearby on any given week. If your street is not obviously listed on our coverage page, ring us anyway; the list is not exhaustive.
Do you remove the old insulation?
Where it can stay, it stays and we top over it. Where it cannot, it goes and the disposal is included in the fixed price. You will never find out about removal costs mid-job — that is decided at survey.
Do you offer free surveys in Southall?
Free, with no call-out fee and no pressure. A meaningful proportion of our Southall surveys conclude that the loft is already adequately insulated and the homeowner should keep their money — which is a perfectly normal outcome.
