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

Loft insulation in Hammersmith
Hammersmith sits in West London, where the housing is dominated by Victorian terraces, large Edwardian villas, extensive interwar suburban development and post-war blocks. Much of it was insulated to a standard that has since been superseded twice over. We put that right — properly, in a day, for a price agreed in advance.

Why it matters
The case for insulating your Hammersmith 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 Hammersmith property it is the largest single heat loss and the smallest single bill to fix it.
Hammersmith's homes
Older Hammersmith homes, modern standards
Hammersmith'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 Hammersmith survey.

Five ways we keep Hammersmith 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 Hammersmith loft actually performs.
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 Hammersmith lofts should have had first time.
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 Hammersmith homeowners who want the roof space to stop being a problem and start being storage: everything, in a day.

Questions & answers
Hammersmith loft insulation — common questions
Do you work in the streets around Hammersmith?
Yes. Hammersmith is well within our regular working area, along with everywhere immediately around it — see the full list of areas.
What insulation depth do you fit?
Full recommended depth of 270mm as standard. Going deeper gives sharply diminishing returns; stopping short leaves money on the table every winter. For sloping ceilings in Hammersmith loft rooms, multifoil at around 40mm is the practical alternative.
Can you fit a loft ladder at the same time?
We fit ladders alongside insulation and boarding routinely — it is one of the main reasons the combined makeover works out cheaper than booking the elements separately.
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.
How long does the work take in a typical Hammersmith home?
Most Hammersmith 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 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 Hammersmith property, but the direction is not in doubt.
