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

Loft insulation in Brockley
Roughly a quarter of an uninsulated home's heat escapes through the roof. For Brockley homeowners that is the cheapest problem in the house to fix, and the one most likely to have been fixed badly the first time. We do it properly.

Why it matters
The case for insulating your Brockley 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 Brockley house is the cheapest part of it to improve, and the part losing the most.
Brockley's homes
Why Brockley lofts need attention
Brockley forms part of South East London, an area whose housing is characterised by Victorian and Edwardian terraces on the older high ground, extensive interwar semi-detached suburbs, and post-war estates. The bulk of it went up during the 1880s through the 1930s, decades before insulation was a design consideration at all, and what sits above the ceilings today is usually a retrofit added at some point in the last fifty years to whatever standard was current at the time.
That matters because the standard has moved repeatedly. Lofts insulated in the 1980s typically received 100mm; earlier work was often 50mm or nothing. Current guidance is 270mm. A great many Brockley houses therefore contain insulation that was entirely adequate when it was fitted and is now doing roughly a third of the work it should be — while the homeowner reasonably assumes the loft is 'done'.
Hipped roofs on 1930s semis cut the usable loft area down sharply at the corners, which changes how much of it is worth boarding. It is the sort of thing a survey establishes in ten minutes and a phone quote never can.

Five ways we keep Brockley 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 depthMineral wool cross-laid to the 270mm depth current regulations recommend. For most Brockley homes this is the single highest-value thing you can do to the building.
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 Brockley lofts should have had first time.
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 Brockley home actually has.
Loft makeovers
All-in-oneInsulation, boarding, lighting and a ladder handled together in one visit — cheaper and better sequenced than buying the four separately.

Questions & answers
Brockley loft insulation — common questions
How long does the work take in a typical Brockley home?
A straightforward insulation job in a three-bedroom Brockley 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?
270mm of mineral wool, cross-laid — the depth current building regulations guidance points to for a cold loft. Where a Brockley property has a room in the roof and depth is constrained, we use 40mm multifoil at rafter level instead.
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 Brockley loft is established at survey and priced separately.
What happens to the water tank and pipes?
Pipes get lagged and the tank gets insulated on the sides and top only. Leaving the base open is deliberate — it is the only thing preventing a frozen tank in a hard winter.
