SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Mitcham 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 Mitcham

Why it matters
The case for insulating your Mitcham 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

90%less radiant heat loss with SuperQuilt multifoil
Put against current energy prices, a Mitcham loft still carrying 100mm of settled wool is costing its owner money every single winter it stays that way.
Mitcham's homes
Why Mitcham houses lose more heat than they should
Most of Mitcham was built during the 1860s through the 1930s, and its roofs are typically slate and tile pitched roofs, with many terraces running unbroken for a considerable length. 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 subdivision into flats is very common, so ownership of the roof space is worth establishing before work is booked.
Our services in Mitcham
Five ways we keep Mitcham 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 Mitcham homes this is the single highest-value thing you can do to the building.
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 Mitcham footprint.
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-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
Mitcham loft insulation — common questions
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.
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.
Will this improve my EPC rating?
Usually, and often noticeably. Loft insulation depth is recorded directly by the assessor, so increasing it from 100mm to 270mm generally moves the rating. We hand over product documentation and declared performance figures so your assessor records what is actually there.
Do you work in the streets around Mitcham?
Yes — we cover Mitcham 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.
What happens to the water tank and pipes?
They end up above the new insulation line, in a colder space than before, so they must be lagged. The cold water tank is insulated on its sides and lid but never underneath — the warmth rising from the house is what keeps it from freezing. We handle this as part of the job.
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.
