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

Loft insulation in Teddington
Teddington sits in South West London, where the housing is dominated by substantial Victorian and Edwardian houses, interwar semis and detached homes, and a large number of period conversions. Much of it was insulated to a standard that has since been superseded twice over.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 Teddington 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 Teddington property it is the largest single heat loss and the smallest single bill to fix it.
Teddington's homes
Heat loss in Teddington: where it goes
In a typical Teddington property built during the 1880s through the 1930s, the roof accounts for the largest single share of heat loss of any element in the building envelope. Warm air rises, the ceiling is thin, and above it sits a ventilated void at close to outdoor temperature for most of the winter.
The good news is that this is the cheapest part of the fabric to improve, by a long way. Wall insulation is disruptive and expensive. Window replacement is a major capital cost. Loft insulation is a day's work with materials that cost very little relative to what they save, and it needs no permissions of any kind.
The one local caveat: a high proportion of lofts here have already been converted or partly converted, which moves the insulation from the floor to the rafters. We factor that in at survey stage.
Our services in Teddington
Five ways we keep Teddington 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 Teddington 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 Teddington lofts should have had first time.
Loft ladders
Fitted in a dayFitted in a day, finished to match your landing, with the hatch insulated and draught-sealed as part of the same job.
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
Teddington loft insulation — common questions
How much does loft insulation cost in Teddington?
We price Teddington jobs after a free survey, itemised so you can see what the insulation, any boarding and any removal each cost. There is no call-out charge and the figure does not move once it is written. The London cost guide explains what drives it.
Will insulating my loft cause damp?
It can if the ventilation is ignored, which is why we check it before anything comes off the van. If we find an existing condensation problem in a Teddington loft, we deal with the cause first rather than insulating over it.
