Loft insulation in Kingston upon Thames
If your Kingston upon Thames loft has 100mm of flattened wool and a boarded patch balanced on the joists, you are not alone and you are losing money every winter. We fit insulation to the recommended 270mm depth, and raise any boarding clear so it keeps working.

Why it matters
The case for insulating your Kingston upon Thames loft
25%of a home's heat is lost through an uninsulated roof

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 Kingston upon Thames property it is the largest single heat loss and the smallest single bill to fix it.

Heat loss in Kingston upon Thames: where it goes
In a typical Kingston upon Thames 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.

Questions & answers
Kingston upon Thames loft insulation — common questions
How much does loft insulation cost in Kingston upon Thames?
Price depends on the loft's floor area, the depth and condition of anything already up there, how easy the space is to move around in, and whether old material has to be removed. That is why every Kingston upon Thames quote follows a free survey rather than a phone call. Once given, the price is fixed. Our cost guide sets out each variable.
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 Kingston upon Thames loft is established at survey and priced separately.
Do I need planning permission in Kingston upon Thames?
Not for insulation, boarding or a ladder. The line falls at conversion — turning the loft into a habitable room — which is a structural job requiring building control sign-off and a different trade entirely.
Do you work in the streets around Kingston upon Thames?
Yes — we cover Kingston upon Thames 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 insulation depth do you fit?
The recommended 270mm, achieved in two layers: the first between the joists, the second laid across them to eliminate the cold bridge through the timber. Skipping that second cross-lay is one of the most common shortcuts in the trade.
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.
