Loft insulation in Belsize Park
If your Belsize Park 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 Belsize Park 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 Belsize Park house is the cheapest part of it to improve, and the part losing the most.
Belsize Park's homes
Belsize Park: what a survey usually turns up
Housing across Belsize Park and the surrounding North West London area is largely Victorian and Edwardian terraces close in, and mile after mile of interwar semi-detached and detached suburbia further out, built through the 1890s through the 1930s. When we open a hatch here, the most common finding is not an absence of insulation but an insufficiency of it — a layer that was correct when fitted and has since been overtaken by both the guidance and the price of energy.
The second most common finding is a ventilation problem. Insulating a loft floor makes the roof space colder, and a colder roof space condenses more readily. Where a previous installer packed material tight into the eaves, the roof has lost the airflow it depends on and the homeowner has a damp loft they blame on the insulation rather than on the installation.
Add to that the local factor — the interwar semis typically have large, square, walkable lofts — the best candidates in London for boarding as proper storage — and you have most of what a Belsize Park survey is checking for.

Five ways we keep Belsize Park 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 depthTopping up from the 100mm many Belsize Park houses still have to a full 270mm is the cheapest meaningful energy improvement available to a UK homeowner.
Loft boarding
Storage-readyBoards laid straight onto joists crush 270mm into 100mm. We batten out instead, so Belsize Park homeowners get usable storage and keep the insulation they paid for.
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 Belsize Park home actually has.
Loft makeovers
All-in-oneFor Belsize Park homeowners who want the roof space to stop being a problem and start being storage: everything, in a day.

Questions & answers
Belsize Park loft insulation — common questions
Do you work in the streets around Belsize Park?
Yes — we cover Belsize Park 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.
Do you offer free surveys in Belsize Park?
Free, with no call-out fee and no pressure. A meaningful proportion of our Belsize Park surveys conclude that the loft is already adequately insulated and the homeowner should keep their money — which is a perfectly normal outcome.
How long does the work take in a typical Belsize Park home?
Half a day for insulation alone; a full day for a combined job with boarding, lighting and a ladder. Very large Belsize Park lofts or heavy strip-outs occasionally run into a second morning, and we tell you that in advance.
