SuperQuilt multifoil insulation
A/A+ fire ratedWhere a West Norwood 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.

Put against current energy prices, a West Norwood loft still carrying 100mm of settled wool is costing its owner money every single winter it stays that way.
West Norwood's homes
West Norwood: what a survey usually turns up
Housing across West Norwood and the surrounding South London area is largely dense Victorian terraces and villas, interwar semis and a substantial amount of purpose-built and converted flats, built through the 1860s 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 — subdivision into flats is very common, so ownership of the roof space is worth establishing before work is booked — and you have most of what a West Norwood survey is checking for.

Five ways we keep West Norwood 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 West Norwood 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 West Norwood 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 West Norwood home actually has.
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
West Norwood loft insulation — common questions
Will insulating my loft cause damp?
Correctly installed, no. The risk comes from packing material hard into the eaves and sealing off the airflow the roof depends on. We stop the insulation short and use eaves trays where the pitch requires them.
Do you offer free surveys in West Norwood?
Yes. Every enquiry from West Norwood and the surrounding area starts with a free, no-obligation visit. We measure the loft, check the joists and ventilation, and write a fixed price afterwards. There is no call-out charge whether you proceed or not.
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 I still use my West Norwood loft for storage afterwards?
You can, and most West Norwood customers do — but the deck has to sit above the insulation, not on it. That is the whole reason raised boarding exists. Tell us at survey stage if storage matters to you, because it changes how the insulation is planned.
Do I need planning permission in West Norwood?
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.
How long does the work take in a typical West Norwood home?
Most West Norwood lofts are insulated to full depth in half a day. Adding raised boarding takes it to a full day, and fitting a ladder at the same time adds a couple of hours. We give you the expected duration with the quote, not on the morning.
