Loft insulation in Camberwell
If your Camberwell 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 Camberwell loft
25%of a home's heat is lost through an uninsulated roof

None of this requires permissions, scaffolding or structural work. In Camberwell, as anywhere, it is a day's work with materials that cost little relative to what they save.
Camberwell's homes
Older Camberwell homes, modern standards
Camberwell's housing stock largely dates from the 1860s through the 1930s, and the roofs above it are typically slate and tile pitched roofs, with many terraces running unbroken for a considerable length. Very little of it was built with any insulation at all; what is there now was added later, and its condition depends entirely on who added it and when.
Retrofitted insulation ages in predictable ways. Mineral wool settles and compresses under its own weight over decades. Anything that has been walked on, stored on or boarded over is thinner than it was. Material that has been repeatedly damp has lost most of its value. And the very oldest loose-fill products are often best removed entirely rather than topped over.
A specific local factor: subdivision into flats is very common, so ownership of the roof space is worth establishing before work is booked. We look for that on every Camberwell survey.

Five ways we keep Camberwell 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 Camberwell loft actually performs.
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 Camberwell footprint.
Loft ladders
Fitted in a dayMany older Camberwell hatches are too small for a ladder to swing through safely. We measure at survey and price any enlargement up front rather than on the day.
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
Camberwell loft insulation — common questions
How long does the work take in a typical Camberwell home?
Most Camberwell 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.
Can I still use my Camberwell loft for storage afterwards?
Yes, provided the boarding is raised. Screwing boards straight onto 100mm joists over 270mm of wool compresses it to a third of its depth and throws away most of what you paid for. We fit raised boarding on battens so the insulation stays at full depth underneath.
Do you offer free surveys in Camberwell?
Always, and there is no charge or obligation attached. A survey takes around half an hour. We would rather spend it establishing what your Camberwell loft actually needs than quote blind and revise the price later.
Do you remove the old insulation?
It depends what is up there. Cross-laying a new layer over sound existing material is both cheaper and perfectly correct. Failed, contaminated or loose-fill material is stripped, bagged and disposed of — slow work, and we show it as its own line on the quote.
Do you work in the streets around Camberwell?
Yes — we cover Camberwell 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.
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.
