Loft insulation in Dulwich
We insulate lofts across Dulwich — topping up thin or ageing material to the depth current building regulations recommend, boarding the space so it earns its keep, and fitting proper access so you can actually get to it. Every job starts with a free survey, and every price is fixed before work begins.

Why it matters
The case for insulating your Dulwich 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 Dulwich house is the cheapest part of it to improve, and the part losing the most.
Dulwich's homes
Older Dulwich homes, modern standards
Dulwich'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 Dulwich survey.

Five ways we keep Dulwich 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 Dulwich loft actually performs.
Loft boarding
Storage-readyTongue-and-groove panels, screwed rather than nailed so they lift again if a cable needs reaching — raised clear of the insulation throughout.
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-oneInsulation, boarding, lighting and a ladder handled together in one visit — cheaper and better sequenced than buying the four separately.

Questions & answers
Dulwich loft insulation — common questions
Do you work in the streets around Dulwich?
We do. Coverage extends across Dulwich and the neighbouring areas, and we are happy to confirm your specific postcode over the phone before booking anything.
How long does the work take in a typical Dulwich home?
Most Dulwich 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.
Do you offer free surveys in Dulwich?
Yes. Every enquiry from Dulwich 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.
