SuperQuilt multifoil insulation
A/A+ fire ratedMultifoil earns its place in Swanley roofs where depth is the binding constraint — period timbers, low headroom, or a conversion already boarded out.

Loft insulation in Swanley
If your Swanley 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.

None of this requires permissions, scaffolding or structural work. In Swanley, as anywhere, it is a day's work with materials that cost little relative to what they save.
Swanley's homes
What we find in Swanley roof spaces
The roofs over Swanley are mostly clay tile and slate pitched roofs on the older stock, concrete tile on newer development, and they were built during the 1880s onwards for a housing market with no expectation of thermal performance. Insulation arrived later, retrofitted into spaces never designed to accommodate it, and the results vary enormously from street to street.
On survey we routinely find the same handful of problems: material compressed to a fraction of its depth by boards laid straight onto the joists, insulation packed hard into the eaves and sealing off the roof's only ventilation path, hatches left as bare uninsulated panels, and recessed downlighters buried under wool. None of these are exotic and all of them are fixable — but they need finding first.
Properties closer to the estuary see more exposure to wind-driven rain, which makes checking for existing moisture in the roof space especially worthwhile, which is one more reason we measure rather than assume.

Five ways we keep Swanley 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 depthThe standard job, done to standard: two layers, the second laid across the joists to kill the cold bridge, eaves left clear. Most Swanley lofts are finished in half a day.
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 dayFixed, stable access instead of a stepladder on the landing. Timber, aluminium or concertina, chosen to suit the space your Swanley home actually has.
Loft makeovers
All-in-oneInsulation, boarding, lighting and a ladder handled together in one visit — cheaper and better sequenced than buying the four separately.
Not sure what your Swanley loft needs?
Describe the property and what is bothering you about it, and we will recommend the right combination — or tell you that nothing needs doing.

Questions & answers
Swanley loft insulation — common questions
Do I need planning permission in Swanley?
None of the work we do requires planning permission. If your Swanley property is listed or in a conservation area, that affects the roof covering and external alterations rather than insulation laid inside the roof space, though it is always worth mentioning at survey.
Can I still use my Swanley loft for storage afterwards?
Absolutely. The only wrong way to do it is to board flat onto the joists. We raise the deck on battens or loft legs, board it in tongue-and-groove panels and leave the eaves clear so the roof keeps ventilating.
What insulation depth do you fit?
270mm of mineral wool, cross-laid — the depth current building regulations guidance points to for a cold loft. Where a Swanley property has a room in the roof and depth is constrained, we use 40mm multifoil at rafter level instead.
Do you offer free surveys in Swanley?
Free, with no call-out fee and no pressure. A meaningful proportion of our Swanley surveys conclude that the loft is already adequately insulated and the homeowner should keep their money — which is a perfectly normal outcome.
Will insulating my loft cause damp?
It can if the ventilation is ignored, which is why we check it before anything comes off the van. If we find an existing condensation problem in a Swanley loft, we deal with the cause first rather than insulating over it.
Do you remove the old insulation?
Where it can stay, it stays and we top over it. Where it cannot, it goes and the disposal is included in the fixed price. You will never find out about removal costs mid-job — that is decided at survey.
