SuperQuilt multifoil insulation

Loft insulation in Biggin Hill
We insulate lofts across Biggin Hill — 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 Biggin Hill 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
The reason we lead with the roof rather than the walls or the windows is arithmetic: in a typical Biggin Hill property it is the largest single heat loss and the smallest single bill to fix it.
Biggin Hill's homes
Biggin Hill: what a survey usually turns up
Housing across Biggin Hill 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 Biggin Hill survey is checking for.

Five ways we keep Biggin Hill 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 Biggin Hill houses still have to a full 270mm is the cheapest meaningful energy improvement available to a UK homeowner.
Loft boarding
Storage-readyStorage that does not flatten your insulation. We raise the deck on battens so the full depth survives underneath — the version most Biggin Hill lofts should have had first time.
Loft ladders
Fitted in a dayMany older Biggin Hill 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-oneThe whole loft dealt with at once, for one fixed price. Most Biggin Hill properties are finished within a day.

Questions & answers
Biggin Hill loft insulation — common questions
Will this improve my EPC rating?
It is one of the most reliable ways to improve a rating, because depth is a direct input rather than an inferred assumption. How far it moves depends on everything else about the Biggin Hill property, but the direction is not in doubt.
How long does the work take in a typical Biggin Hill home?
Half a day for insulation alone; a full day for a combined job with boarding, lighting and a ladder. Very large Biggin Hill lofts or heavy strip-outs occasionally run into a second morning, and we tell you that in advance.
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.
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.
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 Biggin Hill property has a room in the roof and depth is constrained, we use 40mm multifoil at rafter level instead.
Do you work in the streets around Biggin Hill?
Yes. Biggin Hill is well within our regular working area, along with everywhere immediately around it — see the full list of areas.
