SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Barnet 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.

Loft insulation in Barnet
Insulation is the one home improvement that starts paying you back on the next heating cycle rather than in a decade. We fit it across Barnet — to full depth, with the eaves kept clear and the hatch sealed, which is where most jobs quietly go wrong.

Why it matters
The case for insulating your Barnet 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

90%less radiant heat loss with SuperQuilt multifoil
Those figures are national, but the logic is entirely local: the roof over a Barnet house is the cheapest part of it to improve, and the part losing the most.
Barnet's homes
What we find in Barnet roof spaces
The roofs over Barnet are mostly steeply pitched slate and clay tile roofs with usable, walkable voids above the top floor, and they were built during the 1870s through the 1930s 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.
Many of the larger houses were divided into flats decades ago, so the loft often sits above a top-floor conversion with its own separate access, which is one more reason we measure rather than assume.

Five ways we keep Barnet 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 Barnet houses still have to a full 270mm is the cheapest meaningful energy improvement available to a UK homeowner.
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
Barnet loft insulation — common questions
Do you offer free surveys in Barnet?
Always, and there is no charge or obligation attached. A survey takes around half an hour. We would rather spend it establishing what your Barnet loft actually needs than quote blind and revise the price later.
How long does the work take in a typical Barnet home?
Half a day for insulation alone; a full day for a combined job with boarding, lighting and a ladder. Very large Barnet lofts or heavy strip-outs occasionally run into a second morning, and we tell you that in advance.
Do you work in the streets around Barnet?
Yes. Barnet is well within our regular working area, along with everywhere immediately around it — see the full list of areas.
