Loft insulation in Friern Barnet
Roughly a quarter of an uninsulated home's heat escapes through the roof. For Friern Barnet homeowners that is the cheapest problem in the house to fix, and the one most likely to have been fixed badly the first time. We do it properly.

Why it matters
The case for insulating your Friern 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
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 Friern Barnet property it is the largest single heat loss and the smallest single bill to fix it.
Friern Barnet's homes
Friern Barnet: what a survey usually turns up
Housing across Friern Barnet and the surrounding North London area is largely Victorian and Edwardian terraces, generous interwar semis and a scattering of post-war infill, built through the 1870s 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 — 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 — and you have most of what a Friern Barnet survey is checking for.

Five ways we keep Friern 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 Friern Barnet 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 Friern Barnet lofts should have had first time.
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 Friern Barnet home actually has.
Loft makeovers
All-in-oneThe whole loft dealt with at once, for one fixed price. Most Friern Barnet properties are finished within a day.

Questions & answers
Friern Barnet loft insulation — common questions
What insulation depth do you fit?
Full recommended depth of 270mm as standard. Going deeper gives sharply diminishing returns; stopping short leaves money on the table every winter. For sloping ceilings in Friern Barnet loft rooms, multifoil at around 40mm is the practical alternative.
Can you fit a loft ladder at the same time?
We fit ladders alongside insulation and boarding routinely — it is one of the main reasons the combined makeover works out cheaper than booking the elements separately.
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.
How long does the work take in a typical Friern Barnet home?
Most Friern Barnet 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.
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 Friern Barnet property, but the direction is not in doubt.
Can I still use my Friern Barnet 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.
