SuperQuilt multifoil insulation
A/A+ fire ratedWhere a Bloomsbury 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 Bloomsbury
Bloomsbury sits in Central London, where the housing is dominated by Georgian and early Victorian terraces, mansion blocks and converted commercial buildings, much of it listed or in a conservation area. Much of it was insulated to a standard that has since been superseded twice over. We put that right — properly, in a day, for a price agreed in advance.

Why it matters
The case for insulating your Bloomsbury 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 Bloomsbury property it is the largest single heat loss and the smallest single bill to fix it.
Bloomsbury's homes
Bloomsbury: what a survey usually turns up
Housing across Bloomsbury and the surrounding Central London area is largely Georgian and early Victorian terraces, mansion blocks and converted commercial buildings, much of it listed or in a conservation area, built through the late eighteenth and nineteenth centuries. 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 — roof spaces here are frequently tiny, awkwardly shaped and shared across a terrace, which makes access rather than area the limiting factor — and you have most of what a Bloomsbury survey is checking for.
Our services in Bloomsbury
Five ways we keep Bloomsbury 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 Bloomsbury houses still have to a full 270mm is the cheapest meaningful energy improvement available to a UK homeowner.
Loft boarding
Storage-readyBoards laid straight onto joists crush 270mm into 100mm. We batten out instead, so Bloomsbury homeowners get usable storage and keep the insulation they paid for.
Loft ladders
Fitted in a dayMany older Bloomsbury 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-oneOne team, one survey, one sequence of work. The insulation depth sets the batten height, the batten height sets the ladder landing — which is why doing it piecemeal costs more.

Questions & answers
Bloomsbury loft insulation — common questions
Do I need planning permission in Bloomsbury?
None of the work we do requires planning permission. If your Bloomsbury 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.
Do you remove the old insulation?
It depends what is up there. Cross-laying a new layer over sound existing material is both cheaper and perfectly correct. Failed, contaminated or loose-fill material is stripped, bagged and disposed of — slow work, and we show it as its own line on the quote.
How much does loft insulation cost in Bloomsbury?
We price Bloomsbury jobs after a free survey, itemised so you can see what the insulation, any boarding and any removal each cost. There is no call-out charge and the figure does not move once it is written. The London cost guide explains what drives it.
Do you offer free surveys in Bloomsbury?
Free, with no call-out fee and no pressure. A meaningful proportion of our Bloomsbury surveys conclude that the loft is already adequately insulated and the homeowner should keep their money — which is a perfectly normal outcome.
What happens to the water tank and pipes?
They end up above the new insulation line, in a colder space than before, so they must be lagged. The cold water tank is insulated on its sides and lid but never underneath — the warmth rising from the house is what keeps it from freezing. We handle this as part of the job.
Can I still use my Bloomsbury 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.
