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

Loft insulation in Harold Hill
If your Harold Hill 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.

Why it matters
The case for insulating your Harold 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 Harold Hill property it is the largest single heat loss and the smallest single bill to fix it.
Harold Hill's homes
Harold Hill housing and the insulation problem
Like much of East London, Harold Hill is built largely of Victorian terraces, interwar council-built estates, post-war rebuilding and a great deal of recent conversion and new build. Housing of that age has a particular relationship with heat: solid or early cavity walls, single-glazed openings replaced piecemeal over the years, and a roof void that was simply a void until somebody decided to put something in it.
The roof is where the largest single share of that heat goes, and it is also the cheapest part of the building to improve. There is no structural work, no planning permission, no scaffolding and no disruption beyond a day with the hatch open. For most Harold Hill homeowners it is the first upgrade that makes clear financial sense and the last one they get round to.
The complication locally is that wartime damage and post-war rebuilding mean two adjoining houses on the same street can have entirely different roof construction.
Our services in Harold Hill
Five ways we keep Harold 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 depthThe standard job, done to standard: two layers, the second laid across the joists to kill the cold bridge, eaves left clear. Most Harold Hill lofts are finished in half a day.
Loft boarding
Storage-readyBoards laid straight onto joists crush 270mm into 100mm. We batten out instead, so Harold Hill homeowners get usable storage and keep the insulation they paid for.
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
Harold Hill loft insulation — common questions
Do you work in the streets around Harold Hill?
We do. Coverage extends across Harold Hill and the neighbouring areas, and we are happy to confirm your specific postcode over the phone before booking anything.
How much does loft insulation cost in Harold Hill?
There is no single figure, and anyone offering one for Harold Hill without seeing the loft is guessing. The largest swing factor is almost always whether the existing material can be topped over or has to be stripped out and disposed of. We survey free of charge and quote a fixed price afterwards.
Can I still use my Harold Hill 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.
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.
