The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
London · England
London's roofs are as varied as its neighbourhoods. Long Victorian and Edwardian terraces dominate inner boroughs, interwar semis fill the outer suburbs, and mansion blocks, conversions and new-build apartments add their own considerations. Because so many London lofts have been altered — boarded, part-converted, re-roofed or insulated years ago — a careful look at what is actually up there matters more than any general rule.
We help homeowners across Greater London arrange loft assessments, quotations and installation. Depending on the service and borough, work may be completed by The Insulation Company or an approved installation partner.
Inner-London terraces often have compact lofts with difficult access and original or ageing insulation, and many have been part-boarded for storage in a way that compresses the wool. Outer-London semis in boroughs like Barnet, Enfield, Ealing and Bromley frequently have thin original insulation ripe for a top-up. Flats and conversions raise questions about who is responsible for the roof space, which we help you think through before any work.
London's older terraces were not built with modern ventilation detailing, so blocking the eaves with insulation can cause condensation. We keep the eaves clear and consider ventilation alongside insulation. In converted or part-converted lofts, we check whether the space is a floor to be insulated at joist level or a room-in-roof needing a different, rafter-level approach.
Condensation is a common complaint in poorly ventilated London lofts, particularly in flats and older terraces. We identify the cause before recommending work rather than assuming insulation alone will resolve it.
Across London, access, parking and the state of any existing insulation drive cost more than location alone. Removal of old or contaminated material and any boarding or ventilation work also affect the quotation.
You tell us about your property and what you have noticed in the loft. Nothing is committed at this stage.
We review the property age, roof type, loft access and any existing insulation, moisture or ventilation concerns.
Where required, a survey or assessment is arranged so measurements and conditions can be checked in person.
You receive a clear written recommendation and quotation setting out the scope, materials, price and any guarantee.
Work is completed by The Insulation Company or an approved installation partner, with access protected throughout.
Final checks are carried out, the loft is left clean, and relevant documentation and any guarantee are supplied.
Peter's upstairs ran consistently colder than the ground floor even after a heating service. The 46m² loft was almost completely uninsulated, so we installed a full 300mm Knauf glass mineral wool layer from hatch to gable.

Julie's upstairs rooms felt noticeably colder than the ground floor and lost their heat quickly once the heating went off. By insulating both the loft floor and the roof pitch — and adding a boarded storage area — we gave the whole loft a consistent, well-sealed insulation layer, so the bedrooms hold their warmth for longer and feel more comfortable on cold evenings.

We help homeowners across Greater London — north, south, east, west and central — as well as outer boroughs such as Croydon, Bromley, Enfield, Barnet and Ealing. Request an assessment and we'll confirm coverage for your postcode.
A converted or part-converted loft needs insulation at rafter level rather than across the floor, which is a different job from a standard loft-floor installation. We assess which applies to your space before recommending an approach.
It depends on who is responsible for the roof space and how the building is arranged. We help you understand the options and what would need agreeing before any work.
Customer feedback
Feedback from customers who have used our insulation services.
Very good, prompt and friendly service with an excellent result. Very pleased with the outcome. Well done lads.
Recommended. Friendly, efficient and did a great job in two very dirty loft spaces. All the waste shifted quickly. Top job. Thanks.
These guys are the best! Rory and Leo were very kind to me and got it all done in just a day. Thank you.
Jake and Rory supplied and fitted the insulation in our loft. They did an excellent job and I would recommend them.
It was refreshing to have two young lads who came in and worked incredibly hard on my loft. They came early and left late to get the job done. The best workers I’ve had in a long time, and I would recommend them 100%.
Good lads. They were professional throughout, took extra care and left the place spotless. We can already feel the difference with the fresh insulation.
