The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
London · England
Bexley occupies the south-eastern edge of Greater London, where suburban development spread out from Bexleyheath, Sidcup and Welling between and after the wars. The borough is dominated by interwar semi-detached housing — long avenues of 1930s semis with generous, shallow-pitched roofs — alongside pockets of older Victorian property around Old Bexley and Crayford, and substantial post-war estates. Bungalows appear on several suburban roads, and newer developments have filled former industrial land near the Thames. Loft work here leans heavily towards topping up thin, settled insulation in wide semi-detached voids.
We help homeowners across Bexley and the surrounding south-east-London area arrange loft assessments, quotations and installation. Depending on the service, work may be completed by The Insulation Company or an approved installation partner.
Bexley's interwar semis, spread across Bexleyheath, Barnehurst and Welling, typically carry thin original insulation that has settled well below current recommendations — a straightforward candidate for a top-up over sound material — and many have boards laid directly on the joists for storage. The pockets of Victorian and Edwardian housing around Old Bexley and Crayford have more compact lofts with steeper access. Suburban bungalows have large roof areas relative to their footprint, where insulation makes a real difference but the low, wide void can be awkward to move around in.
The shallow-pitched roofs of Bexley's interwar semis leave limited room at the eaves, so we take care not to block airflow when building up the insulation. Part-converted lofts — a storage room or study added over the years — are common, so we determine whether the work is at loft-floor joist level or a room-in-roof requiring a rafter-level approach. Boarded-over hatches and storage decking frequently hide compressed, underperforming wool.
Condensation appears in poorly ventilated Bexley lofts, particularly where an extractor has been run into the roof space instead of ducted outside. We establish the cause before assuming insulation alone will cure it.
Across Bexley, the roof area of larger semis and bungalows, the depth and state of existing insulation, access and parking, and any removal, boarding or ventilation work influence the quotation more than the specific street.
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.
These are examples of our work elsewhere, shown to illustrate what a project involves. They did not necessarily take place in Bexley.
Emma's front and rear bedrooms, split by a central chimney breast, both cooled quickly. We insulated the 40m² floor on both sides of the chimney to a full 300mm depth.
Example from our project library
Tom noticed condensation on the bedroom windows and rapid overnight heat loss. We gave his compact 31m² loft a full 300mm Knauf glass mineral wool layer, fitted carefully around the hatch and low edge bays.
Example from our project library
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.

Yes. Bungalows have a large roof area relative to their footprint, so loft insulation makes a real difference, though the low, wide void can be awkward to work in. We assess access and airflow and recommend a suitable build-up.
Often not. Interwar semis were usually insulated to depths well below today's standards, and the original material tends to settle over time, so a top-up over sound wool is frequently worthwhile. We check what is actually up there first.
Customer feedback
Feedback from customers who have used our insulation services.
The boys were very kind and well advised. They got the job done quickly and smoothly. My loft was in pretty bad shape, as I have a slight hoarding problem, and they passed no judgement. Thank you for your service.
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%.
