The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
East of England · England
Cambridge blends a tightly protected historic core with street after street of Victorian terraces in Romsey, Petersfield and around Mill Road, interwar semis in Cherry Hinton and fast-growing modern developments at Trumpington, Eddington and Cambourne on the city's edge. That range means loft work here is rarely standard: a narrow Romsey terrace with a shallow, awkward loft and ageing felt asks for a very different approach from a recent Trumpington house that already carries insulation and a boarded hatch.
We help homeowners across Cambridge and the surrounding Cambridgeshire area arrange loft assessments, quotations and installation. Depending on the service, work may be completed by The Insulation Company or an approved installation partner.
The terraced streets off Mill Road often have compact lofts with limited headroom, access squeezed over a stairwell, and insulation laid years ago that has since settled and thinned. Much of suburban Cambridge is interwar and post-war semi-detached housing in Cherry Hinton, Arbury and Chesterton, typically suited to a top-up over sound existing wool, often with boards laid straight onto the joists for storage. Newer homes at Trumpington and Eddington usually have insulation already, so the useful question is whether adding depth, improving ventilation or boarding out is worthwhile.
East Anglia is one of the drier regions of Britain, but it is also flat, open and exposed, and Cambridge lofts still suffer condensation where airflow is poor. Cramming insulation into the eaves of an older terrace blocks what little ventilation the roof has, so we keep the eaves clear and treat ventilation and insulation together. In conservation areas and near older college property, we assess how the roof breathes before recommending any build-up.
Cold, still winter nights and poorly ventilated roof spaces make condensation a common complaint in Cambridge lofts. Insulation alone will not cure a moisture problem, so we check the actual cause — airflow, a roof leak or an extractor venting into the loft — before recommending work.
In Cambridge, cost is driven mainly by loft access on the terraced streets around Mill Road, whether old insulation needs removing, and any boarding or ventilation work. Restricted parking and permit zones near the centre can also be a factor.
Many Cambridge lofts already have some insulation. Where it is sound we can top it up to a suitable wool build-up; where it is damp, contaminated or compressed we remove and replace it. A short assessment tells you which applies.
These are examples of our work elsewhere, shown to illustrate what a project involves. They did not necessarily take place in Cambridge.
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.

We help homeowners across Cambridge and nearby Cambridgeshire, from Romsey, Petersfield and Mill Road to Cherry Hinton, Chesterton and Trumpington, as well as Ely, Newmarket and Cambourne. Request an assessment and we'll confirm coverage for your postcode.
It can. Insulating the loft itself is usually internal work, but on older and protected property we take extra care with breathability and airflow, keep the eaves clear and assess how the roof copes before recommending a build-up.
Even in drier East Anglia, poor ventilation causes condensation. If you have noticed damp or staining, we look at the cause — airflow, a leak or an extractor venting into the loft — because insulation alone will not fix a moisture problem.
Customer feedback
Feedback from customers who have used our insulation services.
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.
Top man Leonardo with the insulation. Did the insulation in a day.
