The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
South West Wales · Wales
Llanelli built its name on tinplate, and rows of workers' terraces from that era still fill the town centre and the surrounding districts of Felinfoel, Bynea and Llwynhendy. Interwar and post-war semis and estates spread through Morfa and the later suburbs, while newer housing has grown toward the Millennium Coastal Park and the town's edge. Sitting on the Loughor estuary, Llanelli is very much a coastal town, so exposure and moisture shape the conversation as much as the age of the house.
We help homeowners across Llanelli and the surrounding Carmarthenshire 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 tinplate-era terraces of Llanelli often have compact, steeply pitched lofts, solid walls and insulation laid many years ago that has settled and thinned. Interwar and post-war semis across Morfa and the outer streets usually carry thin original wool that suits a top-up, and many already have storage boards laid straight onto the joists. Coastal and village cottages toward the estuary and the Gwendraeth valley can have irregular roofs worth a close look. Newer homes near the coastal park generally already have insulation, so the useful question becomes boarding, ventilation or added depth.
Llanelli's estuary and coastal position brings salt-laden air, wind-driven rain and higher humidity, so ventilation deserves careful thought. Packing insulation into the eaves of an exposed terrace can block airflow and trap moisture, so we keep the eaves clear and treat ventilation and insulation together. On the most weather-beaten roofs we also check how the covering is coping before recommending a build-up.
Estuary humidity and wind-driven rain make condensation and damp common in poorly ventilated Llanelli lofts. Insulation alone will not cure a moisture problem, so we identify the actual cause — airflow, driving rain, a leak or an extractor venting into the loft — before recommending work.
In Llanelli, cost is driven mainly by loft access on the terraced streets, roof exposure, whether old insulation needs removing, and any boarding or ventilation work. Access to outlying coastal and village homes can also be a factor.
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 Llanelli.
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.

It can. Coastal and estuary roofs deal with salt air, wind-driven rain and higher humidity, so we keep the eaves ventilated and manage moisture alongside insulation rather than simply adding depth.
Coastal humidity makes it more likely in poorly ventilated roofs. If you have seen condensation or staining, we look at the cause — airflow, driving rain, a leak or an extractor venting into the loft — because insulation alone will not resolve it.
Customer feedback
Feedback from customers who have used our insulation services.
The crew showed up on time, explained everything clearly, finished faster than expected, and we noticed the house felt more comfortable almost immediately.
I was looking at getting my roof insulated but was shocked by the price of some of the quotes I received. I stumbled across these guys and could not be more pleased. Great quality work for a fantastic price.
Smooth and stress-free process. The team were polite, efficient and did a great job. Really pleased with the results. Thanks guys!
These guys were the nicest and provided the best service. They did the job much quicker than expected. Very happy with the job and the price. Highly recommend.
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.
