What to think about in Llanelli
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Conservation areas
Historic streets and listed buildings in and around Llanelli are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Typical premises in Llanelli
