Points to plan for in Thamesmead
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
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.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Working hours
Most Thamesmead businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
