Before you book in Eltham
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
Working hours
Most Eltham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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 Eltham
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
