Before you book in Brentwood
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
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.
Coordination
Ceiling, lighting, sprinkler and electrical layouts are coordinated early.
Leased premises
If your Brentwood premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Typical premises in Brentwood

Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
