Points to plan for in Eastleigh
Refrigerant rules
Since 1 January 2025, new single split systems holding under 3 kg of refrigerant in Great Britain cannot use refrigerant with a GWP of 750 or more — in practice, R32 or lower.
Conservation areas
Historic streets and listed buildings in and around Eastleigh are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
One outdoor unit, many rooms
Multi-splits save wall space but share a single compressor. For server rooms or critical spaces we recommend dedicated systems.
Leased premises
If your Eastleigh 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 Eastleigh
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
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.
