From enquiry to handover in Caterham
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route. For sites in Caterham we confirm access and parking beforehand.
Mount the units
Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.
Pipe and wire
Pipework, interconnecting cable and condensate are run and made off neatly.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Points to plan for in Caterham
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Access and parking
Town-centre jobs in Caterham often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
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.
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.
Who we work with in Caterham
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- 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.

Do you also cover Coulsdon, Purley and Redhill?
Yes. Alongside Caterham, we also cover Coulsdon, Purley and Redhill. Each has its own page with local guide prices.
Which postcodes do you cover in Caterham?
All of them, including CR3. Give us your postcode when you enquire and we will confirm the visit details.
Does a small split need F-gas leak checks?
It depends on the refrigerant charge and type. Many small R32 splits fall below the 5 tonnes CO2 equivalent threshold for mandatory leak checks, but they still need installing and servicing by F-gas certified engineers.
Single split or multi-split?
Separate singles are more resilient and can be cheaper for two rooms; a multi-split saves outdoor space. We price both where it is close.
