Local points to consider
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.
Access and parking
Town-centre jobs in Chalfont St Peter 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.
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.
Working hours
Most Chalfont St Peter businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Which postcodes do you cover in Chalfont St Peter?
All of them, including HP8, HP9, SL9 and WD3. 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.
