What to think about in Worthing
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
Leased premises
If your Worthing 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.
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 Worthing 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.
Who we work with in Worthing
- 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.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
