How we work in East Sussex

  1. Survey

    We size the unit to the room and agree indoor and outdoor positions and the pipe route.

  2. Mount the units

    Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.

  3. Pipe and wire

    Pipework, interconnecting cable and condensate are run and made off neatly. We keep work areas in East Sussex screened and tidy at the end of each day.

  4. Test and commission

    Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.

Things to check in East Sussex

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.

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.

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.

Shared buildings

In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.

Who we work with in East Sussex

  • Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
  • Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
  • Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
  • Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.

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.

FAQs for East Sussex

How much does a split air conditioning system cost in East Sussex?

Guide prices in East Sussex run from about £1,650 to £3,395 per system, plus VAT. A typical job (two-room multi-split) costs £3,950–£6,850 plus VAT. We fix the price in writing after a free survey.

Do you also cover West Sussex, Surrey and Kent?

Yes. Alongside East Sussex, we also cover West Sussex, Surrey and Kent. Each has its own page with local guide prices.

Can a split system heat in winter?

Yes. Modern split systems are heat pumps and can heat efficiently down to well below freezing.

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.
