Before you book in West Sussex
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Conservation areas
Historic streets and listed buildings in and around West Sussex are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Typical premises in West Sussex
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
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).
