How a job in Sunbury-on-Thames works
Survey
We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go. For sites in Sunbury-on-Thames we confirm access and parking beforehand.
Design and quote
You get a written specification with unit sizes, positions, pipe routes and a fixed price — plus any planning, landlord or noise points to resolve first.
First fix
Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung.
Install and test
Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.
Commission and hand over
We set up controls, check air flows and temperatures, show your team how to use it and hand over the F-gas and commissioning paperwork.
Local points to consider
Power
Larger systems need a dedicated supply from the distribution board. We check capacity at survey so there are no surprises on install day.
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.
Planning and noise
Outdoor units on commercial buildings often need planning permission — particularly on a front elevation, in a conservation area or on a listed building — and councils may ask for a noise assessment.
Conservation areas
Historic streets and listed buildings in and around Sunbury-on-Thames are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
