How a job in Northolt works
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route. For sites in Northolt we confirm access and parking beforehand.
Mount the units
Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.
Pipe and wire
Pipework, interconnecting cable and condensate are run and made off neatly.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Local points to consider
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.
Conservation areas
Historic streets and listed buildings in and around Northolt are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
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.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Yes. Alongside Northolt, we also cover Greenford, Harrow and Southall. Each has its own page with local guide prices.
Which postcodes do you cover in Northolt?
All of them, including UB5. 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.
