South Harefield: your questions answered
Do you cover South Harefield for air conditioning?
We do: South Harefield falls inside our working area. Tell us a little about the job and we will take it from there.
Can I fit air conditioning in South Harefield without planning permission?
The answer turns on the property and where the outdoor unit would sit. Central South Harefield is a short walk from the Widewater Lock Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the planning department at Hillingdon council, typically the authority for South Harefield when it matters.
Can the outdoor unit go on a roof or at ground level?
We agree it with you on the survey. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We explain the options and any permissions to check.
Do I need a new electrical circuit?
Most of the time, yes: a dedicated circuit is needed. Under Part P, a new circuit has to be notified unless a registered competent person does it, and we are NICEIC approved, so we can install and certify it.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
How do you size the system?
Floor area is only part of it. Windows, the direction the room faces, the roof above and the people and equipment in it all count, and we take them all into account on the survey.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
How we handle air conditioning in South Harefield
Any installation we do in South Harefield follows the same process as everywhere else we work: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. You know the price before we start and the paperwork is in your hands when we finish. Whether you call it air con, air conditioning or an air-to-air heat pump, in South Harefield it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
New circuits are done by our NICEIC approved electricians, so there’s no separate electrician or building control visit to arrange.
Around South Harefield, many people choose a system that heats as well as cools, which suits rooms the main heating doesn’t reach well, such as a garden room or loft.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

What affects the quote in South Harefield
The price is fixed before any work begins. It takes into account:
- Whether the existing supply is suitable
- A single visit or a regular plan
- Access, including height, roofs and ladders
What you pay depends on the type of system and how many units are involved, the access and the parts and time the job needs. You get a fixed price before we start, so you know where you stand.
Asking for a quote
You do not need the technical terms. Just send:
- Photos showing the indoor unit and the space around it
- A close-up of the unit’s label showing the model number
- The outdoor side of the property, including any roof or flat area
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price before any work starts.

Do you need air conditioning in South Harefield?
Computers, screens, lighting and people all give off heat. A small office or a busy room can warm up fast with equipment and people in it, even when it is not especially hot outside.
What we are most often called about:
- Working from home in a room that gets too warm
- Too many options and no clear advice
- A system on old refrigerant that is due for replacement
Around Church of St Mary the Virgin, a quick check of the listing and conservation maps is part of planning any install.

- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
