Air conditioning in Southernden: local notes

VOA council tax data show about 32% of homes in and around Southernden were built in 2000 or later, and the 2021 Census found about 74% of households in detached or semi-detached houses. Newer homes typically have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.

About 4.8 miles north stands Leeds Castle. Listed homes in any area need consent first, so tell us if yours is one. Starting with one room is common, and the outdoor unit can be chosen with more rooms in mind.

What the work involves, system by system

Offices, shops and commercial rooms

For bigger buildings, VRF systems link many indoor units to shared outdoor plant. VRF and larger commercial jobs are priced after a survey, with the design explained in the quote.

Multi-split systems

With a multi-split, one outdoor unit serves two or more rooms. It saves wall space outside and suits homes where several rooms need cooling and each indoor unit has its own controls.

Your questions about air conditioning in Southernden

Do I need planning permission for air conditioning in Southernden?

There’s no single answer: the building and the outdoor unit position decide it. Around 4 listed entries sit within 0.5 miles of central Southernden. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask Maidstone council, which is usually the planning authority for Southernden.

Is Southernden within the area you cover?

Yes. Southernden is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.

Will you make a mess?

We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards before we leave.

How do you size the system?

It depends on the room, not only its floor area. 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.

Can I use air conditioning to heat a room?

Most of the time, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.

Which brands do you work with?

We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.

How much does air conditioning installation cost?

From £1,200 + VAT for a single-room split, with a typical range of £1,200–£2,200 + VAT. That covers supply, installation, commissioning and the F-Gas paperwork, and we fix it after a survey or from your pictures.

What you can do yourself, and what needs us

Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and ring 07833 053749, or email if that’s easier.

There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.

Looking after your system

Aftercare is straightforward, and it helps at the next service:

  • Don’t cover or box in the outdoor unit
  • Report drips, noises or error codes right away
  • Keep the room closed while it runs

Commissioning is the last stage: every mode is tested before we go. We check it’s running as the manufacturer intends, then show you the controls and the timer, so you’re confident using it.

Use sensible settings. Choose the right mode and a comfortable temperature rather than the lowest setting and keep doors and windows shut while it runs.

The process

Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it takes about a day for a single-room system, longer for multi-room and ducted systems. If a lane or gateway near Southernden is tight for a van, let us know and we will plan for it.

  1. First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
  2. Then the prescription: the right system and size for each room, on a fixed-price quote.
  3. Then the work: units up, pipes and drain run, and a new circuit where necessary.
  4. Checks: a pressure test for leaks, then a vacuum to clear moisture.
  5. The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.

How to prepare

  • Make sure we can reach the outdoor unit, or where it will go
  • Let us know if the units are on a roof, a high wall or in a locked area
  • Find the manual or the paperwork for the system, if you have it
