Air conditioning in Heronsgate: the local picture
VOA council tax data date about 46% of homes across Heronsgate and its surrounding area to the post-war years, 1945 to 1972, and about 75% of households live in detached or semi-detached houses, according to Census 2021 figures. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
Around St John, a quick check of the listing and conservation maps is part of planning any install. About 2.4 miles north stands Chenies Manor House. Listed homes in any area need consent first, so tell us if yours is one.

The process
If the system has to be off for part of the visit, we tell you before any work starts so it doesn’t catch you out. For businesses, we can normally work room by room or zone by zone. On site, it takes a day or more, depending on the number of rooms, the pipe routes and the access. Photos of the room and the outside of the property help us plan a visit to Heronsgate.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Let us know where the consumer unit is
- Move furniture away from the wall where we’ll be working
- Mention any parking restrictions near the property
Getting a price
Some jobs can be priced from photos, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.

Heronsgate questions
Can you do air conditioning in Heronsgate?
Yes. We work across London and the South East from our base in East Grinstead, and Heronsgate is part of that. Get in touch with the details and we reply the same working day.
Will air conditioning in Heronsgate need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. The centre of Heronsgate is in the Heronsgate 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 Three Rivers council, which is usually the planning authority for Heronsgate when it matters.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Where will you put the outdoor unit?
Wall brackets, ground level and flat roofs are all options, chosen for the pipe route, airflow and access. Noise near bedrooms and boundaries is part of the decision and position can affect planning.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Tell us who should receive the paperwork.
Which type of air conditioning is best?
The right one depends on how many rooms you want to cool, how much space there is outside and how visible you want the indoor units to be. Ducted units need a void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
Do I need a new electrical circuit?
Most of the time. We check your consumer unit on the survey and include any electrical work on the quote, and our NICEIC approval covers the installation and certificate.
Landlords, agents and facilities managers
If you look after several properties, we can quote and plan the work across all of them. Every address has its own paperwork, so each one has its own history.
Records are where property maintenance often slips. Every visit is written up, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Honest limits
Some problems need a different service or another trade:
- A ventilation problem rather than a temperature problem
- Gas boiler or central heating faults (we do not work on gas boilers)
- Draughts and missing insulation
Not sure which it is? You can phone 07833 053749 and we will tell you honestly before you book.
Parts of the system we cover

Pricing air conditioning in Heronsgate
You will get a fixed price before we start. It’s based on:
- A single visit or a regular plan
- How easy the units are to reach
- The condition of any existing system
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.
Helping us quote
Before you ask for a quote, gather:
- A close-up of the unit’s label showing the model number
- Your consumer unit or fuse board
- Where the property is and what kind of building it is
Published ranges are a starting point; the quote is built on your property, because every property is different. After a look at the job, by pictures or a survey, the price is fixed. To start, call 07833 053749 or email us.
