Air conditioning installation in Upminster
Air conditioning across Upminster and nearby, from a site survey or diagnosis to sign-off and a fixed price agreed before work begins.
- Uncertainty over the right type and size of system
- Rooms under the roof that stay hot into the night
- Working from home in a room that gets too warm
What we do, step by step
The first job on site is protection: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes anything from a day for one room to several days for a multi-room or ducted system, and we clear up before we go. A note on parking and access helps us plan a visit to Upminster.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Keep pets out of the rooms we’re working in
- Tell us about any building rules, permits or sign-in
- Arrange for someone to be there to let us in

Air conditioning for homes and businesses in Upminster
We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, plus VRF systems for bigger commercial buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be, and we explain the options on the survey. Need an air conditioning installer for Upminster? We are based in East Grinstead and cover London and the South East, as an F-Gas certified company with NICEIC approval.
A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes, and we leave the room clean and the controls explained.
In Upminster, as across London, the rooms that get hottest are usually under the roof or behind large sunny windows. A single wall-mounted unit in the worst room is often where people start, and a multi-split can cover more rooms from one outdoor unit where space outside is short.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Air conditioning in Upminster: local notes
The Valuation Office Agency’s council tax figures show about 52% of homes in the Upminster area date from 1919 to 1939, and the 2021 Census found about 79% of households in detached or semi-detached houses. Homes of that age usually have cavity or solid brick walls, and we check which before planning the pipe route. 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. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Hare Hall, about 2.6 miles north-west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it. If you commute from Upminster station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed.
Upminster is about 2 miles east of Hornchurch, in Greater London. Upminster gets the same approach as every job we take on: a look at the job first, a fixed-price quote and written records at the end. Upminster is one of 764 towns, villages and districts in Greater London we cover for homes and businesses. There’s also a page for Bromley, about 15 miles away.
Not far from Upminster, a recent job of ours was on Greenwich High Road, Greenwich (SE10), about 12 miles south-west: installing a Mitsubishi Electric wall-mounted unit in the retail area and a second unit in the stockroom and office. See the job
Jobs in RM14 and RM11 are looked at, quoted and booked the same way as anywhere else. Our engineers work on Station Road, Latham Place and Deyncourt Gardens and the roads around them.

Why it’s worth doing now in Upminster
Planning ahead beats a rushed decision in a heatwave. A rushed choice is often the wrong size or in the wrong place, which is costly to undo. Booking the survey early gives you time to weigh up the options. Allow time for any approvals your building in Upminster needs.
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.

Your questions about air conditioning in Upminster
Can you do air conditioning in Upminster?
Yes, Upminster is within the area we cover. Tell us a little about the job and we will take it from there.
Can I fit air conditioning in Upminster without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 10 buildings and structures within half a mile of the centre of Upminster. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for Upminster, usually Havering council).
How quickly will you reply?
You will hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Which type of air conditioning is best?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling, which we check on the survey.
Can I have air conditioning in a flat?
It depends on the building and the lease. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
How long will the installation take?
Most single-room systems take a day. Multi-room and ducted systems take longer, depending on the pipe routes and access, and we tell you how long on the quote.
Do I get paperwork after the visit?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
System by system
Wall-mounted split systems
Single-room split systems are typically £1,200–£2,200 + VAT, with supply, fitting, commissioning and the F-Gas paperwork included. Long pipe runs, difficult access and a new circuit affect where your job sits in the range.
Offices, shops and commercial rooms
For bigger buildings, VRF systems link many indoor units to shared outdoor plant. Commercial and VRF systems are priced after a survey and the quote sets out the design.

A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
