Air conditioning in Shenfield, done properly
We approach an installation much as a doctor approaches a patient: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. For air conditioning in Shenfield, you get one team and one number from survey to sign-off, wherever you are in Essex.
Many installs in Shenfield can go ahead as permitted development, but listed buildings, conservation areas and flats often need consent first: we flag that at the survey.
Around Shenfield, older cottages and newer houses can be very different to work on. Thick walls and beams mean planning the pipe route carefully, and if the home is listed, consent comes before any work.
Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

How the job changes from property to property
Ducted systems
One ducted unit can serve more than one room through separate ducts and grilles, which suits new builds, extensions and refurbishments where ceilings are open.
Offices, shops and commercial rooms
Bigger systems in buildings come with extra duties, such as a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange the inspection and get the system ready for it.
Air conditioning in Shenfield: the local picture
About 54% of homes in the Shenfield area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 84% of households live in detached or semi-detached houses, according to the last census (2021). We check the wall construction on homes of that age, as it decides how the pipework goes through. Houses usually have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Around Church of St Mary the Virgin, a quick check of the listing and conservation maps is part of planning any install. Ingatestone Hall, about 3.8 miles north-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
Shenfield is about 1 mile north-east of Brentwood, in Essex. Wherever you are in the CM15 postcode area, our engineers can take on air conditioning. In Essex alone we list 644 places, and Shenfield is one. For properties nearby, see our London page, about 20 miles away.

Shenfield questions
Is Shenfield within the area you cover?
Yes. Shenfield is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is air conditioning in Shenfield permitted development?
There’s no single answer: the building and the outdoor unit position decide it. Around 13 listed entries sit within 0.5 miles of central Shenfield. 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 isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for Shenfield, typically Brentwood council).
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do you provide F-Gas records?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book and we’ll gladly show you ours.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Which type of system should I choose?
There’s no single best type. Wall-mounted splits suit single rooms, multi-splits run several rooms from one outdoor unit, ducted systems hide the unit in the ceiling, and cassettes suit offices and larger rooms. We recommend one on the survey and explain why.
For landlords and property managers
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side, and the paperwork can go to both.
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
What affects the cost of air conditioning
The price is fixed before any work begins. It takes into account:
- The equipment or parts the job needs
- How easy the units are to reach
- What state the existing equipment is in
What you pay reflects the actual work. That’s why we look at the job first, from photos or on a survey, and why the quote is fixed before we start.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- Your consumer unit or fuse board
- Your installation or service records
- A few pictures of the room and the wall the unit is on, or will go on
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

The process
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes about a day for a single-room system, longer for multi-room and ducted systems. We plan the visit to Shenfield from the survey or your photos.
- 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.
- 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.
Before we arrive
- Keep pets and children away from the work area
- Let us know where the consumer unit is
- Name a contact who can meet us at the agreed time
