- Uncertainty over the right type and size of system
- Rooms heated by plug-in heaters
- An office, shop or restaurant that’s uncomfortable for staff and customers
How it works
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. We plan the visit to Writtle from the survey or your photos.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Make sure we can reach the outdoor unit, or where it will go
- Make sure someone can let us in at the agreed time
How to get a quote
Here’s what helps us quote: the address and the type of property, pictures of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Once you have those, give us a ring on 07833 053749 or send an email.

Air conditioning for homes and businesses in Writtle
Good air conditioning starts with the right system in the right place. We look at each room’s size, glazing, orientation and use, then agree where the indoor and outdoor units go and how the pipework, cable and condensate drain will run before you get a fixed-price quote. If you want air conditioning in Writtle, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork, wherever you are in Essex.
Most single-room installs in Writtle are done in a day, while multi-split systems for several rooms can take longer, and we leave the room clean and the controls explained.
A cottage and a newer house near Writtle are very different jobs. Thick walls and beams mean planning the pipe route carefully, and if the home is listed, consent comes before any work.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Air conditioning around Writtle
VOA council tax data date about 60% of homes in the Writtle area to the post-war years, 1945 to 1972, and about 73% of households live in detached or semi-detached houses, according to the 2021 Census. We check the wall construction on homes of that age, as it decides how the pipework goes through. Detached and semi-detached houses usually have space for the outdoor unit, and several rooms can share one on a multi-split.
About 1.4 miles south-east stands Hylands. Listed homes in any area need consent first, so tell us if yours is one.

Common questions in Writtle
Is planning permission needed for air conditioning in Writtle?
The answer turns on the property and where the outdoor unit would sit. There’s a conservation area, the Writtle Conservation Area, close to central Writtle. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the planning department at Chelmsford council, typically the authority for Writtle.
Do you cover Writtle for air conditioning?
Yes, Writtle is within the area we cover. Just phone 07833 053749 with a few details.
Will you need to do electrical work?
Most systems need their own supply from the consumer unit. Under Part P, a new circuit has to be notified unless a registered competent person does it, and we’re NICEIC approved, so we can install and certify it.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
What does it cost to install air conditioning?
For one room, a split system is typically £1,200–£2,200 + VAT. A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, with supply, fitting, commissioning and F-Gas documentation included. The price is fixed before any work starts.
What size air conditioning unit do I need?
Sizing is done on the survey, room by room. Too small, and it runs flat out; too big, and it switches on and off and wastes energy and we explain the output we recommend.
How soon will you get back to me?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
After we’ve gone
After the visit, a few habits help:
- Keep to the service interval the manufacturer recommends
- Flag any change in how the system sounds or performs
- Let filters dry fully before you put them back
The filters are the one part you’ll look after yourself, so we show you how. In busy periods, clean them every few weeks, or as the manual recommends, and keep the outdoor unit clear of leaves and clutter.
Don’t ignore small changes. Water from the indoor unit, a new rattle or a code on the display normally means something needs attention and catching it early keeps the repair small.
What we’re called out for in Writtle
Portable units are often where people start, and why they call us. Portables push their warm air out through a hose in the window, so the window can’t close properly and the noisy part of the unit is in the room. With a split system, the compressor lives outside.
What we’re most often called about:
- Uncertainty over the right type and size of system
- A loft room or top floor that bakes in summer
- An ageing air conditioning system near the end of its life
Homes near Church of All Saints are a good example of where we look up the heritage status of the building before fixing anything to it.
