Air conditioning in Plummers Plain, done properly
Most air conditioning needs its own electrical supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. Air con, air conditioning, a split system: whatever you call it, it’s the job we do every week across West Sussex.
New circuits are done by our NICEIC approved electricians, so the electrical paperwork comes with the installation.
Homes around Plummers Plain usually have room outside for an outdoor unit. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

FAQs for Plummers Plain
Can I get a fixed-price quote for air conditioning in Plummers Plain?
The easiest way is to call us on 07833 053749 or fill in the contact form with a few details and photos. We reply the same working day, and the quote is fixed before any work starts.
Is Plummers Plain in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Plummers Plain is part of that. Tell us a little about the job and we’ll take it from there.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
Will you need to do electrical work?
In most cases. We check your consumer unit on the survey and include any electrical work on the quote and we install and certify the circuit as NICEIC approved contractors.
Do you have a 24/7 line?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
Where will you put the outdoor unit?
The position is agreed on the survey, not on the day. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We explain the options and any permissions to check.
How the visit works
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Somewhere like Plummers Plain, it helps to know about lanes, gates and where to park.
- We survey the property, or work from your pictures for a simple job.
- The system is sized, positions are agreed and the price is fixed.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Getting ready for the visit
- Let us know if the building has a permit or sign-in process
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know where we can park and unload
How to get a quote
Here’s what helps us quote: the address and the type of property, a few pictures, the brand and model of anything already fitted and any symptoms, from error codes to drips. Then phone 07833 053749.

Before you call an engineer
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
How the job changes from property to property
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, with the design explained in the quote.
Multi-split systems
A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. The pipe routes to each room make the biggest difference to the price.
