Codicote questions
Do I need planning permission for air conditioning in Codicote?
It depends on the property. The Codicote Conservation Area takes in the middle of Codicote. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Codicote, typically North Hertfordshire council).
Will you come out to Codicote?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Can I do any of the installation myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do you have a 24/7 line?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we will advise on what to do next.

A single-room split system is typically £1,200–£2,200 + VAT, while a two-room multi-split is typically £2,800–£4,500 + VAT and three to five rooms £4,500–£8,500 + VAT.

AirCon Doctor works across London and the South East from East Grinstead, with a fixed-price quote before any work starts.
A cottage and a newer house near Codicote are very different jobs. Thick walls and beams mean planning the pipe route carefully, and a listed home needs consent before anything is fixed to it.
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.

The process
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. The work takes anything from a day for one room to several days for a multi-room or ducted system. Let us know how to reach the outside wall or outdoor unit at your property near Codicote.
- First comes a site survey, or photos and measurements for a straightforward job.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Getting ready for the visit
- Find the manual or the paperwork for the system, if you have it
- Make sure someone can let us in at the agreed time
- Let us know if the building has a permit or sign-in process
Getting a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.

Looking after your system
How well a system lasts depends on use and care. Here’s what we suggest:
- Close windows and doors while the system is cooling
- Keep the outdoor unit clear of leaves, plants and clutter
- Refit filters properly after cleaning
Commissioning is the last stage: every mode is tested before we go. Once it’s running properly, we take you through the controls and settings so you know how to get the best from it.
Set it and leave it. Choose the right mode and a comfortable temperature rather than the lowest setting, and close windows and doors while it’s cooling.
Why deal with it now?
Refrigerant rules have changed what new systems use. From 2025, single splits under 3 kg can’t use refrigerants with a GWP over 750, so new splits use refrigerants such as R32, with a GWP of 675. Older R410A systems have a GWP of 2088. A dirty or faulty system works harder and costs more to run.
Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we will go through it with you.

What we are called out for in Codicote
Commercial spaces gain heat from people, equipment, lighting and glazing. Comfortable staff and customers are the usual reason businesses get in touch, and some rooms need cooling for the equipment as much as the people.
Most people get in touch after spotting one of these:
- Portable units that are noisy and barely cope
- Expensive direct electric heating
- A business premises that overheats in summer
Living close to Parish Church of St Giles? Some older properties in parts like that are protected, and the survey finds out whether yours is.

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
