- Deciding on the outdoor unit position
- Planning and permitted development questions
How the visit works
Each visit runs to the same pattern: agree the plan on site, protect the area, do the work, test what we’ve done and talk you through it. On site, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Getting to the outside of the property matters more than parking in a place like Markyate.
- First we talk through the property and the current system.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- You get a fixed price, with any grant and the VAT set out.
- Installation, commissioning and MCS registration complete the job.
Getting ready for the visit
- Mention any managing agent or landlord rules we need to follow
- Clear the space around the indoor unit, or where it will go
- Mention any parking restrictions near the property
Getting a quote
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, you get a fixed price before any work is booked.
Advice
Air source heat pumps in Markyate, done properly
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems do not heat hot water, so you will need another way to do that. If the problem is wanting to stop using oil, LPG or gas for heating and an oil, LPG or gas boiler near the end of its life, we can help.
For a house near Markyate, space outside is rarely the problem, so the main questions are heat loss, radiators and the electrics.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Heat pumps in Markyate: local notes
The centre of Markyate lies within the Markyate Conservation Area. About 42 listed entries lie within half a mile of central Markyate, Church of St. John the Baptist (grade II*) among them. Where a home is affected, the outdoor unit position is settled with Dacorum council, usually the planning authority here before the heat pump design is finished. Markyate is about 28 miles from central London, well within the area we cover from our base in East Grinstead.
A heat loss calculation decides the size of heat pump your home needs.

Common problems we fix in Markyate
For homes with no mains gas, heated by oil or LPG, a heat pump is well worth considering. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas where the home is eligible.
If any of these sounds familiar, it’s worth a diagnosis:
- Plans to switch to electric heating with a heat pump
- Questions about where the outdoor unit can go
- Replacing a combi boiler with a heat pump
If your home is one of the older properties near Markyate Methodist Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
Questions to ask before you book
- If the quote is based on a survey, pictures or a diagnosis
- What happens if the job turns out to be different on the day
- What’s in the price and what isn’t
When it’s something else
A few issues sit outside what this work can do:
- Planning approval where permitted development doesn’t apply
- Promising eligibility for the Boiler Upgrade Scheme
- Tax advice on your own circumstances
Not sure which it is? You can phone 07833 053749, or email if that’s easier and we will tell you honestly before booking.

Safe owner checks
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.

Your questions about air source heat pumps in Markyate
Do you cover smaller places like Markyate?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is the heat pump grant available in Markyate?
Yes, if the home and the heat pump meet the scheme’s rules: Markyate is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. The installer applies, and we are MCS certified.
How long will it take to install a heat pump?
As a guide, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. We plan the work so you’re without heating for as little time as possible and agreed before we start.
Does servicing affect my warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before booking anyone, and we are happy to show ours.
Which brands do you work with?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
