How we handle air source heat pumps in Much Hadham
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. The work covers air-to-water heat pumps, hot water cylinders and radiator systems, and common reasons people get in touch are checking emitters for a heat pump and checking whether planning permission is needed.
Space for an outdoor unit is rarely an issue near Much Hadham, so the design comes down to heat loss, radiators and hot water.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Questions from Much Hadham
Can I fit a heat pump in Much Hadham without planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Much Hadham sits inside the Much Hadham Conservation Area. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with East Hertfordshire council, which is normally the planning authority for Much Hadham first.
Is Much Hadham within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you have a 24/7 line?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we will talk you through the next steps.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. With air-to-air, hot water needs another source and the survey helps decide.
What VAT do I pay on a heat pump?
For homes, currently none: until 31 March 2027 the rate is 0% in residential accommodation, then 5%. The relief is not available to businesses, and with air-to-air we confirm the VAT on the quote. This is general information, not tax advice.
How do you keep the place clean during the work?
Protection goes down first: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Will my radiators work with a heat pump?
We find out during the survey. Where a radiator is already large enough, it stays and any changes are in the quote.
System by system
Outdoor unit position and planning
Under permitted development, the outdoor unit must be 1.5 m³ or less and must meet MCS 020(a) and not be used solely for cooling. Listed building curtilages are excluded.
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger so we check them against each room’s heat loss.
Rented and managed buildings
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Keeping records across a portfolio is half the battle. Each visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.

What we do, step by step
Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, and that takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Pictures of the space and where the outdoor unit could go let us plan the work in Much Hadham.
- We start with your plans and the property.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We explain which type of heat pump suits the home and whether a grant could apply.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Getting ready for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Keep pets and children away from the work area
- Make sure we can reach the outdoor unit, or where it will go

Pricing air source heat pumps in Much Hadham
Jobs vary more than people expect. What affects the quote:
- How easy the units are to reach
- Whether it’s a one-off job or part of a maintenance contract
- What electrical work the job needs
Several rooms, units or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed price.
Before you get in touch
You do not need the technical terms. It helps if you can send:
- A few pictures of the room and the wall the unit is on, or will go on
- A close-up of the unit’s label showing the model number
- Any error code or flashing light on the display
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
