About our air source heat pumps in Amwell
A £2,500 grant is available for some air-to-air heat pumps, with conditions. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home; adding it alongside a boiler does not qualify. The work covers hot water cylinders, radiator systems and air-to-water heat pumps, and common reasons people get in touch are not knowing whether a grant applies and working out where a cylinder could go.
For a home around Amwell that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
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 so it’s to hand next time.

What air source heat pumps can’t fix
Air source heat pumps can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- Getting planning permission or listed building consent on your behalf
- Disconnecting or servicing a gas boiler
- Tax rulings, which only HMRC can give
If in doubt, give us a ring on 07833 053749 or fill in the contact form and we will say what we think.

Radiators and underfloor heating
At lower water temperatures, radiators give out less heat, and the survey checks each one.

Let and managed properties
Records are where property maintenance often slips. Each visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
If you look after several properties, we can quote and plan the work across all of them. Every address has its own paperwork, so the files stay tidy.
Air source heat pumps around Amwell
About 69% of households live in detached or semi-detached houses, according to the 2021 Census. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Older homes near St Helen's Church may need extra checks for planning and heat loss before a heat pump is designed. Childwickbury Manor, roughly 2.6 miles south-west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Questions from Amwell
Is Amwell 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.
Can I fit a heat pump in Amwell without planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Amwell is in the Amwell 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 the local planning authority (for Amwell, normally St Albans City council) first.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
What’s the price of a heat pump installation?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. The final price depends on the heat loss survey, the radiators and the cylinder and the quote is fixed.
What’s the difference between air-to-water and air-to-air heat pumps?
It depends on your home, your heating and whether you want cooling. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are also Checkatrade members.
The process
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we have done. Seeing the property in pictures first means the trip to Amwell can be planned properly.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- The system is commissioned and registered under MCS, and we show you how to use it.
Preparing for the visit
- Make sure someone can let us in at the agreed time
- Tell us about any building rules, permits or sign-in
- Make sure we can reach the consumer unit or fuse board

VAT is set out clearly on every quote, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. For a fixed-price quote, call us on 07833 053749, or email if that’s easier.
