Air source heat pumps in Patchetts Green
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. If the problem is not knowing whether a grant applies and working out where a cylinder could go, we can help.
If your home in or near Patchetts Green is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Looking after it afterwards
To keep the system working properly:
- Clear leaves and debris from the outdoor unit
- Keep to regular servicing
- Look at insulation alongside the heat pump
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork for future reference.
Keep radiators and indoor units unobstructed so the heat can get into the room.
Patchetts Green questions
Is Patchetts Green within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is planning permission needed for a heat pump in Patchetts Green?
That depends on the building and where the outdoor unit goes. The Patchetts Green and Delrow Conservation Area is close to the centre of Patchetts Green. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Hertsmere council, usually the authority for Patchetts Green.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Which type of heat pump is right for my home?
Air-to-water heats radiators or underfloor heating and hot water; air-to-air heats rooms through indoor units and can cool them. With air-to-air, hot water needs another source and the survey helps decide.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
Is there VAT on a heat pump?
For homes, currently none: until 31 March 2027 the rate is 0% in residential accommodation, then 5%. Businesses and hotels pay the standard rate, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice.
Managing agents and facilities teams in Patchetts Green
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to and we will copy in whoever needs it.
The process
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes a few days on site, depending on the cylinder, the radiators and the pipework involved, and we tidy up before we leave. We plan the trip to Patchetts Green around you.
- First we find out about the property, the heating you have now and what you’re hoping for.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Mention any parking restrictions near the property
- Clear the space around the indoor unit, or where it will go
- Let us know if the units are on a roof, a high wall or in a locked area
Ask for a quote
The quickest way to a quote is to send pictures: 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. Tell us the address and what you need, and simple jobs can often be priced without a visit.
Advice
Why it’s worth doing now in Patchetts Green
For eligible off-gas homes on oil or LPG, an extra £1,500 is on offer until March 2027. For homes that qualify, that’s a reason to look into it now. A dirty or faulty system works harder and costs more to run.
Putting several jobs into one visit often makes better use of the time. Mention every unit or room you need covered and we’ll price it together.
