About our air source heat pumps in Leverstock Green
A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. If you are dealing with deciding on the outdoor unit position and deciding which kind of heat pump suits the home, we can help.
Whether a home near Leverstock Green has mains gas makes a difference to the grant. Until March 2027, homes on oil or LPG without mains gas can get an extra £1,500 through the Boiler Upgrade Scheme, for an air source or ground source heat pump.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Managing agents and facilities teams in Leverstock Green
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we are happy to deal with whoever it is.
What happens on the day
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’ve done. Tell us about any gates or steps at your property near Leverstock Green when you book.
- We talk through your home, your current heating and what you want from a heat pump.
- 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.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Make sure we can reach the outdoor unit, or where it will go
- Mention any roof access, ladders or high-level work
- Plan for pets to be kept clear during the visit
Getting a quote
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
Advice
Heat pumps in Leverstock Green: local notes
Valuation Office Agency council tax records date about 66% of homes in the Leverstock Green area to the post-war years, 1945 to 1972. For homes of that age, the survey checks the insulation, the radiators and the hot water setup.
Period properties close to Church of Holy Trinity can suit a heat pump, though insulation and any heritage protection are checked first. If your home is listed, like Batchwood Hall about 3.5 miles east, listed building consent comes before any heat pump work.

Leverstock Green questions
Will you come out to Leverstock Green?
Yes. Leverstock Green is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is a heat pump in Leverstock Green permitted development?
There’s no single answer: the building and the outdoor unit position decide it. Around 8 listed entries sit within 0.5 miles of central Leverstock Green. 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 Leverstock Green, usually Dacorum council) first.
How long will it take to install a heat pump?
A typical installation takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We plan the work so you’re without heating for as little time as possible and agreed before any work starts.
Do you provide F-Gas records?
Yes. You get a written record of each visit, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
Are you F-Gas certified?
As the law requires for refrigerant work, we are an F-Gas certified company. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
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 we explain which suits your home.

Looking after your system
Systems last better with the right care. Here’s what we suggest:
- Find out the grant position at the survey
- Look at insulation alongside the heat pump
- File the MCS certificate safely
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Leave space around the outdoor unit. Airflow is what it runs on so keep it unobstructed.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
