Air source heat pumps in Fields End
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. The technology is close to air conditioning, which is why we install both and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. We are often asked to deal with questions about the Boiler Upgrade Scheme and wanting to stop using oil, LPG or gas for heating, across radiator systems, homes heated by oil, LPG or gas and underfloor heating.
In a place like Fields End, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so we check consent first.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Heat pumps in Fields End: local notes
About 73% of homes in the Fields End area date from 1945 to 1972, according to VOA council tax data, and the last census (2021) found about 52% of households in terraced houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important. At about 25 miles from central London, Fields End sits inside the area we cover across London and the South East.
Every heat pump design starts with a room-by-room heat loss calculation. Older homes near St Alban's Church may need extra checks for planning and heat loss before a heat pump is designed.

- Disconnecting or servicing a gas boiler
- Improving the building’s insulation
- Planning approval where permitted development doesn’t apply

What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. The middle part takes longest, which takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Seeing the property in pictures first means the trip to Fields End can be planned properly.
- We talk through your home, your current heating and what you want from a heat pump.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- 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
- Let us know where we can park and unload
- Make sure someone can let us in at the agreed time
- Have the make and model of any existing unit to hand

Photos are enough for some jobs; others need a visit first. 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.

Common questions in Fields End
Is Fields End in your area for air source heat pumps?
Yes, Fields End is within the area we cover. Just give us a ring on 07833 053749, or email if that’s easier with a few details.
Can I get the Boiler Upgrade Scheme grant in Fields End?
Yes, if the home and the heat pump meet the scheme’s rules: Fields End is in England, where it applies. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. As an MCS certified installer, we apply for it on your behalf.
Will my radiators work with a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How much time does a heat pump install need?
As a guide, it takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. We plan the work so you are without heating for as little time as possible, and we explain it in advance.
Should I choose air-to-water or air-to-air?
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 emergency call-outs?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we’ll talk you through the next steps.
Why act early in Fields End
From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. It’s a date to bear in mind when planning alongside your own plans for the property. An early booking makes the visit to Fields End easier to arrange.
