Air source heat pumps for homes and businesses in Enfield Lock
A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. Common call-outs are for ageing boilers that will need replacing and working out where a cylinder could go, on hot water cylinders, air-to-air heat pumps and radiator systems.
A terrace in Enfield Lock shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Heat pumps in Enfield Lock: local notes
About 36% of homes across Enfield Lock and its surrounding area were built between the wars, according to Valuation Office Agency council tax records, and the 2021 Census found about 35% of households in terraced houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Period properties close to Ss Peter and Paul Church can suit a heat pump, though insulation and any heritage protection are checked first. For a home near Enfield Lock station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.

How the visit works
We book the visit for a day and time that suit you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. For a job in Enfield Lock, tell us about parking, permits and access to the building when you get in touch.

Why deal with it now?
Radiators that are too small for a heat pump’s lower flow temperature leave rooms cool. Checking and upsizing them as part of the installation avoids that. Booking in spring means a home or office in Enfield Lock is ready before the first hot week.
Our prices page shows typical ranges, but each job is priced on what it involves. For a fixed-price quote, call 07833 053749 or use the quote form, and we’ll talk you through it.

Looking after it afterwards
To keep the system working properly:
- Know the servicing conditions in your warranty
- Keep the outdoor unit clear all year
- Avoid switching the heat pump on and off often
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes, and that’s normal.
Keep radiators and indoor units unobstructed, as the system relies on them giving out heat.
FAQs for Enfield Lock
Do I need permission to put air conditioning in my flat in Enfield Lock?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Can I fit a heat pump in Enfield Lock without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. A conservation area takes in the middle of Enfield Lock. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Enfield Lock, usually Enfield council).
Can landlords and managing agents book you?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Enfield Lock and across Greater London. Let us know who the records should go to.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Is there a Boiler Upgrade Scheme grant for air-to-air?
Yes, but only where it becomes the home’s main heating. An air-to-air heat pump can get £2,500 if it replaces the fossil-fuel heating, meets the full heating demand, is fitted by an MCS certified installer and is in a home. Fitted alongside a boiler, it won’t qualify.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.
Am I eligible for a heat pump grant?
Possibly. The scheme runs in England and Wales and pays £7,500 towards an eligible air-to-water or ground source heat pump, or £2,500 for an air-to-air system that meets stricter conditions. Homes heated by oil or LPG with no mains gas can get an extra £1,500 towards an air source or ground source heat pump until March 2027. The survey is where we check your home against them.
