Air source heat pumps for homes and businesses in Picketts Lock
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. The work covers underfloor heating, air-to-water heat pumps and hot water cylinders, and the jobs we see most are an oil, LPG or gas boiler near the end of its life and checking whether planning permission is needed.
Terraced houses in a London area like Picketts Lock can suit a heat pump well, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

What affects the cost of air source heat pumps
Every job gets its own quote. This is what makes a difference:
- Access, including height, roofs and ladders
- What state the existing equipment is in
- The number of rooms, units or zones
Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we will explain each part.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- The rating plate or label on any existing unit
- Photos showing the indoor unit and the space around it
- The remote or wall controller showing any error
To get a fixed-price quote, call 07833 053749 or use the quote form and tell us about the property and what you need. A few pictures make it quicker. We reply to enquiries the same working day.
Looking after it afterwards
Simple habits make a real difference. Our advice:
- Know the servicing conditions in your warranty
- Store the MCS certificate and warranty documents together
- Keep to regular servicing
Once commissioned, we register the installation with MCS and give you the certificate. File it with the warranty documents for future reference.
Keep insulation and draught-proofing in good order because it reduces the heat the system needs to supply.
Landlords, agents and facilities managers
Facilities teams in offices, schools and public buildings book us too across Greater London. Larger buildings can be done in stages around the people who use them.
Records are where property maintenance often slips. Each visit is written up, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
Air source heat pumps in Picketts Lock: the local picture
In London, outside space and the rules for flats often decide which kind of heat pump suits.
Period properties close to All Saints' Church can suit a heat pump, though insulation and any heritage protection are checked first. Bruce Castle lies about 2.6 miles south-west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

The work 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. Parking bays, permits and roof or balcony access are the first things we ask about in Picketts Lock.

Picketts Lock questions
Will a heat pump in Picketts Lock need planning permission?
The answer turns on the property and where the outdoor unit would sit. A conservation area takes in the middle of Picketts Lock. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where needed, we check with the local planning authority (for Picketts Lock, typically Enfield council).
Does the Boiler Upgrade Scheme cover homes in Picketts Lock?
Yes, if the home and the heat pump meet the scheme’s rules: Picketts Lock is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You don’t apply yourself: the MCS certified installer does, which is us.
Do I need new radiators for 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.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Keep every service record either way.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll agree what happens next.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is recorded and F-Gas records kept where they apply.
How long will it take to install a heat pump?
Expect it to take several days for an air-to-water system with a new cylinder, less for an air-to-air system. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
