Air source heat pumps in Deptford
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. If the problem is no space for a hot water cylinder and finding a place for the outdoor unit, we can sort it out.
In a flat in Deptford, the lease and the freeholder typically decide where a heat pump can go. The planning rules for flats are stricter than for houses, and we check before designing.
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.

When to call us in Deptford
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.
Keep an eye out for these signs:
- Checking eligibility for a heat pump grant
- Radiators that may be too small for a heat pump
- Replacing a combi boiler with a heat pump
Older homes near St. Paul's may need extra checks for planning and heat loss before a heat pump is designed.

What owners can safely do
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.

How it works
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 everything is tested, recorded and explained. The middle part takes longest, which takes a few days for most air-to-water installations, with air-to-air systems often quicker. Some blocks in Deptford need contractor details in advance, so tell us what your building needs.
- It starts with a conversation about the home, the existing heating and your plans.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Mention any parking restrictions near the property
- Arrange for someone to be there to let us in
- Clear a path to the units and the space around them

Your questions about air source heat pumps in Deptford
Will a heat pump in Deptford need planning permission?
That depends on the building and where the outdoor unit goes. The centre of Deptford is in the Deptford High Street Conservation Area. 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 Lewisham council, which is normally the planning authority for Deptford.
Is the heat pump grant available in Deptford?
Yes, the scheme covers homes in England, including Deptford, if they qualify. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. We hold MCS certification, so the application is ours to make for you.
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. Air-to-air doesn’t heat hot water, and we explain which suits your home.
Why does F-Gas certification matter?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
When will I hear back?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
Air source heat pumps in Deptford: the local picture
About 34% of homes in Deptford and the neighbourhoods around it have been built since 2000, according to VOA council tax data, and the last census (2021) found about 79% of households live in flats. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. A flat may have no room for a hot water cylinder, and the freeholder typically has a say on the outdoor unit, which can tip the choice towards air-to-air. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
For a home near Deptford station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.

Let and managed properties
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we will keep everyone informed.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We’re happy to deal with either side, and the paperwork can go to both.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
