Air source heat pumps for homes and businesses in Dulwich
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. Air-to-air systems do not heat hot water, so you’ll need another way to do that. The work covers underfloor heating, hot water cylinders and air-to-air heat pumps, and common reasons people get in touch are no space for a hot water cylinder and not knowing whether a grant applies.
For flats in Dulwich, the lease, the freeholder and the rules for flats all come into it. The planning rules for flats are stricter than for houses, and we check before designing.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What air source heat pumps can’t fix

- A grant for a home that doesn’t meet the scheme rules
- Improving the building’s insulation
- Tax advice on your own circumstances

- Air-to-water heat pumps
- Hot water cylinders
- Underfloor heating
- Homes heated by oil, LPG or gas
After we have gone
Looking after the system is mostly common sense. Our tips:
- File the MCS certificate safely
- Leave indoor units unobstructed
- Read the manufacturer’s warranty terms for your brand
Now and then in cold weather, the outdoor unit defrosts itself. You might see steam or hear the unit change note, and that’s normal.
Keep the outdoor unit clear of leaves, plants and stored items. It needs good airflow to collect heat from outside, so keep it clear all year.

Dulwich questions
Can I get the Boiler Upgrade Scheme grant in Dulwich?
Dulwich is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
Do I need planning permission for a heat pump in Dulwich?
It depends on the property. The Dulwich Wood Conservation Area takes in the middle of Dulwich. 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 Southwark council, which is typically the planning authority for Dulwich.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Which accreditations do you hold?
We are an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are also Checkatrade members.
Will my radiators work with a heat pump?
Some radiators may be fine as they are, and some may need to be larger. At the lower temperatures a heat pump uses, radiators need more surface so we check every radiator against the room’s heat loss.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
How long does a heat pump installation take?
An installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We confirm the timing after the survey, and you can phone us on 07833 053749 or drop us a line to book it.
Why deal with it now?
For eligible off-gas homes on oil or LPG, an extra £1,500 is on offer until March 2027. For homes that qualify, that is a reason to look into it now. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.
The pipe route, the height of the units and how we reach them can all change the price. We take each of them into account, and the price is fixed before any work starts.

Air source heat pumps around Dulwich
The Valuation Office Agency’s council tax figures put about 73% of homes in and around Dulwich before 1919, and about 54% of households live in flats, according to Census 2021 figures. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Homeowners near West Dulwich station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that. Older homes near Christ's Chapel of God's Gift may need extra checks for planning and heat loss before a heat pump is designed.

How the visit works
Think of the visit in three stages: diagnose, treat 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. Most of the time goes on the middle part, which takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Let us know who controls access to the building in Dulwich, as that saves time on the day.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- 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.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Getting ready for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Clear access to the fuse board
- Make sure someone can let us in at the agreed time
Getting a quote
VAT is set out clearly on every quote, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, phone us on 07833 053749, or email if that’s easier.
