About our air source heat pumps in Southwark
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. With air-to-air, hot water has to come from something else. Typical jobs include choosing between air-to-water and air-to-air and plans to switch to electric heating with a heat pump, on air-to-water heat pumps, air-to-air heat pumps and underfloor heating.
Homes in Southwark are often flats and terraces, where outside space is limited, which affects which heat pump suits. Air-to-water needs room for the outdoor unit and usually a cylinder, while air-to-air units take less room.
Aftercare is simple, and most of it is in the manual: 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.

Homes in Southwark and heat pumps
About 46% of homes in and around Southwark have been built since 2000, according to VOA council tax data, and about 92% of households live in flats, according to the last census (2021). Better insulated, newer homes are often a good match for a heat pump. A flat may have no room for a hot water cylinder, and the freeholder usually 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 Elephant & Castle station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.

Southwark: your questions answered
Can you fit air conditioning in a London flat in Southwark?
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.
Do I need planning permission for a heat pump in Southwark?
It depends on the property. Central Southwark sits inside the Liberty of the Mint Conservation Area. 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 can’t face a road. Where necessary, we check with the local planning authority (for Southwark, usually Southwark council).
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Do you offer emergency call-outs?
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 will agree what happens next.
How much VAT is charged on a heat pump in a home?
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5%. Businesses pay the standard rate. This is general information, not tax advice.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
What we do, step by step
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. Let us know who controls access to the building in Southwark, 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.
- 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.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Tell us about parking and loading
- Name a contact who can meet us at the agreed time

Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
Related advice
What happens if it’s left?
The two types suit different homes and needs. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases, and we explain which fits your home. In London, hot spells can bring a rush of calls, so planning the work in Southwark before summer avoids the wait.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you are not sure what’s needed, call us on 07833 053749 or fill in the contact form for straight advice and a fixed price.

Keeping the system healthy
To keep the system working properly:
- Use the settings explained at handover
- Leave indoor units unobstructed
- Know the servicing conditions in your warranty
Handover includes the controls and how to get the best from a heat pump. Heat pumps tend to work best running steadily rather than in short bursts so we set the controls up with you.
Leave space around the outdoor unit. It needs good airflow to collect heat from outside, so keep it clear all year.

Common problems we fix in Southwark
An ageing boiler is often the moment people start thinking about a heat pump. Planning the change before the boiler fails gives you time to survey, design and apply for any grant instead of making a rushed decision when the heating stops.
Look out for any of the following:
- Choosing between air-to-water and air-to-air
- Checking eligibility for a heat pump grant
- Replacing a combi boiler with a heat pump
Historic houses such as Mansion House, about 0.9 miles north, are a reminder that listed homes need consent before a heat pump goes in.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
