Air source heat pumps in Wandsworth, done properly
Many air source heat pumps can be installed as permitted development in England, without a planning application. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. If the problem is finding a place for the outdoor unit and checking eligibility for a heat pump grant, we can help.
For flats in Wandsworth, the lease, the freeholder and the rules for flats all come into it. Permitted development limits are different for flats, so we check the position before we design.
Warranty periods vary by brand and by product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Let and managed properties
Records are where property maintenance often slips. Each visit is written up, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Facilities teams in offices, schools and public buildings book us too across Greater London. Work can be phased by floor, zone or building to keep disruption down.
System by system
Air-to-air heat pumps
Air-to-air heat pumps warm rooms through indoor units and can cool them in summer. They do not heat hot water, so that has to come from elsewhere.
Hot water cylinders
An air-to-water heat pump heats hot water through a cylinder. Space for the cylinder is part of the survey, especially if you have a combi boiler.
What owners can safely do
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.

What else we do in Wandsworth
Air source heat pumps in Wandsworth: the local picture
VOA council tax data put about 49% of homes across Wandsworth and its surrounding area before 1919, and the last census (2021) found about 68% of households live in flats. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. 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.
If your home is one of the older properties near St Anne's Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. If you live near Wandsworth Town station, the survey compares air-to-water and air-to-air for your home before anything is quoted.

Your questions about air source heat pumps in Wandsworth
Do I need planning permission for a heat pump in Wandsworth?
There’s no single answer: the building and the outdoor unit position decide it. Central Wandsworth is a short walk from the Wandsworth Town Conservation Area. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Wandsworth council, which is usually the planning authority for Wandsworth first.
Can I get the Boiler Upgrade Scheme grant in Wandsworth?
Yes, the scheme covers homes in England, including Wandsworth, if they qualify. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You don’t apply yourself: the MCS certified installer does, which is us.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and we hold it.
What does an air-to-water heat pump cost?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll tell you what to do first.
Do you work in Wandsworth?
Yes. Our engineers work in Wandsworth, as part of our area across London and the South East. Our base is in East Grinstead, West Sussex.
What we do, step by step
Where something has to be switched off during the work, we agree it with you first so it does not catch you out. For businesses, we can typically work room by room or zone by zone. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. Before a visit in Wandsworth, we ask where the van can stop and how we reach the outdoor unit.
- You tell us about the home and what you want from a heat pump.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.

- The job ends with commissioning, the MCS certificate and a walk through the controls.
How to prepare

“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.”
