Air source heat pumps in Mitcham
In England, an air source heat pump on a house can often go in under permitted development rights. 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 look at the planning position for your home during the survey. If you are dealing with wanting to stop using oil, LPG or gas for heating and questions about the Boiler Upgrade Scheme, we can sort it out.
In a London area like Mitcham, many homes are flats or terraces with little outside space, which affects which heat pump suits. An air-to-water system needs space outside and normally a hot water cylinder inside, while air-to-air units take less room.
Warranty periods vary by brand and by product. For example, 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.

Fixed-price quotes for air source heat pumps in Mitcham
You’ll get a fixed price before work begins. It’s based on:
- How easy the units are to reach
- The size of the job
- Whether the existing supply is suitable
The cost depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. You get a fixed price before we start, so there are no surprises.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- Photos showing the indoor unit and the space around it
- Any error code or flashing light on the display
- The fuse board and where it is in the property
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To get going, call us on 07833 053749.
What a heat pump looks like in Mitcham
VOA council tax data show about 49% of homes in the Mitcham area date from 1919 to 1939, and the last census (2021) found about 43% of households in terraced houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door. In London, outside space and the rules for flats often decide which kind of heat pump suits.
With Southside House about 3.6 miles west, it’s worth asking whether your own home is listed before planning a heat pump. If you live near Mitcham Eastfields station, the survey compares air-to-water and air-to-air for your home before anything is quoted.

How the job changes from property to property
Air-to-water heat pumps
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. Eligible homes in England and Wales can get a £7,500 Boiler Upgrade Scheme grant towards it and the installer applies.
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger so we check them against each room’s heat loss.
How the visit works
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. A note on parking and access helps us plan a visit to Mitcham.
- We start with your plans and the property.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Let us know if the building has a permit or sign-in process

Common questions in Mitcham
Does the Boiler Upgrade Scheme cover homes in Mitcham?
Yes, the scheme covers homes in England, including Mitcham, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. The installer applies, and we’re MCS certified.
Can you fit air conditioning in a London flat in Mitcham?
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.
How much time does a heat pump install need?
The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. The survey lets us set a firm programme, so ring us on 07833 053749 or send an email to arrange one.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
How quickly will you reply?
We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before any work starts, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Whose job is it to check the system for leaks?
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 will work out which band applies to yours.
Leave it or put it right?
Planning rules have specific conditions. We look at the planning position early, so there are no surprises covering listed buildings, conservation areas and any Article 4 direction. Allow time for any approvals your building in Mitcham needs.
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.
