How we handle air source heat pumps in North Cheam
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home; adding it alongside a boiler does not qualify. If the problem is replacing a combi boiler with a heat pump and questions about listed buildings or conservation areas, we can sort it out.
Homes in North Cheam 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 typically a cylinder, while an air-to-air system needs less space.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

After we’ve gone
So the system stays in good health:
- Do not block radiators or indoor units with furniture
- Ask about the grant before you commit
- Know the servicing conditions in your warranty
Should you have questions after the install, phone us on 07833 053749 or use the quote form and we will look into it. Annual servicing helps keep the system working well.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.
Fixed-price quotes for air source heat pumps in North Cheam
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How far the pipework has to run, and where
- Access, including height, roofs and ladders
- The brand, model and parts involved
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you are unsure, ring us on 07833 053749 or use the quote form and we’ll give you an honest view and a fixed price.
What we need to know
Before you ask for a quote, gather:
- Where the outdoor unit is, or where you’d like it
- Wide photos of the room or the existing unit
- Any error code or flashing light on the display
Here’s what helps us quote: the address and the type of property, photos of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Once you have those, give us a ring on 07833 053749 or send an email.
How it works
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, which takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. In a London area like North Cheam, parking and access are worth sorting out before the day.
- We find out about your home and the heating you have now.
- We measure heat loss for every room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- Cost, grant and VAT appear on one fixed-price quote.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Let us know where the consumer unit is
- Unlock any gate, garage or side passage we need
- Mention any managing agent or landlord rules we need to follow
Getting a quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Common questions in North Cheam
Do I need permission to put air conditioning in my flat in North Cheam?
Typically, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Can I get the Boiler Upgrade Scheme grant in North Cheam?
Yes, the scheme covers homes in England, including North Cheam, if they qualify. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. As an MCS certified installer, we apply for it on your behalf.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
How quickly will you reply?
You’ll hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Are you F-Gas certified?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Does servicing affect my warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Different systems, different jobs
Air-to-water heat pumps
Air-to-water systems take heat from the air and put it into your central heating and hot water. It takes over from the boiler, and is MCS certified when we install it.
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. We also consider neighbours and noise, as MCS 020(a) includes a noise check.

What else we do in North Cheam
Air source heat pumps in North Cheam: the local picture
VOA council tax data show about 58% of homes across North Cheam and its surrounding area date from 1919 to 1939, and Census 2021 figures found about 35% of households in terraced houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Older homes near St Oswald Church may need extra checks for planning and heat loss before a heat pump is designed. With Nonsuch Mansion about 1 mile south, it’s worth asking whether your own home is listed before planning a heat pump.
