Air source heat pumps in Cheam
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. With air-to-air, hot water has to come from something else. Common call-outs are for moving away from fossil-fuel heating and an oil, LPG or gas boiler near the end of its life, across hot water cylinders, air-to-air heat pumps and homes heated by oil, LPG or gas.
In a flat in Cheam, the lease and the freeholder usually decide where a heat pump can go. The planning rules for flats are stricter than for houses, and we check before designing.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Air source heat pumps in Cheam: the local picture
About 63% of households live in detached or semi-detached houses, according to the 2021 Census. Houses typically have space for an outdoor unit and a hot water cylinder. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Live in one of the older houses around Church of St Andrew? Expect the survey to look closely at heat loss and at the building’s planning status.

What else we do in Cheam
Signs you need air source heat pumps in Cheam
Air-to-air systems interest people who want cooling in summer as well as heating. They heat rooms through wall, floor or ceiling units and switch to cooling in warm weather. The grant only applies in some cases, so we check first.
If any of these sounds familiar, it’s worth a diagnosis:
- Not knowing whether a grant applies
- No space for a hot water cylinder
- Moving away from fossil-fuel heating
Nonsuch Mansion, roughly 1 mile north-west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.
Before you book anyone
- Whether they hold F-Gas company certification, not just individual qualifications
- What’s in the price and what isn’t
- The make and model of any parts or equipment being quoted
What we do, step by step
Each visit follows the same order: agree the plan on site, put the dust sheets down, do the work, check the system and talk you through it. On site, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. Some blocks in Cheam need contractor details in advance, so tell us what your building needs.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Let us know where the consumer unit is
- Unlock any gate, garage or side passage we need
- Move furniture away from the wall where we’ll be working
Ask for a quote
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, call us on 07833 053749.

Your questions about air source heat pumps in Cheam
Will a heat pump in Cheam need planning permission?
That depends on the building and where the outdoor unit goes. A conservation area takes in the middle of Cheam. 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 the planning department at Sutton council, typically the authority for Cheam first.
Can I have air conditioning in a flat in Cheam?
Normally, yes, though leaseholders normally need the freeholder’s agreement. 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.
Should I choose air-to-water or air-to-air?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms. The survey helps decide. We install both types.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
Do you look at the job first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it, and the quote is based on that.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Does servicing affect my warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
Looking after it afterwards
So the system stays in good health:
- Let the heat pump run steadily, as set up at handover
- Seal draughts where you can
- Keep to regular servicing
Handover includes the controls and how to get the best from a heat pump. Steady running suits a heat pump better than switching on and off, and we will explain the settings for your home.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.
Why deal with it now?
If the emitters can’t give out enough heat, some rooms will not get warm enough. Checking and upsizing them as part of the installation avoids that. Approvals for flats in Cheam can take longer than the install itself.
What you pay reflects the actual work. That is why we look at the job first, from pictures or on a survey, and the price is agreed before work begins.
