Common questions in Sutton
Can you fit air conditioning in a London flat in Sutton?
Often, yes, but the lease and the freeholder usually have a say. 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 fit a heat pump in Sutton without planning permission?
It depends on the property. Central Sutton sits inside a conservation area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Sutton council, usually the authority for Sutton.
Do you work in Sutton?
Yes. We work across Greater London, Surrey, Kent, East and West Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Sutton included.
Will skipping a service affect the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
Does the grant cover air-to-air heat pumps?
It can, as long as the system takes over the heating completely. The £2,500 applies when it replaces the fossil-fuel heating, covers the full heating demand, is fitted by an MCS certified installer and serves a home. Fitted alongside a boiler, it won’t qualify.
Are my radiators big enough for a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat, and the survey checks each one.
About our air source heat pumps in Sutton
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. The work covers air-to-water heat pumps, hot water cylinders and homes heated by oil, LPG or gas, and common reasons people get in touch are no space for a hot water cylinder and questions about listed buildings or conservation areas.
In a flat in Sutton, the lease and the freeholder usually decide where a heat pump can go. Permitted development limits are different for flats, so we check the position before we design.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

What we are called out for in Sutton
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. The Boiler Upgrade Scheme includes an extra £1,500, until March 2027, for air source or ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.
It’s time to call us if you’re dealing with:
- Questions about where the outdoor unit can go
- Deciding which kind of heat pump suits the home
- Working out where a cylinder could go
Nonsuch Mansion, roughly 1.6 miles west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.
Questions to ask before booking
- What paperwork you’ll receive afterwards
- Whether a new circuit is included and who certifies it
- Whether they looked at the job before pricing it

The process
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. A few pictures of the room, the outside wall and the fuse board help us plan a job in Sutton.
- 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.
- We explain which type of heat pump suits the home and whether a grant could apply.
- Installation follows on the agreed dates.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
How to prepare
- Tell us about parking and loading
- Make sure we can reach the outdoor unit, or where it will go
- Let us know where the consumer unit is

If you look after several properties, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so the files stay tidy.
Air source heat pumps around Sutton
The 2021 Census found about 59% of households live in flats. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Live in one of the older houses around St Nicholas Church? Expect the survey to look closely at heat loss and at the building’s planning status.

Looking after your system

- File the MCS certificate safely

- Don’t block radiators or indoor units with furniture
Equipment warranties come from the manufacturer. We go through the conditions with you, including any servicing they ask for.
Let the heat pump run steadily rather than switching it on and off as explained at handover.
