Heat pumps in The Wrythe: local notes
About 40% of homes in the The Wrythe area were built between the wars, according to the Valuation Office Agency’s council tax figures. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Period properties close to Bishop Andrewes Church can suit a heat pump, though insulation and any heritage protection are checked first. Nonsuch Mansion lies about 2.9 miles west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
The Wrythe is about 7 miles south of Stockwell, in Greater London. Whatever kind of property you have in The Wrythe, our engineers can help with air source heat pumps.

Air source heat pumps in The Wrythe, done properly
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 the quote sets it out. Typical jobs include a boiler that’s getting old and deciding on the outdoor unit position, across homes heated by oil, LPG or gas, air-to-air heat pumps and underfloor heating.
Homes in The Wrythe are often flats and terraces, where outside space is limited, which affects which heat pump suits. An air-to-water system needs space outside and typically a hot water cylinder inside, while an air-to-air system needs less space.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

More services for The Wrythe
What the work involves, system by system
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, so radiator sizes matter.
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. Noise is part of the MCS 020(a) check, so we consider nearby homes too.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Look at insulation alongside the heat pump
- Ask about the grant before you commit
- Check what your manufacturer’s warranty asks of you
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork for future reference.
Have the system serviced regularly. Your manufacturer’s warranty terms may say something about servicing.
Landlords, agents and facilities managers
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
Portfolio owners often want one contractor and one number. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
What happens on the day
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we clear up before we go. Parking bays, permits and roof or balcony access are the first things we ask about in The Wrythe.
- First we talk through the property and the current system.
- 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.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure someone can let us in at the agreed time
- Dig out any previous service or F-Gas records

Advice
Questions from The Wrythe
Is planning permission needed for a heat pump in The Wrythe?
There’s no single answer: the building and the outdoor unit position decide it. A conservation area takes in the middle of The Wrythe. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where necessary, we check with the planning department at Sutton council, usually the authority for The Wrythe.
Can I get the Boiler Upgrade Scheme grant in The Wrythe?
Yes, the scheme covers homes in England, including The Wrythe, 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. We hold MCS certification, so the application is ours to make for you.
How long will it take to install a heat pump?
It 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. How much of the heating changes decides most of the time, and we confirm the timing with your quote.
Do you offer emergency call-outs?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll talk you through the next steps.
Is there a survey before the work?
Yes. We always look before we price, on a survey, or from your pictures and details where the job is simple. Then you get a fixed-price quote.
Do I get paperwork after the visit?
Yes. You get a written record of every visit, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
What warranty do I get?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition so it’s worth keeping the service records.
