Your questions about air source heat pumps in Friday Street
Will you come out to Friday Street?
Yes. Friday Street is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Can I fit a heat pump in Friday Street without planning permission?
That depends on the building and where the outdoor unit goes. Central Friday Street is a short walk from the Friday Street 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 Mole Valley council, typically the authority for Friday Street.
Will skipping a service affect the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
Do you offer emergency call-outs?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
Who is responsible for leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Can I do the refrigerant work myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
About our air source heat pumps in Friday Street
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. That follows HMRC Notice 708/6, and it does not apply to businesses. For air-to-air systems, we confirm the VAT on your quote. This is general information, not tax advice. If the problem is deciding on the outdoor unit position and choosing between air-to-water and air-to-air, we can sort it out.
Older and listed homes in villages like Friday Street need extra care, and permitted development does not cover listed buildings, so we check consent first.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Owner checks or an engineer?
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.
Why act early in Friday Street
The extra £1,500 for homes heated by oil or LPG with no mains gas is available until March 2027. If that applies to you, it’s worth asking about sooner rather than later. Waiting rarely makes an air conditioning problem smaller.
The cost depends on the type of system and how many units are involved, the access and what the work involves. We give you a fixed price before we start, so there are no surprises.

Different systems, different jobs
Radiators and underfloor heating
At lower water temperatures, radiators give out less heat so we check them against each room’s heat loss.
Hot water cylinders
Hot water from an air-to-water system is stored in a cylinder. The survey looks at where it can go particularly in homes with a combi boiler.

Homes in Friday Street and heat pumps
Valuation Office Agency council tax records put about 40% of homes in Friday Street and the neighbourhoods around it before 1919, and the 2021 Census found about 76% of households in detached or semi-detached houses. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
If your home is one of the older properties near Church of St James, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Polesden Lacey lies about 4.2 miles north. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

The process
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you do not need a separate electrician for the electrical side. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. For a place like Friday Street, the timing is set with you and the travel is our side of the planning.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Commissioning, MCS certification and a handover of the controls finish the job.
Before we arrive
- Let us know where the consumer unit is
- Make sure someone can let us in at the agreed time
