What a heat pump looks like in Greywell
The last census (2021) found about 72% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is one of the older properties near Church of St Mary the Virgin, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Air source heat pumps in Greywell, done properly
We install air source heat pumps in Greywell and across Hampshire, and we are MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We will explain which type fits your home and why. We’re often asked to deal with finding a place for the outdoor unit and replacing a combi boiler with a heat pump, on air-to-air heat pumps, hot water cylinders and radiator systems.
If your home in or near Greywell is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

What owners can safely do
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Greywell: your questions answered
Do you cover smaller places like Greywell?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Is a heat pump in Greywell permitted development?
That depends on the building and where the outdoor unit goes. Central Greywell 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 Hart council, typically the authority for Greywell.
Who is responsible for leak checks?
Responsibility is shared between the operator, typically 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 every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
When will I hear back?
You will hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
How much time does a heat pump install need?
An installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We confirm the timing after the survey, and you can call 07833 053749 or use the quote form to book it.
Why it’s worth doing now in Greywell
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. Dealing with it now is usually simpler than a breakdown later.
Several rooms, units or sites on one quote can make for a more efficient booking. Mention every unit or room you need covered, and you will get one fixed price.

The process
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, and that takes a few days on site, depending on the cylinder, the radiators and the pipework involved. A note on how to find the property and where to park makes a visit to Greywell easier.
- We start with your plans and the property.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- The system is installed and connected to the controls.
- We commission it, complete the MCS certificate and show you how to use it.
Preparing for the visit
- Plan for pets to be kept clear during the visit
- Name a contact who can meet us at the agreed time
- Find the manual or the paperwork for the system, if you have it
Get a fixed-price quote
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
Advice
When it’s something else

A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
