About our air source heat pumps in Hamsey Green
A £2,500 grant is available for some air-to-air heat pumps, with conditions. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. If the problem is replacing a combi boiler with a heat pump and wanting to stop using oil, LPG or gas for heating, we can help.
If your home in or near Hamsey Green is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork, because it helps with any later warranty question.

Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases, and we explain which fits your home. Getting the date in early helps for a place like Hamsey Green.

Air source heat pumps in Hamsey Green: the local picture
VOA council tax data date about 43% of homes in the Hamsey Green area to the post-war years, 1945 to 1972, and about 83% of households live in detached or semi-detached houses, according to the 2021 Census. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Houses normally have space for an outdoor unit and a hot water cylinder.
If your home is one of the older properties near St Antony, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

How it works
Where something has to be switched off during the work, we agree it with you first so it does not catch you out. In a business, work can often be done one area at a time. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. We plan the trip to Hamsey Green around you.
- We talk through your home, your current heating and what you want from a heat pump.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Preparing for the visit
- Arrange for someone to be there to let us in
- Plan for pets to be kept clear during the visit
- Let us know where the consumer unit is

Advice
Common problems we fix in Hamsey Green
Some people want to move away from burning fossil fuels at home. A heat pump runs on electricity and takes heat from the outside air, which is why it fits that aim.
Keep an eye out for these signs:
- Questions about where the outdoor unit can go
- Checking eligibility for a heat pump grant
- Ageing boilers that will need replacing
If your home is listed, like Addington Palace about 2.8 miles north, listed building consent comes before any heat pump work.
Comparing quotes
- Who does the electrical work, and whether they can certify it
- Whether they hold F-Gas company certification, not just individual qualifications
- What the manufacturer’s warranty covers and for how long
Hamsey Green questions
Do you cover smaller places like Hamsey Green?
Yes, and the size of the place makes no difference to how we work. A few pictures and the postcode are enough to get things started.
Do I need planning permission for a heat pump in Hamsey Green?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of Hamsey Green holds about 3 listed buildings and structures. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Hamsey Green, normally Croydon council).
How do you keep the place clean during the work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
When will I hear back?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Do I get paperwork after the visit?
Yes. Every visit is written up, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Can I get the Boiler Upgrade Scheme grant?
Eligibility depends on the property and the scheme rules. The scheme gives £7,500 for eligible air-to-water or ground source systems, and £2,500 for air-to-air only under strict conditions, and we check before you commit.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
