Air source heat pumps in Castle Green
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 doesn’t apply to businesses. For air-to-air systems, we confirm the VAT on your quote. Please treat this as general information rather than tax advice. The work covers hot water cylinders, air-to-air heat pumps and air-to-water heat pumps, and people most often call us about checking emitters for a heat pump and an oil, LPG or gas boiler near the end of its life.
A terrace in Castle Green shares walls with its neighbours, which helps keep heat in, as long as there’s a sensible spot for the outdoor unit and its noise is checked against the MCS planning standard.

Air source heat pumps around Castle Green
About 55% of homes in the Castle Green area were built between the wars, according to VOA council tax data, and Census 2021 figures found about 49% of households in terraced houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. In a terrace, the outdoor unit position and the MCS noise check need particular care. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Live in one of the older houses around St John the Divine? Expect the survey to look closely at heat loss and at the building’s planning status. With Eastbury Manor House about 1 mile west, it’s worth asking whether your own home is listed before planning a heat pump.

Why it’s worth doing now in Castle Green
Radiators that are too small for a heat pump’s lower flow temperature leave rooms cool. Checking and upsizing them as part of the installation avoids that. Approvals for flats in Castle Green can take longer than the install itself.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you are unsure, give us a ring on 07833 053749 or email us for straight advice and a fixed price.

Keeping the system healthy
Once we have finished, these simple steps help:
- Clear leaves and debris from the outdoor unit
- Look at insulation alongside the heat pump
- Use the settings explained at handover
Where we applied for a Boiler Upgrade Scheme grant, we keep you informed through the process, as the installer applies for it.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on, so keep it clear all year.

Common questions in Castle Green
Can I have air conditioning in a flat in Castle Green?
In many cases, yes, once the lease and the building’s rules are checked. 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.
Does the Boiler Upgrade Scheme cover homes in Castle Green?
Castle Green is in England, where the Boiler Upgrade Scheme runs. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Do you offer emergency call-outs?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we’ll talk you through the next steps.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do you cover Castle Green?
Yes. Our engineers work in Castle Green, as part of our area across London and the South East. Our base is in East Grinstead, West Sussex.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Castle Green and across Greater London. Let us know who the records should go to.
What affects the cost of air source heat pumps
A fixed price needs a few facts first. We look at:
- How many units are involved
- The brand, model and parts involved
- The electrical supply and whether a new circuit is needed
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered and we’ll price it together.
What to send for a quote
Good pictures often save a visit. Try to include:
- The fuse board and where it is in the property
- The outdoor side of the property, including any roof or flat area
- The make and model of the system, from the label
Getting a quote is straightforward. Send a few details and pictures, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
How the visit works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. So on the day, you don’t need a separate electrician for the electrical side. The work takes a few days for most air-to-water installations, with air-to-air systems often quicker. Let us know who controls access to the building in Castle Green, as that saves time on the day.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Installation, commissioning and MCS registration complete the job.
Getting ready for the visit
- Find the manual or the paperwork for the system, if you have it
- Arrange for someone to be there to let us in
- Let us know where the consumer unit is
Getting a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.
