Air source heat pumps in Charlton, done properly
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation and the installer makes the application. Eligibility depends on the property, so we confirm it before anything is agreed. The work covers hot water cylinders, air-to-air heat pumps and air-to-water heat pumps, and the jobs we see most are a boiler that’s getting old and working out where a cylinder could go.
Space for an outdoor unit is rarely an issue near Charlton, so the design focuses on heat loss and radiators.
The records are your system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Heat pumps in Charlton: local notes
Wren Cottage, listed at grade II, is one of roughly 9 protected buildings and structures in the half-mile around Charlton’s centre. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the local planning authority (typically Test Valley council). About 77% of households live in detached or semi-detached houses, according to the last census (2021). Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
For a home near Andover station, the survey looks at whether an air-to-water or air-to-air heat pump suits better. Period properties close to St Thomas can suit a heat pump, though insulation and any heritage protection are checked first.

How it works
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. We agree a date with you and plan the visit to Charlton so we arrive with what’s needed.
- First we find out about the property, the heating you have now and what you are hoping for.
- 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.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Commissioning, MCS certification and a handover of the controls finish the job.
How to prepare
- Make sure someone can let us in at the agreed time
- Let us know where the consumer unit is
- Find the manual or the paperwork for the system, if you have it

Your questions about air source heat pumps in Charlton
Does the Boiler Upgrade Scheme cover homes in Charlton?
Charlton is covered, as the scheme runs across England and Wales. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
Is Charlton within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. A few pictures and the postcode are enough to get things started.
Which type of heat pump is right for my home?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling. The survey helps decide. Both are part of what we install.
How much time does a heat pump install need?
Expect it to take several days for an air-to-water system with a new cylinder, less for an air-to-air system. The cylinder, the radiators and the pipework make the biggest difference and the timing is set out with your quote.
Is a heat pump permitted development?
Many installations on houses in England fall under permitted development, subject to the rules. Listed buildings and their curtilages are excluded, and listed building consent is a separate matter, so we check for your property.
Do I need new radiators for a heat pump?
We find out during the survey. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.
Do you provide F-Gas records?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Keeping the system healthy
So the system stays in good health:
- Find out the grant position at the survey
- Diary the next service
- Check what your manufacturer’s warranty asks of you
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. It may give off steam or sound different for a few minutes, and that is normal.
Heat pumps prefer steady, low-temperature running as explained at handover.
For landlords and property managers
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We can quote either party, and the paperwork can go to both.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed-price quote.
Why deal with it now?
Planning rules have specific conditions. Checking the position for your home at the survey stage avoids surprises later, including conservation areas, listed buildings and Article 4 directions. For a village like Charlton, booking ahead lets us plan the trip properly.
The price reflects the work, not guesswork. That’s why we look at the job first, from photos or on a survey, and why the quote is fixed before work begins.
