About our air source heat pumps in Stonymarsh
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Guesswork leads to systems that are too big or too small. Typical jobs include checking emitters for a heat pump and planning and permitted development questions, across underfloor heating, air-to-air heat pumps and air-to-water heat pumps.
In a place like Stonymarsh, some homes are listed, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Owner checks or an engineer?
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Do you need air source heat pumps in Stonymarsh?
When a home is being extended or renovated, it’s a good moment to look at heat pumps. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
These are the situations we see most often:
- Not knowing whether a grant applies
- Checking whether planning permission is needed
- Choosing between air-to-water and air-to-air
If your home is one of the older properties near Church of St Andrew, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

The process
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, which takes a few days on site, depending on the cylinder, the radiators and the pipework involved. A few photos help us make the most of a visit to Stonymarsh.
- First we talk through the property and the current system.
- We measure heat loss for every room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Keep pets and children away from the work area
- Dig out any previous service or F-Gas records

Stonymarsh: your questions answered
Can I fit a heat pump in Stonymarsh without planning permission?
That depends on the building and where the outdoor unit goes. Historic England lists about 4 buildings and structures within half a mile of the centre of Stonymarsh. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Test Valley council, which is normally the planning authority for Stonymarsh first.
Does the Boiler Upgrade Scheme cover homes in Stonymarsh?
Yes, the scheme covers homes in England, including Stonymarsh, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
How long will it take to install a heat pump?
It takes a few days for most air-to-water installations, with air-to-air systems often quicker. The cylinder, the radiators and the pipework make the biggest difference and the timing is set out with your quote.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone, and we are happy to show ours.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
