About our air source heat pumps in Test Valley
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. That follows HMRC Notice 708/6, and it does not 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. If the problem is radiators that may be too small for a heat pump and choosing between air-to-water and air-to-air, we can sort it out.
Space for an outdoor unit is rarely an issue near Test Valley, so the design comes down to heat loss, radiators and hot water.
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 and it’s worth keeping safe.

What we do, step by step
We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. 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 Test Valley around you.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Move furniture away from the wall where we will be working
- Find the manual or the paperwork for the system, if you have it
- Make sure someone can let us in at the agreed time
Ask for a quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Looking after your system
Looking after it is simple, and it makes the next visit easier:
- Clear leaves and debris from the outdoor unit
- Look at insulation alongside the heat pump
- Check eligibility for the Boiler Upgrade Scheme early
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes, and that’s normal.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.

FAQs for Test Valley
Is the heat pump grant available in Test Valley?
Test Valley is in England, where the Boiler Upgrade Scheme runs. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. You don’t apply yourself: the MCS certified installer does, which is us.
Do you cover Test Valley for air source heat pumps?
Yes. We work across London and the South East from our base in East Grinstead, and Test Valley is part of that. Get in touch with the details and we reply the same working day.
Do I get paperwork after the visit?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
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.
Do you work on all makes?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
When to call us in Test Valley
Some people want to move away from burning fossil fuels at home. With a heat pump, the heat comes from the air outside and the system runs on electricity, which is why it fits that aim.
Customers typically contact us after spotting one of these:
- Planning and permitted development questions
- Not knowing whether a grant applies
- A boiler that’s getting old
Stargroves lies about 2.7 miles north. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
Questions to ask before you book
- Which VAT rate the quote uses, and why
- Whether anyone has checked the property or the system first
- What happens if the job turns out to be different on the day
What air conditioning will not do
Air source heat pumps can’t fix everything, and we will tell you before any work starts. It does not solve:
- Tax rulings, which only HMRC can give
- Planning approval where permitted development does not apply
- Disconnecting or servicing a gas boiler
If you’re not sure, just ring us on 07833 053749 or drop us a line and we’ll give you a straight answer before you book.
