About our air source heat pumps in Marchwood
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 does not apply to businesses. For air-to-air systems, we confirm the VAT on your quote. This is general information, not tax advice. The work covers air-to-air heat pumps, hot water cylinders and underfloor heating, and the jobs we see most are moving away from fossil-fuel heating and not knowing whether a grant applies.
For a house near Marchwood, space outside is rarely the problem, so heat loss, radiators and the electrics are what we check.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

How it works
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes, and we clear up before we go. We plan the visit to Marchwood from the survey or your pictures.
- 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.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Preparing for the visit
- Let us know if the building has a permit or sign-in process
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Clear a path to the units and the space around them
Getting a price
Getting a quote is straightforward. Call or email with a few details and we’ll come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.

What owners can safely do
On air conditioning, the filters in the indoor unit are normally the one part owners can clean, 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.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Homes in Marchwood and heat pumps
The coast is only about 1 mile from Marchwood. Salt air is hard on outdoor units, so a heat pump near the sea needs a sensible position and regular checks, and some models offer corrosion protection for coastal sites. Listed buildings are part of the picture here: about 6 within half a mile of the centre, such as Malthouse Farmhouse (grade II). For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the local planning authority (normally New Forest council) where needed.
Southampton Tudor House and Garden, roughly 2 miles east, is a reminder to check your home’s listing status: permitted development does not cover listed buildings. If your home is one of the older properties near Church of St John the Apostle, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

After we have gone
Every system needs looking after, and most of it is easy. Our tips:
- Use the settings explained at handover
- Keep the outdoor unit clear all year
- Read the manufacturer’s warranty terms for your brand
Should you have questions after the install, call us on 07833 053749 or drop us a line and we will look into it. A yearly service is a good habit.
Don’t cover radiators with furniture or heavy curtains so the heat can get into the room.
Why deal with it now?
Permitted development rules can change, and conditions vary between properties. Checking the position for your home at the survey stage avoids surprises later, including conservation areas, listed buildings and Article 4 directions. A system that’s left with a fault, or without a service, typically costs more to run.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are unsure, phone 07833 053749 for straight advice and a fixed price.

Your questions about air source heat pumps in Marchwood
Does sea air affect air conditioning in Marchwood?
It can, as Marchwood is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Do you cover smaller places like Marchwood?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Does servicing affect my warranty?
It can, for some brands. Send us the make and model and we’ll tell you what the manufacturer expects, and book the service at the interval they recommend.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How do you keep the place clean during the work?
Protection goes down first: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Do I need new radiators for a heat pump?
It varies from room to room. The survey compares each radiator with the room’s needs and the quote shows what’s needed.
