Air source heat pumps in Great Thorness, done properly
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 doesn’t apply to businesses, and 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 questions about where the outdoor unit can go and moving away from fossil-fuel heating, we can help.
For a home around Great Thorness that is off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Questions from Great Thorness
Do I need planning permission for a heat pump in Great Thorness?
It depends on the property. A conservation area takes in the middle of Great Thorness. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Isle of Wight council, usually the authority for Great Thorness.
Is the coast a problem for outdoor units in Great Thorness?
It can. Great Thorness is within about 1 mile of the coast, and salt air speeds up corrosion on outdoor units. 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.
Will skipping a service affect the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Am I eligible for a heat pump grant?
Not every home qualifies, so we check. Only one grant is available per property, it can’t replace a low-carbon system, and hybrids don’t qualify and other conditions apply.
How long will it take to install a heat pump?
An installation takes a few days for most air-to-water installations, with air-to-air systems often quicker. We confirm the timing after the survey, and you can call 07833 053749 or drop us a line to book it.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.

Let and managed properties
If you look after several properties, we can quote and plan the work across all of them. Every address has its own paperwork, so each one has its own history.
Portfolio owners often want one contractor and one number. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
When to call us in Great Thorness
People also ask about air-to-air heat pumps because they heat and cool. They warm rooms directly through indoor units and switch to cooling in warm weather. The grant only applies in some cases, so we check first.
Most people get in touch after spotting one of these:
- Radiators that may be too small for a heat pump
- Moving away from fossil-fuel heating
- Not knowing whether a grant applies
Historic houses such as Swainston Manor, about 3 miles south, are a reminder that listed homes need consent before a heat pump goes in.
What to look for in a quote
- What the manufacturer’s warranty covers and for how long
- Whether anyone has checked the property or the system first
- Whether the electrical work is done by a registered contractor, such as NICEIC approved

The process
You don’t need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. Before we leave, the area is tidied and we explain what we’ve done. Visits to Great Thorness are agreed with you in advance and planned so the job can be finished in one trip where possible.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Preparing for the visit
- Keep pets and children away from the work area
- Tell us about any building rules, permits or sign-in
- Unlock any gate, garage or side passage we need

Heat loss surveys
Getting the survey right avoids undersized or oversized systems and that matters for comfort and running.
Outdoor unit position and planning
The outdoor unit needs a position with good airflow, a solid base and a sensible pipe route. We also consider neighbours and noise, as MCS 020(a) includes a noise check.
