How we handle air source heat pumps in Hamsey
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. Please treat this as general information rather than tax advice. Common call-outs are for checking emitters for a heat pump and comparing heat pump types, across air-to-air heat pumps, underfloor heating and homes heated by oil, LPG or gas.
Older and listed homes in villages like Hamsey need extra care, and permitted development doesn’t cover listed buildings, so consent comes first.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Common questions in Hamsey
Is Hamsey within the area you cover?
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.
Will a heat pump in Hamsey need planning permission?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Hamsey holds about 6 listed buildings and structures. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where necessary, we check with the local planning authority (for Hamsey, typically Lewes council).
Should I choose air-to-water or air-to-air?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water, and we explain which suits your home.
What’s the price of a heat pump installation?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder, and air-to-air systems are priced after a survey.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Can I get a grant for an air-to-air heat pump?
Yes, but only where it becomes the home’s main heating. An air-to-air heat pump can get £2,500 if it replaces the fossil-fuel heating, meets the full heating demand, is fitted by an MCS certified installer and is in a home. Fitted alongside a boiler, it will not qualify.
Why act early in Hamsey
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Surveying and designing in advance means the system is sized right and any grant is applied for while the old heating still works. An early booking makes the visit to Hamsey easier to arrange.
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered, and you will get one fixed price.

Heat pumps in Hamsey: local notes
The last census (2021) found about 37% of households in terraced houses. In a terrace, the outdoor unit position and the MCS noise check need particular care.
If your home is listed, like Anne of Cleves House about 1.9 miles south, listed building consent comes before any heat pump work. Homeowners near Cooksbridge station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.

What we do, step by step
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. The work on site takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we clear up before we go. For a place like Hamsey, the timing is set with you and the travel is our side of the planning.
- First, a chat about the property and your goals for the heating.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Move furniture away from the wall where we will be working
- Name a contact who can meet us at the agreed time
- Make sure we can reach the outdoor unit, or where it will go
