About our air source heat pumps in Hunsdon
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 working out whether radiators need upsizing and finding a place for the outdoor unit, we can sort it out.
Homes around Hunsdon usually have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Your questions about air source heat pumps in Hunsdon
Can I get the Boiler Upgrade Scheme grant in Hunsdon?
Hunsdon is covered, as the scheme runs across England and Wales. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You don’t apply yourself: the MCS certified installer does, which is us.
Do I need planning permission for a heat pump in Hunsdon?
It depends on the property. The Hunsdon Conservation Area takes in the middle of Hunsdon. 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 East Hertfordshire council, usually the authority for Hunsdon.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Keep every service record either way.
How much time does a heat pump install need?
The work takes a few days for most air-to-water installations, with air-to-air systems often quicker. The survey lets us set a firm programme, and you can phone us on 07833 053749 to book it.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Should I choose air-to-water or air-to-air?
It depends on your home, your heating and whether you want cooling. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions, and we set out the options after the survey.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll agree what happens next.
Honest limits
Air source heat pumps can’t fix everything, and we’d rather say so up front. It does not solve:
- Insulation work, such as loft or cavity wall insulation
- Tax advice on your own circumstances
- Planning approval where permitted development doesn’t apply
Not sure which it is? You can call 07833 053749 or drop us a line and we’ll tell you honestly before you book.

What a heat pump looks like in Hunsdon
Census 2021 figures found about 74% of households in detached or semi-detached houses. Houses usually have space for an outdoor unit and a hot water cylinder.
Live in one of the older houses around St Francis Chapel? Expect the survey to look closely at heat loss and at the building’s planning status. If your home is listed, like Much Hadham Palace about 3.6 miles north, listed building consent comes before any heat pump work.

Other services in Hunsdon
Owner checks or an engineer?
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. 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.
What happens on the day
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, which 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. Rural lanes and tight entrances are worth mentioning before a visit to Hunsdon.

Advice
After we have gone
Every system needs looking after, and most of it is easy. Our tips:
- Check eligibility for the Boiler Upgrade Scheme early
- Avoid switching the heat pump on and off often
- Know the servicing conditions in your warranty
Equipment warranties come from the manufacturer. We explain the terms for your brand, including any servicing conditions.
Heat pumps prefer steady, low-temperature running as explained at handover.
