Hexton questions
Do you cover smaller places like Hexton?
We do. Villages and hamlets get the same service as the bigger towns. A few photos and the postcode are enough to get things started.
Can I fit a heat pump in Hexton without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Hexton sits inside the Hexton Conservation Area. 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 local planning authority (for Hexton, typically North Hertfordshire council).
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Do you work on all makes?
We install and work on the leading makes, 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.
Do I get paperwork after the visit?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
What VAT do I pay on a heat pump?
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5%. It does not apply to businesses. This is general information, not tax advice.
Air source heat pumps in Hexton
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. This is general information, not tax advice. The work covers air-to-water heat pumps, homes heated by oil, LPG or gas and hot water cylinders, and the jobs we see most are finding a place for the outdoor unit and a boiler that’s getting old.
For a home around Hexton that’s 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: 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.

Different systems, different jobs
VAT on heat pumps
Heat pumps in homes carry 0% VAT until 31 March 2027, and 5% after that following HMRC’s rules on energy-saving materials. Businesses pay the standard rate.
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, which is why radiator sizing is part of the survey.
Before you call an engineer
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
What a heat pump looks like in Hexton
Census 2021 figures found about 77% of households in detached or semi-detached houses. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Period properties close to Church of St Faith (Church of England) can suit a heat pump, though insulation and any heritage protection are checked first. Harlington Manor, roughly 4.3 miles west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Leave it or put it right?
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water heats radiators and hot water, and can attract a £7,500 grant where eligible; air-to-air heats and cools rooms, and only qualifies for £2,500 under strict conditions, and we explain which fits your home. An early booking makes the visit to Hexton easier to arrange.
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we will go through it with you.

The process
On the day, we arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, 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. Photos of the room and the outside of the property help us plan a visit to Hexton.
- We start with your plans and the property.
- 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.
- Installation follows on the agreed dates.
- 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
- Let us know where we can park and unload
- Let us know if the units are on a roof, a high wall or in a locked area
