Air source heat pumps in High Cross, done properly
We install air source heat pumps in High Cross and across Hertfordshire, and we’re MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We will explain which type fits your home and why. If the problem is wanting to stop using oil, LPG or gas for heating and deciding which kind of heat pump suits the home, we can help.
Space for an outdoor unit is rarely an issue near High Cross, so the design comes down to heat loss, radiators and hot water.
The records are your 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.

High Cross: your questions answered
Will a heat pump in High Cross need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of High Cross holds about 21 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 can’t face a road. Where necessary, we check with the local planning authority (for High Cross, normally East Hertfordshire council).
Can I get the Boiler Upgrade Scheme grant in High Cross?
High Cross is covered, as the scheme runs across England and Wales. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. As an MCS certified installer, we apply for it on your behalf.
Will I get records for the system?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Do you work in High Cross?
Yes. High Cross is part of the area we cover, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.
Does servicing affect my warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.
Do I need new radiators for a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Do you look at the job first?
Yes. For simple jobs, photos and a few details can be enough, while bigger systems and repairs that need testing get a visit.
When it’s something else
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- Getting planning permission or listed building consent on your behalf
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Improving the building’s insulation
Not sure which it is? You can call us on 07833 053749 or fill in the contact form and we’ll tell you honestly.

What a heat pump looks like in High Cross
About 47% of homes across High Cross and its surrounding area date from 1945 to 1972, according to Valuation Office Agency council tax records. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks.
Live in one of the older houses around Church of St John the Evangelist? Expect the survey to look closely at heat loss and at the building’s planning status. Much Hadham Palace, roughly 4.2 miles east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Safe owner checks
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
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. Anything inside the units, the electrics and the refrigerant is engineer’s work.
What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, and that takes a few days for most air-to-water installations, with air-to-air systems often quicker. A few photos help us make the most of a visit to High Cross.
- First we find out about the property, the heating you have now and what you are hoping for.
- 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.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Clear the space around the indoor unit, or where it will go
- Name a contact who can meet us at the agreed time
