Air source heat pumps in Great Offley, done properly
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems don’t heat hot water, so you will need another way to do that. If the problem is moving away from fossil-fuel heating and checking whether planning permission is needed, we can sort it out.
If your home in or near Great Offley is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Heat pumps in Great Offley: local notes
About 72% of households live in detached or semi-detached houses, according to the 2021 Census. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. Great Offley’s centre falls inside the Great Offley Conservation Area. Historic England lists about 22 buildings and structures within half a mile of the centre of Great Offley, including Church of St Mary Magdalene (c of E) (grade I). That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with the local planning authority (usually North Hertfordshire council).
Older homes near Church of St Mary Magdalene may need extra checks for planning and heat loss before a heat pump is designed. Every heat pump design starts with a room-by-room heat loss calculation.

Great Offley questions
Is the heat pump grant available in Great Offley?
Great Offley is in England, where the Boiler Upgrade Scheme runs. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. The installer applies, and we’re MCS certified.
Is Great Offley within the area you cover?
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 you come out in an emergency?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll agree what happens next.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
When will I hear back?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
What does an air-to-water heat pump cost?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. Your price depends on the survey, the emitters and the hot water and the quote is fixed.

Let and managed properties
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We’re happy to deal with either side, and the paperwork can go to both.
Before you call an engineer
There are a few things you can safely do yourself: 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.
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.
