What air conditioning won’t do
Not every problem is solved by air source heat pumps, and we will tell you before we start. It does not solve:
- A grant for a home that doesn’t meet the scheme rules
- Improving the building’s insulation
- Tax rulings, which only HMRC can give

Air source heat pumps for homes and businesses in Adeyfield
Many air source heat pumps can be installed as permitted development in England, without a planning application. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We look at the planning position for your home during the survey. The work covers hot water cylinders, air-to-water heat pumps and radiator systems, and people most often call us about questions about listed buildings or conservation areas and finding a place for the outdoor unit.
Older homes around Adeyfield can be draughty or have solid walls, which a heat loss calculation will show. Sometimes insulating first makes more sense.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

Heat pumps in Adeyfield: local notes
About 48% of homes across Adeyfield and its surrounding area date from 1945 to 1972, according to VOA council tax data. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. On the National Heritage List, around 5 entries fall within 0.5 miles of the middle of Adeyfield; Crab Tree Inn (grade II) is one. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
Live in one of the older houses around St Barnabas? Expect the survey to look closely at heat loss and at the building’s planning status. If your home is listed, like Batchwood Hall about 4.2 miles east, listed building consent comes before any heat pump work.
Adeyfield is about 1 mile north-east of Hemel Hempstead, in Hertfordshire. Across the HP2 area, our engineers can take on air source heat pumps. Adeyfield is one of 381 towns, villages and districts in Hertfordshire where we work for homes and businesses. London is in our area too, around 23 miles away.
Jobs in HP2 and HP3 are looked at, quoted and booked the same way as anywhere else. Being close to the A414, Adeyfield is easy for our engineers to reach.

What the work involves, system by system
Heat loss surveys
Without a proper survey, a heat pump can be too big or too small, and both cause problems.
Radiators and underfloor heating
Underfloor heating works well with heat pumps because it uses lower temperatures and we look at it during the survey.
Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Book a yearly service
- Let the heat pump run steadily, as set up at handover
- Keep the outdoor unit clear all year
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork for future reference.
Keep radiators and indoor units unobstructed, as the system relies on them giving out heat.
Adeyfield questions
Will you come out to Adeyfield?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.
Is the heat pump grant available in Adeyfield?
Yes, the scheme covers homes in England, including Adeyfield, if they qualify. 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. We hold MCS certification, so the application is ours to make for you.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: a look first, a fixed-price quote and written records.
What does an air-to-water heat pump cost?
Air-to-water systems are £8,000–£16,000 (0% VAT on homes), before any grant. Your price depends on the survey, the emitters and the hot water and the quote is fixed.
Can I do any of the installation myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Is there a survey before the work?
Yes. For simple jobs, photos and a few details can be enough, while bigger systems and repairs that need testing get a visit.
What happens on the day
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work 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. Tell us about any gates or steps at your property near Adeyfield when you book.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Mention any roof access, ladders or high-level work
- Make sure we can reach the outdoor unit, or where it will go
How to get a quote
Quotes don’t take long. Call or email with a few details and we’ll come back to you the same working day. Where a survey is needed, we arrange a time that suits you.
