Air source heat pumps in Bendish
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. With air-to-air, hot water has to come from something else. The work covers underfloor heating, air-to-water heat pumps and hot water cylinders, and people most often call us about moving away from fossil-fuel heating and checking eligibility for a heat pump grant.
If your home in or near Bendish 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.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Questions from Bendish
Will you come out to Bendish?
Yes. Bendish is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Does the Boiler Upgrade Scheme cover homes in Bendish?
Yes, if the home and the heat pump meet the scheme’s rules: Bendish is in England, where it applies. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. You do not apply yourself: the MCS certified installer does, which is us.
Do you look at the job first?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
How much does an air source heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder, and air-to-air systems are priced after a survey.
Can you look at a system you didn’t fit?
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.
How soon will you get back to me?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Do I need to service the system to keep 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. Either way, keep a record of every service.
When it’s something else
To be straight with you, there are a few things this work will not fix:
- A grant for a home that does not meet the scheme rules
- Draught-proofing and insulation upgrades
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
If in doubt, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk and we will say what we think.

Homes in Bendish and heat pumps
The 2021 Census found about 72% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. The middle of Bendish is part of the Bendish Conservation Area. About 7 listed entries lie within half a mile of central Bendish, The Harrow Public House (grade II) among them. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the local planning authority (typically North Hertfordshire council).
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler. Shaw's Corner lies about 3.7 miles south-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
Bendish is about 5 miles north of Harpenden, in Hertfordshire. Whatever kind of property you have in Bendish, our engineers can help with air source heat pumps.

Aftercare tips
Once we have finished, these simple steps help:
- Use the settings explained at handover
- Keep up with insulation and draught-proofing
- Keep the MCS certificate with the manufacturer’s paperwork
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. You might see steam or hear the unit change note, and that’s normal.
Keep insulation and draught-proofing in good order, as lower heat loss means the system has less to do.
Before you call an engineer
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.
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.
What happens on the day
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. Anything unexpected is raised with you before we go further. After that, 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. For a place like Bendish, the timing is set with you and the travel is our side of the planning.
