What we do, step by step
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Seeing the property in pictures first means the trip to Little Amwell can be planned properly.
- It starts with a conversation about the home, the existing heating and your plans.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
How to prepare
- Dig out any previous service or F-Gas records
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Tell us about any building rules, permits or sign-in
Getting a quote
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Air source heat pumps for homes and businesses in Little Amwell
As an MCS certified installer, we fit air source heat pumps for homes in Little Amwell and the rest of Hertfordshire. 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 help you work out which suits your home. If the problem is deciding on the outdoor unit position and working out whether radiators need upsizing, we can sort it out.
For a home around Little Amwell 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.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Your questions about air source heat pumps in Little Amwell
Can I get the Boiler Upgrade Scheme grant in Little Amwell?
Yes, if the home and the heat pump meet the scheme’s rules: Little Amwell is in England, where it applies. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. We hold MCS certification, so the application is ours to make for you.
Can I fit a heat pump in Little Amwell without planning permission?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Little Amwell holds about 30 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 needed, we check with East Hertfordshire council, which is normally the planning authority for Little Amwell.
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 you survey before quoting?
Yes. Every job is looked at first, either on a site survey or from pictures and details for simple jobs. A fixed-price quote follows.
How long does a heat pump installation take?
As a guide, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. The programme is planned to keep time without heating short and agreed before any work starts.
Do I need new radiators for a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs, so the quote covers any changes.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are members of Checkatrade too.

Aftercare tips
Looking after the system is mostly common sense. A few tips:
- Book a yearly service
- Check what your manufacturer’s warranty asks of you
- Find out the grant position at the survey
Should you have questions after the install, call us on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll talk it through. Annual servicing helps keep the system working well.
Let the heat pump run steadily rather than switching it on and off as explained at handover.
For landlords and property managers
For anyone managing more than one building, we can plan visits across the portfolio and price them together. Each property gets its own records, so each one has its own history.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
When something else is needed
A few issues sit outside what this work can do:
- Planning approval where permitted development does not apply
- Any gas work on the existing boiler
- A grant for a home that does not meet the scheme rules
If you’re not sure, just phone 07833 053749 or email us and we’ll give you a straight answer before booking.
