How we handle air source heat pumps in Bishop's Stortford
We install air source heat pumps in Bishop's Stortford and across Hertfordshire, and we’re MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We will explain which type fits your home and why. We’re often asked to deal with checking emitters for a heat pump and not knowing whether a grant applies, across homes heated by oil, LPG or gas, air-to-air heat pumps and radiator systems.
In a town like Bishop's Stortford, most heat pump enquiries are for houses heated by a gas boiler. We survey the heat loss, radiators, hot water and the outdoor unit position, then design and quote.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

How the job changes from property to property
Heat loss surveys
Without a proper survey, a heat pump can be too big or too small, and both cause problems.
The Boiler Upgrade Scheme
There’s one grant per property, and you can’t get a grant to replace a low-carbon system, and hybrid systems are not eligible.
What affects the quote in Bishop's Stortford
Your quote is based on your property. We consider:
- What kind of system it is
- Whether the existing supply is suitable
- How many units are involved
Height, access and the distance between the indoor and outdoor units all affect the cost. We take each of them into account, and the price is fixed before we start.
What to send for a quote
What to send for a quote:
- A photo of the consumer unit with the cover closed
- Any error code or flashing light on the display
- Photos showing the indoor unit and the space around it
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.
What a heat pump looks like in Bishop's Stortford
Bishop's Stortford is about 28 miles from central London, well within the area we cover from our base in East Grinstead. Central Bishop's Stortford is inside the Bishop's Stortford Conservation Area. On the National Heritage List, around 76 entries fall within 0.5 miles of the middle of Bishop's Stortford; Church of St Michael (grade I) is one. For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the planning team at East Hertfordshire council, which usually handles Bishop's Stortford where necessary.
Older homes near Church of St Michael may need extra checks for planning and heat loss before a heat pump is designed. Homeowners near Bishops Stortford station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.

Owner checks or an engineer?
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and ring us on 07833 053749, or email if that’s easier.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
What happens on the day
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, 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. The more we can see first, the quicker the visit to Bishop's Stortford.
- It starts with a conversation about the home, the existing heating and your plans.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Keep pets out of the rooms we are working in
- Make sure we can reach the consumer unit or fuse board

Common questions in Bishop's Stortford
Is Bishop's Stortford in your area for air source heat pumps?
Yes. Bishop's Stortford is one of the places we cover. Just phone 07833 053749 or fill in the contact form with a few details.
Does the Boiler Upgrade Scheme cover homes in Bishop's Stortford?
Bishop's Stortford is covered, as the scheme runs across England and Wales. 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. We hold MCS certification, so the application is ours to make for you.
Does servicing affect my 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. Keep every service record either way.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do you look at the job first?
Yes. We always look before we price, either on a site survey or from pictures and details for simple jobs. Then you get a fixed-price quote.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
What’s the price of a heat pump installation?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
