Air source heat pumps in Newgate Street
Air-to-water heat pumps heat your hot water through 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. We are often asked to deal with working out whether radiators need upsizing and checking eligibility for a heat pump grant, across radiator systems, air-to-air heat pumps and hot water cylinders.
For a home around Newgate Street that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
We are 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.

Questions from Newgate Street
Is a heat pump in Newgate Street permitted development?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Newgate Street holds about 7 listed buildings and structures. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Newgate Street, typically Welwyn Hatfield council).
Does the Boiler Upgrade Scheme cover homes in Newgate Street?
Newgate Street is in England, where the Boiler Upgrade Scheme runs. 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. You don’t apply yourself: the MCS certified installer does, which is us.
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. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Is Newgate Street in your area?
Yes. We work in Newgate Street and the rest of Hertfordshire, within the London and South East area we cover. For a fixed-price quote, ring us on 07833 053749 or email us.
Do you offer emergency call-outs?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
How soon will you get back to me?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
How it works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. Somewhere like Newgate Street, it helps to know about lanes, gates and where to park.
- We talk through your home, your current heating and what you want from a heat pump.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Let us know if the units are on a roof, a high wall or in a locked area
- Let us know if the building has a permit or sign-in process
- Make sure we can reach the consumer unit or fuse board

Related advice
What you can do yourself, and what needs us
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 phone 07833 053749 or write to us at info@aircondoctor.co.uk.
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. Ask us to quote for a move instead.
Homes in Newgate Street and heat pumps
About 44% of homes in and around Newgate Street date from 1945 to 1972, according to Valuation Office Agency council tax records, and Census 2021 figures found about 84% of households in detached or semi-detached houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Houses usually have space for an outdoor unit and a hot water cylinder.
Live in one of the older houses around Church of St Mary Ponsbourne? Expect the survey to look closely at heat loss and at the building’s planning status. Wyllyotts Manor, roughly 4 miles south-west, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.
