Air source heat pumps in Langley End: the local picture
Census 2021 figures found about 40% of households in terraced houses. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door.
Historic houses such as Knebworth House, about 2.7 miles south-east, are a reminder that listed homes need consent before a heat pump goes in.

How we handle air source heat pumps in Langley End
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb isn’t good enough. We’re often asked to deal with wanting to stop using oil, LPG or gas for heating and checking emitters for a heat pump, on homes heated by oil, LPG or gas, air-to-water heat pumps and radiator systems.
Homes around Langley End typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Your questions about air source heat pumps in Langley End
Do you cover smaller places like Langley End?
Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.
Is planning permission needed for a heat pump in Langley End?
It depends on the property. Historic England lists about 10 buildings and structures within half a mile of the centre of Langley End. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at North Hertfordshire council, normally the authority for Langley End.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
How much does an air source heat pump cost?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for example, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us in Langley End and across Hertfordshire. Tell us who should receive the paperwork.
Will my radiators work with a heat pump?
It varies from room to room. We check them all during the survey and the quote shows what’s needed.
What owners can safely do
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
How the visit works
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes a few days for most air-to-water installations, with air-to-air systems often quicker. Work in Langley End is booked in advance at a time that suits you.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- We install, commission and register the system under MCS.
How to prepare
- Mention any parking restrictions near the property
- Plan for pets to be kept clear during the visit
- Clear the space around the indoor unit, or where it will go

When to call us in Langley End
Homes with electric heating sometimes look at heat pumps as an alternative. A survey shows whether a heat pump suits the property and what would need to change, and we explain the grant position for your home.
Look out for these signs:
- An oil, LPG or gas boiler near the end of its life
- No space for a hot water cylinder
- Planning and permitted development questions
Older homes near All Saints Church may need extra checks for planning and heat loss before a heat pump is designed.
What your quote should include
- Whether testing, commissioning and paperwork are included
- Who does the electrical work, and whether they can certify it
- How extra work would be agreed if they find something unexpected
