Air source heat pumps for homes and businesses in Langley Bottom
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems don’t heat hot water, so you’ll need another way to do that. The work covers underfloor heating, radiator systems and hot water cylinders, and the jobs we see most are no space for a hot water cylinder and wanting to stop using oil, LPG or gas for heating.
Space for an outdoor unit is rarely an issue near Langley Bottom, so the design comes down to heat loss, radiators and hot water.
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. For any other brand, we explain the manufacturer’s terms on your quote.

Langley Bottom: your questions answered
Can I get the Boiler Upgrade Scheme grant in Langley Bottom?
Yes, if the home and the heat pump meet the scheme’s rules: Langley Bottom is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
Do you cover smaller places like Langley Bottom?
Yes. Langley Bottom is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Can I do any of the installation myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Which type of heat pump is right for my home?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
Is a heat pump permitted development?
Many installations on houses in England fall under permitted development, subject to the rules. Listed buildings and their curtilages are excluded, and listed building consent is a separate matter. We check what applies to you.
How much time does a heat pump install need?
The work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The survey lets us set a firm programme, and you can phone 07833 053749 or use the quote form to book it.
What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Photos of the existing unit help with repairs and servicing in Langley Bottom.

What the work involves, system by system
Outdoor unit position and planning
Flats and blocks of flats have different limits, and Article 4 directions can remove rights. Listed buildings also need separate consent and we check what applies to you.
Air-to-water heat pumps
Air-to-water systems take heat from the air and put it into your central heating and hot water. It replaces the boiler as the main heat source and we install it to MCS standards.

Homes in Langley Bottom and heat pumps
About 40% of households live in terraced houses, according to the 2021 Census. In a terrace, the outdoor unit position and the MCS noise check need particular care. On the National Heritage List, around 8 entries fall within 0.5 miles of the middle of Langley Bottom; Dyes Farmhouse (grade II*) is one. 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 (usually North Hertfordshire council).
With Knebworth House about 1.8 miles south-east, it’s worth asking whether your own home is listed before planning a heat pump. Every heat pump design starts with a room-by-room heat loss calculation.
