Air source heat pumps in Molehill Green
Every installation starts with a heat loss survey. That tells us how much heat the home needs, room by room so the system is sized to match. Guesswork leads to systems that are too big or too small. The work covers homes heated by oil, LPG or gas, air-to-air heat pumps and air-to-water heat pumps, and common reasons people get in touch are checking emitters for a heat pump and finding a place for the outdoor unit.
Space for an outdoor unit is rarely an issue near Molehill Green, so the design comes down to heat loss, radiators and hot water.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

The process
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. 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, and we tidy up before we leave. Photos of the room and the outside of the property help us plan a visit to Molehill Green.
- We start with your plans and the property.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We explain which type of heat pump suits the home and whether a grant could apply.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
How to prepare
- Have the make and model of any existing unit to hand
- Clear a path to the units and the space around them
- Make sure we can reach the consumer unit or fuse board

Air source heat pumps around Molehill Green
About 47% of homes in Molehill Green and the neighbourhoods around it have been built since 2000, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 73% of households in detached or semi-detached houses. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. Houses usually have space for an outdoor unit and a hot water cylinder.
For a home near Stansted Airport station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.

What happens if it’s left?
The two types suit different homes and needs. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases, and we explain which fits your home. Small faults tend to grow, so it’s worth dealing with them early.
The cost depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. You get a fixed price before work begins, so there are no surprises.

Common questions in Molehill Green
Will a heat pump in Molehill Green need planning permission?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Molehill Green holds about 13 listed buildings and structures. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the local planning authority (for Molehill Green, normally Uttlesford council) first.
Is Molehill Green within the area you cover?
Yes. Molehill Green 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.
Does the grant cover air-to-air heat pumps?
The air-to-air grant is £2,500, and only some homes qualify. The system has to replace the fossil-fuel heating and heat the whole home, installed by an MCS certified installer.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is recorded and F-Gas records kept where they apply.
Do I need to service the system to keep the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Do you survey before quoting?
Yes. For simple jobs, photos and a few details can be enough, while larger systems and faults that need testing are seen on site.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling, and we help you choose. Both are part of what we install.
Common problems we fix in Molehill Green
Many enquiries start with a question about the Boiler Upgrade Scheme. Eligibility depends on the property, the system and the scheme rules and we confirm it before you go ahead.
Most people get in touch when they notice one of these:
- Deciding which kind of heat pump suits the home
- Working out where a cylinder could go
- Moving away from fossil-fuel heating
If your home is listed, like Horham Hall about 3.2 miles north-east, listed building consent comes before any heat pump work.
What your quote should include
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- How extra work would be agreed if they find something unexpected
- Whether the price is fixed or an estimate
What air conditioning won’t do
An honest diagnosis matters more to us than a booking, so here’s what air source heat pumps won’t do:
- Planning approval where permitted development does not apply
- Grants for hybrid systems or replacements of low-carbon systems
- Insulation work, such as loft or cavity wall insulation
If in doubt, ring 07833 053749, or email if that’s easier and we’ll say what we think.
