Owner checks or an engineer?
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
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. If you suspect a leak, switch the system off and call us.
How we handle air source heat pumps in Mongewell
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems don’t heat hot water, so you’ll need another way to do that. If the problem is plans to switch to electric heating with a heat pump and working out whether radiators need upsizing, we can help.
Space for an outdoor unit is rarely an issue near Mongewell, so the design focuses on heat loss and radiators.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Mongewell questions
Does the Boiler Upgrade Scheme cover homes in Mongewell?
Yes, if the home and the heat pump meet the scheme’s rules: Mongewell is in England, where it applies. 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.
Do I need planning permission for a heat pump in Mongewell?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Mongewell holds about 18 listed buildings and structures. 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 don’t 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 South Oxfordshire council, which is typically the planning authority for Mongewell.
Do I need new radiators for a heat pump?
We find out during the survey. Where a radiator is already large enough, it stays and any changes are in the quote.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Does servicing affect my 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 protect the property while you work?
Protection goes down first: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
What happens on the day
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Visits to Mongewell are agreed with you in advance and planned so the job can be finished in one trip where possible.
- First we talk through the property and the current system.
- We measure heat loss for every 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.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear access to the fuse board
- Move furniture away from the wall where we will be working
How to get a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.

Do you need air source heat pumps in Mongewell?
Many people look at heat pumps when an oil, LPG or gas boiler is getting old. Starting early leaves time for the survey, the design and any grant application instead of making a rushed decision when the heating stops.
The things we are asked about most include:
- Checking whether planning permission is needed
- Questions about the Boiler Upgrade Scheme
- Moving away from fossil-fuel heating
Live in one of the older houses around St Mary's Church? Expect the survey to look closely at heat loss and at the building’s planning status.
