About our air source heat pumps in Walton on the Hill
Every installation starts with a heat loss survey. That tells us how much heat the home needs, room by room, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb isn’t good enough. The work covers radiator systems, homes heated by oil, LPG or gas and air-to-air heat pumps, and common reasons people get in touch are radiators that may be too small for a heat pump and wanting to stop using oil, LPG or gas for heating.
Homes around Walton on the Hill usually have room outside for a heat pump, so the design focuses on heat loss and radiators.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Aftercare tips
Simple habits make a real difference. We recommend:
- Keep radiators clear
- Keep up with insulation and draught-proofing
- Check eligibility for the Boiler Upgrade Scheme early
We show you how to use the controls and explain how a heat pump works differently from a boiler. Steady running suits a heat pump better than switching on and off, and we will explain the settings for your home.
Have the system serviced regularly. Check the manufacturer’s terms, as they may include servicing conditions.

In England and Wales, the Boiler Upgrade Scheme offers grants towards heat pumps: £7,500 for air-to-water and ground source, and £2,500 for air-to-air in limited cases. The installer applies.
Why deal with it now?
If the emitters cannot give out enough heat, some rooms will not get warm enough. Checking and upsizing them as part of the installation avoids that. Planning ahead for a job in Walton on the Hill means we can bring everything needed.
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered, and you’ll get one fixed price.

Walton on the Hill: your questions answered
Is the heat pump grant available in Walton on the Hill?
Walton on the Hill is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. The installer applies, and we are MCS certified.
Will you come out to Walton on the Hill?
We do. Villages and hamlets get the same service as the bigger towns. A few pictures and the postcode are enough to get things started.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Are my radiators big enough for a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Will I need planning consent for an air source heat pump?
Under the Planning Portal rules, a heat pump on a house can often be permitted development. Listed buildings are excluded, and listed building consent is separate. We check what applies to you.
How much time does a heat pump install need?
A typical installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The programme is planned to keep time without heating short, and we explain it in advance.
When will I hear back?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
