How the visit works
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the pictures you sent. If something is different, we talk it through with you before carrying on. From there, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. For a village like Underling Green, tell us about narrow lanes, gates and parking when you book.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Before we arrive
- Have the make and model of any existing unit to hand
- Unlock any gate, garage or side passage we need
- Mention any parking restrictions near the property

How we handle air source heat pumps in Underling Green
Hot water from an air-to-water system is stored in 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 will need another way to do that. The work covers hot water cylinders, air-to-air heat pumps and radiator systems, and people most often call us about plans to switch to electric heating with a heat pump and questions about where the outdoor unit can go.
If your home in or near Underling Green is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

What a heat pump looks like in Underling Green
VOA council tax data put about 36% of homes in and around Underling Green before 1919, and about 71% of households live in detached or semi-detached houses, according to the 2021 Census. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. Houses usually have space for an outdoor unit and a hot water cylinder.
A heat loss calculation decides the size of heat pump your home needs.

Landlords, agents and facilities managers
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we will keep everyone informed.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we are happy to deal with whoever it is.
What we’re called out for in Underling Green
An ageing boiler is often the moment people start thinking about a heat pump. Planning the change before the boiler fails gives you time to survey, design and apply for any grant instead of making a rushed decision when the heating stops.
Look out for any of the following:
- No space for a hot water cylinder
- Not knowing whether a grant applies
- Moving away from fossil-fuel heating
Historic houses such as Stoneacre, about 5 miles north-east, are a reminder that listed homes need consent before a heat pump goes in.

Underling Green: your questions answered
Will a heat pump in Underling Green need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Around 12 listed entries sit within 0.5 miles of central Underling Green. 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 Maidstone council, which is typically the planning authority for Underling Green first.
Does the Boiler Upgrade Scheme cover homes in Underling Green?
Yes, the scheme covers homes in England, including Underling Green, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. You do not apply yourself: the MCS certified installer does, which is us.
Do you work in Underling Green?
Yes. We work in Underling Green and across Kent, as part of our area across London and the South East. For a fixed-price quote, call us on 07833 053749 or fill in the contact form.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Can I do the refrigerant work myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
