Mott's Mill questions
Can I get the Boiler Upgrade Scheme grant in Mott's Mill?
Yes, the scheme covers homes in England, including Mott's Mill, if they qualify. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. The installer applies, and we are MCS certified.
Do I need planning permission for a heat pump in Mott's Mill?
That depends on the building and where the outdoor unit goes. Around 9 listed entries sit within 0.5 miles of central Mott's Mill. 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 Wealden council, which is usually the planning authority for Mott's Mill.
How soon will you get back to me?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before we start, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. We install both types.
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.
Air source heat pumps in Mott's Mill, done properly
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit cannot be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. We are often asked to deal with moving away from fossil-fuel heating and questions about listed buildings or conservation areas, on radiator systems, air-to-water heat pumps and underfloor heating.
Homes around Mott's Mill usually have room outside for a heat pump, 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.

Air source heat pumps in Mott's Mill: the local picture
About 48% of homes in Mott's Mill and the neighbourhoods around it were built before 1919, according to VOA council tax data, and the 2021 Census found about 83% of households in detached or semi-detached houses. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Historic houses such as Groombridge Place, about 1.6 miles north-east, are a reminder that listed homes need consent before a heat pump goes in. If your home is one of the older properties near Church of St Thomas the Apostle, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

Owner checks or an engineer?
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
For landlords and property managers
If you look after several properties, we can quote and plan the work across all of them. Each property gets its own records, so each one has its own history.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork, and we will keep everyone informed.
