Air source heat pumps in Mark Cross
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We look at the planning position for your home during the survey. The work covers air-to-air heat pumps, radiator systems and air-to-water heat pumps, and people most often call us about finding a place for the outdoor unit and ageing boilers that will need replacing.
In a place like Mark Cross, some homes are listed, and permitted development does not cover listed buildings, so consent comes first.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

The process
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. For a place like Mark Cross, the timing is set with you and the travel is our side of the planning.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- You get a fixed price, with any grant and the VAT set out.
- Installation, commissioning and MCS registration complete the job.
Before we arrive
- Clear the space around the indoor unit, or where it will go
- Let us know if the building has a permit or sign-in process
- Let us know if the units are on a roof, a high wall or in a locked area
Ask for a quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
Advice
What we are called out for in Mark Cross
A common reason is wanting to stop burning gas, oil or LPG. With a heat pump, the heat comes from the air outside and the system runs on electricity, which is why it fits that aim.
Common reasons people call us are:
- Wanting to stop using oil, LPG or gas for heating
- Deciding which kind of heat pump suits the home
- Radiators that may be too small for a heat pump
Period properties close to St Marks can suit a heat pump, though insulation and any heritage protection are checked first.
What to look for in a quote
- How VAT is shown, and which rate applies
- Whether testing, commissioning and paperwork are included

Mark Cross: your questions answered
Will a heat pump in Mark Cross need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Around 5 listed entries sit within 0.5 miles of central Mark Cross. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where necessary, we check with the local planning authority (for Mark Cross, normally Wealden council).
Does the Boiler Upgrade Scheme cover homes in Mark Cross?
Yes, if the home and the heat pump meet the scheme’s rules: Mark Cross is in England, where it applies. 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’re MCS certified.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and explain why.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.
How much does an air source heat pump cost?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme though not every home qualifies.
Do you cover Mark Cross?
Yes. We work in Mark Cross and the rest of East Sussex, as part of our area across London and the South East. For a fixed-price quote, ring 07833 053749, or email if that’s easier.
Which type of heat pump is right for my home?
Air-to-water heats radiators or underfloor heating and hot water; air-to-air heats rooms through indoor units and can cool them. Air-to-air does not heat hot water, and we explain which suits your home.

Heat pumps in Mark Cross: local notes
Valuation Office Agency council tax records put about 42% of homes across Mark Cross and its surrounding area before 1919, and about 75% 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. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Wadhurst Castle, roughly 3.2 miles east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.

Looking after it afterwards
Looking after the system is mostly common sense. Our tips:
- File the MCS certificate safely
- Book a yearly service
- Leave indoor units unobstructed
The warranty on the heat pump is the manufacturer’s, on its own terms. We go through the conditions with you, including any servicing they ask for.
Keep radiators and indoor units unobstructed so the heat can get into the room.
Leave it or put it right?
From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. If you are thinking about a heat pump, that date is worth knowing, though the right time also depends on your home and heating. Booking before summer means the work in Mark Cross is done before the hot weather.
The price reflects the work, not guesswork. That is why we look at the job first, from photos or on a survey, and why the quote is fixed before work begins.
