Air source heat pumps in Wych Cross
As an MCS certified installer, we fit air source heat pumps for homes in Wych Cross and the rest of East Sussex. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. Typical jobs include working out where a cylinder could go and an oil, LPG or gas boiler near the end of its life, on air-to-air heat pumps, air-to-water heat pumps and hot water cylinders.
For a home around Wych Cross that is off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, 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, as a manufacturer or a future engineer may ask to see them.

What you can do yourself, and what needs us
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and phone 07833 053749.
What we’re called out for in Wych Cross
Some homes heated by electric heaters or storage heaters consider a heat pump instead. A survey shows whether a heat pump suits the property and what would need to change, and we explain the grant position for your home.
Most people get in touch when they notice something like this:
- Radiators that may be too small for a heat pump
- Comparing heat pump types
- Not knowing whether a grant applies
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.
Comparing quotes
- How extra work would be agreed if they find something unexpected
- Whether you get F-Gas records where refrigerant is involved
- What the manufacturer’s warranty covers and for how long

Wych Cross questions
Is Wych Cross within the area you cover?
Yes. Wych Cross is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is planning permission needed for a heat pump in Wych Cross?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 3 buildings and structures within half a mile of the centre of Wych Cross. 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 normally the planning authority for Wych Cross.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded and F-Gas records kept where they apply.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
What we do, step by step
Protection comes first: dust sheets over floors and furniture near the work, and we ask before moving anything. After that, anything electrical is made safe and we start. The work on site takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes, and we tidy up before we leave. Rural lanes and tight entrances are worth mentioning before a visit to Wych Cross.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Plan for pets to be kept clear during the visit
- Clear a path to the units and the space around them
- Mention any parking restrictions near the property
Getting a price
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.

Heat loss surveys
Without a proper survey, a heat pump can be too big or too small, and both cause problems.
Air-to-water heat pumps
Flow temperatures are lower than with a typical boiler, so radiator sizes matter.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
