Air source heat pumps for homes and businesses in Harestock
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. Air-to-air systems don’t heat hot water, so you’ll need another way to do that. The work covers underfloor heating, air-to-air heat pumps and hot water cylinders, and common reasons people get in touch are questions about listed buildings or conservation areas and replacing a combi boiler with a heat pump.
Cottages and older homes near Harestock can lose heat faster, so a proper heat loss calculation matters. Sometimes insulating first makes more sense.
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, as a manufacturer or a future engineer may ask to see them.

Why act early in Harestock
From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. If you’re thinking about a heat pump, that date is worth knowing alongside your own plans for the property. A system that’s left with a fault, or without a service, normally costs more to run.
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we will go through it with you.

Looking after your system
A little care keeps the system in better shape. We recommend:
- Clear leaves and debris from the outdoor unit
- Ask about the grant before you commit
- Diary the next service
If you were eligible for a grant, we handle the application and keep you updated since the grant goes through the installer.
Do not cover radiators with furniture or heavy curtains, as the system relies on them giving out heat.
How the visit works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. On site, it 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. Visits to a place like Harestock are planned ahead, so we arrive with what the job needs.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Getting ready for the visit
- Clear access to the fuse board
- Keep pets out of the rooms we are working in
- Unlock any gate, garage or side passage we need

Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price before any work starts.
Advice
FAQs for Harestock
Will you come out to Harestock?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is the heat pump grant available in Harestock?
Yes, if the home and the heat pump meet the scheme’s rules: Harestock 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. As an MCS certified installer, we apply for it on your behalf.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water heats radiators or underfloor heating and hot water; air-to-air heats rooms through indoor units and can cool them. With air-to-air, hot water needs another source, and we explain which suits your home.
Homes in Harestock and heat pumps
About 47% of homes in the Harestock area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 72% of households in detached or semi-detached houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. Harestock is about 61 miles from central London, well within the area we cover from our base in East Grinstead.
A heat loss calculation decides the size of heat pump your home needs. If your home is one of the older properties near Saint Barnabas, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
