Air source heat pumps for homes and businesses in Mistley
We install air source heat pumps in Mistley and across Essex, and we are MCS certified. 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. Common call-outs are for working out where a cylinder could go and deciding which kind of heat pump suits the home, on radiator systems, hot water cylinders and air-to-water heat pumps.
Homes around Mistley normally have room outside for a heat pump, so the design focuses on heat loss and radiators.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Owner checks or an engineer?
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and ring 07833 053749 or use the quote form.
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.

Heat pumps in Mistley: local notes
At about 1 mile from the coast, Mistley is close enough for sea air to matter. Salt air is hard on outdoor units, so a heat pump near the sea needs a sensible position and regular checks, and some models offer corrosion protection for coastal sites. The last census (2021) found about 75% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. The Manningtree and Mistley Conservation Area is within about a third of a mile of the centre of Mistley. On the National Heritage List, around 9 entries fall within 0.5 miles of the middle of Mistley; Home Farmhouse (grade II) is one. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
If your home is listed, like Castle House about 4 miles west, listed building consent comes before any heat pump work. Live in one of the older houses around Site of Old St Mary's Church? Expect the survey to look closely at heat loss and at the building’s planning status.

Questions from Mistley
Can I get the Boiler Upgrade Scheme grant in Mistley?
Yes, if the home and the heat pump meet the scheme’s rules: Mistley is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You don’t apply yourself: the MCS certified installer does, which is us.
Do you cover smaller places like Mistley?
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.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
When will I hear back?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
System by system
Radiators and underfloor heating
If radiators need upsizing, the quote lists them, so you know the full scope.
Air-to-water heat pumps
Air-to-water systems take heat from the air and put it into your central heating and hot water. It replaces the boiler as the main heat source, and is MCS certified when we install it.
Let and managed properties
Keeping records across a portfolio is half the battle. Each visit is written up, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Whether it’s one property or many, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
How it works
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. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the existing unit help with repairs and servicing in Mistley.
