About our air source heat pumps in Moulsham
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. We’re often asked to deal with deciding on the outdoor unit position and deciding which kind of heat pump suits the home, on air-to-water heat pumps, radiator systems and air-to-air heat pumps.
Older homes around Moulsham can be draughty or have solid walls, so a proper heat loss calculation matters. Sometimes insulation first is the better investment.
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.

FAQs for Moulsham
Does the Boiler Upgrade Scheme cover homes in Moulsham?
Moulsham is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. The installer applies, and we are MCS certified.
Can I fit a heat pump in Moulsham without planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Moulsham sits inside the Chelmsford Moulsham Street Conservation Area. 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 do not 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 the local planning authority (for Moulsham, usually Chelmsford council).
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll tell you what to do first.
How long will it take to install a heat pump?
It takes a few days on site, depending on the cylinder, the radiators and the pipework involved. How much of the heating changes decides most of the time and the timing is set out with your quote.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.
What’s the difference between air-to-water and air-to-air heat pumps?
The right choice depends on the property and what you need. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases. We explain the options after the survey.
What happens if it’s left?
Getting the sizing wrong causes problems that are hard to fix later. Doing the survey properly from the start avoids that. Waiting rarely makes an air conditioning problem smaller.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re unsure, ring 07833 053749 or send an email and we’ll give you an honest view and a fixed price.

Air source heat pumps around Moulsham
About 41% of homes across Moulsham and its surrounding area have been built since 2000, according to Valuation Office Agency council tax records, and Census 2021 figures found about 51% of households live in flats. Better insulated, newer homes are often a good match for a heat pump. In flats, space for an outdoor unit and a cylinder can be limited, and the lease and freeholder come into it, so air-to-air is sometimes the better fit.
If your home is listed, like Hylands about 1.7 miles south-west, listed building consent comes before any heat pump work. Older homes near Church of St John the Evangelist may need extra checks for planning and heat loss before a heat pump is designed.

What we do, step by step
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, which takes from a couple of days to around a week, depending on the system and how much of the heating changes. Around Moulsham, access is usually simple, though gates and garden access are worth mentioning.
- First we find out about the property, the heating you have now and what you’re hoping for.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear the space around the indoor unit, or where it will go
- Mention any roof access, ladders or high-level work

What owners can safely do
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and give us a ring on 07833 053749 or send an email.
