Air source heat pumps in Halstead
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. The work covers air-to-air heat pumps, homes heated by oil, LPG or gas and radiator systems, and common reasons people get in touch are working out whether radiators need upsizing and an oil, LPG or gas boiler near the end of its life.
Around Halstead, most people asking about heat pumps have a gas boiler now. We survey the heat loss, radiators, hot water and the outdoor unit position, then design the system.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

Landlords, agents and facilities managers
If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so each one has its own history.
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
What a heat pump looks like in Halstead
At about 44 miles from central London, Halstead sits inside the area we cover across London and the South East. The Halstead Town Centre Conservation Area is within about a third of a mile of the centre of Halstead. Historic England lists about 118 buildings and structures within half a mile of the centre of Halstead, including Parish Church of St Andrew (grade I). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
Historic houses such as Hedingham Castle, about 3.8 miles north-west, are a reminder that listed homes need consent before a heat pump goes in.
Halstead is about 5 miles north-east of Braintree, in Essex. We cover Halstead for air source heat pumps and across the rest of Essex. Our Essex coverage runs to 644 places, and Halstead is one of them. There’s also a page for London, about 44 miles away.
If your postcode is in CO9, we can take the job on. Halstead is on the A131 and A1124, so it’s easy for us to get to for surveys and visits.

The process
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we have done. Pictures of the space, the fuse board and the outside wall are a good start for a job in Halstead.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Clear a path to the units and the space around them
- Unlock any gate, garage or side passage we need
- Plan for pets to be kept clear during the visit

The things we’re asked about most are:
- Questions about the Boiler Upgrade Scheme
- Plans to switch to electric heating with a heat pump
- Working out whether radiators need upsizing
Period properties close to Congregational Church can suit a heat pump, though insulation and any heritage protection are checked first.

Common questions in Halstead
Is the heat pump grant available in Halstead?
Halstead is in England, where the Boiler Upgrade Scheme runs. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
Can you do air source heat pumps in Halstead?
Yes. We work across London and the South East from our base in East Grinstead, and Halstead is part of that. Just ring 07833 053749 or email us with a few details.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Which brands do you work with?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Should I choose air-to-water or air-to-air?
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 accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
