The process
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes a few days for most air-to-water installations, with air-to-air systems often quicker. Visits to King Street are agreed with you in advance and planned so the job can be finished in one trip where possible.
- First we talk through the property and the current system.
- We measure heat loss for every room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- Cost, grant and VAT appear on one fixed-price quote.
- We install, commission and register the system under MCS.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Let us know if the building has a permit or sign-in process
- Tell us about parking and loading

Advice
Air source heat pumps in King Street
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses, and for air-to-air systems we confirm the VAT on your quote. Please treat this as general information rather than tax advice. The work covers hot water cylinders, homes heated by oil, LPG or gas and air-to-air heat pumps, and people most often call us about plans to switch to electric heating with a heat pump and no space for a hot water cylinder.
Space for an outdoor unit is rarely an issue near King Street, so the design comes down to heat loss, radiators and hot water.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Heat pumps in King Street: local notes
Census 2021 figures found about 87% 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. About 11 listed entries lie within half a mile of central King Street, King Street Farmhouse (grade II) among them. Where a home is affected, the outdoor unit position is settled with the local planning authority (typically Epping Forest council) before the heat pump design is finished.
Ingatestone Hall, roughly 5 miles south-east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings. If your home is one of the older properties near Church of All Saints, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
King Street is about 6 miles north of Brentwood, in Essex. King Street gets the same approach as every job we take on: diagnosis first, a fixed price and proper paperwork when we have finished. Across Essex, we cover 644 places, and King Street is one of them. For properties nearby, see our London page (22 miles or so).

King Street: your questions answered
Is King Street within the area you cover?
Yes, and the size of the place makes no difference to how we work. We are 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 King Street?
King Street is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. As an MCS certified installer, we apply for it on your behalf.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Should I choose air-to-water or air-to-air?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms. The survey helps decide. Both are part of what we install.
Do I need planning permission for a heat pump?
In England, many air source heat pumps on houses can be permitted development provided the conditions are met. The outdoor unit must be 1.5 m³ or less, comply with MCS 020(a), not be cooling-only and not be within a listed building’s curtilage.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in King Street and across Essex. Tell us who should receive the paperwork.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Aftercare tips
Every system needs looking after, and most of it is easy. Our tips:
- Keep the MCS certificate with the manufacturer’s paperwork
- Keep to regular servicing
- Leave space around the outdoor unit
Should you have questions after the install, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk and we will look into it. A yearly service is a good habit.
Have the system serviced regularly. Check the manufacturer’s terms, as they may include servicing conditions.
How the job changes from property to property
Hot water cylinders
An older cylinder may not suit a heat pump, and we explain whether yours can stay.
Outdoor unit position and planning
Permitted development conditions in England include an outdoor unit of no more than 1.5 m³, compliance with MCS 020(a), and use for more than cooling alone. Listed building curtilages are excluded.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
