Your questions about air source heat pumps in Great Parndon
Do I need planning permission for a heat pump in Great Parndon?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Great Parndon holds about 10 listed buildings and structures. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Harlow council, which is normally the planning authority for Great Parndon first.
Will you come out to Great Parndon?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I get the Boiler Upgrade Scheme grant?
We check the scheme rules for your property before you go ahead. As the installer, we make the application where you qualify.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Can I do the refrigerant work myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Who is responsible for leak checks?
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 every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
What’s the price of a heat pump installation?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
How we handle air source heat pumps in Great Parndon
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. The work covers hot water cylinders, air-to-air heat pumps and underfloor heating, and the jobs we see most are deciding on the outdoor unit position and choosing between air-to-water and air-to-air.
Cottages and older homes near Great Parndon can lose heat faster, so a proper heat loss calculation matters. Sometimes insulating first makes more sense.
The records are your system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Air source heat pumps around Great Parndon
About 53% of homes across Great Parndon and its surrounding area date from 1945 to 1972, according to Valuation Office Agency council tax records, and the last census (2021) found about 46% of households in terraced houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important.
Every heat pump design starts with a room-by-room heat loss calculation. Older homes near Church of St Mary the Virgin may need extra checks for planning and heat loss before a heat pump is designed.

The process
The work area is kept tidy throughout, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the room and the outside wall help us plan a job near Great Parndon.
- It starts with a conversation about the home, the existing heating and your plans.
- 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.
- 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.
How to prepare
- Keep pets and children away from the work area

What owners can safely do
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
What a customer said
“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.”
