About our air source heat pumps in Chalk End
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. The work covers underfloor heating, radiator systems and air-to-air heat pumps, and common reasons people get in touch are ageing boilers that will need replacing and choosing between air-to-water and air-to-air.
Space for an outdoor unit is rarely an issue near Chalk End, so the design comes down to heat loss, radiators and hot water.
We’re 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.

Air source heat pumps in Chalk End: the local picture
About 52% of homes in Chalk End and the neighbourhoods around it date from 1945 to 1972, according to Valuation Office Agency council tax records, and Census 2021 figures found about 63% of households in detached or semi-detached houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Houses typically have space for an outdoor unit and a hot water cylinder.
If your home is one of the older properties near Church of St Andrew, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Pricing air source heat pumps in Chalk End
Typical ranges are on our prices page, but every job is priced on its own. The quote depends on:
- A single visit or a regular plan
- The brand, model and parts involved
- The size of the job
The price reflects the work, not guesswork. That’s why every job is looked at first, and why the quote is fixed before work begins.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Your installation or service records
- Where the outdoor unit is, or where you’d like it
- Where the property is and what kind of building it is
Want a quote for air source heat pumps? Please give us a ring on 07833 053749 with a few details about the property. We’ll explain what we’d recommend and why, then send a fixed-price quote before you commit to anything.
Rented and managed buildings
Portfolio owners often want one contractor and one number. We work across London and the South East, so a run of properties can go into one programme and kept to a regular schedule.
Facilities teams in offices, schools and public buildings book us too in Chalk End and across Essex. Work can be phased by floor, zone or building to keep disruption down.
How the visit works
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes from a couple of days to around a week, depending on the system and how much of the heating changes. Work in Chalk End is booked in advance at a time that suits you.
- First, a chat about the property and your goals for the heating.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
Before we arrive
- Clear access to the fuse board
- Keep pets out of the rooms we’re working in
- Clear a path to the units and the space around them

Advice
Questions from Chalk End
Do I need planning permission for a heat pump in Chalk End?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of Chalk End holds about 3 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 Chelmsford council, which is usually the planning authority for Chalk End first.
Does the Boiler Upgrade Scheme cover homes in Chalk End?
Yes, the scheme covers homes in England, including Chalk End, if they qualify. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. You don’t apply yourself: the MCS certified installer does, which is us.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
What does F-Gas certified mean?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
What does an air-to-water heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder. Air-to-air is priced after a survey.
How long does a heat pump installation take?
A typical installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We plan the work so you’re without heating for as little time as possible, and we explain it in advance.
What you can do yourself, and what needs us
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
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
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
