Air source heat pumps across Hartley

For landlords and property managers

For anyone managing more than one building, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so the files stay tidy.

Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side and send the records to whoever needs them.

Air source heat pumps for homes and businesses in Hartley

Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. The technology is close to air conditioning, which is why we install both, and air-to-air heat pumps are sometimes simply called air conditioning. The work covers air-to-air heat pumps, radiator systems and underfloor heating, and people most often call us about questions about listed buildings or conservation areas and deciding which kind of heat pump suits the home.

Cottages and older homes near Hartley can lose heat faster, so a proper heat loss calculation matters. Sometimes insulation first is the better investment.

AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Your questions about air source heat pumps in Hartley

Will a heat pump in Hartley need planning permission?

That depends on the building and where the outdoor unit goes. A conservation area takes in the middle of Hartley. 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 Dartford council, which is usually the planning authority for Hartley first.

Does the Boiler Upgrade Scheme cover homes in Hartley?

Yes, if the home and the heat pump meet the scheme’s rules: Hartley is in England, where it applies. 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 is not an add-on to a boiler. You don’t apply yourself: the MCS certified installer does, which is us.

Do you offer emergency call-outs?

Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we will advise on what to do next.

Are you F-Gas certified?

F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.

Which type of heat pump is right for my home?

Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms. The survey helps decide. We install both types.

Can I fit air conditioning or a heat pump myself?

The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.

Do I need to service the system to keep the warranty?

Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.

Homes in Hartley and heat pumps

VOA council tax data date about 42% of homes across Hartley and its surrounding area to the post-war years, 1945 to 1972, and the last census (2021) found about 76% 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. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.

Historic houses such as Cobham College, about 3.9 miles east, are a reminder that listed homes need consent before a heat pump goes in. Older homes near Church of Saint Mary may need extra checks for planning and heat loss before a heat pump is designed.

How the visit works

Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes from a couple of days to around a week, depending on the system and how much of the heating changes. Because we plan from photos or a survey, a job in Hartley can typically be finished in one visit.

  1. You tell us about the home and what you want from a heat pump.
  2. The survey checks heat loss, emitters, hot water and the outdoor unit position.
  3. We recommend air-to-water or air-to-air and check the grant position.
  4. Installation follows on the agreed dates.
  5. The job ends with commissioning, the MCS certificate and a walk through the controls.

How to prepare

  • Make sure someone can let us in at the agreed time
  • Mention any parking restrictions near the property
  • Tell us about access, such as roof hatches, high walls or locked plant areas

How to get a quote

Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Air-to-air heat pumps

Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. Cooling-only units are not included, so check with the council.

The Boiler Upgrade Scheme

Only one grant is available per property, and it can’t replace a low-carbon system. Hybrids are excluded.

What affects the quote in Hartley

You’ll get a fixed price before any work starts. It takes into account:

  • The equipment or parts the job needs
  • The distance and route between the indoor and outdoor units
  • The size of the job

What you pay reflects the actual work. That’s why every job is looked at first, and the price is agreed before we start.

Helping us quote

When you call or email, these details help:

  • Where the property is and what kind of building it is
  • A few photos of the room and the wall the unit is on, or will go on
  • The paperwork from the last service, if you have it

Quotes don’t take long. Send a few details and pictures, and we reply the same working day. Where a survey is needed, we arrange a time that suits you.

A customer’s words

“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.”
