Air source heat pumps in Maple Cross

About our air source heat pumps in Maple Cross

Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. With air-to-air, hot water has to come from something else. The work covers air-to-water heat pumps, homes heated by oil, LPG or gas and underfloor heating, and common reasons people get in touch are checking whether planning permission is needed and comparing heat pump types.

In a place like Maple Cross, some homes are listed, because permitted development does not apply within the grounds of a listed building, so consent comes first.

Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

How the job changes from property to property

Hot water cylinders

Hot water from an air-to-water system is stored in a cylinder. The survey looks at where it can go particularly in homes with a combi boiler.

Air-to-air heat pumps

Since 2025, air-to-air heat pumps can also be permitted development in England, subject to the conditions. A unit used solely for cooling isn’t covered, so check with the council.

Owner checks or an engineer?

Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and ring us on 07833 053749 or send an email.

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. If you suspect a leak, switch the system off and call us.

What we do, step by step

The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Visits to Maple Cross are agreed with you in advance and planned so the job can be finished in one trip where possible.

  1. First we talk through the property and the current system.
  2. A heat loss survey is carried out, room by room.
  3. The design covers the heat pump, emitters, hot water and outdoor unit.
  4. A fixed-price quote explains the cost, the grant position and the VAT.
  5. Installation, commissioning and MCS registration complete the job.

Before we arrive

  • Give us access to the outside wall, roof or yard where the outdoor unit sits
  • Clear a path to the units and the space around them
  • Let us know if the building has a permit or sign-in process

Getting a price

Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, ring 07833 053749, or email if that’s easier.

Advice

Air source heat pumps around Maple Cross

About 5 listed entries lie within half a mile of central Maple Cross, May Cottage (grade II) among them. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the planning team at Three Rivers council, which typically handles Maple Cross. At about 20 miles from central London, Maple Cross sits inside the area we cover across London and the South East.

If your home is one of the older properties near Church of St Thomas of Canterbury, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Historic houses such as Chenies Manor House, about 3.7 miles north, are a reminder that listed homes need consent before a heat pump goes in.

Maple Cross questions

Do you cover smaller places like Maple Cross?

Yes. Maple Cross is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.

Can I get the Boiler Upgrade Scheme grant in Maple Cross?

Maple Cross is in England, where the Boiler Upgrade Scheme runs. 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 isn’t an add-on to a boiler. The installer applies, and we’re MCS certified.

How much does an air source heat pump cost?

For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales, and we confirm eligibility before you commit.

Do you provide F-Gas records?

Yes, always. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.

Do you protect the property while you work?

Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.

Do I need new radiators for a heat pump?

That depends on the room’s heat loss and the radiator’s size. We check them all during the survey and the quote shows what’s needed.

How soon will you get back to me?

The same working day. Then we agree a date that works for you, with a fixed price before work starts.

What air source heat pumps cannot fix

We will not sell you work that does not address the problem, so these are the things it won’t cover:

  • Planning decisions, which rest with the council
  • Any gas work on the existing boiler
  • Promising eligibility for the Boiler Upgrade Scheme

Not sure which it is? You can call 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll tell you honestly before booking.
