Air source heat pumps in Fleet Marston and nearby

Air source heat pumps in Fleet Marston, done properly

In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit cannot be used solely for cooling or sit within the curtilage of a listed building. We look at the planning position for your home during the survey. If the problem is deciding which kind of heat pump suits the home and wanting to stop using oil, LPG or gas for heating, we can help.

Older and listed homes in villages like Fleet Marston need extra care, and permitted development doesn’t cover listed buildings, so we check consent first.

For a fault on a system that may still be under warranty, send us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

Safe owner checks

Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.

Never try to top up, release or handle refrigerant yourself. 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 air conditioning won’t do

An honest diagnosis matters more to us than a booking, so here’s what air source heat pumps will not do:

  • A grant for a home that does not meet the scheme rules
  • Improving the building’s insulation
  • Planning approval where permitted development does not apply

Not sure which it is? You can call us on 07833 053749 or drop us a line and we’ll tell you honestly.

What the work covers

Fleet Marston questions

Is Fleet Marston in your area for air source heat pumps?

Yes. We work across London and the South East from our base in East Grinstead, and Fleet Marston is part of that. To start, call us on 07833 053749 or send an email with a few photos.

Is Fleet Marston 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.

Will you work on another installer’s system?

Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.

How much does an air source 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, and air-to-air systems are priced after a survey.

What does F-Gas certified mean?

For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book, and we are happy to show ours.

Can I get a grant for an air-to-air heat pump?

There is a £2,500 grant for air-to-air, but only under strict conditions. The system must replace the existing fossil-fuel heating, meet the home’s full heating demand, be installed by an MCS certified installer and be in a home.

Can you set up regular servicing?

Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.

After we’ve gone

Looking after it is simple, and it makes the next visit easier:

  • File the MCS certificate safely
  • Check what your manufacturer’s warranty asks of you
  • Leave indoor units unobstructed

Once commissioned, we register the installation with MCS and give you the certificate. File it with the warranty documents for future reference.

Book a service every year. Your manufacturer’s warranty terms may say something about servicing.

The process

Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. We agree a date with you and plan the visit to Fleet Marston so we arrive with what’s needed.

  1. We start with your plans and the property.
  2. We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
  3. You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
  4. Installation follows on the agreed dates.
  5. After commissioning, you get the MCS certificate and a handover.

Before we arrive

  • Tell us about access, such as roof hatches, high walls or locked plant areas
  • Arrange for someone to be there to let us in
  • Clear a path to the units and the space around them
