How we handle air source heat pumps in Charlton
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. The work covers air-to-air heat pumps, radiator systems and air-to-water heat pumps, and the jobs we see most are questions about listed buildings or conservation areas and moving away from fossil-fuel heating.
If your home in or near Charlton is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

FAQs for Charlton
Is Charlton within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is a heat pump in Charlton permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The centre of Charlton is in the Charlton Conservation Area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where necessary, we check with the local planning authority (for Charlton, usually Chichester council).
Is there VAT on a heat pump?
For homes, currently none: HMRC zero-rates heat pumps installed in residential accommodation until 31 March 2027, and 5% applies after that. Businesses and hotels pay the standard rate, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Will I get records for the system?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Which accreditations do you hold?
As the law requires for refrigerant work, we’re an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.

What else we do in Charlton
Rented and managed buildings
From a single flat to a whole estate, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
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 on a regular cycle.
Keeping the system healthy
A little care keeps the system in better shape. We recommend:
- Leave indoor units unobstructed
- Look at insulation alongside the heat pump
- Read the manufacturer’s warranty terms for your brand
If you were eligible for a grant, we handle the application and keep you updated since the grant goes through the installer.
Keep insulation and draught-proofing in good order because it reduces the heat the system needs to supply.

The process
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. After that, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. We plan the trip to Charlton around you.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- 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
- Mention any roof access, ladders or high-level work
- Arrange for someone to be there to let us in
- Mention any managing agent or landlord rules we need to follow
