Air source heat pumps across Erith

About our air source heat pumps in Erith

For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. If you’re dealing with choosing between air-to-water and air-to-air and questions about the Boiler Upgrade Scheme, we can sort it out.

Homes in Erith are often flats and terraces, where outside space is limited, which affects which heat pump suits. An air-to-water system needs space outside and normally a hot water cylinder inside, while an air-to-air system needs less space.

Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Homes in Erith and heat pumps

London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.

Older homes near Christ Church may need extra checks for planning and heat loss before a heat pump is designed.

Different systems, different jobs

Air-to-water heat pumps

Air-to-water systems take heat from the air and put it into your central heating and hot water. It takes over from the boiler, and is MCS certified when we install it.

Air-to-air heat pumps

Air-to-air heat pumps warm rooms through indoor units and can cool them in summer. Hot water needs a separate source, so that has to come from elsewhere.

How it works

On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. Before a visit in Erith, we ask where the van can stop and how we reach the outdoor unit.

  1. You tell us about the home and what you want from a heat pump.
  2. We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
  3. We recommend air-to-water or air-to-air and check the grant position.
  4. We install the heat pump and connect it up.
  5. The job ends with commissioning, the MCS certificate and a walk through the controls.

Before we arrive

  • Mention any managing agent or landlord rules we need to follow
  • Keep pets out of the rooms we are working in
  • Clear the space around the indoor unit, or where it will go

Advice

Common problems we fix in Erith

Many people look at heat pumps when an oil, LPG or gas boiler is getting old. Planning the change before the boiler fails gives you time to survey, design and apply for any grant, rather than rushing a replacement in winter.

The things we’re asked about most include:

  • An oil, LPG or gas boiler near the end of its life
  • Questions about listed buildings or conservation areas
  • Checking eligibility for a heat pump grant

Historic houses such as Hall Place and Gardens, about 2.3 miles south, are a reminder that listed homes need consent before a heat pump goes in.

Questions to ask before booking

  • What the manufacturer’s warranty covers and for how long
  • Whether they looked at the job before pricing it
  • Whether they hold F-Gas company certification, not just individual qualifications

Why it’s worth doing now in Erith

Planning rules have specific conditions. Checking the position for your home at the survey stage avoids surprises later covering listed buildings, conservation areas and any Article 4 direction. Approvals for flats in Erith can take longer than the install itself.

Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we’ll explain each part.

Erith questions

Is a heat pump in Erith permitted development?

The answer turns on the property and where the outdoor unit would sit. Central Erith is a short walk from the Lesney Park Road Conservation Area. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Bexley council, normally the authority for Erith.

Is the heat pump grant available in Erith?

Yes, the scheme covers homes in England, including Erith, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You don’t apply yourself: the MCS certified installer does, which is us.

Will I get records for the system?

Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.

Which accreditations do you hold?

AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.

What does an air-to-water heat pump cost?

Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken 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.

Do you cover Erith?

Yes. Our engineers work in Erith, as part of our area across London and the South East. We’re based in East Grinstead, West Sussex.

How much time does a heat pump install need?

The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. We confirm the timing after the survey, so ring us on 07833 053749 to arrange one.
