What a heat pump looks like in Rainham
The Valuation Office Agency’s council tax figures show about 47% of homes in and around Rainham date from 1919 to 1939, and the 2021 Census found about 37% of households in terraced houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. In a terrace, the outdoor unit position and the MCS noise check need particular care. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If your home is one of the older properties near Church of St Helen and St Giles, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. With Rainham Hall about 0.2 miles west, it’s worth asking whether your own home is listed before planning a heat pump.
Rainham is about 4 miles south of Romford, in Greater London. Rainham gets the same approach as every job we take on: a look at the job first, a fixed-price quote and written records at the end.

Our nearest recent job to Rainham was on Greenwich High Road, Greenwich (SE10), about 9 miles west: installing a Mitsubishi Electric wall-mounted unit in the retail area and a second unit in the stockroom and office.

Air source heat pumps in Rainham, done properly
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, 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 plans to switch to electric heating with a heat pump and checking emitters for a heat pump, we can help.
For flats in Rainham, the lease, the freeholder and the rules for flats all come into it. The planning rules for flats are stricter than for houses, so we check the position before we design.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

How the job changes from property to property
Hot water cylinders
The cylinder size depends on how much hot water the household uses.
VAT on heat pumps
Heat pumps in homes carry 0% VAT until 31 March 2027, and 5% after that following HMRC’s rules on energy-saving materials. Businesses pay the standard rate.
Looking after it afterwards
A little care keeps the system in better shape. We recommend:
- Keep radiators clear
- Clear leaves and debris from the outdoor unit
- Keep up with insulation and draught-proofing
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork for future reference.
Book a service every year. Your manufacturer’s warranty terms may say something about servicing.

Questions from Rainham
Is the heat pump grant available in Rainham?
Rainham is covered, as the scheme runs across England and Wales. 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.
Can I fit a heat pump in Rainham without planning permission?
It depends on the property. There’s a conservation area, the Rainham Conservation Area, close to central Rainham. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Rainham, typically Havering council).
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for breakdowns that cannot wait. Ring 07833 053749 any time and explain the problem.
What warranty do I get?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
What does an air-to-water heat pump cost?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before booking anyone, and we’re happy to show ours.
How long does a heat pump installation take?
An installation takes from a couple of days to around a week, depending on the system and how much of the heating changes. The survey lets us set a firm programme, and you can phone us on 07833 053749 to book it.
What we do, step by step
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, which takes a few days for most air-to-water installations, with air-to-air systems often quicker. Before a visit in Rainham, we ask where the van can stop and how we reach the outdoor unit.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Have the make and model of any existing unit to hand
- Make sure someone can let us in at the agreed time

Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price before any work starts.
Related advice
Owner checks or an engineer?
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
From one of our customers
“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.”
