FAQs for Lower Morden
Is the heat pump grant available in Lower Morden?
Lower Morden is covered, as the scheme runs across England and Wales. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. As an MCS certified installer, we apply for it on your behalf.
Do I need permission to put air conditioning in my flat in Lower Morden?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Does servicing affect my warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Do you cover Lower Morden?
Yes. Lower Morden is part of the area we cover, within the South East and London area we cover. We’re based in East Grinstead, West Sussex.
Which brands do you work with?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Air source heat pumps in Lower Morden
We begin with a room-by-room heat loss survey. That tells us how much heat the home needs, room by room, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb isn’t good enough. The work covers underfloor heating, homes heated by oil, LPG or gas and air-to-water heat pumps, and the jobs we see most are checking whether planning permission is needed and choosing between air-to-water and air-to-air.
In a flat in Lower Morden, the lease and the freeholder typically decide where a heat pump can go. The planning rules for flats are stricter than for houses, so we check the position before we design.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Air source heat pumps in Lower Morden: the local picture
VOA council tax data show about 85% of homes in the Lower Morden area date from 1919 to 1939, and the 2021 Census found about 43% of households in terraced houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important. In London, outside space and the rules for flats often decide which kind of heat pump suits.
If your home is listed, like Southside House about 2 miles north, listed building consent comes before any heat pump work. Older homes near St Martin's may need extra checks for planning and heat loss before a heat pump is designed.

What happens if it’s left?
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases, and we explain which fits your home. If a lease or managing agent is involved in Lower Morden, start the conversation early.
What you pay depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. We give you a fixed price before any work starts, so you know where you stand.

How it works
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. If your building in Lower Morden has a managing agent, a concierge or sign-in rules, mention them when you book.
- First we talk through the property and the current system.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- We install, commission and register the system under MCS.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Mention any roof access, ladders or high-level work
- Keep pets and children away from the work area
Getting a quote
Getting a quote is straightforward. Call or email with a few details and we will come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.

Fixed-price quotes for air source heat pumps in Lower Morden
Our prices page gives typical ranges, but every job is priced on its own. The quote depends on:
- The distance and route between the indoor and outdoor units
- Whether it’s a simple split or a larger system
- The number of rooms, units or zones
A single unit or a whole estate, we price it on the same basis: the work involved, the access and the equipment. You’ll have a fixed price before any work starts, and the quote sets out the VAT.
Asking for a quote
What to send for a quote:
- Photos showing the indoor unit and the space around it
- A short video of any fault, such as a noise or a flashing light
- The postcode and whether it’s a home, flat or business
Published ranges are a starting point; the quote is built on your property, because every property is different. Once we’ve looked at the job, from pictures or on a survey, you get a fixed price. To get going, call us on 07833 053749 or write to us at info@aircondoctor.co.uk.
