Air source heat pumps in Mortlake, done properly
Many air source heat pumps can be installed as permitted development in England, without a planning application. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We look at the planning position for your home during the survey. Common call-outs are for checking eligibility for a heat pump grant and radiators that may be too small for a heat pump, on radiator systems, hot water cylinders and air-to-air heat pumps.
Homes in Mortlake are often flats and terraces, where outside space is limited, and that decides which kind of heat pump works. Air-to-water needs room for the outdoor unit and typically a cylinder, while air-to-air units take less room.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

When to call us in Mortlake
A common reason is wanting to stop burning gas, oil or LPG. With a heat pump, the heat comes from the air outside and the system runs on electricity and that’s the appeal for many households.
Keep an eye out for any of the following:
- Checking emitters for a heat pump
- Not knowing whether a grant applies
- A boiler that is getting old
Historic houses such as Chiswick House, about 1.3 miles north, are a reminder that listed homes need consent before a heat pump goes in.
What your quote should include
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- What the manufacturer’s warranty covers and for how long
- Whether they hold F-Gas company certification, not just individual qualifications

FAQs for Mortlake
Does the Boiler Upgrade Scheme cover homes in Mortlake?
Mortlake is covered, as the scheme runs across England and Wales. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we’re MCS certified.
Can you fit air conditioning in a London flat in Mortlake?
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.
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, and you can phone us on 07833 053749 or email us to book it.
Do you offer emergency call-outs?
Yes. Our emergency line runs 24/7 for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water heats radiators or underfloor heating and hot water; air-to-air heats rooms through indoor units and can cool them. Air-to-air doesn’t heat hot water and the survey helps decide.
What does an air-to-water heat pump cost?
Air-to-water systems are £8,000–£16,000 (0% VAT on homes), before any grant. Your price depends on the survey, the emitters and the hot water and the quote is fixed.
When something else is needed
In fairness, there are a few things this work will not fix:
- Improving the building’s insulation
- Planning approval where permitted development doesn’t apply
- Promising eligibility for the Boiler Upgrade Scheme
Not sure which it is? You can call 07833 053749 or use the quote form and we will tell you honestly before you book.

How the job changes from property to property
Heat loss surveys
A heat loss survey measures how much heat each room loses on a cold day. Everything else is sized from it.
The Boiler Upgrade Scheme
The Boiler Upgrade Scheme covers England and Wales: £7,500 for air-to-water (and ground source), and £2,500 for air-to-air with strict conditions. The application goes through the installer.
Homes in Mortlake and heat pumps
About 58% of homes in the Mortlake area were built before 1919, according to VOA council tax data. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Homeowners near Mortlake station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.
