We're an independent comparison service helping London homeowners find the right Air Source Heat Pump installer. No pushy sales calls. No hidden costs. Just honest advice and access to quality professionals who know London properties inside out.
Let's be straight with you. Heat pump installation in London typically costs more than in other parts of the UK. Why? Higher labor rates, more complex properties, and trickier access in dense urban areas.
But here's the good news: the £7,500 government grant doesn't change based on location. London homeowners get the exact same grant as everyone else, which makes a huge difference to the final price.
| Item | Cost Range |
|---|---|
| Air Source Heat Pump (London) | £10,000 - £15,000 |
| Ground Source Air Source Heat Pump | £18,000 - £35,000 |
| Government Grant Deduction | -£7,500 |
| Your Final Cost (Air Source) | £2,500 - £7,500 |
| Your Final Cost (Ground Source) | £10,500 - £27,500 |
London properties come with unique challenges that can push costs higher:
All London installers in our network hold MCS certification. That's not optional – it's required to access the £7,500 grant. MCS certification means the installer has met strict quality standards and their work is independently inspected.
Our installers understand London property types intimately. They've worked on Victorian terraces in Clapham, flats in Canary Wharf, and period conversions in Dulwich. They know local planning requirements and conservation area rules. This matters more than you might think.
When you compare up to 3 installers, you're creating competition for your business. That competition drives better prices. You're under no obligation to accept any quote. If the numbers don't work for you, walk away.
The installers handle the entire £7,500 grant process for you. You don't need to understand the paperwork or navigate government websites. They submit everything, chase approvals, and the grant gets paid directly to them, reducing your final bill.

These are everywhere in North, South, and East London. Clapham, Balham, Islington, Hackney – you know the type. Beautiful properties, but they come with challenges.
The walls are often solid brick with no cavity insulation. Single-glazed sash windows are common. These properties leak heat like a sieve. Before installing a Air Source Heat Pump, you might need to upgrade insulation and get better windows. Not always, but often.
Your radiators probably need upgrading too. Heat pumps work at lower temperatures than gas boilers, so you need bigger radiators to compensate.
Typical cost: £11,000 - £14,000 (before grant)
After £7,500 grant: £3,500 - £6,500
Can you get a Air Source Heat Pump in a London flat? Sometimes yes, sometimes no.
You need permission from your freeholder or management company. Some say yes, some say no. You need outdoor space for the unit – a balcony, roof access, or ground-level area. Noise is a consideration because you've got neighbors nearby.
You also need space inside for a hot water cylinder. Many London flats use combi boilers precisely because they're small. Adding a cylinder back can be tricky in a tight space.
Typical cost: £10,000 - £13,000 (before grant)
After £7,500 grant: £2,500 - £5,500
These are the easiest. Properties built in the last 20 years are usually well-insulated. Double glazing is standard. Underfloor heating is common, which works beautifully with Air Source Heat Pumps.
Installation is straightforward and costs less because less preparation work is needed.
Typical cost: £9,000 - £12,000 (before grant)
After £7,500 grant: £1,500 - £4,500
If you live in a conservation area like Dulwich, Highgate, or parts of Greenwich, you might need planning permission. Listed buildings definitely need listed building consent.
The outdoor unit needs to be positioned carefully so it doesn't affect the building's character. Our installers have done this many times. They know how to work with local planning departments and what's likely to get approved.
Typical cost: £12,000 - £16,000 (before grant)
After £7,500 grant: £4,500 - £8,500

Yes, but with conditions. You need outdoor space for the unit (balcony, roof, ground level). Freeholder permission is required. Noise considerations for neighbors matter. You need space for a hot water cylinder inside.
Not all flats are suitable. A free survey will confirm if yours works.
Modern Air Source Heat Pumps are quiet (40-50 decibels – like a fridge). They must be 1 meter from your neighbor's boundary. Installers position the unit to minimize impact. Acoustic barriers can be added if needed.
Yes, especially with the £7,500 grant. Heat pumps are 300 percent efficient (gas boilers 90 percent). Lower running costs if on the right tariff. Increases property value. Future-proof as gas boilers are being phased out.
