Heat Pump Installation in Greenwich: What You Need to Know
Heat pump installation in Greenwich is often viable for houses and some larger owner-occupied properties, but SE10 still needs detailed survey work because the housing stock is mixed and site sensitivity can be higher. Energy Saving Trust says a typical air source heat pump costs around £11,000 before grant support, so survey accuracy still matters financially.
Greenwich is not just one housing type. Some homes are straightforward candidates, while others involve tighter plots, heritage sensitivity, or more limited ownership control that changes what is practical.
Is Your Greenwich Home Suitable for a Heat Pump?
Many Greenwich houses are suitable for a heat pump, while flats and tighter conversions are usually more constrained because of space and ownership issues. Nesta says 80% to 90% of UK homes already have enough insulation to run a heat pump, and in SE10 the real question is often external siting and internal layout.
The strongest local candidates are usually:
- Houses with workable garden or side space.
- Owner-occupied homes replacing older boilers.
- Properties where solar may also be practical.
Greenwich Property Types at a Glance
| Property Type | Heat Pump Suitability | Solar PV Suitability | Notes |
|---|---|---|---|
| Terraced house | Medium-High | Medium | Often viable with careful siting |
| Larger family home | High | Medium-High | Good fit for integrated upgrade |
| Flat or conversion | Low | Low-Medium | Space and control are typical barriers |

Planning Permission in Greenwich
Planning permission in Greenwich can be more sensitive than in many outer areas because parts of SE10 have stronger heritage and visual considerations, so unit siting needs to be taken seriously. MCS reported more than 30,000 certified heat pump installations in the first half of 2025, but planning-sensitive urban sites still demand better up-front review than average.
Some standard houses may still fall under permitted development, but we check the property-specific constraints before recommending the final design route.
The BUS Grant in Greenwich: How to Claim £7,500
Greenwich homeowners may qualify for the BUS grant of £7,500 towards an air source heat pump, subject to eligibility, and the installer manages the application. GOV.UK confirms that qualifying air source heat pump systems remain eligible for £7,500 in England, which is still a significant contribution to many SE10 retrofit budgets.
To qualify, the property needs a valid EPC and no relevant outstanding insulation recommendations. Electromatic handles the application as part of the install process so the claim is coordinated with the project.

ASHP + Solar: The Greenwich Combo
The ASHP and solar combination can work well in Greenwich where the property is a house with usable roof area and clear ownership. Energy Saving Trust says the average domestic solar system is around 3.5kWp, which is a practical benchmark for suitable SE10 homes rather than flats or denser conversions.
This route is strongest when:
- The property is a house.
- The roof has practical solar capacity.
- The owner wants to offset part of the heat pump’s electricity demand.

Heat Pump Running Costs in Greenwich
Heat pump running costs in Greenwich depend mainly on heat loss, emitter sizing, and controls, but a properly designed system can still compare well with gas while lowering carbon materially. Using Ofgem April 2026 planning prices of 24.5p/kWh for electricity and 7.4p/kWh for gas, design quality remains the main variable.
| Heating System | Annual Running Cost* | CO2 per Year |
|---|---|---|
| Gas boiler (new) | £1,100-1,400 | 2.4-3.0 tonnes |
| Air source heat pump | £900-1,200 | 0.6-0.9 tonnes |
| ASHP + Solar PV (4kW) | £500-800 | 0.3-0.5 tonnes |
*Based on Energy Saving Trust typical UK household data, Ofgem April 2026 prices (electricity 24.5p/kWh, gas 7.4p/kWh). Actual costs depend on property size, insulation, and energy usage.
How Electromatic Can Help Greenwich Homeowners
Electromatic is based in Sunbury-on-Thames, around 24 miles from Greenwich, so SE10 homeowners still get a nearby regional installer with London-wide coverage. MCS recorded more than 170,000 certified renewable installations in the first half of 2025, and the most successful projects usually begin with realistic site review and clear grant compliance.

Frequently Asked Questions — Heat Pumps in Greenwich
Greenwich homeowners usually ask about house suitability, planning sensitivity, and whether solar should be installed at the same time. MCS data showing more than 30,000 certified heat pump installations in the first half of 2025 confirms the technology is well established, but site-specific design still decides the outcome.
How much does a heat pump cost in Greenwich?
Typical suitable Greenwich projects cost around £10,000-14,000 before the BUS grant. After the £7,500 grant, subject to eligibility, many homeowners land around £5,000-7,500 depending on layout and complexity.
Can I install a heat pump in a Greenwich house?
Often yes. Houses with workable outdoor space and sensible internal layout are commonly strong local candidates.
Do I need planning permission for a heat pump in Greenwich?
Sometimes not, but parts of Greenwich are more planning-sensitive, so the property should be reviewed before assumptions are made.
How long does a Greenwich heat pump installation take?
Most standard projects take 1-2 days on site, with the full process usually moving from survey to installation in around 2-4 weeks.
Is it worth combining solar with a heat pump in Greenwich?
Yes, especially where the property is a house with usable roof space and a medium-term view on running costs.
