Heat Pump Installation in Kennington: What You Need to Know
Electromatic M&E Ltd covers Kennington (SE11), approximately 15 miles from our Sunbury-on-Thames base, installing air source heat pumps and solar PV systems across this historically rich south London neighbourhood. The BUS Grant of £7,500 (subject to eligibility) can significantly reduce the upfront cost of switching from gas for Kennington homeowners. Kennington’s housing stock is predominantly Victorian terraces and some conservation-sensitive streets, which means insulation quality and careful siting are essential considerations at survey stage.
According to the Energy Saving Trust, an average UK semi-detached home fitted with an air source heat pump saves between £300 and £500 per year on heating bills compared to a gas boiler, based on April 2026 Ofgem price cap energy prices (electricity at 24.5p/kWh, gas at 7.4p/kWh).
Is Your Kennington Home Suitable for a Heat Pump?
Most Kennington homes are Victorian terraces, built between roughly 1860 and 1910, and these properties can work well with a modern air source heat pump provided a few conditions are met. The key variables are insulation quality, radiator sizing, and available external space for the ASHP unit — all of which Electromatic assesses free of charge during the home survey.
Victorian terraces in SE11 often have solid brick walls rather than cavity walls, which means solid wall insulation (internal or external) is the main insulation upgrade route. However, Nesta research published in 2024 found that over 80% of UK homes — including many solid-wall terraces — can operate a heat pump at an acceptable efficiency level once the system is correctly sized and the flow temperatures are optimised. Many Kennington terraces have already had loft insulation installed, which is a significant step towards heat pump readiness.
Parts of Kennington border conservation areas, particularly streets close to Kennington Park and the Kennington Conservation Area itself. In these locations, the siting of the ASHP outdoor unit needs careful consideration to ensure the installation does not face a public highway — a condition of permitted development under Class G of the General Permitted Development Order.
Kennington Property Types at a Glance
| Property Type | Heat Pump Suitability | Solar PV Suitability | Notes |
|---|---|---|---|
| Victorian terrace (solid wall) | Medium | Medium | Insulation check needed; flow temp optimisation important; many suitable |
| Victorian terrace (with modern insulation) | High | Medium | Strong candidate; radiator sizing to be confirmed at survey |
| Converted flat | Low | Low–Medium | ASHP generally not suitable; flat roof solar possible if roof access confirmed |
| End-of-terrace | High | Medium–High | More external wall options; often better for unit siting |

Planning Permission in Kennington
Most Kennington homes qualify for permitted development rights when it comes to ASHP installation, which means no formal planning application is required. However, parts of SE11 fall within or adjacent to conservation areas, including the Kennington Conservation Area and areas close to the Oval and Lambeth Road. In these settings, the outdoor ASHP unit must not be installed on a wall or roof that faces a highway, and a noise assessment in line with MIS 3005 standards is standard practice.
Electromatic carries out all necessary siting checks and noise assessments as part of the free home survey. For the majority of Kennington properties — particularly those set back from main roads — permitted development rights apply and the installation can proceed without additional planning steps. If your property is listed, full planning permission is required regardless of location.
The BUS Grant in Kennington: How to Claim £7,500
Your Kennington home may qualify for the Boiler Upgrade Scheme (BUS) grant of £7,500 towards an air source heat pump, subject to eligibility. To qualify, your property must have a valid EPC with no outstanding recommendations for loft or cavity wall insulation. Electromatic handles the BUS Grant application as part of every ASHP installation — you do not need to apply yourself. Ofgem administers the scheme, and the grant is paid directly to the installer, reducing your upfront cost accordingly.
For Victorian terraces in SE11, the EPC check is particularly important. If the EPC recommends solid wall insulation but this has not yet been installed, the property may not qualify until that work is completed. Our survey team will review this with you before any commitment is made.

ASHP + Solar: The Kennington Combo
Combining an air source heat pump with solar PV is an increasingly popular choice among Kennington homeowners who want to address both heating and electricity costs in a single project. In SE11, a south-facing 4kW solar system generates approximately 3,400–3,800 kWh per year (based on PVGIS London irradiance data), which can meaningfully offset the electricity consumed by the heat pump during daylight hours.
According to the Energy Saving Trust, households combining ASHP with solar PV typically save between £600 and £900 per year on energy bills compared to a gas boiler and grid electricity alone. Battery storage is an optional add-on that allows surplus solar generation during the day to power the heat pump in the evening — particularly useful for households with high evening heating demand in winter. Electromatic installs ASHP and solar as a combined package, meaning one project, one contractor, and a coherent system design.
Heat Pump Running Costs in Kennington
| 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.

Frequently Asked Questions — Heat Pumps in Kennington
How much does a heat pump cost in Kennington?
A typical air source heat pump in Kennington costs £10,000–14,000 before the BUS Grant. After the £7,500 government grant (subject to eligibility), most Kennington homeowners pay £5,000–7,500 all-in for a full ASHP installation including labour, materials, and commissioning.
Do heat pumps work in Kennington’s Victorian terraces?
Many do, particularly those that have had loft insulation installed and are not severely under-insulated at wall level. Radiator upgrades may be needed in some rooms to work at the lower flow temperatures heat pumps prefer. We assess this as part of our free survey, so there are no surprises.
Is planning permission needed for a heat pump in Kennington?
In most of Kennington, heat pump installation falls under permitted development rights — no planning application is needed. Exceptions apply to listed buildings and properties within designated conservation areas. We check this during your free survey and advise accordingly.
How long does installation take in Kennington?
A heat pump installation typically takes 1–2 days for a standard property. Electromatic M&E Ltd usually installs within 2–4 weeks of survey confirmation — significantly faster than most national installers. Solar panel installation adds a further day.
Can I get a combined heat pump and solar panels in Kennington?
Yes — and it is often the best value option. Electromatic installs ASHP and solar PV as a combined package, meaning one contractor, one project, and a coherent system design. A combined ASHP + 4kW solar system typically costs £17,000–19,000 before grants, with the BUS Grant (£7,500, subject to eligibility) reducing the heat pump element significantly.
