Heat Pump Installation in Sevenoaks: What You Need to Know
Electromatic M&E Ltd covers Sevenoaks and the TN13/TN14 area for air source heat pump and solar PV installation. Sevenoaks is a premium Kent market town, approximately 30 miles from our Sunbury-on-Thames base, set within or adjacent to Areas of Outstanding Natural Beauty (AONB) and characterised by a high proportion of detached and semi-detached properties. Eligible homeowners may qualify for the Boiler Upgrade Scheme grant of £7,500 towards an ASHP, subject to eligibility.
According to the Energy Saving Trust, a typical UK semi-detached or detached home fitted with an ASHP saves £300–500 per year on heating bills compared to a gas boiler at April 2026 energy prices (electricity 24.5p/kWh, gas 7.4p/kWh). Larger Sevenoaks properties with higher baseline energy consumption may see savings towards the upper end of this range or beyond, making the investment case for a heat pump particularly strong.
Is Your Sevenoaks Home Suitable for a Heat Pump?
Sevenoaks’ housing stock is dominated by detached and semi-detached properties — many of them substantial — which are among the most suitable property types for heat pump installation. Large gardens, well-maintained fabric, and properties that have often already had loft and cavity insulation upgraded make TN13 and TN14 residential areas strong candidates across the board.
The AONB-adjacent character of much of the area means that some properties are in sensitive landscape settings, and planning for any external equipment may require additional care in certain locations. However, for most Sevenoaks residential properties, ASHP installation is straightforward and AONB designation does not in itself prevent permitted development for ASHP units.
Sevenoaks Property Types at a Glance
| Property Type | Heat Pump Suitability | Solar PV Suitability | Notes |
|---|---|---|---|
| Detached house (large) | High | High | Excellent candidate; premium tier; ASHP+Solar+Battery |
| Semi-detached suburban | High | High | Strong candidate; good gardens and roof geometry |
| Victorian/Edwardian villa | Medium-High | High | Insulation check; often substantial properties |
| AONB-adjacent rural property | High | High | Planning check advised; generally permitted development |

Planning Permission in Sevenoaks
Most Sevenoaks residential properties qualify for permitted development rights for ASHP installation under Class G of the General Permitted Development Order. Proximity to AONB does not automatically remove permitted development rights, but properties within or adjacent to conservation areas in Sevenoaks town centre warrant individual checks. Listed buildings require full planning permission for any external equipment. We carry out all necessary planning and conservation area checks during our free home survey.
The BUS Grant in Sevenoaks: How to Claim £7,500
Your Sevenoaks 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 on your behalf as part of every ASHP installation in Sevenoaks.

ASHP + Solar: The Sevenoaks Combo
Sevenoaks’ larger properties with generous south-facing roof areas are well-positioned for combined ASHP and solar PV — and often for larger solar systems of 6–8kW. A 4kW solar system in TN13/TN14 generates approximately 3,400–3,800 kWh per year (PVGIS data), and larger systems proportionally more. The Energy Saving Trust estimates combined ASHP and solar savings of £600–900 per year for average households; larger Sevenoaks properties may see greater absolute savings.
Battery storage is a particularly compelling addition for Sevenoaks homeowners, where the combination of large solar systems and significant evening energy demand makes high self-consumption very achievable. Electromatic installs ASHP, solar PV, and battery storage as a premium integrated project.
Heat Pump Running Costs in Sevenoaks
| 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. Larger Sevenoaks properties will have higher baseline running costs but also greater savings potential.

Frequently Asked Questions — Heat Pumps in Sevenoaks
How much does a heat pump cost in Sevenoaks?
A typical air source heat pump in Sevenoaks costs £10,000–14,000 before the BUS Grant. After the £7,500 government grant (subject to eligibility), most TN13/TN14 homeowners pay £5,000–7,500 all-in for a full ASHP installation. Larger properties may require larger, higher-output systems at additional cost.
Are Sevenoaks’ detached and semi-detached homes suitable for heat pumps?
Yes — they are among the most suitable property types in Kent. Large gardens, good insulation potential, and premium property values make the investment case compelling. We assess everything during the free survey.
Is planning permission needed for a heat pump in Sevenoaks?
For most TN13/TN14 properties, no. ASHP installation qualifies as permitted development. Properties near conservation areas or listed buildings need additional checks. AONB designation alone does not prevent permitted development. We check all this during your free survey.
How long does installation take in Sevenoaks?
A standard installation takes 1–2 days on site. Electromatic M&E Ltd usually installs within 2–4 weeks of survey confirmation. Solar panel installation adds approximately one further day.
Can I get a combined heat pump and solar system in Sevenoaks?
Yes — and larger Sevenoaks properties are particularly well-suited to premium combined installations. 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.
