Heat Pump Installation in Farnham: What You Need to Know
Electromatic M&E Ltd covers Farnham and the GU9/GU10 area for air source heat pump and solar PV installation. Farnham is a historic Surrey market town approximately 28 miles from our Sunbury-on-Thames base (TW16), with a well-preserved Georgian and Victorian town centre alongside extensive semi-detached suburban housing in the surrounding residential areas. 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 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). Farnham’s well-maintained semi-detached and detached suburban housing — which dominates the residential streets away from the historic town centre — is well-positioned for heat pump retrofitting.
Is Your Farnham Home Suitable for a Heat Pump?
Farnham’s suburban housing stock — found throughout the GU9 and GU10 residential areas — includes a significant proportion of 1930s and post-war semi-detached and detached houses. These properties are typically strong heat pump candidates: good cavity wall potential, adequate gardens, and appropriate roof geometry. Many have been improved over the years with insulation already in place.
The historic town centre features Georgian and Victorian buildings, some of which are listed or within conservation areas. These require individual planning assessment, but many full houses in even the conservation-sensitive parts of town can accommodate an ASHP in a rear position that satisfies planning requirements. GU10 covers the rural areas around Farnham, where detached properties often have larger plots ideal for ASHP and solar installations.

Planning Permission in Farnham
Parts of Farnham town centre — particularly the Castle Street area and surrounding Georgian streetscape — are conservation areas where ASHP installation requires careful siting to meet permitted development conditions. Listed buildings require full planning permission. Most suburban GU9 and GU10 residential properties qualify for permitted development under Class G of the GPDO straightforwardly. We carry out all planning and conservation area checks during our free home survey.
The BUS Grant in Farnham: How to Claim £7,500
Your Farnham 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.

ASHP + Solar: The Farnham Combo
Farnham’s GU9 and GU10 properties with south-facing roof slopes benefit from reasonable Surrey solar irradiance. A 4kW solar system generates approximately 3,400–3,700 kWh per year (PVGIS data). The Energy Saving Trust estimates combined ASHP and solar savings of £600–900 per year compared to gas. Rural GU10 properties with larger plots may accommodate 6–8kW solar systems, increasing self-generation significantly. Battery storage is an effective addition for both suburban and rural Farnham properties. Electromatic installs ASHP, solar PV, and battery storage as a coordinated project.
