How Leatherhead compares
Small towns rarely get published solar figures, so here are the numbers for Leatherhead. It is one of 47 Surrey towns we track, and it ranks joint 10th of 47 for solar yield, a town of 11,932 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,030 kWh per kWp a year, 2.82 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £921 of year one benefit, £247 of it from your own generation and £674 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Leatherhead's own yield, and prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.
Any planning application in Leatherhead sits with Mole Valley, and its official House of Commons Library settlement class is small town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

Generation is modelled from PVGIS satellite data for Leatherhead's own coordinates (51.29578, -0.32486), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
The network operator for Leatherhead
On NESO's licence-area map, Leatherhead is in South East England, which UK Power Networks operates. That makes UK Power Networks the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to UK Power Networks within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.

Heat pumps and EV charging in Leatherhead
A heat pump in Leatherhead
Heating demand peaks when solar is weakest. In Leatherhead, a 12-panel system makes about 230 kWh in December and 250 kWh in January, a fraction of its 810 kWh in July, which is why a heat pump here is costed on its tariff first.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Leatherhead
Summer is where a car earns its place. In July, 12 panels in Leatherhead make about 810 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Solar in Leatherhead: your questions answered
How much electricity do solar panels make in Leatherhead?
About 6,550 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Leatherhead: 1,030 kWh per kWp, or 2.82 peak sun hours a day on average. July is the strongest month, at about 810 kWh.
What does a typical solar system cost in Leatherhead?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Leatherhead, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,550 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Leatherhead, and what does it need from me?
UK Power Networks covers Leatherhead. A home system of up to 3.68kW per phase is notified to UK Power Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds UK Power Networks as it does every network operator.
What happens to the solar I do not use in Leatherhead?
Around £674 a year at 12p per kWh, for the roughly 5,614 kWh a 12-panel system in Leatherhead exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Leatherhead get in December?
December is the low point: about 230 kWh from a 12-panel system in Leatherhead, on PVGIS data, rising to 810 kWh in July. From November to February the same system makes about 1,110 kWh in total, which is why a battery charged off-peak does more of the work in winter.

Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
