Connecting solar to the Tadworth and Epsom Downs network
Tadworth and Epsom Downs is served by UK Power Networks: the town's centre falls inside its South East England licence area on NESO's boundary map.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: UK Power Networks is notified within 28 days of commissioning and nothing has to be approved first.
Anything bigger is a G99 case and is applied for first. 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 Tadworth and Epsom Downs
A heat pump in Tadworth and Epsom Downs
Solar and a heat pump pull in opposite directions through the year: Tadworth and Epsom Downs' roofs make 1,090 kWh from November to February on a 12-panel system, and 3,070 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Tadworth and Epsom Downs
From April to September, 68% of a Tadworth and Epsom Downs roof's yearly output arrives, peaking at about 800 kWh in July on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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).

What could a roof in Tadworth and Epsom Downs generate?
PVGIS puts a roof in Tadworth and Epsom Downs at 1,019 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,480 kWh a year, most of it between April and September.
How much are solar panels in Tadworth and Epsom Downs?

Do I need permission from the DNO for solar in Tadworth and Epsom Downs?
Usually not in advance. UK Power Networks, the network operator for Tadworth and Epsom Downs, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval first. 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. "See our DNO explainer.
How much can I earn from exporting solar in Tadworth and Epsom Downs?
With typical use and no battery, a 12-panel system in Tadworth and Epsom Downs exports about 5,544 kWh a year. At 12p per kWh that is roughly £665; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Tadworth and Epsom Downs?
Yes, at a lower level. PVGIS gives Tadworth and Epsom Downs 36.2 kWh per kWp in December and 38.1 in January, so a 12-panel system makes about 230 kWh and 240 kWh in those months, against 800 kWh in July. Winter output mostly covers daytime use rather than exporting.
