How King's Lynn compares
Among the places we publish figures for, King's Lynn is one of 16 Norfolk towns we track, and it ranks 11th of 16 for solar yield. It is a medium town in the House of Commons Library classification, with 48,195 residents, and its roofs see 2.81 peak sun hours a day across the year. That drives the standard 12 panel model to 6,532 kWh of generation, of which around 5,595 kWh is exported at 12p for £671 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on King's Lynn'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.
Planning applications here go through King's Lynn and West Norfolk; nationally, the House of Commons Library classes King's Lynn as a medium 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.

The network operator for King's Lynn
On NESO's licence-area map, King's Lynn is in 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 King's Lynn
A heat pump in King's Lynn
In December, the darkest month here, 12 panels in King's Lynn make about 230 kWh. That is when a heat pump runs hardest, so its running cost in King's Lynn comes down to the tariff and the flow temperature rather than the roof.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in King's Lynn
Summer is where a car earns its place. In May, 12 panels in King's Lynn make about 800 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

King's Lynn solar questions
How much energy would 12 solar panels make in King's Lynn?
King's Lynn averages 2.81 peak sun hours a day, which PVGIS turns into 1,027 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,530 kWh, 68% of it between April and September.
What does a typical solar system cost in King's Lynn?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in King's Lynn, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,530 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in King's Lynn, and do I need a G99 application?
The operator is UK Power Networks. Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted 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. Your design call checks which route yours needs.
What happens to the solar I do not use in King's Lynn?
Around £671 a year at 12p per kWh, for the roughly 5,595 kWh a 12-panel system in King's Lynn exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in King's Lynn in the winter months?
December is the weakest month in King's Lynn: about 230 kWh from 12 panels, against 800 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
