How Berwick-upon-Tweed compares
Small towns rarely get published solar figures, so here are the numbers for Berwick-upon-Tweed. It is one of 18 Northumberland towns we track, and it ranks 10th of 18 for solar yield, a town of 13,301 people in the House of Commons Library settlement data. PVGIS gives its roofs 958 kWh per kWp a year, 2.62 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £866 of year one benefit, £247 of it from your own generation and £619 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Berwick-upon-Tweed'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.
Berwick-upon-Tweed sits within Northumberland, its local planning authority, and the House of Commons Library classes it as a 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.

Connecting solar to the Berwick-upon-Tweed network
On NESO's licence-area map, Berwick-upon-Tweed is in South and Central Scotland, which SP Energy Networks operates. That makes SP Energy 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 SP Energy Networks within 28 days of commissioning, with no prior approval.
A bigger inverter or battery output needs a G99 application in advance. 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 SP Energy Networks as it does every network operator.

Heat pumps and EV charging in Berwick-upon-Tweed
A heat pump in Berwick-upon-Tweed
Solar and a heat pump pull in opposite directions through the year: Berwick-upon-Tweed's roofs make 930 kWh from November to February on a 12-panel system, and 2,970 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Berwick-upon-Tweed
From April to September, 70% of a Berwick-upon-Tweed roof's yearly output arrives, peaking at about 820 kWh in May 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.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Berwick-upon-Tweed solar questions
What could a roof in Berwick-upon-Tweed generate?
PVGIS puts a roof in Berwick-upon-Tweed at 958 kWh per kWp a year, 2.62 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,090 kWh a year, most of it between April and September.
What would 12 solar panels cost in Berwick-upon-Tweed?
£6,360 for 12 panels (6.36 kWp), the same as in every other place we cover, because solar is priced at £1,000 per kWp installed rather than by area. A battery adds its own installed price on top. Where Berwick-upon-Tweed differs is output: about 6,090 kWh a year from that system.
Do I need permission from the DNO for solar in Berwick-upon-Tweed?
Usually not in advance. SP Energy Networks, the network operator for Berwick-upon-Tweed, 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 SP Energy Networks as it does every network operator. "See our DNO explainer.
How much would export pay on a system in Berwick-upon-Tweed?
It is exported. With typical use and no battery, about 5,156 kWh of the 6,090 kWh a 12-panel system makes in Berwick-upon-Tweed goes to the grid, around £619 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Do solar panels work in winter in Berwick-upon-Tweed?
Yes, at a lower level. PVGIS gives Berwick-upon-Tweed 25.9 kWh per kWp in December and 31.5 in January, so a 12-panel system makes about 160 kWh and 200 kWh in those months, against 820 kWh in May. Winter output mostly covers daytime use rather than exporting.
