NGED and your Rothwell (North Northamptonshire) connection
Rothwell (North Northamptonshire) is served by National Grid Electricity Distribution (NGED): the town's centre falls inside its East Midlands licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to NGED within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
Larger systems go through G99 instead, applied for before installation. On timing: NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.

Heat pumps and EV charging in Rothwell (North Northamptonshire)
A heat pump in Rothwell (North Northamptonshire)
Heating demand peaks when solar is weakest. In Rothwell (North Northamptonshire), a 12-panel system makes about 230 kWh in December and 240 kWh in January, a fraction of its 790 kWh in July, which is why a heat pump here is costed on its tariff first.
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 Rothwell (North Northamptonshire)
Summer is where a car earns its place. In July, 12 panels in Rothwell (North Northamptonshire) make about 790 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.

Which DNO covers Rothwell (North Northamptonshire), and what does it need from me?
National Grid Electricity Distribution (NGED) covers Rothwell (North Northamptonshire). A home system of up to 3.68kW per phase is notified to NGED within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late.
What happens to the solar I do not use in Rothwell (North Northamptonshire)?
Around £668 a year at 12p per kWh, for the roughly 5,570 kWh a 12-panel system in Rothwell (North Northamptonshire) 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 Rothwell (North Northamptonshire) get in December?
December is the low point: about 230 kWh from a 12-panel system in Rothwell (North Northamptonshire), on PVGIS data, rising to 790 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.
