How Royal Leamington Spa compares
Among the places we publish figures for, Royal Leamington Spa is one of 19 Warwickshire towns we track, and it ranks joint 4th of 19 for solar yield. It is a medium town in the House of Commons Library classification, with 51,906 residents, and its roofs see 2.74 peak sun hours a day across the year. That drives the standard 12 panel model to 6,360 kWh of generation, of which around 5,423 kWh is exported at 12p for £651 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 Royal Leamington Spa'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 Warwick; nationally, the House of Commons Library classes Royal Leamington Spa 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.

Generation is modelled from PVGIS satellite data for Royal Leamington Spa's own coordinates (52.29205, -1.53121), 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.
NGED and your Royal Leamington Spa connection
Royal Leamington Spa sits in National Grid Electricity Distribution's East Midlands licence area, so NGED is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to NGED within 28 days of commissioning, with no prior approval.
Above that, G99 means applying before the work is booked. 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 Royal Leamington Spa
A heat pump in Royal Leamington Spa
In December, the darkest month here, 12 panels in Royal Leamington Spa make about 220 kWh. That is when a heat pump runs hardest, so its running cost in Royal Leamington Spa comes down to the tariff and the flow temperature rather than the roof.
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 Royal Leamington Spa
Royal Leamington Spa's July output, about 780 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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).

Which DNO covers Royal Leamington Spa, and what does it need from me?
National Grid Electricity Distribution (NGED) covers Royal Leamington Spa. 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 could I earn from exporting in Royal Leamington Spa?
On the 12p export scenario, a 12-panel system in Royal Leamington Spa sends about 5,423 kWh a year to the grid, worth around £651. The export rates table compares what each supplier pays.
How much solar does Royal Leamington Spa get in December?
December is the low point: about 220 kWh from a 12-panel system in Royal Leamington Spa, on PVGIS data, rising to 780 kWh in July. From November to February the same system makes about 1,080 kWh in total, which is why a battery charged off-peak does more of the work in winter.
