How Oakham compares
Small towns rarely get published solar figures, so here are the numbers for Oakham. It is the only Rutland town we track so far, with county rankings to follow as its neighbours land, a town of 12,290 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,017 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £911 of year one benefit, £247 of it from your own generation and £664 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Oakham'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.
Any planning application in Oakham sits with Rutland, and its official House of Commons Library settlement class is 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.

The network operator for Oakham
Oakham 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 Oakham
A heat pump in Oakham
Heating demand peaks when solar is weakest. In Oakham, 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.
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 Oakham
Oakham's July output, about 790 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).

Oakham solar questions
How much energy would 12 solar panels make in Oakham?
Oakham averages 2.79 peak sun hours a day, which PVGIS turns into 1,017 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,470 kWh, 68% of it between April and September.
Is solar more expensive in Oakham?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Oakham, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,470 kWh a year here, which is what drives payback.
Who is the network operator in Oakham, and do I need a G99 application?
The operator is National Grid Electricity Distribution (NGED). 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. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. Your design call checks which route yours needs.
What could I earn from exporting in Oakham?
On the 12p export scenario, a 12-panel system in Oakham sends about 5,531 kWh a year to the grid, worth around £664. The export rates table compares what each supplier pays.
How does solar perform in Oakham in the winter months?
December is the weakest month in Oakham: about 230 kWh from 12 panels, against 790 kWh in July. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.

PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
