How Bletchley compares
Among the places we publish figures for, Bletchley is one of 19 Buckinghamshire towns we track, and it ranks joint 8th of 19 for solar yield. It is a medium town in the House of Commons Library classification, with 47,270 residents, and its roofs see 2.77 peak sun hours a day across the year. That drives the standard 12 panel model to 6,436 kWh of generation, of which around 5,500 kWh is exported at 12p for £660 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 Bletchley'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.
Bletchley sits within Milton Keynes, its local planning authority, and the House of Commons Library classes it 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.

Connecting solar to the Bletchley network
Bletchley 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.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, NGED only has to be told within 28 days after the system is commissioned.
A bigger inverter or battery output needs a G99 application in advance. 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 Bletchley
A heat pump in Bletchley
Solar and a heat pump pull in opposite directions through the year: Bletchley's roofs make 1,100 kWh from November to February on a 12-panel system, and 3,030 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 Bletchley
A 12-panel roof in Bletchley makes about 790 kWh in July. A typical home uses around 70 kWh of that in daylight (the calculator's typical-use settings), which leaves most of the month's output for an EV or for export.
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.

Solar in Bletchley: your questions answered
What could a roof in Bletchley generate?
PVGIS puts a roof in Bletchley at 1,012 kWh per kWp a year, 2.77 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,440 kWh a year, most of it between April and September.
What would 12 solar panels cost in Bletchley?
£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 Bletchley differs is output: about 6,440 kWh a year from that system.
Do I need permission from the DNO for solar in Bletchley?
Usually not in advance. NGED, the network operator for Bletchley, 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. NGED's guaranteed standards give 45 working days for a low voltage generation quotation, with £80 paid for each working day late. "See our DNO explainer.
How much would export pay on a system in Bletchley?
It is exported. With typical use and no battery, about 5,500 kWh of the 6,440 kWh a 12-panel system makes in Bletchley goes to the grid, around £660 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 Bletchley?
Yes, at a lower level. PVGIS gives Bletchley 35.9 kWh per kWp in December and 38.7 in January, so a 12-panel system makes about 230 kWh and 250 kWh in those months, against 790 kWh in July. Winter output mostly covers daytime use rather than exporting.
How Bletchley compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Bletchley.
| Town | kWh per kWp a year | vs Bletchley |
|---|---|---|
| Bletchley | 1,012 | this town |
| Milton Keynes | 1,014 | +2 kWh |
| Newport Pagnell | 1,010 | −2 kWh |
| Leighton Buzzard | 1,012 | level |
| Cranfield | 1,019 | +7 kWh |
| Flitwick | 1,023 | +11 kWh |
| Buckingham | 1,014 | +2 kWh |
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.

Guides worth reading before your call
Sourced, dated and written by us. The same ground we cover on your free call.
What a solar service costs, and how often you actually need one
MCS advises a contractor visit at year 10 on a privately owned home. Most plans sell one a year.
Read the guide →Does a standalone battery actually pay back?
No panels means one job: buy cheap, use later. The tariff decides whether it pays.
Read the guide →Three phase and EV charging: what actually changes
Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
Read the guide →The Boiler Upgrade Scheme, explained
A fixed amount, claimed on your behalf by our installation teams, with a real deadline on the £9,000 version.
Read the guide →What the Smart Export Guarantee actually is
The scheme obliges suppliers to pay above zero, and leaves the rate to them.
