How Islington compares
Islington is one of 23 Middlesex towns we track, and it ranks joint 5th of 23 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 223,560, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,026 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons, and on the 12p scenario about £247 of the year one benefit comes from solar you use yourself, with export income adding £671.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Islington'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.
Islington is its own local planning authority area, and its House of Commons Library settlement class is core city.
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.

UK Power Networks and your Islington connection
Islington is served by UK Power Networks: the town's centre falls inside its London licence area on NESO's boundary map.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: UK Power Networks is notified within 28 days of commissioning and nothing has to be approved first.
Above that, G99 means applying before the work is booked. 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 UK Power Networks as it does every network operator.

Heat pumps and EV charging in Islington
A heat pump in Islington
Heating demand peaks when solar is weakest. In Islington, a 12-panel system makes about 240 kWh in December and 260 kWh in January, a fraction of its 790 kWh in July, which is why a heat pump here is costed on its tariff first.
Grant support in England comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Islington
Islington'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.
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 Islington: your questions answered
How much energy would 12 solar panels make in Islington?
Islington averages 2.81 peak sun hours a day, which PVGIS turns into 1,026 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 6,530 kWh, 67% of it between April and September.
Is solar more expensive in Islington?
Prices on this site are the same everywhere: £1,000 per kWp installed, which puts a 12-panel system at £6,360 in Islington, and a Duracell Dura16 installed with solar at £4,450 on top. The local part is generation, about 6,530 kWh a year here, which is what drives payback.
Who is the network operator in Islington, and do I need a G99 application?
The operator is UK Power Networks. 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. 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 UK Power Networks as it does every network operator. Your design call checks which route yours needs.
What could I earn from exporting in Islington?
On the 12p export scenario, a 12-panel system in Islington sends about 5,589 kWh a year to the grid, worth around £671. The export rates table compares what each supplier pays.
How does solar perform in Islington in the winter months?
December is the weakest month in Islington: about 240 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.
How Islington compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Islington.
| Town | kWh per kWp a year | vs Islington |
|---|---|---|
| Islington | 1,026 | this town |
| Hackney | 1,025 | −1 kWh |
| Camden | 1,026 | level |
| City and County of the City of London | 1,026 | level |
| Haringey | 1,024 | −2 kWh |
| City of Westminster | 1,026 | level |
| Tower Hamlets | 1,023 | −3 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.
