How Tower Hamlets compares
Tower Hamlets is one of 23 Middlesex towns we track, and it ranks 22nd of 23 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 331,886, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,023 kWh per kWp a year, 2.80 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 £668.
These are starting numbers, not a quote. The calculator below opens on Tower Hamlets' own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Planning applications in Tower Hamlets go to its own council, and the House of Commons Library classes it as a 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.

Who runs the grid in Tower Hamlets
Tower Hamlets sits in UK Power Networks' London licence area, so UK Power Networks 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 UK Power Networks within 28 days of commissioning, with no prior approval.
A bigger inverter or battery output needs a G99 application in advance. 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.

Adding a heat pump or an EV charger in Tower Hamlets
A heat pump in Tower Hamlets
A heat pump does most of its work from November to February. Over those four months, 12 panels in Tower Hamlets make about 1,120 kWh, against 3,060 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Tower Hamlets
From April to September, 68% of a Tower Hamlets roof's yearly output arrives, peaking at about 800 kWh in July on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Tower Hamlets solar questions
What does a solar panel system produce in Tower Hamlets?
Each kWp of panels in Tower Hamlets makes 1,023 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,510 kWh, from about 240 kWh in December up to 800 kWh in July.
What would 12 solar panels cost in Tower Hamlets?
£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 Tower Hamlets differs is output: about 6,510 kWh a year from that system.
Would a system in Tower Hamlets need approval from the network operator?
Tower Hamlets is on UK Power Networks' network (London licence area). Systems up to 3.68kW per phase of inverter output follow G98: UK Power Networks is notified within 28 days of commissioning, with no approval needed first. Anything larger needs a G99 application before installation. 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. Our G98 vs G99 guide explains both routes.
How much would export pay on a system in Tower Hamlets?
It is exported. With typical use and no battery, about 5,570 kWh of the 6,510 kWh a 12-panel system makes in Tower Hamlets goes to the grid, around £668 a year at 12p. A battery keeps more of it for the evening; the export rates table shows what suppliers pay.
Is solar worth it in Tower Hamlets in winter?
It works, but the year is lopsided. 68% of a Tower Hamlets roof's output lands between April and September; the four months from November to February give about 1,120 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Tower Hamlets compares with its neighbours
How the towns nearest Tower Hamlets compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Tower Hamlets |
|---|---|---|
| Tower Hamlets | 1,023 | this town |
| City and County of the City of London | 1,026 | +3 kWh |
| Hackney | 1,025 | +2 kWh |
| Newham | 1,027 | +4 kWh |
| Southwark | 1,029 | +6 kWh |
| Islington | 1,026 | +3 kWh |
| Lewisham | 1,026 | +3 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
