How Havering compares
Havering is one of 46 Essex towns we track, and it ranks 34th of 46 for solar yield. The House of Commons Library settlement classification puts it in the core city class, with a population of 273,656, which makes it one of the largest places we publish figures for. Scale changes nothing about the physics: PVGIS gives a roof here 1,045 kWh per kWp a year, 2.86 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 £685.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Havering's own yield.
Planning applications in Havering 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 Havering
UK Power Networks owns and runs the local electricity network in Havering, as part of its East England licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means UK Power Networks is notified within 28 days of switch-on rather than asked beforehand.
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.

Beyond the panels: heating and car charging in Havering
A heat pump in Havering
A heat pump does most of its work from November to February. Over those four months, 12 panels in Havering make about 1,140 kWh, against 3,130 kWh from May to August, so winter heating runs mostly on grid electricity and the tariff matters more than the roof.
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 Havering
From April to September, 68% of a Havering roof's yearly output arrives, peaking at about 820 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.
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).

Solar in Havering: your questions answered
What does a solar panel system produce in Havering?
Each kWp of panels in Havering makes 1,045 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,650 kWh, from about 240 kWh in December up to 820 kWh in July.
What would 12 solar panels cost in Havering?
£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 Havering differs is output: about 6,650 kWh a year from that system.
Would a system in Havering need approval from the network operator?
Havering is on UK Power Networks' network (East England 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 Havering?
It is exported. With typical use and no battery, about 5,710 kWh of the 6,650 kWh a 12-panel system makes in Havering goes to the grid, around £685 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 Havering in winter?
It works, but the year is lopsided. 68% of a Havering roof's output lands between April and September; the four months from November to February give about 1,140 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Havering compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Havering |
|---|---|---|
| Havering | 1,045 | this town |
| Barking and Dagenham | 1,040 | −5 kWh |
| Aveley | 1,049 | +4 kWh |
| South Ockendon | 1,050 | +5 kWh |
| Brentwood | 1,049 | +4 kWh |
| Redbridge | 1,035 | −10 kWh |
| Chigwell | 1,032 | −13 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.
