How Billericay compares
Among the places we publish figures for, Billericay is one of 46 Essex towns we track, and it ranks joint 22nd of 46 for solar yield. It is a medium town in the House of Commons Library classification, with 34,191 residents, and its roofs see 2.91 peak sun hours a day across the year. That drives the standard 12 panel model to 6,754 kWh of generation, of which around 5,818 kWh is exported at 12p for £698 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 Billericay'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.
Billericay sits within Basildon, 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 Billericay network
UK Power Networks owns and runs the local electricity network in Billericay, 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.
Anything bigger is a G99 case and is applied for 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.

Heat pumps and EV charging in Billericay
A heat pump in Billericay
Solar and a heat pump pull in opposite directions through the year: Billericay's roofs make 1,170 kWh from November to February on a 12-panel system, and 3,170 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Billericay
From April to September, 68% of a Billericay 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.
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 Billericay: your questions answered
What could a roof in Billericay generate?
PVGIS puts a roof in Billericay at 1,062 kWh per kWp a year, 2.91 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,750 kWh a year, most of it between April and September.
How much are solar panels in Billericay?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Billericay before a battery. What Billericay changes is the return, about 6,750 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Billericay?
Usually not in advance. UK Power Networks, the network operator for Billericay, 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. 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. "See our DNO explainer.
How much can I earn from exporting solar in Billericay?
With typical use and no battery, a 12-panel system in Billericay exports about 5,818 kWh a year. At 12p per kWh that is roughly £698; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Billericay?
Yes, at a lower level. PVGIS gives Billericay 38.4 kWh per kWp in December and 40.9 in January, so a 12-panel system makes about 240 kWh and 260 kWh in those months, against 820 kWh in July. Winter output mostly covers daytime use rather than exporting.

Reading for Billericay homeowners
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 →How an air source heat pump actually works
It moves heat rather than making it. The cycle, the efficiency numbers and the trade-offs.
Read the guide →The price cap explained, and what it does to solar payback
The cap limits unit rates, not bills. That changes what solar payback means.
Read the guide →G98 or G99: which one applies, what the application involves, and how long it takes
The G98 line sits at 3.68kW per phase. Above it, your network operator has to say yes first.
