How Warlingham compares
Small towns rarely get published solar figures, so here are the numbers for Warlingham. It is one of 47 Surrey towns we track, and it ranks joint 41st of 47 for solar yield, a town of 8,880 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,017 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £911 of year one benefit, £247 of it from your own generation and £664 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Warlingham's 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.
Warlingham sits within Tandridge, its local planning authority, and the House of Commons Library classes it as a small 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 Warlingham network
UK Power Networks owns and runs the local electricity network in Warlingham, as part of its South 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.

Adding a heat pump or an EV charger in Warlingham
A heat pump in Warlingham
Solar and a heat pump pull in opposite directions through the year: Warlingham's roofs make 1,080 kWh from November to February on a 12-panel system, and 3,070 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 Warlingham
A 12-panel roof in Warlingham makes about 800 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.
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).

Warlingham solar questions
What could a roof in Warlingham generate?
PVGIS puts a roof in Warlingham at 1,017 kWh per kWp a year, 2.79 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,470 kWh a year, most of it between April and September.
How much are solar panels in Warlingham?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Warlingham before a battery. What Warlingham changes is the return, about 6,470 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Warlingham?
Usually not in advance. UK Power Networks, the network operator for Warlingham, 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 Warlingham?
With typical use and no battery, a 12-panel system in Warlingham exports about 5,531 kWh a year. At 12p per kWh that is roughly £664; 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 Warlingham?
Yes, at a lower level. PVGIS gives Warlingham 36 kWh per kWp in December and 37.3 in January, so a 12-panel system makes about 230 kWh and 240 kWh in those months, against 800 kWh in July. Winter output mostly covers daytime use rather than exporting.

East, west or south facing: what your roof direction really costs you
An east west split gives up about a fifth of the annual total, and can still be worth more than south.

Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
