How Downham Market compares
Small towns rarely get published solar figures, so here are the numbers for Downham Market. It is one of 16 Norfolk towns we track, and it ranks joint 12th of 16 for solar yield, a town of 11,309 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,026 kWh per kWp a year, 2.81 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £918 of year one benefit, £247 of it from your own generation and £671 from export at 12p.
These are starting numbers, not a quote. The calculator below opens on Downham Market'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.
Planning applications here go through King's Lynn and West Norfolk; nationally, the House of Commons Library classes Downham Market 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.

Generation is modelled from PVGIS satellite data for Downham Market's own coordinates (52.60333, 0.37861), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
UK Power Networks and your Downham Market connection
UK Power Networks owns and runs the local electricity network in Downham Market, 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.
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.

Adding a heat pump or an EV charger in Downham Market
A heat pump in Downham Market
Heating demand peaks when solar is weakest. In Downham Market, a 12-panel system makes about 230 kWh in December and 240 kWh in January, a fraction of its 800 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 Downham Market
Downham Market's July output, about 800 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.
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).

Which DNO covers Downham Market, and what does it need from me?
UK Power Networks covers Downham Market. A home system of up to 3.68kW per phase is notified to UK Power Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What could I earn from exporting in Downham Market?
On the 12p export scenario, a 12-panel system in Downham Market sends about 5,589 kWh a year to the grid, worth around £671. The export rates table compares what each supplier pays.
How much solar does Downham Market get in December?
December is the low point: about 230 kWh from a 12-panel system in Downham Market, on PVGIS data, rising to 800 kWh in July. From November to February the same system makes about 1,120 kWh in total, which is why a battery charged off-peak does more of the work in winter.
