How Great Dunmow compares
Small towns rarely get published solar figures, so here are the numbers for Great Dunmow. It is one of 46 Essex towns we track, and it ranks joint 28th of 46 for solar yield, a town of 10,764 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,055 kWh per kWp a year, 2.89 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £940 of year one benefit, £247 of it from your own generation and £693 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Great Dunmow'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.
Uttlesford is the planning authority covering Great Dunmow, which the House of Commons Library classes 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 Great Dunmow's own coordinates (51.8732, 0.35956), 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.
Who runs the grid in Great Dunmow
UK Power Networks owns and runs the local electricity network in Great Dunmow, 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.

Heat pumps and EV charging in Great Dunmow
A heat pump in Great Dunmow
A heat pump does most of its work from November to February. Over those four months, 12 panels in Great Dunmow make about 1,150 kWh, against 3,140 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 Great Dunmow
A 12-panel roof in Great Dunmow makes about 810 kWh in June. 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.
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.

Great Dunmow solar questions
What does a solar panel system produce in Great Dunmow?
Each kWp of panels in Great Dunmow makes 1,055 kWh a year on PVGIS figures, so a typical 12-panel system produces around 6,710 kWh, from about 240 kWh in December up to 810 kWh in June.
What would 12 solar panels cost in Great Dunmow?
£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 Great Dunmow differs is output: about 6,710 kWh a year from that system.
Would a system in Great Dunmow need approval from the network operator?
Great Dunmow 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 Great Dunmow?
It is exported. With typical use and no battery, about 5,773 kWh of the 6,710 kWh a 12-panel system makes in Great Dunmow goes to the grid, around £693 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 Great Dunmow in winter?
It works, but the year is lopsided. 68% of a Great Dunmow roof's output lands between April and September; the four months from November to February give about 1,150 kWh on a 12-panel system. Payback is worked out on the whole year, not the winter.
How Great Dunmow compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Great Dunmow.

Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
