The network operator for Bishop's Stortford
On NESO's licence-area map, Bishop's Stortford is in East England, which UK Power Networks operates. That makes UK Power Networks the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to UK Power Networks within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: 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 Bishop's Stortford
A heat pump in Bishop's Stortford
In December, the darkest month here, 12 panels in Bishop's Stortford make about 230 kWh. That is when a heat pump runs hardest, so its running cost in Bishop's Stortford comes down to the tariff and the flow temperature rather than the roof.
In England, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Bishop's Stortford
Summer is where a car earns its place. In July, 12 panels in Bishop's Stortford make about 800 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
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.

Common questions about solar in Bishop's Stortford
How much electricity do solar panels make in Bishop's Stortford?
About 6,580 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Bishop's Stortford: 1,035 kWh per kWp, or 2.84 peak sun hours a day on average. July is the strongest month, at about 800 kWh.
What does a typical solar system cost in Bishop's Stortford?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Bishop's Stortford, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,580 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Bishop's Stortford, and what does it need from me?
UK Power Networks covers Bishop's Stortford. 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 happens to the solar I do not use in Bishop's Stortford?
Around £678 a year at 12p per kWh, for the roughly 5,646 kWh a 12-panel system in Bishop's Stortford exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Bishop's Stortford get in December?
December is the low point: about 230 kWh from a 12-panel system in Bishop's Stortford, on PVGIS data, rising to 800 kWh in July. From November to February the same system makes about 1,110 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Bishop's Stortford 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 Bishop's Stortford |
|---|---|---|
| Bishop's Stortford | 1,035 | this town |
| Stansted Mountfitchet | 1,028 | −7 kWh |
| Sawbridgeworth | 1,034 | −1 kWh |
| Harlow | 1,032 | −3 kWh |
| Great Dunmow | 1,055 | +20 kWh |
| Ware | 1,018 | −17 kWh |
| Buntingford | 1,026 | −9 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.
