What the planet gets
There's no net metering in the UK. You save the retail rate on power you use as it's generated, and earn the Smart Export Guarantee (SEG) rate on what you export.

How East of England compares to the UK average
UK electricity prices are broadly uniform under the price cap, so sun is the regional variable that moves your payback.

Solar cost & savings by system size in East of England
Computed with East of England's generation (~2.85 kWh/kW/day), a ~27p/kWh import rate, ~50% self-consumption, and an average SEG export rate, 0% VAT included.
| System size | Installed cost (0% VAT) | Generation/yr | Annual savings | Payback |
|---|---|---|---|---|
| 3kW | ~£5,100 | ~3,078 kWh | ~£616 | ~8.3 yrs |
| 4kW | ~£6,800 | ~4,104 kWh | ~£821 | ~8.3 yrs |
| 5kW | ~£8,500 | ~5,130 kWh | ~£1,026 | ~8.3 yrs |
| 6kW | ~£10,200 | ~6,156 kWh | ~£1,231 | ~8.3 yrs |

How solar pays in East of England
There's no net metering in the UK, so your system pays you two ways: you save your import rate (~27p/kWh) on every unit you use as it's generated, and you earn your Smart Export Guarantee rate on everything you send back to the grid. Using more of your own power, daytime appliance use, or a battery, is worth more than exporting it, especially on lower SEG tariffs.
Generation figures are regional averages; your roof's pitch, orientation, and shading will move them.
East of England solar FAQs
Are solar panels worth it in East of England?
For a typical £90/month bill, we estimate a system in East of England pays for itself in about 8.3 years, then generates largely free power for another 15+ years. Norfolk, Suffolk, and Essex are dry and bright, giving well-above-average generation.
How much do solar panels cost in East of England?
Prices don't vary much by region, expect roughly £1,700 per kW installed with 0% VAT already applied, so a 4kW system runs about £6,800. What varies regionally is generation: in East of England each kW produces around 1040 kWh a year.
How much electricity will solar generate in East of England?
Around 2.85 kWh per kW per day averaged across the year, so a 4kW system produces roughly 4,161 kWh annually. Summer output is several times winter output, and orientation and shading move the total.
Do I get paid for exported power?
Yes, through the Smart Export Guarantee (SEG). Rates vary hugely by supplier, from about 6p to 25p/kWh, and the tariff you pick matters as much as your region's sun. There's no net metering in the UK: you save ~27p on each unit you use yourself but earn only your SEG rate on exports.
Does East of England get enough sun for solar?
Yes. Norfolk, Suffolk, and Essex are dry and bright, giving well-above-average generation. Even the cloudiest UK regions generate enough for a workable return because grid electricity is expensive, the maths runs on the ~27p/kWh you avoid buying, not on wall-to-wall sunshine.
