What Norwich homeowners actually pay
Norwich punches above its weight on solar. Irradiance of around 950 kWh/kWp/yr puts it in the same band as Southampton and Bristol, which surprises homeowners who assume East Anglia is gloomier than the south coast. A 4 kWp install on an Eaton or Thorpe St Andrew semi typically lands at £5,700–£7,300 fully fitted, scaffolded, certified and signed off with UK Power Networks under a G98. Two local quirks matter. The medieval centre sits inside a conservation area where panel visibility from the street can prompt a planning conversation, and the clay pantile roofs common across NR2 and NR3 add a small mounting-labour premium because each pantile needs an individual hook clip rather than a faster batten-rail run.
Conservation areas in Norwich-over-the-Water and Tombland: front-elevation panels usually refused.
Pantile roofs in older properties need pantile-specific mounts; budget extra labour.
Plenty of generous post-war semis in Thorpe St Andrew, Eaton and Hellesdon.
Field notes
Top-quartile UK irradiance — ~3,800 kWh/yr from a 4 kWp system.
DNO is UKPN — G99 approvals typically 4–5 weeks.
Pantile roofs add ~5–8% mounting labour vs. concrete tile.
Frequently asked questions
Is East Anglia really good for solar?
Yes — it consistently ranks just below the south coast for annual sunshine. Generation in NR postcodes is materially better than Manchester, Leeds or Glasgow.
What's the typical payback in Norwich?
8–10 years for a panel-only 4 kWp install at current grid prices. Adding a battery is more about resilience and self-use than shorter payback.
