What Oxford homeowners actually pay
Oxford has some of the best irradiance figures of any English city we cover (~945 kWh/kWp/yr) and a strong installer market thanks to the M40 corridor. The wrinkle is heritage: large parts of central Oxford and North Oxford sit in conservation areas, so most installs go on rear elevations. A 4 kWp install on a Headington or Cowley semi typically lands £6,000–£7,800, with around 3,780 kWh per year and a payback of 8–10 years.

Frequently asked questions
Can I fit panels on a North Oxford Victorian?
Yes on rear elevations as permitted development. Front-facing panels in conservation areas usually need a planning application. Listed buildings always need Listed Building Consent regardless of roof side.
What system size suits a typical Oxford terrace?
3–4 kWp on most Cowley, Headington and Marston terraces. Larger semis and detached homes in Summertown or Wolvercote often fit 5–6 kWp with battery.
