Solar Panels in Greenwich: Costs, Planning, and Local Advice

The Royal Borough of Greenwich sits in south-east London, stretching from the historic riverside at Greenwich town centre out to the suburban expanses of Eltham, Kidbrooke, and Woolwich. Its housing stock ranges from small Victorian terraces near the town centre to large interwar semis and detached properties in Eltham and Shooters Hill. For most Greenwich homeowners, solar is a very practical option.

Solar in Greenwich

The borough's housing divides roughly by era and location. The inner areas — Greenwich town, Blackheath Standard, and parts of Woolwich — have Victorian and Edwardian terraces. Moving east and south, Eltham and Kidbrooke have a mix of interwar semis and post-war housing. The south of the borough (Eltham, Mottingham) has some of the larger detached and semi-detached properties in the area.

Typical system sizes:

• Victorian terraced (Greenwich/Plumstead): 3–4 kWp (7–9 panels)
• Interwar semi-detached (Eltham/Kidbrooke): 4–5 kWp (9–11 panels)
• Detached (Eltham/Mottingham/Shooters Hill): 5–6 kWp

Costs and savings

Installation costs in Greenwich are mid-range for south-east London.

Prices include 0% VAT on supply-and-install, valid to 31 March 2027.

Greenwich property values are more moderate than inner-London boroughs like Wandsworth or Southwark, making solar a proportionally good investment: a 4–8% uplift on a £500,000–650,000 Eltham semi is £20,000–52,000.

Planning in Greenwich

The planning picture in Greenwich is shaped by one notable factor: the Maritime Greenwich World Heritage Site. This designation covers the historic core of the borough — the Old Royal Naval College, the National Maritime Museum, and the immediately surrounding area. The World Heritage Site status imposes restrictions on development that might affect the visual setting of these buildings.

In practice for residential solar: The vast majority of residential properties in Greenwich are far enough from the World Heritage Site core that they are unaffected. But if your property is within or adjacent to the World Heritage Site buffer zone — particularly near Greenwich town centre, the Park, or the hill above — you should check with the Royal Borough of Greenwich's planning team before proceeding. English Heritage guidance suggests that solar on properties within or adjacent to World Heritage Sites should be carefully assessed.

Standard conservation areas: Greenwich town, Blackheath (shared with Lewisham), and parts of Charlton have conservation area designations. The standard rule applies: rear-roof panels are usually still permitted development.

Local schemes

Greenwich Council has distributed Warm Homes Local Grant funding for eligible households. Contact the Royal Borough of Greenwich's sustainability and climate change team for current availability.

The national ECO4 scheme (to December 2026) and the emerging Warm Homes Plan apply to eligible Greenwich households. ECO4 is income-tested and requires qualifying heating measures alongside solar.
