Common Questions
Solar Panel FAQs
How much does solar panel installation cost in London?
A typical 4kW system costs between £6,000 and £9,000 installed. With zero VAT on solar installations and potential export tariffs via the Smart Export Guarantee, payback periods are typically 6–9 years.
Do I need planning permission for solar panels?
In most cases, solar panels are covered by permitted development rights and do not require planning permission. Exceptions include listed buildings, conservation areas, and some flat roofs. Your installer will confirm this during the survey.
What is the BUS grant and am I eligible?
The Boiler Upgrade Scheme (BUS) offers £7,500 off the cost of an air source heat pump. To be eligible, your home must have a valid EPC and existing boiler. Your installer can help you apply.
How long does installation take?
Most domestic solar installations are completed in 1–2 days. Your installer will conduct a survey first to assess roof suitability and system sizing.
Will solar panels work on my roof?
South-facing roofs with minimal shading are ideal, but east and west-facing roofs also generate significant electricity. A surveyor will assess your specific roof during the free survey.
