London solar panel questions.
How much do solar panels cost in London?
A 4 kWp system in London typically costs £6,800–£10,000 fully installed (slightly higher than the UK average due to scaffolding access in dense streets). 0% VAT applies until 31 March 2027. Larger 6 kWp systems with battery typically run £11,000–£15,000.
Do solar panels work in London?
Very well. London receives roughly 1,500 sun hours per year — better than Manchester or Newcastle. A 4 kWp system generates around 3,600–3,800 kWh annually. London's high grid electricity prices also push payback periods shorter than the UK average.
Do I need planning permission?
For most London homes, solar PV is permitted development. Conservation areas (most of central London, Hampstead, Dulwich, Greenwich) and listed buildings need a planning check, which your installer handles before quoting.
