Solar in London at a glance
The average London home with a 4.4kW south facing system should make about 4,506 kWh a year and save around £684 at today's 26.32p price cap, with 12p a unit for anything sent back to the grid.
Government MCS figures for 2025/26 show homeowners in London paid an average of £2,101 per kW for small systems and £1,759 per kW for 4 to 10kW systems. That is above the England average, mostly because of access, parking and scaffolding costs. Our fixed prices include scaffolding, so there is no separate line for it on your quote.
The sunniest town we cover in London is Romford, at 1,043 kWh per kW. Even in Croydon, at 1,011, a well placed system pays for itself well within the 25 years or more that panels are warranted for. Read whether solar is worth it or try the savings calculator for your own roof.
