UK households have earned a collective of almost £100m from selling their spare solar power over the past year.
More than 400,000 homes that are on Octopus Energy export tariffs have fed back 825 GWh of power to the grid over the last 12 months. This is equivalent to a gas plant’s annual output.
Even though more people are installing solar for their houses, the public are proceeding with caution as the number of panel fires doubled in 2025.
Rebecca Dibb-Simkin, Chief Product and Marketing Officer at Octopus, said: “Over 400,000 UK households on Octopus tariffs are already generating their own clean energy, and that number just keeps climbing.
“The more we make use of our homegrown green energy sources, the less we rely on fossil fuels, and the more secure our energy system becomes.”
The country’s long periods of heat and sunshine this summer can be partially thanked for the average of £244 per home. Just this year rooftop and ground-mount solar generated a record 14.4% of the country’s electricity demand.
