-
269,000 solar installations completed in 2025 – the highest
total ever recorded in a calendar
year and 37 per cent larger than the year
before.
-
23,000 new solar installations in April 2026, with more than
half installed on homes – showing
households are turning to homegrown energy following the
war in Iran.
-
Nine of the ten strongest months for solar deployment on
record have happened within the last year.
Households across the UK continue to embrace solar
power as the government accelerates its clean power mission to
reduce Britain's exposure to volatile fossil fuel
markets following the outbreak of the war in
Iran.
New government data published today shows that 2025 was the
strongest year on record for solar deployment, with 269,000
installations completed across the UK. Around 255,000
of these were rooftop solar - meaning at least 95 per
cent of all new solar was installed on
homes, businesses and other buildings. This
equates to a new rooftop solar installation every two minutes
throughout 2025.
April 2026 figures published today also confirm that nine of the
ten best-performing months ever recorded have occurred in the
past year, with nearly 23,000 new installations in the last month
alone - and more than 1 in 2 of those being rooftop
solar on homes, showing households are increasingly choosing
to generate their own power.
The milestone follows the UK surpassing 2 million total solar
installations for the first time in March 2026, across
homes, communities and solar farms nationwide. It
also comes as new annual figures from the
government today show that the cost
of acquiring and installing solar
PV has deceased by up to 9 per cent.
The surge reflects growing government investment in solar power
to deliver clean energy and help lower bills, with rooftop solar
saving families up to £480 a month. This includes:
-
Consenting Springwell Solar Farm, the largest
power-producing solar farm in UK history.
-
Driving forward with the rollout of “plug-in” solar panels
(low-cost panels that families can put on their balconies or
outdoor space) to be available in shops within months
and save people money on their bills.
-
Ensuring solar panels are fitted on new homes in
England as standard.
Energy Secretary said:
As we face a second fossil fuel crisis in five
years, Britain is taking back control of their energy
by generating more clean power than
ever before. Record-breaking solar growth means greater
energy security, lower exposure to volatile fossil fuel markets
which we can't control.
This is what our clean power mission looks like: backing
homegrown energy, giving people more control over their
bills, and building a stronger, more resilient energy system for
the future.
Businesses and public services are also embracing Britain's solar
revolution - cutting costs and strengthening energy
security.
Numatic International, the maker of Henry the Hoover, has
launched a new solar park expected to supply around 20% of
its Somerset factory's electricity demand.
Mid Cheshire Hospitals NHS Foundation Trust has installed rooftop
solar expected to cut bills by around £9,500 a year, while Wren
Kitchens is building what is set to become the UK's largest
factory rooftop solar array.
These installations build on the success of Great British
Energy's solar scheme, with a further 100 schools and colleges
set to receive rooftop solar this year.
