Aldi is investing £17.5 million to install solar panels at more than 200 of its UK stores, part of a major expansion of its renewable energy programme. The supermarket chain plans to carry out the installations between 2027 and 2031, taking its total investment in solar power to around £26 million.
The new systems are expected to generate enough electricity to supply up to 30% of a store's annual energy requirements. By producing more of its own renewable power, Aldi aims to reduce its reliance on the national grid.
Expansion follows earlier solar programme
The investment builds on an earlier £8.4 million programme to fit solar panels at a further 100 stores during 2025 and 2026, according to Retail Gazette. By the end of 2026, the retailer expects more than 500 of its stores to be equipped with solar power systems.
Aldi UK managing director of national real estate Jonathan Neale said: "We have plenty of space on our store roofs, so it makes sense to use it."
Broader investment in UK estate
Neale added: "We want solar power to become a normal part of how we run our stores, and this investment will help us bring it to even more locations over the coming years. By generating more of our own electricity, we can reduce our reliance on the grid and make our stores more sustainable."
The announcement forms part of Aldi's broader programme of investment across its UK store network. Earlier this year, the retailer committed more than £300 million to refurbishing and expanding existing stores during 2026.
Energy-efficiency measures
The upgrades will also include a range of energy-efficiency initiatives, such as installing doors on refrigerated cabinets and using natural refrigerants. These measures are designed to cut energy consumption and help lower the company's carbon emissions.
