UK retailers to sell plug-in balcony solar from August
New UK legislation will allow major high-street retailers to sell plug-in solar panels to renters and flat owners from August 27, opening a new consumer market for microgeneration amid volatile energy prices.
The British government has legalised plug-in balcony solar panels, permitting major retailers to sell the devices to households from 27 August. The legislative change clears the way for stores like Currys, B&Q, Asda, Screwfix, and Wickes to bring a product already common across Europe to the UK mass market. Amazon has also engaged with the government on the new retail guidelines.
This unlocks a distinct new consumer segment for the domestic solar industry: renters and flat occupants who lack rooftop access. Until now, the UK's record solar adoption—269,000 installations completed last year, equating to one every two minutes—was largely restricted to homeowners able to fund professional rooftop setups.
The plug-in systems, which feed power directly into a property's circuit via a standard three-prong socket, typically carry an 800-watt capacity. Expected to retail for at least £400, they can reduce annual energy bills by between £70 and £110, offering a payback period of four to seven years. The rollout comes as households increasingly seek green home upgrades to offset soaring global energy prices driven by the war in Iran.
Millions of households in Spain and Germany already use these systems, known there as Balkonkraftwerk. Chris Hewett, chief executive of Solar Energy UK, said the move will bring “cheap, clean power to households that have not been able to access these benefits before”. He added: “Our industry is working closely with government to ensure that all customers can have confidence in the safety and reliability of these new technologies.”
The regulatory shift could also accelerate the adjacent market for domestic plug-in batteries. According to the i Paper, the government is considering bulk-purchasing these storage devices for low-income homes to help them balance grid supply and demand. Rob Hallifax, a co-founder of Windfall Energy, described the legislation as a “massive win for consumer energy independence, and a huge leap forward for anyone who has previously been locked out of the energy transition”.
Industry figures are, however, urging realistic expectations regarding the immediate financial returns. “Coming into force in late August means generation will naturally decline as we head into autumn and winter,” Hallifax noted. He also cautioned that consumers still require a sunlit outdoor space and may need formal permission from a landlord or freeholder before installing the panels.
