London Tenants Get 15% Cheaper Power From Their Own Roofs

Reg Platt doesn't look like your typical solar energy revolutionary, but the grizzled entrepreneur is proving that clean power can actually save people money right now.

His company, Emergent Energy, just cracked a code that's eluded the renewable energy industry for years. They're installing solar panels on the flat roofs of council housing in Hackney, London, and selling that power directly to the residents living below at rates 15% cheaper than the grid.

Here's how it works. Emergent installs solar panels on sprawling apartment rooftops, then manages them as a mini power network. Residents get billed directly for their electricity, and when the panels generate more than neighbors need, the surplus gets sold back to the National Grid.

The earnings cover the installation costs completely. No government subsidies. No taxpayer money. The system literally pays for itself while cutting bills for families who need it most.

So far, 800 residents across 28 apartment blocks are benefiting from cheaper, cleaner power. The project won the 2025 Ashden Award for Breaking Barriers, and it's the largest deployment in UK social housing history.

Platt wasn't always an energy entrepreneur. He started as a musician and climate activist, frustrated that protests weren't creating change fast enough. After studying environment and policy, he worked with think tanks shaping UK energy policy before his entrepreneur wife opened his eyes to the power of business.

"I learned that there's this thing you can do: start a business," Platt says. He founded Emergent in 2016 to put his policy knowledge into action.

The Ripple Effect

The potential here is massive. The UK has 5 million apartments, and 2 million of them are social housing like Hackney's. Not every building will work, but Platt estimates a huge portion could follow this model.

That means millions of British families, many living paycheck to paycheck, could soon get cheaper electricity while helping the planet. They become producers of clean energy, not just consumers.

The timing couldn't be better. Energy prices have soared, and centralized power systems have proven fragile during global turmoil. Platt's approach shows that local, community-owned renewable energy isn't just idealistic, it's practical and profitable.

His model proves something critics of green energy hate to admit: renewable power can save regular people money right now, without costing taxpayers a penny.

Emergent is now poised to expand across the country, turning overlooked rooftops into power stations and giving communities control over their own energy future.

For families in Hackney paying 15% less each month, the renewable energy revolution isn't coming someday, it's already lighting their homes.
