The Rooftop Revolution: How Roof-Mounted Solar Is Driving the UK’s Energy Transition

The UK’s energy system is changing faster than ever — and rooftop solar is at the heart of the transformation. The recently published UK Solar Roadmap sets out an ambitious goal: rising from today’s ~18 GW of installed solar capacity to 45–47 GW by 2030, with potential growth to 54–57 GW if rooftop deployment accelerates. Rooftop solar is a critical element in meeting emissions, energy security and job‑creation targets 

Why Rooftop Solar Matters

• Solar capacity currently sits at 18 GW, of which only about one-third is on rooftops. Much of the unrealised potential lies on commercial roofs, schools and public buildings  .

• Rooftop solar helps businesses save on energy bills, stabilise costs, and demonstrate leadership in sustainability — all while supporting the UK’s clean power ambition.

• Government schemes like the Warm Homes Plan and Future Homes Standard are driving uptake by mandating solar on new buildings and providing financial support for energy-efficient upgrades  .

What This Means for Businesses in the UK

For local businesses across the East of England, rooftop solar offers a wealth of benefits:

• Efficient use of idle roof space — from warehouses to offices and schools.

• Financial savings through reduced electricity bills and attractive tax allowances.

• Accelerated payback timelines as energy prices remain volatile.

• A chance to enhance corporate green credentials and meet ESG targets.
  

  Projects like Portsmouth International Port’s 1.2 MW rooftop installation have demonstrated the impact — saving over £138,000 annually and meeting 21% of their electricity demand  .
