The Rise of Solar Energy
A nationwide rooftop solar revolution is underway, and it’s set to transform how Britain powers homes, businesses, and public spaces. As part of its wider Plan for Change, the government has launched an ambitious new Solar Roadmap designed to massively scale up solar deployment—bringing lower energy bills, enhanced energy security, and a boost in green jobs.
And with support for solar soaring—88% of the British public now in favour—there’s never been a better time to harness the power of the sun.
The Rise of Rooftop Solar
The government aims to increase the UK’s solar capacity to 45–47 GW by 2030, more than doubling current levels. This growth will be driven by widespread deployment of rooftop solar panels across homes, warehouses, car parks, schools, and hospitals.
Already, more than 1.5 million UK homes have solar panels installed, and installation rates are climbing fast. In January 2025 alone, nearly 15,500 rooftop systems were fitted to existing homes—a 16.5% rise compared to the year before.
With future plans requiring all new-build homes to include solar panels as standard under the Future Homes Standard, the government is sending a clear signal: solar energy is no longer niche—it’s the new normal.
This shift also comes as proposals to raise the minimum EPC rating for rented homes to Band C gain momentum—putting pressure on landlords and property owners to invest in energy efficiency. Rooftop solar is one of the most effective ways to meet these future EPC requirements, while also delivering tangible financial benefits and supporting the UK’s decarbonisation goals.

Smart Solar Savings
For families and businesses alike, the financial case for solar is becoming increasingly attractive. Households that install rooftop panels could save around £500 per year on their energy bills, according to government estimates. Case studies from across the UK show even greater savings when battery storage and electric vehicle (EV) charging points are added into the mix.
One homeowner in Leeds recently reported that his solar setup not only powered his home and EV for months, but resulted in a negative electricity bill—he was owed money from the grid.
Plug-In Solar Panels: A Game-Changer for Renters
Even those without access to traditional rooftop installations are beginning to benefit. Portable “plug-in” solar panels—already popular in countries like Germany and Spain—are gaining interest in the UK as a low-cost, accessible alternative for renters and flat-dwellers.
These compact systems can be fitted to balconies, placed in gardens, and plugged directly into a standard socket, feeding solar energy into the home’s supply. Because they don’t require structural installation or landlord permission, they’re ideal for people in rented or shared properties. They’re also easy to relocate, making them perfect for tenants who move frequently.
While not currently mainstream in the UK, there’s growing public and policy interest in expanding access to plug-in panels as part of the wider clean energy transition. If supported through future guidance or incentives, these systems could unlock solar savings for millions more households—making clean, affordable energy truly accessible to all.
Solar for Business
Homes aren’t the only places reaping the rewards of solar energy. For businesses, rooftop solar represents a huge opportunity to cut costs, reduce carbon footprints, and futureproof operations.
According to the government’s clean power strategy, just 20% of the UK’s largest warehouses could contribute up to 15 GW of solar capacity—equivalent to half the country’s planned solar growth by 2030.
Recent investments—like the £200 million set aside for rooftop solar in schools and hospitals—demonstrate how solar can deliver significant returns, with one hospital alone forecast to save £200,000 per month thanks to solar panels.
And let’s not forget the environmental benefits: the UK’s first fully solar-powered park and ride facility in Leeds is estimated to offset 471 tonnes of carbon annually—equivalent to removing over 200 petrol or diesel cars from the road.

Why should my business consider installing rooftop solar panels?
Rooftop solar helps businesses cut energy bills, reduce carbon emissions, and show commitment to sustainability. It’s also a smart long-term investment that can future-proof your energy costs.
Can my commercial premises support rooftop solar?
Most flat or pitched commercial roofs are suitable for solar. A quick site survey can assess roof size, orientation, and structural suitability to determine your solar potential.
How much could my business save with rooftop solar?
Savings depend on system size and energy usage, but many businesses see a significant drop in daytime electricity costs. You can also benefit from exporting surplus power back to the grid.
Is rooftop solar financially viable for SMEs?
Yes—solar has become much more affordable, and options like Power Purchase Agreements (PPAs) or finance deals mean you can often install with little to no upfront cost.
How can Black Sheep Utilities help my business go solar?
We provide expert advice on energy procurement to complement your solar setup—helping you secure the best green tariffs, off-peak rates, and export options to maximise your savings.
