UK Government Announces Expansion of Solar Access

But What Could Plug-In Solar Mean for Safety and Standards?

The UK Government recently announced plans to move “further and faster” towards greater energy security, with solar power expected to play a major role in the country’s transition towards more sustainable energy sources.

Part of this ambition includes exploring new ways for households to access solar technology, particularly for those who have historically been excluded from rooftop installations, such as people living in flats or apartments.

While increasing accessibility to renewable energy is widely welcomed across the electrical industry, the announcement has also sparked discussion about how emerging technologies, such as plug-in or balcony solar systems, can be introduced safely and responsibly within the UK market.

Traditional rooftop or even ground-mounted solar installations are not always an option for everyone. Property ownership, roof orientation, planning restrictions, and shared buildings can make installation difficult or impossible for many households.

Plug-in Alternatives

Government proposals suggest that these ‘plug-in’ alternative solutions could help widen participation in renewable energy, allowing more people to generate their own electricity, reducing their household costs and contributing to reducing overall carbon emissions.

One of the advantages often highlighted is flexibility, with some plug-in solar systems being available to potentially move with the occupier when they relocate, offering a portable renewable energy option rather than a fixed installation tied to one property.

The Government has also indicated that increasing solar adoption forms part of a broader ambition to significantly expand national solar capacity by 2030, contributing towards energy security and reducing reliance on imported fossil fuels.

International examples show that similar systems are already being adopted in countries including Germany, the Netherlands, France and Italy, where apartment living is common and space for traditional installations can be limited. Learning from these markets could provide useful insights into how these technologies can be introduced safely and effectively in the UK.

But as often happens, with new opportunities come important questions about how these types of systems might be implemented in practice.

Electrical installations in the UK are subject to strict regulations designed to minimise risk, particularly in domestic environments. Over many years, significant work has gone into developing safety standards covering equipment positioning, fire risk, cable routing, circuit protection, and suitability of installations within different property types.

Some within our industry have voiced concern that making solar products widely available through mainstream retail channels could create confusion around installation requirements or lead to systems being fitted without appropriate technical assessment.

Considerations raised across the sector include:

• ensuring electrical systems are installed safely and correctly
• avoiding inappropriate cable routing, particularly through windows or external openings
• confirming that existing electrical installations are suitable for connection
• maintaining compliance with fire safety regulations
• ensuring correct protection devices are in place
• avoiding overloading the system with multiple installations

Safety Standards

Electrical systems interact with the wider infrastructure of a property, and what may appear straightforward at first glance can involve technical considerations that are not always visible. And so, maintaining high standards of safety remains essential, particularly where equipment connects directly into domestic electrical circuits.

It is encouraging that other European countries have already seen growth in this type of solar technology, particularly in urban environments where traditional installations are less practical. Germany in particular has seen increasing uptake of small-scale balcony solar systems, supported by guidance designed to ensure installations remain safe and compliant.

Understanding how these markets have addressed safety, certification, consumer guidance and installation best practice could help shape a framework that supports both innovation and protection. And engaging with experienced electrical professionals during the development of new policies will be an important part of ensuring that any new solutions are introduced responsibly, in our opinion.

Tomlinson Longstaff Managing Director, Alicia Reid, sees clear potential in widening access to renewable technology, particularly where traditional solar installations are not feasible:

“It’s good that the Government are making options for people where regular solar isn’t an option, like for those who live in flats. It doesn’t 100% replace rooftop solar, but it will be interesting to see how it pans out and follow along with the developments.”

The Positives

Providing more people with the opportunity to generate renewable energy has got to be a positive step, provided that safety remains central to how new technologies are introduced. Expanding choice while maintaining strong technical standards will help ensure the transition to renewable energy is both practical and responsible. And as the industry continues to evolve, collaboration between Government, manufacturers and qualified electrical professionals will be key to ensuring innovation works in the real world.

Tomlinson Longstaff has long supported the adoption of renewable technologies where they are appropriate for the property and installed in accordance with recognised safety standards. Solar power continues to play an important role in improving energy efficiency, reducing environmental impact and supporting long-term sustainability goals, in domestic, commercial and industrial settings.

As new solutions emerge, maintaining a balanced approach that considers both opportunity and safety will help ensure progress benefits everyone, and the planet. But the transition to cleaner energy is not just about technology, it is also about implementing it in ways that are safe, practical and built to last.
