From the 27 August 2026 the Government legalised the sale and use of plug‑in solar panels, sometimes referred to as balcony solar or plug-and-play solar systems.
These systems offer a relatively simple way for residents to generate renewable electricity without the need for a traditional rooftop installation. Unlike conventional solar arrays, plug-in systems can be installed by residents and connected directly to a standard domestic socket.
While the technology presents opportunities to support sustainability goals and may help residents manage energy costs, it also raises important questions for public service organisations responsible for managing buildings, housing and community safety.
For risk managers, it’s another example of how emerging technologies can create new exposures that need to be understood and controlled before widespread adoption occurs.
Why should risk managers pay attention?
The introduction of resident-installed energy systems changes the risk landscape for public service organisations. Unlike traditional renewable energy projects, plug-in solar panels may be installed with limited visibility for landlords.
Housing providers, local authorities and other property owners may have limited visibility of installations taking place within their buildings. Residents may view plug-in solar as a straightforward consumer product, while asset managers must consider wider implications, including:
- Fire safety
- Electrical integrity
- Building construction risks
- Resident behaviour
- Lease and tenancy conditions
- Inspection and maintenance requirements.
The challenge is achieving the right balance between supporting sustainability initiatives and maintaining appropriate levels of safety and governance. It's not about stopping innovation but enabling it safely.
Fire safety considerations
One of the key concerns associated with plug-in solar panels is the potential impact on fire risk.
While solar technology itself is well established, the location of installations can significantly affect risk. In higher-rise buildings, fires that originate externally have the potential to spread vertically, potentially involving balconies, façade systems or combustible materials.
For public service housing providers, this means considering not just the panel itself but the wider building environment.
Questions risk managers may wish to ask include:
- Is the building low, medium or high rise?
- Are there combustible materials present within balcony or external wall systems?
- Would the installation affect assumptions made within existing fire risk assessments? If so, reassessment will be needed.
- Is there a process for residents to seek planning consent or landlord approval before installation?
These considerations are particularly important where external wall systems already require enhanced fire risk management arrangements.
Understanding the electrical risks
As with any electrical equipment, safety depends on both product quality and proper installation.
Although plug-in solar systems are designed to be simple to use, risks can arise where electrical infrastructure is outdated, damaged or unsuitable. Poor installation practices, inappropriate connections or damaged cabling can all increase the likelihood of overheating or fire.
Public service organisations should ensure residents understand safe installation requirements and are aware of any restrictions applying to their properties.
Good practice may include:
- Ensuring electrical installations have been inspected within appropriate timescales.
- Providing clear guidance to residents on permitted installations.
- Discouraging the use of extension leads and unsuitable sockets.
- Communicating registration requirements where applicable.
- Establishing clear reporting routes for defects or concerns.
- Clear and proactive resident communication can often prevent issues before they arise.
Governance and property management challenges
One of the more difficult aspects of plug-in solar technology is that responsibility may be shared across multiple parties.
Residents may purchase equipment independently, while landlords remain responsible for wider building safety considerations. Facilities teams, housing managers, fire safety specialists and risk managers may all have a role to play.
Developing a clear organisational position can help avoid confusion and inconsistent decision-making. This could include:
- A documented approval process
- Defined responsibilities between departments
- Clear resident communications
- Guidance for managing requests and enquiries
- Procedures for identifying unauthorised installations.
For organisations with large property portfolios, having a consistent approach will become increasingly important as uptake grows.
Supporting sustainability without increasing risk
As with many emerging technologies, successful adoption depends on understanding the associated risks and ensuring suitable controls are in place.
As awareness and availability increase, organisations need to treat plug-in solar panels as an emerging risk, monitoring uptake, reviewing experience and ensuring governance arrangements remain fit for purpose.
Risk managers are uniquely positioned to bring together sustainability, safety, compliance and operational considerations. By engaging early with estates teams, housing colleagues and residents, they can help organisations make informed decisions that support both environmental ambitions and public safety.
Top tips for ALARM members
- Review existing policies and procedures for resident-installed renewable technologies.
- Consider whether fire risk assessments need to account for plug-in solar installations.
- Ensure responsibilities are clearly defined across housing, estates and risk teams.
- Communicate expectations and approval requirements to residents clearly and consistently.
- Monitor developments in guidance, regulation and industry best practice as adoption increases.
As plug-in solar technology becomes more common, organisations that take a proactive approach to governance and risk management will be best placed to realise the benefits while protecting residents, assets and communities.
Legislative note
The legalisation of plug-in solar panels referenced in this article relates to Great Britain. ALARM members operating in Scotland should continue to review the latest Scottish Government, building standards and fire safety guidance, as regulatory requirements and implementation arrangements may differ.
