Emergency Lighting in Toilet Cubicles

In any office building, ensuring the safety and well-being of employees and visitors is of paramount importance. Emergency lighting plays a vital role in providing illumination during power outages or emergency situations, aiding in the safe evacuation of occupants. However, when it comes to toilet cubicles in office buildings, there may be some confusion regarding the necessity of emergency lighting. In this article, we will delve into the regulations set forth by the United Kingdom (UK) and address the question: “Do I Need Emergency Lighting in Toilet Cubicles in an Office Building in UK?”

Understanding Emergency Lighting Regulations

Emergency lighting is a crucial aspect of building safety, specifically designed to provide illumination when the mains power supply fails. It ensures that individuals can safely navigate out of a building during emergencies such as fire incidents, power failures, or other hazardous situations. The UK has established comprehensive regulations to govern the installation and usage of emergency lighting systems to ensure the safety of occupants.

The Importance of Emergency Lighting in Office Buildings

Office buildings often accommodate employees and visitors, making emergency lighting systems indispensable. In the event of an emergency, such as a fire or a power outage, panic and confusion may ensue, making it crucial to have appropriate lighting in place to guide individuals to safety. Emergency lighting serves as a critical aid in the evacuation process, especially in areas where visibility may be compromised, such as corridors, staircases, and communal spaces.

The Extent of Emergency Lighting Coverage

According to UK regulations, emergency lighting is typically required in various areas of an office building, including escape routes, open areas larger than 60 square meters, and rooms that accommodate more than ten people. However, when it comes to toilet cubicles, the regulations are unclear.

Toilet Cubicles and Emergency Lighting Regulations

In the UK, the requirements for emergency lighting in toilet cubicles within office buildings are outlined in the Building Regulations, related guidance documents and BS 5266.

Generally, emergency lighting is required in escape routes, circulation areas, and open areas larger than 60 square meters within a building. However, the regulations do not explicitly specify emergency lighting for individual toilet cubicles.

The main objective of emergency lighting is to ensure the safe evacuation of occupants during a power failure or emergency situation. In general, toilet cubicles are not considered high-risk areas in terms of BS 5266, and while toilet cubicles are not typically considered escape routes or open areas, providing emergency lighting within or near toilet facilities can enhance safety and aid occupants in finding their way out during an emergency.

The need for emergency lighting within toilet cubicles is not explicitly mandated by UK regulations; other than clause of the BS5266-1:2016, there is limited guidance.

Considerations for Toilet Cubicles

The above clause of the BS5266-1:2016 specifically refers to multiple closed facilities without borrowed light.

Although emergency lighting within toilet cubicles may not be mandatory, certain factors should be considered to ensure the safety and well-being of individuals using these facilities. These considerations include:

  1. Cubicle door height: The height of cubicle doors should be considered; for example, if the doors are full height, it will prevent the spill of borrowed light from the area outside of the cubicle.
  2. Proper Illumination: Adequate lighting should be provided within the toilet area, including the entrance, corridors, and areas outside the cubicles. Well-lit spaces enhance visibility and help occupants locate the nearest emergency exit.
  3. Exit Signage: Clear and visible exit signs should be prominently displayed to guide individuals towards the nearest emergency exit. These signs should be placed strategically, both within the washroom area and the surrounding spaces.
  4. Maintaining Emergency Lighting Systems: Regular inspection, testing, and maintenance of the emergency lighting systems should be conducted in accordance with the UK regulations. This ensures that the system is fully functional and ready to provide illumination during emergencies.

Expert Recommendations

While not strictly required by regulations, it is important to recognize the potential risks associated with the absence of emergency lighting in toilet cubicles within an office building. If a toilet cubicle with a full-height door lacks emergency lighting, individuals could become trapped in total darkness during an emergency or power outage. In such cases, the responsibility falls on the employer to consider the safety and well-being of their employees.

Employers should consider the specific needs and circumstances of their office buildings. Conducting a comprehensive risk assessment and seeking guidance from safety experts can help determine the most suitable approach to ensure the safety of occupants in emergency situations.

Although UK regulations do not explicitly mandate emergency lighting within toilet cubicles, some experts recommend its installation. This additional lighting can provide individuals with reassurance and a sense of security, especially if the cubicles are windowless or located far from natural light sources.

It is important to stay updated on any changes or revisions to UK regulations and guidelines concerning emergency lighting. By remaining informed, employers can maintain compliance and enhance the overall safety of their office buildings.

Remember, consulting with professionals familiar with local regulations, such as Building Control Officers (BCO) or safety experts, is crucial for obtaining accurate and specific guidance tailored to your office building’s requirements.

Taking a Proactive Approach to Safety

It is essential for organizations to prioritize the safety and well-being of their occupants. By going beyond the minimum requirements, organizations can demonstrate a proactive approach to safety and create a culture of preparedness within the workplace.

Before installing emergency lighting within toilet cubicles, consider conducting a comprehensive risk assessment for your office building. Evaluate factors such as the size of the building, the number of occupants, the layout of washroom facilities, and the presence of alternative lighting sources. This assessment will help determine the necessity and feasibility of installing emergency lighting within the cubicles.

Additionally, consult with Building Control Officers (BCO) to ensure compliance with relevant regulations and industry best practices. They can provide valuable insights, and guidance tailored to your specific circumstances, moreover, the BCO have the final say on the building occupation.

Remember that safety should always be a priority. Whether or not emergency lighting is installed within the toilet cubicles themselves, maintaining a well-designed, properly illuminated, and regularly inspected emergency lighting system in the surrounding areas is crucial for a safe and secure office building.


In conclusion, while UK regulations do not explicitly require emergency lighting within toilet cubicles in an office building, there are compelling reasons to consider installing it. Enhanced visibility, reduced panic and anxiety, improved navigational aid, compliance with accessibility standards, and proactive emergency preparedness are among the benefits of having emergency lighting within the cubicles.

The Benefits of Emergency Lighting in Toilet Cubicles

While not required by UK regulations, there are several benefits to installing emergency lighting within toilet cubicles in an office building. These benefits include:

  1. Enhanced Visibility: Emergency lighting within the cubicles ensures that individuals have clear visibility.
  2. Reduced Panic and Anxiety: In emergencies, such as power outages or fires, people may experience heightened panic and anxiety. Emergency lighting within the toilet cubicles reassures occupants, helping them feel more secure and less anxious during such incidents.
  3. Compliance with Accessibility Standards: Installing emergency lighting within toilet cubicles can also contribute to compliance with accessibility standards. Individuals with visual impairments or disabilities may require additional lighting support to navigate and use the facilities independently. Emergency lighting ensures equal access and inclusivity for all occupants.
  4. Emergency Preparedness: While toilet cubicles may not be considered high-risk areas, emergencies can occur anywhere within a building. Installing emergency lighting within the cubicles demonstrates a proactive approach to emergency preparedness, reinforcing the commitment to occupant safety.
