The unauthorised display of flags on public highways and structures presents a complex challenge for councils, encompassing legal, safety, cultural, and resource considerations.

Governed by regulations such as the Town and Country Planning (Control of Advertisements) (England) Regulations 2007 and the Highways Act 1980, councils are tasked with ensuring compliance while addressing safety risks. These include obstructed visibility and potential hazards from unsecured flags. Cultural sensitivities further complicate the issue, as flags can evoke strong emotions and, in some cases, incite division or conflict.

Enforcement is necessary but is resource-intensive, requiring monitoring, legal action and public engagement. To navigate these challenges, councils must strike a balance between upholding the law, ensuring public safety, and respecting community diversity, fostering a framework that promotes unity and responsible expression.

Flags have long been a vibrant medium for expressing identity, celebrating milestones, and conveying messages. Yet, when displayed without proper authorisation on public highways and structures, they can present a host of challenges for local councils. From legal and safety concerns to cultural sensitivities and resource implications, the issue is far from straightforward.

The legal landscape: what the law says

In the United Kingdom, according to the Town and Country Planning (Control of Advertisements) (England) Regulations 2007, flags are classified as advertisements.

National flags, commonwealth flags, and those of recognised international organisations are generally exempt from requiring express consent. However, other flags, such as those used for advertising or personal messages, may need approval from the local planning authority. This ensures the display of flags aligns with planning policies and does not disrupt the visual or functional integrity of public spaces.

The Highways Act 1980 further prohibits unauthorised advertisements, including flags, on public highways or structures. Section 132 of the Act explicitly states that affixing any object to a highway without lawful authority constitutes an offence.

As Highway Authorities (or Roads Authorities in Scotland), councils are tasked with ensuring public highways remain free from such obstructions. This responsibility is critical not only for maintaining order but also for ensuring the safety and accessibility of public spaces.

In cases where unauthorised flags cause harassment, alarm, or distress, the Anti-social Behaviour, Crime and Policing Act 2014 may also come into play. Councils can leverage this legislation to address persistent or community-impacting behaviour. This is particularly relevant in situations where the display of certain flags escalates tensions or disrupts public order.

Safety first: the risks of unauthorised flags

Beyond legalities, unauthorised flags can pose significant safety hazards. Flags attached to lampposts, traffic lights, or bridges may obstruct visibility, increasing accident risk. For example, a flag draped over a traffic signal could obscure its lights.  Similarly, flags that are poorly secured or affixed to unstable structures can become dangerous projectiles in adverse weather conditions.

Under the Health and Safety at Work etc. Act 1974, councils are legally obligated to ensure public safety in areas under their jurisdiction. This includes the removal of unauthorised flags that could pose risks. Failure to act could expose councils to liability for any resulting harm. For instance, if a flagpole were to collapse and injure a pedestrian, the council could face legal action for negligence.

Navigating cultural sensitivities

Flags are potent symbols, capable of uniting or dividing communities. While many are displayed with positive intentions, others, such as political or sectarian flags, can provoke tension and disrupt social harmony. In extreme cases, the display of certain flags may even breach the Public Order Act 1986, which prohibits material intended to incite hatred or violence. For example, a flag associated with a controversial political movement might be perceived as inflammatory, leading to public unrest.

Councils must tread carefully, balancing the right to free expression with the need to foster inclusivity and community cohesion. Collaboration with police and other agencies is often essential to address incidents that could escalate into broader social conflicts. For instance, councils might work with local community leaders to mediate disputes and promote understanding.

Enforcement: a resource-intensive responsibility

Councils have a range of tools at their disposal to tackle unauthorised flag displays. The Town and Country Planning Act 1990 allows them to issue enforcement notices for the removal of unauthorised advertisements, with non-compliance potentially leading to prosecution and fines. Similarly, the Highways Act 1980 empowers councils to remove obstructions or hazards from public highways. These measures are crucial for maintaining the integrity and safety of public spaces.

However, enforcement is not without its challenges. Monitoring public spaces, coordinating with enforcement teams, and pursuing legal action can strain council resources. For example, identifying unauthorised flags often requires regular inspections, which can be time-consuming and costly. Additionally, legal proceedings to enforce compliance can be lengthy and resource intensive.

To mitigate these challenges, councils may consider adopting proactive measures. For instance, forming dedicated teams to manage unauthorised advertisements can streamline enforcement efforts. Leveraging technology, such as CCTV and reporting apps, can also enhance efficiency by enabling quicker identification and response to unauthorised displays. Engaging with community groups to promote compliance and awareness of regulations can further reduce the prevalence of unauthorised flags.

Striking the right balance

The unauthorised display of flags on public property is a multifaceted issue that demands a nuanced approach. While councils must uphold the law and ensure public safety, they must also respect the diverse identities and perspectives within their communities. This requires a delicate balancing act.

In the end, the goal is to create a balanced framework that allows for the celebration of identity and expression, while safeguarding public spaces and community harmony. By doing so, councils can ensure that flags remain a symbol of pride and unity for all.
