Major ‘Prison Time’ Update Issued Over Putting Union and St George’s Flags on Lamp Posts
A major legal warning has been issued over the growing practice of attaching Union Jack and St George’s flags to public lamp posts, with people potentially facing serious penalties if they ignore a court injunction.
The warning comes as several councils across England take legal action to stop unauthorised flags being attached to public infrastructure. What began as a highly visible display of national pride has developed into a wider dispute involving public safety, highway regulations, council resources and the limits of lawful protest.
The latest development centres on Bristol, where the city council is seeking a High Court injunction aimed at preventing flags from being attached to public furniture, including lamp posts and railings. If such an injunction is granted and subsequently breached, the consequences can be substantially more serious than the ordinary penalties associated with unauthorised advertising or attachments. Reports indicate that a person who deliberately breaches an injunction could face an unlimited fine, and in some circumstances imprisonment.
The legal situation is important because there is a distinction between simply displaying a flag and attaching one to public infrastructure.
People are generally free to display flags on private property, subject to applicable laws and regulations. A person putting a flag on their own home is therefore in a different legal position from someone attaching a flag to a council-owned lamp post.
Public highways and street furniture are subject to separate rules. Lamp posts, barriers, railings and other structures are normally controlled by the relevant highway authority. Unauthorised attachments can be removed, particularly where councils consider them to create safety or maintenance problems.
The issue has become particularly visible since the summer of 2025, when Union Jack and St George’s flags began appearing in large numbers on streets in different parts of England.
The campaign became associated with the group Raise the Colours, whose supporters described the displays as expressions of patriotism. Critics, however, argued that the campaign had become connected to broader disputes about immigration and national identity.
That disagreement has made the issue politically sensitive.
For councils, however, the immediate question is often more practical: who is responsible for maintaining the lamp posts and roads, and what should happen when objects are attached without permission?
Bristol City Council has said that its contractors have removed hundreds of flags. Councillor Stephen Williams said the council had found itself in a “cat-and-mouse” situation, with flags being removed and then put back up shortly afterwards. The council has reportedly spent around £50,000 removing flags, excluding additional staff time spent dealing with the issue.
Other councils have reported similar problems.
Somerset Council said it was considering recovering the cost of removing unauthorised flags from those responsible. It reportedly spent more than £2,900 dealing with unauthorised flags between August 2025 and August 2026.
The figures illustrate why local authorities have become increasingly interested in legal measures rather than relying solely on repeated removal.
Oxfordshire has already taken the matter to the High Court.
In July 2026, Oxfordshire County Council obtained an injunction prohibiting people without consent or legal authorisation from attaching flags to highway structures such as lamp posts, lighting columns, street signs, barriers and railings. The court case specifically addressed the large-scale appearance of Union and St George’s flags across the county.
The court documents provide a detailed picture of the dispute.
The council argued that the unauthorised attachments created difficulties for the authority responsible for maintaining the highway. It also presented evidence concerning alleged hostility and obstruction directed towards workers involved in removing the flags.
The case demonstrates why the legal consequences of ignoring an injunction can be significantly more serious than the original act of putting up a flag.
An injunction is a court order. Once such an order is in force, deliberately breaching it can result in contempt-of-court proceedings. The possible consequences can include substantial fines and, depending on the circumstances, imprisonment.
That does not mean that anyone who puts a Union Jack on a lamp post automatically faces prison.
The legal position is considerably more specific.
A person would first need to be subject to the relevant court order, and the authorities would then need to establish that the order had been breached. The court would consider the circumstances and appropriate penalty.
This distinction is particularly important because some headlines about “prison time” could otherwise create the impression that ordinary flag displays are automatically criminal offences carrying a prison sentence.
The ordinary rules are different.
People who attach flags or other unauthorised material to public infrastructure can face enforcement action and potentially fines. The BBC’s legal explainer reported that unauthorised attachment to lamp posts can result in a fine of up to £2,500. It also noted that councils have discretion over how they enforce the rules and whether prosecution would be proportionate and in the public interest.
The existence of an injunction changes the situation because it creates a direct court obligation.
The latest dispute also involves individuals associated with Raise the Colours.
Ryan Bridge, the group’s founder, has faced separate criminal allegations. Thames Valley Police announced in September that he had been charged with 14 offences relating to alleged incidents in Oxfordshire between January and March 2026. The charges include allegations of threatening or abusive behaviour, racially aggravated offences and common assault. Bridge is due to appear at Oxford Magistrates’ Court in November.
Those allegations should not be confused with the separate legal dispute over flags.
Being charged does not mean that a person has been convicted, and the allegations will be determined through the criminal justice process.
Birmingham City Council has also applied for a High Court injunction. The application seeks to prevent people from attaching flags to public infrastructure throughout the city and names Bridge, several other individuals and people not yet identified.
The council says it has gathered evidence involving alleged harassment, intimidation and obstruction of staff responsible for removing flags.
The Raise the Colours campaign has rejected suggestions that it is attempting to divide communities.
This disagreement illustrates the competing interpretations of the flag displays.
Supporters regard the Union Jack and St George’s Cross as ordinary national symbols and argue that displaying them in public is an expression of patriotism. Critics have linked the campaign to debates surrounding immigration and have raised concerns about whether large-scale displays can make some communities feel unwelcome.
The councils’ legal arguments, however, focus primarily on the use of public infrastructure and the practical consequences of attaching objects to highways.
There are also genuine safety considerations.
Lamp posts are designed for specific engineering purposes. Adding objects to them can create maintenance issues, obstruct workers or potentially affect road users. Flags can also become damaged or detached, creating additional hazards.
For councils responsible for hundreds or thousands of roadside structures, repeated removal can consume staff time and public money.
This is one reason why some authorities have turned to the courts.
The controversy also raises broader questions about public space.
A public lamp post is not the same as a privately owned fence or building. The fact that a flag itself is a lawful and familiar symbol does not automatically give someone permission to attach it to property belonging to another person or organisation.
The same principle applies to other objects.
If a person attached a sign, banner or advertisement to a council-owned structure without permission, the council could take enforcement action regardless of the message being expressed.
The legal debate therefore concerns not simply what the flag represents, but where and how it is displayed.
For supporters of the campaign, this distinction can feel significant because they see the flags as expressions of national identity rather than commercial advertisements.
For councils, the relevant issue is the authority’s responsibility for public infrastructure.
The situation is likely to continue developing as more councils consider whether injunctions are necessary.
Bristol’s application, Birmingham’s legal action and Oxfordshire’s existing injunction show that the issue has moved beyond isolated disputes over individual flags.
It has become a nationwide debate about public space, national symbols and the limits of unauthorised activity on public property.
The possibility of imprisonment has understandably attracted attention, but it is important to understand the legal mechanism behind that possibility.
A person does not normally go to prison merely because they place a Union Jack or St George’s flag on a lamp post. The more serious risk arises where a person deliberately breaches a binding court injunction.
That distinction provides the clearest explanation of the current “prison time” warning.
As councils continue removing flags and campaigners continue defending their right to display them, the courts may increasingly be asked to determine where the boundary lies between lawful expression and unauthorised use of public infrastructure.
For now, the message from councils pursuing injunctions is straightforward: national symbols may be displayed, but attaching them to public highways and street furniture without permission can have legal consequences.
The debate over Britain’s flags is therefore unlikely to disappear. But alongside the arguments about patriotism, national identity and immigration, there is a separate legal question that ultimately matters most: whether individuals have permission to use public infrastructure in the way they have chosen.
That question is now being tested through the courts, and the outcome could determine how councils across England respond to the continued appearance of Union Jack and St George’s flags on lamp posts and other public structures.
