Things that are criminal offences in UK

I like number 9…..

1. It’s Illegal to Handle Salmon Suspiciously

Under the Salmon Act 1986, it’s a criminal offence to handle salmon “in suspicious circumstances.”

This law was introduced to tackle illegal salmon fishing and black-market sales — but its ambiguous wording has made it a favourite example of Britain’s odd legal relics. So, if you’re ever caught with a fish looking a bit shifty… think twice!

2. You Can’t Be Drunk in a Pub

According to the Licensing Act 1872, it’s technically illegal to be “drunk on licensed premises” — meaning you can be arrested for being drunk in a pub.

The law aimed to maintain order in public houses during the Victorian era, but it’s ironic that the very place built for drinking could also get you fined for doing just that.

3. No Flying a Kite in a Public Place

Under the Metropolitan Police Act 1839, flying a kite “to the annoyance of any person” in a public area is against the law.

It was originally designed to prevent public disturbances and damage in crowded city spaces. While rarely enforced, technically you could still be in breach of the law for having too much fun in the park on a windy day.

4. It’s an Offence to Be Drunk in Charge of a Cow

The Licensing Act 1872 strikes again — this time making it illegal to be “in charge of any steam engine, horse, or cow” while intoxicated in a public place.

Back when cows and carriages were part of everyday life, this law aimed to protect public safety. While it sounds silly today, you’d technically be breaking the law if you took your cow for a tipsy stroll.

5. You Mustn’t Beat a Carpet in the Street

Under the Town Police Clauses Act 1847, it’s illegal to beat or shake any carpet, rug, or mat in the street — except doormats, and only before 8am.

The intention was to prevent dust and debris from dirtying public roads, but it remains a peculiar reminder of Victorian-era cleanliness standards.

6. It’s Illegal to Wear Armour in Parliament

A statute from 1313 still bans Members of Parliament from wearing armour within the Palace of Westminster.

This medieval law was introduced by King Edward II to prevent armed confrontations among nobles during heated debates. Thankfully, modern MPs stick to suits and ties instead of chainmail.

7. Placing a Postage Stamp Upside Down Is Treason

It’s a well-known myth with a kernel of truth. Under historic treason laws, defacing or disrespecting the image of the monarch — including on a postage stamp — was once considered an act of treason.

While this isn’t enforced today, flipping a stamp upside down with the King’s image could still be viewed as a symbolic insult to the Crown.

8. It’s Illegal to Gamble in a Library

Several local council bylaws make it an offence to gamble in public libraries.

This includes card games, lotteries, and betting of any kind. The rule was meant to preserve quiet, studious spaces — not turn them into makeshift casinos.

9. Dying in Parliament Is Illegal (Sort Of)

One of Britain’s most famous legal myths is that it’s illegal to die in the Houses of Parliament.

While there’s no actual law forbidding it, the belief stems from the idea that anyone who dies on royal property is entitled to a state funeral — a logistical and ceremonial nightmare. Parliament has clarified that this isn’t true… but the myth lives on.

10. It’s Illegal to Knock on Someone’s Door and Run Away

Under the Metropolitan Police Act 1839, causing a “nuisance” by persistently knocking on doors or ringing bells is a punishable offence.

So yes — the childhood prank of “knock, knock, run” could technically earn you a visit from the police.

11. Carrying a Plank of Wood Along the Pavement Is Forbidden

The same 1839 Act also makes it illegal to carry a plank of wood along a pavement in London.

The law was introduced to prevent injury and obstruction on narrow Victorian streets — though these days, it’s mostly a fun fact rather than a real concern.

12. Handling Fish Other Than Salmon Suspiciously

Not just salmon! The Fishery Limits Act and other local statutes extend similar suspicious-handling rules to other fish species.

So whether it’s cod, trout, or mackerel — best not to act too shady with seafood.

13. Keeping a Pigsty in Front of Your House Is Illegal

Under the Town Police Clauses Act 1847, it’s an offence to keep a pigsty at the front of your property unless the local authority approves it.

Victorian hygiene laws were serious business — and this one was aimed at keeping towns sanitary (and less smelly).

14. It’s Illegal to Jump the Queue in the Tube

While not an ancient law, the Transport for London Railway Byelaws make it a punishable offence to jump the queue when boarding a London Underground train.

You could technically be fined for barging ahead — though you’re more likely to face disapproving looks from fellow commuters.

15. Pretending to Be a Member of the Armed Forces Is a Crime

Under the Uniforms Act 1894, it’s illegal to wear a British military uniform without permission — or to impersonate a member of the armed forces.

The rule was introduced to prevent fraud and protect the honour of genuine servicemen and women.
