Damaging someone else's property (from a smashed window to graffiti or a deliberate fire) can be a criminal offence in England and Wales. The main law is the Criminal Damage Act 1971, and the penalties range from a fine to life imprisonment in the most serious cases. This guide explains, in plain English, what criminal damage is, the key variants, and the defences.
The basic offence
Under section 1(1) of the Criminal Damage Act 1971, a person commits criminal damage if they, without lawful excuse, destroy or damage property belonging to another, intending to do so or being reckless as to whether such damage would occur.
The key elements are:
- Damage or destruction, "damage" is interpreted broadly and can include temporary or non-permanent harm (for example, graffiti that costs money to remove).
- Property belonging to another, generally tangible property owned, possessed or controlled by someone else. Damaging your own property is usually not this offence (but see arson and the endangerment offence below).
- Intention or recklessness, you either meant to cause the damage, or you saw a risk of it and went ahead unreasonably.
Arson and endangering life
The Act creates more serious variants:
- Arson, criminal damage caused by fire is charged as arson and carries a much higher maximum penalty.
- Aggravated criminal damage / arson endangering life, where the damage is caused with intent to endanger another's life, or recklessness as to whether life is endangered. These can carry up to life imprisonment, and can apply even to your own property if life is endangered.
Penalties and where the case is heard
Penalties depend on the seriousness and value involved:
- Low-value criminal damage (currently where the value is £5,000 or less) is usually dealt with in the magistrates' court, with lower maximum penalties.
- Higher-value or more serious cases can go to the Crown Court, where simple criminal damage carries a maximum of ten years' imprisonment, and arson/endangerment offences can carry life.
Defences and "lawful excuse"
The Act provides specific defences of lawful excuse (section 5), including where:
- you honestly believed the owner consented (or would have consented) to the damage; or
- you damaged property to protect other property in immediate need of protection, and the action was reasonable in the circumstances.
These beliefs are judged on what the defendant honestly believed, even if the belief was mistaken, though the protection must be genuinely directed at property. General defences (such as duress, or lack of the required intent/recklessness) may also apply.
Why it matters
Disputes between neighbours, businesses, landlords and tenants can spill over into property damage, and what feels like "taking matters into your own hands" can be a criminal offence. If you are accused (or considering action that might damage another's property) take advice.
Key takeaways
- Criminal damage is destroying or damaging another's property, intentionally or recklessly, without lawful excuse (Criminal Damage Act 1971, s 1).
- Arson (damage by fire) and endangering life are more serious, carrying up to life imprisonment.
- Penalties scale with value and seriousness; simple criminal damage carries up to ten years.
- Lawful excuse defences include honest belief in consent, or reasonable action to protect other property (s 5).
