Most articles about burglary law online describe England and Wales, but Northern Ireland has its own statute and its own police service. This article covers Northern Ireland only. It summarises the Theft Act (Northern Ireland) 1969 as published on legislation.gov.uk, the Police Service of Northern Ireland (PSNI) “House Security” page and the nidirect page “Support services for victims”. The site’s article on what legally counts as burglary in England and Wales covers the Theft Act 1968, and its article on housebreaking in Scotland covers the Scottish position. This is general information, not legal advice.
The Northern Ireland definition
Section 9(1) of the Theft Act (Northern Ireland) 1969 says a person is guilty of burglary if either of two things is true. Under paragraph (a), the person enters any building or part of a building as a trespasser and with intent to commit an offence listed in subsection (2). Under paragraph (b), having entered a building or part of a building as a trespasser, the person steals or attempts to steal anything in it, or inflicts or attempts to inflict grievous bodily harm on anyone there.
The offences in subsection (2) for the entry-with-intent route are stealing anything in the building or part of it, inflicting grievous bodily harm on anyone there, and doing unlawful damage to the building or anything in it. Two points follow from the wording. A person who enters as a trespasser with intent has committed burglary even if nothing is taken, and a person who enters without permission and then steals has committed it even if they had no intention when entering.
Inhabited vehicles and vessels
Section 9(3) extends references to a building to an inhabited vehicle or vessel. It applies at times when the person who has a habitation in it is not there, as well as when they are. For householders this covers caravans, motorhomes and houseboats that are lived in, so an owner who uses one as a home has the same statutory protection as in a house.
Maximum penalty
Under section 9(4), a person guilty of burglary is liable, on conviction on indictment, to imprisonment for a term not exceeding fourteen years. That is a maximum, not what a typical offender receives; the actual sentence depends on the facts.
Aggravated burglary
Section 10 creates aggravated burglary. A person commits it if they commit any burglary and at the time have with them a firearm or imitation firearm, a weapon of offence or an explosive. The Act defines a firearm as including an airgun or air pistol, an imitation firearm as anything with the appearance of a firearm whether or not it can be discharged, a weapon of offence as any article made or adapted to cause injury or incapacitate a person or intended by the person for that use, and an explosive as an article made or intended to produce a practical effect by explosion. On conviction on indictment the penalty can be imprisonment for life.
What PSNI says about prevention
PSNI’s House Security page says a good many burglaries are committed by opportunistic criminals who use open or unlocked doors and windows for quick and easy access, and that good home security such as window and door locks is the best way to reduce the chance of being burgled. It advises checking all doors and windows for weaknesses, fitting mortise locks to front and back doors, fitting locks to downstairs or easily reached windows, keeping house and car keys away from doors and windows, and making sure any burglar alarm is properly installed and works. It says the easiest way for a thief to steal a car is now often to break into the house and take the keys, so car keys should be kept where they will not be easily found.
The page states that properties without security measures are ten times more likely to be burgled than those with simple measures such as quality door locks. That is PSNI’s own statement and the page does not give a source or date for it, so it is best treated as indicative. On keys, PSNI says never to give keys to workmen or tradesmen and to change locks if others may have copies; on selling a home, it says never to show people around alone and to ask the estate agent to send a representative with viewers.
After a burglary
PSNI says that anyone who has been burgled should call the police immediately on 999 and try to touch as little as possible to avoid disturbing forensic evidence, and that a local Crime Prevention Officer can give further advice. nidirect says that once a crime has been reported, the police will ask whether the person wishes their contact details to be passed to Victim Support NI, and that anyone who does not want their details passed on should tell the officer dealing with their case. Victim Support NI can be contacted directly before speaking to the police, and its help is free.
Common questions
Is entering an unlocked home still burglary?
The statute turns on entry as a trespasser, with the intent or later conduct described, not on whether a door was locked.
Does a caravan count?
Section 9(3) applies the burglary definition to an inhabited vehicle or vessel, so a lived-in caravan or boat can be within it.
The bottom line
In Northern Ireland burglary is governed by section 9 of the Theft Act (Northern Ireland) 1969, which covers entry as a trespasser with intent or theft or harm after entry, extends to inhabited vehicles and vessels, and carries a 14-year maximum, with life for aggravated burglary. PSNI recommends good locks and key discipline, and victims can report by 999 and be referred to Victim Support NI.
