About as safe as the rest of Sutton, and a fraction safer. Crime runs slightly below the borough rate. The mix of offences is almost identical to the national one. The police force covering it charges fewer suspects than most. Belmont is an ordinary London suburb on crime, which for a London suburb is a respectable result.
Police recorded 3,323 crimes in Belmont in the year to May 2026, a published rate of about 76 per 1,000 residents, roughly 4% below the Sutton average. The rate uses its own population base for the small statistical areas involved, so it should be read as published. Belmont's most famous secure building is HM Prison High Down, on the site of the old Banstead Asylum next door, and its residents are among the few people in the area nobody needs to lock a door against.
Across the London Borough of Sutton as a whole, the published rate for the same year is about 79 crimes per 1,000 residents. Belmont's 76 sits a few points under it, close enough that a handful of busy months could close the gap.
Belmont packs in about 7,860 people per square kilometre on average across its neighbourhoods, a figure that comes from all those flats. Unemployment at the 2021 Census was about 3% and about 7% of households were overcrowded. These describe what Belmont is like as a place to live, and none of them on its own explains the crime rate. A dense suburb of flats near a station and a short high street generates reports simply because there are more people and more front doors in a small space. Check the police's own street-level crime map for the exact road and the streets around it, particularly near Station Road, where the shops and the station bring the most people through.
The breakdown by type is close to the national pattern. Violence and sexual offences, a broad legal grouping that runs from serious assault down to common assault without injury, made up about 35% of Belmont's recorded crime, exactly the share for England and Wales. Anti-social behaviour was about 16%, the same as nationally. Public order offences were about 8% against 7% nationally, other theft about 6% against 7%, vehicle crime about 6% against 5%, and criminal damage and arson about 6% against 7%. No category stands out. Belmont's crime has no speciality, which is about the best compliment a crime breakdown can pay.
What happens after a report is a separate question, answered at force level. The Metropolitan Police Service charged a suspect in about 10% of cases over the year to May 2026, against about 12% across England and Wales, ranking 33rd of 42 forces. About 53% of its cases closed with no suspect identified. Those figures cover the whole of London, and they describe the force's results, with no bearing on how safe Belmont's streets are. A Belmont burglary goes into the same London-wide queue as one in any other borough.
On safety, Belmont is middling. It is a fraction calmer than Sutton overall, has an ordinary mix of offences, and relies on a police force whose clear-up record is weaker than the national figure.
