Yes, Sunbury is a fairly safe place, and safer than the borough around it. Crime runs a little below the Spelthorne average. Unemployment is low. Crowded homes are rare. The crime that does happen is much the same mix as everywhere else in England.
In the year to May 2026, police recorded 2,656 crimes in Sunbury, a published rate of about 83 for every 1,000 residents. That's roughly 9% below the average for Spelthorne.
The borough's own published rate over the same twelve months was about 91 crimes per 1,000 residents. Sunbury comes out at about 83, below Spelthorne as a whole but not by much. The gap is real but modest. Anyone who describes Sunbury as crime-free is using a stronger word than the police figures support.
Sunbury is fairly built-up for a town on the edge of Surrey. Averaged across its neighbourhoods, it has about 4,800 people per square kilometre. Unemployment is about 3%, and about 5% of households are overcrowded. That's a town where most people have jobs and enough room at home, and the crime figures look like it.
Violence and sexual offences are the biggest category, at 37% of the total against 35% nationally. That category is the largest almost everywhere, and it includes common assault where nobody was hurt. Anti-social behaviour is about 15%, a little below the national 16%. Public order offences are about 10%, against 7% across England and Wales, and that's the only category clearly above the national share. Criminal damage and arson make up 8% (7% nationally), other theft 7% (also 7% nationally), and vehicle crime about 6% (5% nationally). For most of the list, Sunbury looks like an ordinary English town. Admiral Hawke, who lived here, spent much of 1758 blockading Brest. Public order offences in Sunbury today are on a much smaller scale.
If you report a crime, the outcome depends on Surrey Police, the force for the whole county. Over the year to May 2026, it charged a suspect in about 11% of cases, against about 12% nationally, which puts it 30th of 42 forces. About 36% of its cases were closed with nobody identified as a suspect. Those are figures for the whole county force, and they say nothing about how safe Sunbury itself is. What they do tell you is how likely a case is to be solved if you're the victim, and that figure is less reassuring than the crime rate.
Sunbury is safer than average, a little calmer than Spelthorne as a whole. Crime is low enough that most buyers have bigger things to worry about.
