Beaconsfield is about as safe as the rest of Buckinghamshire, which makes it ordinary with a weakness for cars. Crime runs a whisker above the county rate. Violence takes a smaller share than it does nationally. Vehicle crime takes a much bigger one. The thing most at risk in this town has four wheels and lives on the drive.
Thames Valley Police recorded 1,139 crimes in Beaconsfield in the twelve months from June 2025 to May 2026, a published rate of about 67 per 1,000 residents. That puts the town roughly 3% above the Buckinghamshire average, close enough that a few busy weeks either way could have put it on the other side of the line. A full year of records smooths out any single bad weekend, so the figure is a fair description of an ordinary year.
Set side by side, the numbers are about 67 crimes per 1,000 people in Beaconsfield and about 65 across Buckinghamshire as a whole. The county figure has to cover High Wycombe and Aylesbury as well as the commuter towns, so this is a well-off town keeping pace with a county average that includes its bigger, busier neighbours.
The town itself is not a crowded place. It averages about 2,240 people per square kilometre, about 2% of working-age residents are unemployed, and about 2% of households are overcrowded. That is the texture of a roomy, employed, owner-occupied town, and none of it on its own explains the crime count either way.
The mix is where Beaconsfield looks like itself. Violence and sexual offences, a broad legal category that includes common assault without injury, make up about 29% of the town's recorded crime, against about 35% across England and Wales. Anti-social behaviour is about 10% here and 16% nationally. Vehicle crime runs the other way, at about 12% of the total against 5% nationally, and criminal damage and arson take about 10% against 7%. Shoplifting, at about 9% against 8%, and other theft, at about 8% against 7%, are both close to the national pattern. In a town with this much expensive metal parked on gravel, the over-represented crime is the one with a car in it. The police force's online street-level crime map is worth a look for the exact road, along with whether the house has a garage that holds a car as well as the bikes.
What happens next is a separate question from how much crime there is. Thames Valley Police, the force covering the whole of Buckinghamshire, Oxfordshire and Berkshire, charges a suspect in about 9% of cases, against about 12% nationally, which puts it 37th of 42 forces. About 37% of its cases are closed with no suspect identified. Those are force-wide figures and say nothing about how many crimes happen in Beaconsfield. They describe the chances of someone being caught once a crime has been reported, and for a stolen car those chances are not encouraging anywhere in the force area.
Beaconsfield's safety is middling: an unremarkable crime rate, less violence than the national pattern, and a car on the drive that is more interesting to thieves than the house behind it.
