Colney Heath is about as safe as the rest of St Albans district, a fraction better on paper and level in practice. The crime rate lands just under the district's. Unemployment is low. Homes are rarely crowded. Nothing here makes the village either a refuge or a worry.
Hertfordshire Constabulary recorded 390 crimes in the Colney Heath area in the year to May 2026, a published rate of about 78 per 1,000 residents. That is roughly 4% below the average for St Albans district. With totals this small, a handful of incidents either way would close the gap, so the village is level with its district and no better than that.
Set side by side, the district rate is about 81 crimes per 1,000 residents and Colney Heath's is about 78. Three points apart is the sort of difference a busy month erases.
The area has about 1,250 people per square kilometre on average, unemployment of about 2% and about 4% of homes overcrowded. A heath, one primary school and a conservation area at Sleapshyde make up most of the place, and none of them produces much of a crime report.
The mix needs reading with care, because with only 390 crimes a few incidents shift a share by several points. Violence and sexual offences, a broad legal category that includes assault without injury, made up about 30% of crimes here against about 35% nationally, so the area runs a little below the national pattern on the category that sounds worst. Anti-social behaviour was about 23% against 16% nationally, criminal damage and arson about 12% against 7%, vehicle crime about 9% against 5% and burglary about 6% against 4%. Other theft was about 5%, below the national 7%. The higher shares for damage, vehicle crime and burglary are worth knowing about, but one more year of figures could reshuffle them. To see where incidents cluster, look at the police street-level crime map for the roads around the house you are viewing, since the village-wide total cannot tell you that.
What follows a report is a separate question. Hertfordshire Constabulary charges a suspect in about 11% of cases, against about 12% nationally, which places it 23rd of 42 forces. About 40% of its cases close with no suspect identified. Those are force-wide figures covering the whole county, and they describe what happens after a crime, which a buyer should keep apart from how often crime happens here at all.
Safety in Colney Heath is middling. It runs much like St Albans district, with low numbers and a few categories running above the national pattern.
