Is Longfield, New Ash Green and Hartley a safe area?

For anyone buying or renting in Longfield, New Ash Green and Hartley.

Yes, about as safe as the rest of the Sevenoaks district, and no safer. Crime runs level with the district average. Anti-social behaviour is more common than it is nationally. Violence is well below the national share. Most of the trouble here is the kind that ends in a strongly worded letter.

In the year from June 2025 to May 2026, police recorded 1,414 crimes in the area. The published crime rate was about 65 per 1,000 residents. That is roughly level with the local-authority figure. The area is not a hotspot and not a sanctuary either. It is ordinary, and for many buyers ordinary is exactly what they are paying for.

The Sevenoaks district as a whole runs at about 64 crimes per 1,000 residents, against about 65 here. A one-point gap is too small to mean anything. An estate agent who calls the area "exceptionally safe" is selling you the district's average and calling it a feature.

The texture behind those numbers is suburban and comfortable. Population density averages about 3,100 people per square kilometre, which means homes with gardens and space between them rather than tower blocks. Unemployment is about 2% and overcrowding about 2%. These are streets where neighbours notice an unfamiliar van. The net curtains effectively do the work of a neighbourhood watch.

The mix of crime says more than the total. Anti-social behaviour makes up about 26% of recorded crime, against 16% nationally, which is the clearest local difference. Violence and sexual offences also account for about 26%, against 35% nationally. That category covers everything from common assault without injury upwards, and it is the largest category almost everywhere, so a share well below the national figure is a good sign. Shoplifting is about 12% against 8% nationally, and criminal damage and arson about 10% against 7%. Other theft is about 7%, close to the national share, and vehicle crime about 6% against 5%, also close. In short, this area has more people being a nuisance than people doing real harm.

After a report is made, Kent Police charges a suspect in about 16% of cases, against about 12% nationally. That puts it sixth of the 42 forces in England and Wales. It is a force-wide figure covering the whole county, not a measure of these villages, and it says nothing about how likely a crime is to happen here. About 36% of cases across the force are closed with no suspect identified. That is the honest answer to whoever asks whether the police will catch the person who kicked the wing mirror off their car.

Safety here is middling: level with the district, lighter than average on violence and heavier on anti-social behaviour. The things most likely to spoil your evening are noise and vandalism, not danger.
