Yes. Hartfield is a safe place to live. Its crime rate sits below the rest of Wealden. Violence and sexual offences make up a smaller share of the total than they do nationally. Vehicles and sheds make up a larger share than they do in most places. The risk here is mostly to your property, not to you.
Police figures for the year to May 2026 put Hartfield at roughly 50 recorded crimes per 1,000 people, about 10% below the Wealden average. That covers 131 recorded crimes across the year. It is a published rate, calculated on the statistical area's own population base, so a quick sum using the village headcount won't match it.
For comparison, Wealden as a whole ran at about 55 crimes per 1,000 over the same year. Wealden is already a quiet, rural district, so being below its average is a real result, not a technicality.
The setting explains a lot. Population density averages about 458 people per square kilometre, which in practice means houses spaced out along lanes, with fields between them. Unemployment is about 1% and about 3% of households are overcrowded. That's a village with space, work and room to spare, and it looks it.
What's recorded looks a bit different from the national pattern, though the totals are small enough that a handful of incidents can move any share by several points, so none of this is a fixed feature of the place. Violence and sexual offences, the broad legal category that includes common assault without injury, make up about 24% of Hartfield's crime against about 35% nationally, so it is less of the total here, not more. Anti-social behaviour is about 19% against 16% nationally, close enough to call similar. The differences are in property crime. Vehicle crime is about 17% of the local total against 5% nationally, criminal damage and arson about 12% against 7%, other theft about 11% against 7%, and burglary about 8% against 4%. In a village where most households run more than one car and most homes stand on their own plots, the cars and outbuildings are where crime tends to happen. A well-lit driveway and a decent lock on the shed are sensible spending here, not paranoia.
What happens after a crime is reported is a separate question from how much crime there is, and it is answered across the whole police force. Sussex Police charges a suspect in about 10% of cases, against about 12% nationally, which puts it 35th of 42 forces. About 48% of its cases are closed with no suspect identified. That is the honest answer to "will they catch whoever took the trailer", and the answer is that, about half the time, nobody finds out who did it. None of that makes Hartfield less safe. It makes prevention worth more than the follow-up.
Hartfield is one of the safer places to live in an already low-crime district. What little crime there is mostly targets things left outside, and your own security measures will do more about that than the police can.
