A new law mandating the suspension of most prison sentences of 12 months or less has come into force, in a move ministers say is aimed at easing overcrowding and reducing reoffending. Under the Sentencing Act 2026, courts must now impose suspended sentences for shorter custodial terms unless specific exceptions apply, meaning offenders will typically serve their punishment in the community rather than behind bars.

Speaking on BBC Radio 4 Today, David Ford, chair of the Magistrates' Association, said the change represents a significant shift in sentencing practice. Mr Ford said: "As from today, we must suspend unless one of those exceptions applies. In the past, we might normally have sent someone to a 12-month custodial sentence. That will now be suspended."

Mr Ford stressed that courts still retain the power to impose immediate custody in certain circumstances. These include cases where offenders are already in prison, where they are being re-sentenced for breaching an existing order, or where there is a significant risk of harm to others, particularly in domestic abuse cases.

The reform is the centrepiece of a wider overhaul designed to prevent what the Government has described as a potential collapse of the prison system, with jails in England and Wales facing severe overcrowding pressures.

Instead of short custodial terms, courts will rely more heavily on community orders. These can include unpaid work of up to 300 hours, curfews lasting up to two years, electronic tagging, and exclusion zones preventing offenders from entering certain areas.

The Act also introduces new "Income Reduction Orders", allowing authorities to dock offenders' wages, alongside an expanded use of GPS monitoring.

Mr Ford acknowledged concerns that the probation system is not sufficiently resourced to cope with the increased demand.

Mr Ford said: "We need the tools to do the job. The purpose of sentencing is to punish offenders, reduce crime, and rehabilitate. If we're not going to be sending somebody to custody, we need a meaningful alternative."

Mr Ford added that while magistrates' experience with probation staff is positive, there are ongoing questions about capacity. Mr Ford said: "Are there enough probation officers? Are they able to do the reports quickly enough? Those are the concerns we have."

The Government has pledged £700 million in additional funding for probation services as part of the reforms, but critics have warned that existing pressures could undermine the effectiveness of community sentencing.

Mr Ford also pushed back against suggestions that non-custodial sentences are lenient. Mr Ford said: "A community option is not a 'soft' option," pointing to punitive elements such as enforced labour, restrictions on movement, and long-term supervision.

The shift reflects longstanding evidence that short prison sentences are less effective at preventing reoffending than community-based interventions. Offenders serving brief custodial terms often leave prison without access to education, employment support or rehabilitation programmes.

Alongside the changes for lower-level offenders, the Act introduces stricter rules for those already in custody, including an "earned progression model" which removes automatic early release for prisoners who fail to comply with behaviour expectations.

The reforms took effect immediately on Monday, marking one of the most significant changes to sentencing policy in recent years.
