Wigan prison's performance rating has improved since the pandemic

But there is still plenty of room for improvement as its operations are still “of concern” to watchdogs.

The Prison Reform Trust said the latest reports on prison performance show the system is experiencing a "perfect storm" of rising prison population and poor working conditions.

Figures from the Ministry of Justice's prison performance report give ratings based on four main priority areas, security, training, drug and alcohol addictions, and readjustment to society.

The report shows Hindley Prison received a score of 54 per cent for the year to March 2023, meaning it had a "performance of concern" rating.

That was a small improvement from 53 per cent in 2019-20, the last year ratings were handed out.

Across England and Wales, only 13 of the 119 prisons evaluated were awarded the "outstanding performance" rating, a significant drop compared with the performance in 2019-20, where 19 prisons had achieved the top-tier recognition.

It also showed there was a slight increase in the number of prisons rated as a "serious concern" compared with the previous year. Nine prisons fell into this category, a rise of two from in the previous evaluation.

A Prison Service spokesperson said: "The latest figures show that over half of all prisons are performing well and, where there are issues, we are providing intensive support for those jails to drive long-term improvements, recruit extra staff, bolster security and boost training and work opportunities for prisoners so we can better protect the public."

They added they are working on the "biggest prison expansion" in over a century by building 20,000 new prison places.

Separate data from the Home Office found the rate of prisoners living in overcrowded conditions increased from 21 per cent in 2021-22, to 23 per cent in the most recent year to March.

About 20 per cent of the estimated 583 prisoners in Hindley were in crowded accommodation.

Pia Sinha, chief executive of the Prison Reform Trust, said the latest figures show the prison system is "chronically overburdened".

She added: "Prisons are experiencing a perfect storm of a rapidly rising prison population with nowhere to put them, and working conditions which are driving staff away in droves.

"Faced with escalating violence, self-harm, appalling living conditions and prisoners left with nothing to do all day – the human cost of this crisis is shameful."
