Partially upheld complaint against the Governor of HMP Frankland

Complaint category:
Visits, calls & letters
Status:
Partially upheld
Month investigation completed:
September
Year investigation completed:
2025
The prisoner complained that a confidential access letter was opened in error. HMP Frankland apologised and offered compensation of £250, however, then rescinded the compensation offer and offered £50.
Recommendations/outcome:
There is no mandatory expectation for HMPPS to offer compensation for Rule 39/confidential access letters being opened in error. The process for authorising and issuing compensation was not followed when issuing the initial compensation offer and we did not consider the revised offer was unreasonable. However, HMP Frankland did not complete the actions required in national policy when confidential access correspondence is opened. We recommended that the Governor ensures all staff, including censors, are aware of the mandatory actions when confidential access correspondence is opened in error.

Upheld complaint against the Governor of HMP Lindholme

Complaint category:
Property
Status:
Upheld
Month investigation completed:
September
Year investigation completed:
2025
The prisoner complained that HMP Lindholme had lost their property following a cell clearance while they were in the segregation unit.
Recommendations/outcome:
While HMP Lindholme had completed the cell clearance process, they were unable to locate the prisoner’s missing property that was documented to have been in the cell when it was cleared. They had also used a local cell clearance certificate. Lindholme rejected a mediation offer. We recommended Lindholme use the cell clearance certificate annexed to national policy to avoid any future confusion and to compensate the prisoner for the loss of their property.

Partially upheld complaint against the Governor of HMP Swaleside

Complaint category:
Visits, calls & letters
Status:
Partially upheld
Month investigation completed:
September
Year investigation completed:
2025
The prisoner complained that legal mail he sent out of the UK was not posted. The prison did post it, but due to limitations with the franking machine they could not use a tracking method for international mail. We found the prison’s actions reasonable. However, we partially upheld the complaint as the response to the prisoner’s complaint did not specifically address his complaint.
Recommendations/outcome:
The prison has apologised to the complainant. We made the Governor aware of the shortcomings of the complaint response. We hold the view that this complaint should have been resolved by the prison without reference to IPCI.

Upheld complaint against the Governor of HMP Full Sutton

Complaint category:
Visits, calls & letters
Status:
Upheld
Month investigation completed:
August
Year investigation completed:
2025
The prisoner was unhappy with a comment made in his Cat A review paperwork and how his complaint about this was handled. The prisoner stated that a comment in his review suggested he had been involved with drugs. He also claimed that the prison had not followed correct complaint procedures.
Recommendations/outcome:
The comment made was factual, and therefore an apology for incorrect information was not required. On review of the complaint response, the prison did not provide an adequate and meaningful reply as required in the Prisoner Complaints Policy Framework. This aspect of the complaint was upheld. The Head of OMU apologised to the prisoner.

Partially upheld complaint against the Governor of HMP Askham Grange

Complaint category:
Categorisation, progression & release preparation
Status:
Partially upheld
Month investigation completed:
August
Year investigation completed:
2025
The prisoner complained that she had submitted a confidential access complaint form regarding her Home Detention Curfew (HDC) appeal, to the Prison Group Director (PGD) in April 2025. However, it had not been acknowledged or responded to. For completeness, IPCI also investigated the HDC appeal. The responses relating to the refusal of the prisoner's HDC application and appeal from Askham Grange were detailed and sufficient. Furthermore, there was no substantive new information provided to the PGD.
Recommendations/outcome:
The appeal against the HDC was not upheld. However, IPCI agreed that there was a long delay in the PGD responding to the prisoner's letter. The PGD explained the reasons for this delay which did not amount to a systemic issue with confidential complaint responses. An apology had already been given and therefore IPCI made no further recommendations.

Partially upheld complaint against the Governor of HMP High Down

Complaint category:
Administration
Status:
Partially upheld
Month investigation completed:
August
Year investigation completed:
2025
The prisoner complained about several issues regarding a prisoner assault and CCTV that were not upheld. However, they also complained that the COMP 1 response dismissed the main points of their complaint.
Recommendations/outcome:
Reminder that COMP responses need to be responded to in line with the requirements of the Prisoner Complaints Policy Framework. We hold the view that this complaint should clearly have been resolved by the prison without reference to IPCI.

Upheld complaint against the Governor of HMP Spring Hill

Complaint category:
Adjudication & IEP
Status:
Upheld
Month investigation completed:
August
Year investigation completed:
2025
The prisoner complained about the outcome of an adjudication.
Recommendations/outcome:
IPCI recommended quashing the adjudication because the prisoner denied the charge and there were no independent witnesses to the incident. IPCI expected the adjudicator would have viewed any and all available camera footage. The lack of witnesses meant it was one person’s word against another’s with no justification recorded for accepting the staff member’s version of events over that of the prisoner.

Partially upheld complaint against the Governor of HMP Buckley Hall

Complaint category:
Adjudication & IEP
Status:
Partially upheld
Month investigation completed:
August
Year investigation completed:
2025
The prisoner appealed about the outcome of an adjudication.
Recommendations/outcome:
IPCI recommended that the adjudication be quashed on two grounds. Firstly, the adjudicator had refused the attendance of two independent defence witnesses who we considered to be relevant to the prisoner’s defence as they contradicted what the reporting officer had said. We were also concerned that the reporting officer, who had been called to be a witness, had then been asked by the adjudicator to then contact another officer to provide a statement. This was directly in contravention of policy which says a witness who has completed his evidence must not have any opportunity to discuss the case with anyone waiting to give evidence.

Partially upheld complaint against the Governor of HMP Coldingley

Complaint category:
Property
Status:
Partially upheld
Month investigation completed:
August
Year investigation completed:
2025
The prisoner complained that he was not allowed a jacket in possession. The prison said that it was not allowed because of its dark colour, and this decision was in line with the local facilities list.
Recommendations/outcome:
We found that the prison was acting within its own policy when not allowing the jacket in possession. However, the prisoner complained about way his DIRF was handled, and we upheld this aspect of his complaint as we found procedural issues with the way it had been responded to, we raised this with the Governor.

Partially upheld complaint against the Governor of HMP Nottingham

Complaint category:
Categorisation, progression & release preparation
Status:
Partially upheld
Month investigation completed:
August
Year investigation completed:
2025
The prisoner complained that he was being refused Category C status and that he was not provided with a copy of the categorisation assessment within three days of the request. IPCI found that the outcome of the categorisation assessment was proportionate to the risks identified and therefore did not uphold this part of the complaint. However, we found no evidence that a copy of the assessment was provided to the prisoner within 3 days (as per Paragraph 4.1.3 of The Security Categorisation Framework) and therefore upheld this part of the complaint.
Recommendations/outcome:
IPCI suggested the prisoner resubmit the request for a copy of the assessment so staff can process in line with policy. The outcome letter was also sent to the Governor of HMP Nottingham so he was aware that we have made this point in relation to the provision of the categorisation assessment.
