Five reports by independent immigration inspector published, covering asylum casework, administrative reviews, overstayers, contact with migrants, border refusals

No less than five new inspection reports by the Independent Chief Inspector of Borders and Immigration (ICIBI) were released yesterday. They cover inspection work carried out under John Tuckett, the current Independent Chief Inspector, and his predecessor, David Bolt.

All can be accessed from here on GOV.UK. The Home Office's responses to each report can be accessed from here.

• The ICIBI's 44-page An inspection of asylum casework (June 2025 – December 2025) can be downloaded here.

It finds that while the Home Office continued to reduce the backlog of asylum cases awaiting an initial decision during the inspection period, the quality of asylum decision-making declined significantly to what John Tuckett called an "unacceptable level".

Inspectors found that a strong focus on increasing productivity and reducing outstanding cases had contributed to lower decision quality, echoing concerns raised in a previous 2023 inspection. The report said this had wider implications for the asylum system, including potential impacts on appeals and operational workloads.

The ICIBI noted: "In a quality assurance initiative in August/September 2025, the Chief Casework Team sampled 47 of the 348 cases of grant decisions across all decision-making units (DMUs). Their findings showed that 37 (78.72%) contained insufficient evidence on which to make a decision and were therefore likely to be incorrect. Although this was only one limited exercise, if replicated across the system, these results suggested the quality of asylum decision making was not in a good state."

Inspectors identified three overarching issues affecting performance. The first was what the report described as "different versions of the truth" across the organisation, with conflicting perceptions among staff and managers regarding targets, interview processes, the balance between quality and productivity, and staff wellbeing.

The report said this was affecting morale and operational effectiveness, stating: "This level of disconnected thinking can be highly divisive and threaten the integrity of an organisation and its work. There is therefore an urgent need to change the cultural thinking across the organisation from an 'us and them' mindset to one of 'we are in this together', with all parts of the organisation recognising their responsibilities in bringing this about. Not to address this as a matter of urgency will only undermine and limit the effectiveness of any other actions that may be taken."

The second issue concerned quality assurance and decision-making standards. Quality targets for interviews and decisions had not been met across core decision-making units for more than two years. Factors cited included a management focus on productivity, accelerated recruitment campaigns, compressed training programmes, restrictive interview practices, and limited quality assurance processes.

The third issue was the absence of effective feedback and lessons-learned mechanisms at a strategic level. Inspectors found that opportunities to review performance, learn from outcomes and improve processes were often treated as secondary to productivity goals.

Turnover among decision-makers remained high. Although a recruitment and retention allowance introduced in 2022 initially reduced attrition from 45.51% to 26.17%, the ICIBI found turnover had increased again, with 882 asylum decision makers leaving between April 2024 and May 2025, representing an annual attrition rate of 42.2%. Decision makers who left the role had typically remained in post for only around 11 months, with most leaving the Civil Service altogether.

The report made three recommendations: improving organisational culture and collaboration, re-establishing quality as a core objective alongside productivity, and embedding stronger feedback and lessons-learned systems. The Home Office accepted all three recommendations in full, and implementation work is underway.

• The 131-page An inspection of Administrative Reviews (April 2025 to August 2025) can be downloaded here.

It finds significant delays, resource shortages and operational weaknesses in the administrative review system, undermining the purpose of the process as a mechanism for correcting immigration caseworking errors.

Administrative reviews were introduced in 2015 as a faster and less costly alternative to certain immigration appeal rights. However, the ICIBI found that by 2025 the system was operating far beyond its original 28-day service standard and "failing badly". Average processing times were 836 days for EU Settlement Scheme (EUSS) reviews, 207 days for international reviews and 185 days for in-country reviews.

Inspectors found that the Home Office's Administrative Review Unit (ARU) lacked the staffing, systems and prioritisation processes needed to manage its workload effectively. Applications were generally handled in date order, with limited triaging, meaning urgent cases and those involving safeguarding concerns were not always identified or prioritised. Inspectors said delays had caused hardship for applicants, including missed employment and study opportunities, difficulties accessing services, and impacts on physical and mental health.

The inspection also identified longstanding operational issues, including large backlogs, reliance on spreadsheet-based case management systems, limited management information, IT constraints, and difficulties securing additional resources. Inspectors found that around 90% of ARU decisions had exceeded the original 28-day service standard since 2021.

In contrast, administrative reviews of refusals of entry at the border, handled by the Border Force Administrative Review Hub, were generally completed within the 28-day target. However, inspectors raised concerns about decision quality, quality assurance arrangements and the handling of applicant data.

The report noted that some recommendations repeat concerns raised in previous inspections in 2016 and 2020, including calls for a full evaluation of the administrative review system and improvements to data, quality assurance and operational processes.

Seven recommendations are made by the ICIBI, including reducing delays, restoring a formal service standard, improving triaging and safeguarding procedures, strengthening quality assurance, upgrading IT systems, and improving data management. The Home Office accepted four recommendations in full and three in part, with implementation work underway.

• The 134-page An inspection of Home Office management of contact with migrants who are without leave to enter or remain (September 2024 – February 2025) can be downloaded here.

As John Tuckett explains, maintaining contact with migrants who are in the UK without leave to enter or remain is essential to progressing outstanding applications, encouraging individuals to regularise their status or leave the UK voluntarily, and, where appropriate, facilitating enforced removals.

Significant weaknesses are identified by the ICIBI's inspection in communication, data management and coordination across the immigration system. The report found that maintaining contact with this population, which numbers in the hundreds of thousands, is complicated by fragmented responsibilities across multiple Home Office business areas. Inspectors said a series of hand-offs between teams, poor communication, weaknesses in data sharing and outdated IT systems were limiting the department's ability to manage cases efficiently and effectively.

The inspection highlighted inconsistencies in immigration bail and reporting arrangements, alongside weaknesses in wider contact management. Inspectors found unreliable record keeping, inconsistent reporting practices and problems with the recording and updating of migrants' contact details, including within the asylum system.

Inspectors said there was evidence that senior officials had recognised many of these issues through the Asylum and Returns Transformation programme, but warned that the scale of the required reforms meant there was a risk that resources could be diverted before improvements were fully implemented.

The report made eight recommendations aimed at creating a more coordinated, end-to-end approach to contact management, including improvements to data quality, IT systems, immigration bail processes, electronic monitoring, and cross-department governance. The Home Office accepted seven recommendations in full and one in part, and said work to implement the recommendations is underway.

• The 98-page An inspection of overstayers (March – October 2025) can be downloaded here.

In it, the ICIBI finds that the Home Office lacks a single strategy or designated senior lead for tackling visa overstaying, with responsibility instead spread across multiple teams and directorates. This fragmented structure has contributed to gaps in oversight, inconsistent practices, and limited coordination across the migration and borders system.

The report highlights that overstaying is widely understood to be a significant factor in irregular migration, with many people who remain in the UK without permission having originally entered legally. However, the Home Office's ability to respond effectively is constrained by weaknesses in data, governance, and system integration.

Inspectors found that the Home Office is currently unable to produce a reliable estimate of the number of overstayers in the UK. Existing data systems are described as incomplete and inconsistent, while record-keeping practices vary across teams. A new system, "Counting In, Counting Out", is in development to improve tracking of arrivals and departures, but it is not expected to fully resolve gaps, particularly those involving movement through the Common Travel Area.

Enforcement activity against overstayers was found to be largely reactive and often overshadowed by other operational priorities. The report notes that overstaying is rarely treated as a standalone enforcement focus, with action more commonly taken when linked to other breaches such as illegal working.

The inspection also identified weaknesses in internal information sharing, including between visa-issuing teams and Immigration Enforcement. This reduces the department's ability to identify and act on cases where individuals may have overstayed or where risk indicators emerge after entry.

More positively, the ICIBI found the Home Office has begun work to strengthen its approach, including a recent re-prioritisation of overstaying and the introduction of updated policy tools. However, inspectors concluded that these changes are unlikely to be effective without clearer accountability, improved data quality, and a more coherent departmental strategy.

The report makes five recommendations aimed at improving governance, data systems, and operational coordination. Three have been accepted in full and two in part, with implementation already underway.

• Finally, the 38-page An inspection of refusals and cancellations of permission to enter the UK (September 2025 – February 2026) can be downloaded here.

It inspects Border Force's processes for refusing entry at the UK border at airports, seaports and overseas juxtaposed controls, and found that current arrangements do not operate as a coherent national system, with inconsistent practices and limited strategic oversight.

The report added: "Data collection is poor, with no standards for what is needed to assess performance or provide evidence for more strategic assessments. These weaknesses significantly limit effective assurance. There is no nationally co-ordinated approach to assuring refusals casework or the data that underpins it, resulting in a patchwork of local and regional activity with limited national oversight."

While much work is needed to ensure processes are truly fit for purpose, inspectors concluded that the system is not broken and they found no evidence of inappropriate refusals of entry.

The report said the current model remains rooted in traditional face-to-face border control, while future border operations are expected to rely increasingly on pre-travel checks, intelligence and digital systems. Inspectors found limited evidence that the future role of refusals activity has been fully defined within plans for a digitised border.

The report made two recommendations, calling on Border Force to establish a future operating model for refusals activity and, if face-to-face interventions remain necessary, to introduce a more consistent national framework covering governance, training, performance measures and data standards. Both recommendations were accepted in full by the Home Office.
