Who checks the immigration system
Six independent bodies scrutinise different parts of it — the statistics regulator, the prisons inspectorate, the statutory monitoring boards, the ombudsman, coroners and select committees. This is what each has on the record.
Scrutiny is only worth anything if somebody answers it. Where the record shows whether a report was responded to, that is published here too.
Parliament: what committees concluded, and whether anyone answered
A select committee reports; the government is expected to respond, and the parliamentary record carries the deadline. Both are published, so both are here. A committee's conclusions are the committee's — this site republishes that a report exists and what state its response is in, not a verdict on either.

Coroners: formal reports to the Home Office
Where a coroner believes action should be taken to prevent future deaths, they must report to whoever could take it, under Schedule 5 of the Coroners and Justice Act 2009. The recipient must respond within 56 days. Of 143 such reports naming the Home Office, 4 were sent to the department and concern the immigration system.

The ombudsman: deaths investigated in the detention estate
The Prisons and Probation Ombudsman independently investigates deaths of people detained under immigration powers. Every immigration establishment in its own index is listed below, including those with no published investigation — an absence is a fact, not a gap.
| Establishment | Published investigations |
|---|---|
| Brook House Immigration Removal Centre | 2 |
| Colnbrook Immigration Removal Centre | 1 |
| Harmondsworth Immigration Removal Centre | 1 |
| Derwentside Immigration Removal Centre | 0 |
| Dungavel House Immigration Removal Centre | 0 |
| Morton Hall Immigration Removal Centre | 0 |
| The Verne Immigration Removal Centre | 0 |
| Tinsley House Immigration Removal Centre | 0 |
| Yarl's Wood Immigration Removal Centre | 0 |
3 of 9 establishments have a published investigation; 6 have none. The most recent was published 12 September 2025 (Harmondsworth Immigration Removal Centre) — read it ↗.
They publish that an independent body formally reported, to whom, about where, and when — and they link the report so it can be read in full. They do not publish the name of anyone who died, the circumstances, the medical cause or the inquest conclusion. All of that is in the linked documents, where it belongs, and none of it belongs in a table on this site.
The accountability fact is that the state was formally told something must change. A person who died is not an exhibit in that argument.
Inspection and monitoring
HM Inspectorate of Prisons inspects immigration detention; a statutory Independent Monitoring Board sits in every removal centre and short-term holding facility and reports annually, with the Home Office publishing a written response to each. The full lists are on the enforcement page; the most recent of each is below.

4 of the documents listed here are the department's own written response to a board's report. Scrutiny that is answered is the thing this page is measuring, and monitoring boards are the one part of the estate where the reply is published alongside the report.
The statistics regulator
The Office for Statistics Regulation assesses whether the department's figures meet the Code of Practice for Statistics — including, in 2026, finding that an unscheduled release of an internal asylum hotel figure breached it. Its correspondence is republished in full on the sources page.
