The 12-month deportation threshold and ILR holders: what HC 259 changed
Since 3 August 2026, the Immigration Rules have made clear that a suspended sentence of at least 12 months can trigger the UK's deportation framework in the same way as a 12-month custodial sentence, where the conviction happened on or after 22 March 2026. The change came in Statement of Changes HC 259, laid on 9 July 2026, and it matters to people with indefinite leave to remain (ILR) because a deportation order invalidates ILR entirely. The 12-month custodial threshold itself is not new; what is new is that being spared prison no longer means being spared deportation consideration.
- HC 259 was laid on 9 July 2026; the deportation-related changes took effect on 3 August 2026
- Part 13 of the Immigration Rules now applies the deportation and Article 8 framework to a suspended sentence of at least 12 months, where the person was convicted on or after 22 March 2026
- This aligns the Rules with the Sentencing Act 2026, which took effect on 22 March 2026
- The UK Borders Act 2007 already places a duty on the Home Secretary to deport a foreign national sentenced to at least 12 months' imprisonment, subject to exceptions
- A deportation order invalidates any leave, including ILR (Immigration Act 1971, section 5(1))
- None of this applies to British or Irish citizens
What HC 259 actually changed
HC 259 amended Part 13 of the Immigration Rules, the part that governs deportation decisions and how the Article 8 (family and private life) framework is applied. The amended wording covers a foreign national who has been convicted of an offence for which they have "received a custodial sentence of at least 12 months or received a suspended sentence of at least 12 months where a person has been convicted on or after 22 March 2026".
Where that applies, the Rules say the public interest requires deportation unless an exception is met: the private life exception, the family life exception, or "very compelling circumstances" beyond those. HC 259 also added the same suspended-sentence wording to criminality grounds elsewhere in the Rules, such as the Electronic Travel Authorisation and Child Student provisions, to keep refusal and cancellation grounds consistent.
The explanatory memorandum is explicit about why. The Sentencing Act 2026, in force from 22 March 2026, changed sentencing practice so that more sentences are suspended rather than served in custody. Without a matching change, someone whose 12-month sentence was suspended would have fallen outside the deportation framework on a technicality. HC 259 closes that gap.
How this fits with automatic deportation under the UK Borders Act 2007
The headline number has not moved. Section 32 of the UK Borders Act 2007 defines a "foreign criminal" as someone who is not a British or Irish citizen, is convicted in the UK, and is "sentenced to a period of imprisonment of at least 12 months". The Secretary of State "must" then make a deportation order, subject to the exceptions in section 33 (which include breach of the Human Rights or Refugee Conventions).
Historically, section 38 of that Act excluded suspended sentences unless a court later activated them. The Sentencing Act 2026 amended that interpretation provision with effect from 22 March 2026, which is exactly why HC 259 uses that conviction date as its cut-off. For earlier convictions, a suspended sentence generally still only counts if it is activated.
For convictions on or after 22 March 2026, a suspended sentence of 12 months or more is not a "let-off" in immigration terms. If you have ILR and are facing criminal proceedings, tell your defence solicitor about your immigration status and get specialist immigration advice before sentencing. The immigration consequences can be more serious than the sentence itself.
Deportation, revocation and refusal grounds are not the same thing
Three separate mechanisms get mixed up in discussions of this change.
Deportation is removal under a deportation order. Under section 5(1) of the Immigration Act 1971, a deportation order "shall invalidate any leave to enter or remain", which includes indefinite leave. This is the mechanism that directly ends ILR after serious criminality.
Revocation of ILR is a separate power, used for example where status was obtained by deception or where someone is liable to deportation but cannot be deported. We cover the full picture in can ILR be revoked or lost.
Refusal grounds apply when you make an application for entry clearance or permission. Home Office criminality guidance was updated on 26 March 2026 to mandate refusal or cancellation where a person has received a suspended sentence of 12 months or more. For ILR holders, the common pressure point is a later application, such as applying for British citizenship with a criminal record, where the good character requirement applies its own, stricter thresholds.
HC 259 did not create a new power to strip ILR over old convictions, and it did not lower the 12-month custodial threshold, which dates from 2007. The change is about suspended sentences for convictions on or after 22 March 2026.
What ILR holders should take from this
ILR is stable, but it is not unconditional. It does not protect you from deportation the way British citizenship does, and that gap has just become more visible: a conviction that once ended in a suspended sentence with no immigration consequences can now put your entire status at risk. That is a genuine reason many long-term residents complete the journey to citizenship, which means passing the Life in the UK test and meeting the good character requirement while your record is clean.
If you are already facing proceedings, none of this is automatic in practice: the Article 8 and section 33 exceptions still apply, and specialist legal advice is essential. This article is general information, not legal advice.
