ILR Refusal Reasons UK: Why Applications Get Rejected and What to Do

A refused ILR application costs you £3,226, your immigration status becomes uncertain, and you may need to apply for a further extension to remain in the UK while you address the problem. In most cases, refusals are preventable. They rarely occur because someone doesn't qualify — they occur because an application was submitted with the wrong documents, incorrect calculations, or issues the applicant didn't know about.

The Home Office does not publish a single aggregate ILR refusal rate, but analysis of Home Office data suggests that over 5% of settlement applications result in refusal or an invalid decision — a meaningful proportion given the volume of applications. Work-based routes have a lower refusal rate than family or long residence routes, but no route is risk-free.

The Most Common Refusal Grounds

1. Absence Exceeding 180 Days in a Rolling 12-Month Window

This is the most frequent basis for refusal on technical grounds. Applicants calculate their total absences over their qualifying period and find the number acceptable — but don't check every possible rolling 12-month window. A caseworker who finds a window where absences exceeded 180 days has a clear basis for refusal.

The fix is to audit your travel history before applying. Request your Border Force data through a Subject Access Request if you're not certain of every trip.

2. Employer Letter Not Meeting Home Office Standards

Missing the "foreseeable future" statement, lacking the SOC code, or not including the current salary makes the employer letter non-compliant. Caseworkers are trained to look for specific language, and a vague or generic letter will prompt a query or refusal.

3. Applying Too Early — The 28-Day Rule

An application submitted before the 28-day window opens is automatically refused as "invalid." The 28-day window opens 28 days before the 5-year or 10-year anniversary of the date from which your qualifying period runs. Applying even one day before this window is an automatic refusal with no refund.

The qualifying date calculation is non-intuitive. For some applicants, it's the date the visa was granted; for others, it's the date of entry to the UK. Getting this calculation wrong is surprisingly common.

4. Salary Below Threshold

For Skilled Worker applicants, falling below the applicable salary threshold — whether due to a recent pay change, unpaid leave, or the new per-pay-period rule — results in refusal. The per-pay-period rule introduced in April 2026 means a single month's payslip below threshold can be a problem, even if the annual average was fine.

5. NHS Debt

An outstanding NHS debt of £500 or more (for debts accrued after 2016) is a mandatory ground for refusal. Applicants who have used NHS services and have outstanding bills — including unpaid hospital charges from years ago — need to check and clear these before applying. The Home Office has access to NHS records.

6. Criminal Record

A custodial sentence of 12 months or more results in a mandatory refusal. Non-custodial sentences, conditional discharges, or cautions within the last 24 months are discretionary grounds for refusal — the caseworker assesses these against the broader application. Any caution or conviction, however minor, must be declared. Failure to declare is treated as deception.

7. HMRC Discrepancies (Paragraph 322(5))

The Home Office compares income declared for visa purposes against income declared to HMRC for tax. If there's a discrepancy — you stated £40,000 on your extension application but HMRC records show self-assessment or payroll income that doesn't match — this can be treated as dishonesty and used as a character ground for refusal.

This is particularly relevant for applicants who received tax refunds due to overpaid PAYE, who had income from more than one source, or who changed employers during the qualifying period. Request your HMRC records and check them against your visa applications before you submit for ILR.

8. "Duties Drift" for Skilled Worker Applicants

If the duties you currently perform no longer align with the SOC code on your Certificate of Sponsorship, the Home Office may determine your sponsorship is not genuine. This is increasingly scrutinised at settlement stage. If your role has evolved substantially over five years, ensure your employer has issued an updated COS or that the letter explains the continuity of the SOC code.

9. Incorrect Form

Filing SET(O) when SET(M) is required, or vice versa, makes the application invalid. It's processed as an invalid application, not as a wrong-route application, and the fee is not refunded.

10. Good Character Failures Beyond Criminal Records

The "Good Character" requirement also covers civil matters: outstanding civil debts, contraventions of UK immigration law (including visa overstays, even historical ones), and failure to cooperate with the Home Office in previous applications. A visa overstay of more than six months at any point can add years to the qualifying period under the Earned Settlement penalty framework.

If Your Application Is Refused

You have 14 days from the date of refusal to seek an Administrative Review (AR) if you are in the UK. The AR fee is £80. The AR is used when you believe the caseworker made a factual error or missed a document you submitted. New evidence cannot be introduced in an AR — it reviews the original decision based on the original evidence.

If the refusal is based on legal issues or Home Office conduct rather than factual error, Judicial Review in the High Court is an option, but it is slow and expensive.

While a challenge is pending, Section 3C leave extends your previous visa conditions — you retain your right to work and remain in the UK until the challenge is resolved. Do not leave the UK once a challenge is in progress without confirming your status permits re-entry.

The UK ILR Settlement Guide includes a pre-submission refusal risk checklist — a self-audit process covering each of the grounds above — so you can identify and resolve problems before the Home Office does.
