In ILR applications, the residence periods, absence limits, and the Life in the UK test are widely understood. But the health and medical ILR UK requirements receive far less attention. Specifically, an outstanding NHS debt can result in refusal on suitability grounds, and gaps in IHS coverage may generate charges you were unaware of. Furthermore, applicants must understand how their IHS history affects their settlement application and what changes to their NHS access once the Home Office grants ILR.
- TB test: This is an entry clearance requirement (not an ILR requirement). If you entered the UK on a long-term visa from a listed country, you completed it at that stage. You do not need a new TB certificate for ILR.
- NHS debt: An outstanding NHS balance of £500 or more is grounds for ILR refusal. The Home Office does check for this, so clear any outstanding charges before you apply.
- Immigration Health Surcharge: You pay this with every visa renewal to cover NHS hospital access while on temporary leave. ILR applicants won’t have to pay IHS.
- NHS access after ILR: From the day the Home Office grants ILR, you qualify for free NHS hospital care as an ordinarily resident person, on the same terms as a British citizen, requiring no further surcharge.
This guide is for anyone approaching their ILR application who wants to understand the ILR UK requirements on the health and medical side in full detail: everything you need to know before submitting the ILR application.

Why the Home Office Has Health Requirements for ILR
The ILR UK requirements include health-related checks for three distinct reasons. Understanding each one separately makes the overall framework easier to follow.
1. To protect public health
Tuberculosis spreads through the air and remains common in many countries, even though the UK has brought it largely under control. Requiring a clear TB result before granting long-term entry is, therefore, how the UK maintains that position.
2. To clear any outstanding NHS debt
The NHS is publicly funded and keeps records of treatment charges. If you used NHS services during a period when your visa did not cover that access, the NHS will accordingly have raised a charge against your name. Before granting a settlement, the Home Office checks whether any such charges remain outstanding.
3. To confirm you contributed to healthcare costs
Every temporary visa holder pays the Immigration Health Surcharge upfront at each visa renewal. That fee consequently reimburses the NHS for treating people on time-limited leave.
When the Home Office grants ILR, those payments stop. Before granting settlement, the Home Office confirms that you maintained IHS payments throughout the period of temporary leave.
In practice, none of these ILR UK requirements presents a real problem for the majority of applicants. Most were addressed years before the ILR stage. However, each carries a specific rule, and missing any of them can delay the application or result in a refusal.
The Tuberculosis (TB) Test and ILR
Crucially, the TB test is an entry clearance requirement, not one of the ILR UK requirements addressed at the settlement stage. If you entered the UK on a long-term visa from a listed country, you will have completed the test as part of that original entry clearance application.
Do You Require a New TB Certificate for ILR?
No. Among the ILR UK requirements we covered, the TB test requires no action at the settlement stage. By the time you prepare your ILR application, you will have already satisfied this obligation.
NHS Debt and Suitability Checks
The Home Office assesses outstanding NHS debt under the suitability section of the application, not under a health heading. This placement is precisely why applicants frequently overlook it, and why it generates the highest rate of avoidable refusals among the ILR UK requirements covered in this guide.
Why an Outstanding NHS Balance Can Result in ILR Refusal
As part of the standard suitability check, the Home Office looks for any outstanding NHS debt. Consequently, even a charge you did not know existed can become a problem at this stage. If you owe £500 or more to the NHS at the time you apply, the Home Office has grounds to refuse the application.
That rule applies strictly regardless of whether the debt arose by mistake, you were unaware it existed, or you believe the NHS should never have raised the charge. Additionally, the Home Office does not distinguish between deliberate non-payment and genuine unawareness. You must clear the debt before you can proceed.
When NHS Debt Tends to Build Up
Outstanding charges most commonly arise from specific gaps in your immigration history. Addressing each of these periods is central to meeting this ILR UK requirement cleanly. The most common risk periods are:
- Before your IHS coverage started: any treatment received before your first long-term visa that included IHS coverage
- Between visas: any period when your leave had lapsed, and you were in the UK without active IHS cover
- Short-stay visas: time spent on a visitor visa or similar route, which does not include IHS
- Delayed billing: The NHS can sometimes raise charges weeks or months after the original appointment. These are the charges applicants are least likely to be aware of before applying.
How to Check and Clear NHS Debt Before You Apply
Step 1: Review your full immigration history
Review any period during which your visa did not include IHS cover. Those are the periods that carry the greatest risk of outstanding charges.
Step 2: Contact each relevant NHS trust directly
For any in-patient treatment, emergency care, or specialist appointment during those periods, contact the hospital trust and ask them to check your records for outstanding charges.
Step 3: Pay any outstanding charges in full
If a charge exists, settle it and retain the payment confirmation. Include that confirmation in your application bundle.
Step 4: Resolve any disputes in writing before you apply
If you believe the NHS applied a charge incorrectly, raise a formal dispute with the trust and obtain written confirmation of the outcome. The Home Office may identify an unresolved dispute, even a legitimate one, during the suitability check. Written documentation of the resolution carries as much weight as the payment itself. In either case, do not submit without resolving the issue first.
Completing these steps before submission is the most reliable way to satisfy this ILR UK requirement cleanly and avoid delays.
The Immigration Health Surcharge (IHS) and How It Connects to Your ILR
The Immigration Health Surcharge is the mandatory fee you pay upfront at every visa renewal to cover NHS hospital access during temporary leave. Understanding it is important because it connects to two of the ILR UK requirements: whether IHS gaps have generated outstanding NHS charges, and that the IHS ends the moment you apply for ILR.
Do ILR Applicants Pay the IHS?
No. Settlement applicants pay no IHS, and the Home Office requires no IHS payment at the ILR stage.
How IHS Gaps Connect to NHS Debt
If your IHS coverage had any gaps while you were in the UK, the NHS could have charged you for hospital treatment during those periods at 150% of the standard NHS rate. Those charges may, however, remain outstanding on your record.
This is the direct connection to the NHS debt requirement covered above. As we already suggested, review your IHS payment history before applying for ILR.
Life After ILR: What Changes for Your NHS Access
The final set of ILR UK requirements to understand your NHS entitlement after settlement. ILR entirely changes the legal basis on which you access NHS treatment.
Before settlement, your entitlement is temporary and conditional, tied to your visa status and IHS payments. After settlement, however, it becomes permanent and unconditional.
Healthcare Entitlements: Visa Holder vs. ILR Holder
Specifically, once the Home Office grants ILR, you automatically meet the “ordinarily resident” test, the legal threshold for free NHS hospital care in the UK, from the date of grant.
The table below compares your NHS access before and after the settlement. Each column reflects the legal basis, not a practical difference in day-to-day care:
NHS Access: Visa Holder vs ILR Holder
As a visa holder, your NHS access depends on maintaining a continuous, valid leave and paying the IHS fee in full at each renewal during your entire visa duration. As an ILR holder, neither of those conditions applies anymore. You access NHS care on exactly the same terms as a British citizen: no surcharge, no coverage conditions, and nothing tied to your immigration status.
Furthermore, any dependants who receive ILR alongside you gain this same entitlement on the same date. As a result, the entire household moves from conditional to permanent NHS access at the same point.
How A Y & J Solicitors Can Help
The health and medical ILR UK requirements span several distinct parts of your application history, which is precisely why applicants frequently overlook them:
- TB certificate: belongs to your entry clearance history, not the ILR application itself
- NHS debt: sits in the suitability section, separate from any health heading
- IHS payments: recorded across the fees section of every prior visa you held
- NHS entitlement: changes on the day the Home Office grants settlement
Most problems with the ILR UK requirements on the health side trace back to preparation gaps: an unidentified debt, an expired certificate, or a suitability issue identified only after submission.
