EU settled status and the 12-month rule: when can you apply for citizenship?
If you hold EU settled status, you can normally apply for British citizenship once you have held it for 12 months, because settled status is legally indefinite leave to remain under the EU Settlement Scheme. The wait is removed entirely if you are married to, or the civil partner of, a British citizen, and some applicants can start the clock earlier if they previously held permanent residence under the old EEA Regulations.
- Settled status is ILR granted under the EU Settlement Scheme, so it satisfies the settlement requirement for naturalisation
- Standard rule: 12 months free from immigration time restrictions before you apply, unless married to or in a civil partnership with a British citizen
- Home Office guidance lets you combine current settled status with EEA permanent residence you previously held to make up the 12 months
- Since 28 June 2022, caseworkers do not normally look behind a grant of ILR, so CSI gaps no longer usually block naturalisation
- Naturalisation costs £1,709 to apply, or £1,839 including the £130 ceremony fee, from 8 April 2026
How the 12-month rule works with settled status
GOV.UK describes settled status as indefinite leave to remain under the EU Settlement Scheme, and treats it exactly like any other grant of ILR for naturalisation purposes. For the standard 5-year route, you must be free from immigration time restrictions on the date you apply and for the 12 months before it. In practice, that means most people count 12 months from the date on their settled status decision letter.
While you work out your eligibility, it's worth knowing how you'd do on the test itself — try a free Life in the UK mock test, no sign-up needed.
There is one clean exemption. GOV.UK states plainly that you do not need to wait 12 months to apply if you are married to a British citizen, and the same applies to civil partners, who qualify under the 3-year route instead.
On the standard route the other numbers still apply: 5 years' residence, no more than 450 days outside the UK in that period and no more than 90 days in the final 12 months. Our guide to counting absences for naturalisation walks through worked examples.
The permanent residence nuance: you may qualify sooner than you think
Here is the detail many people miss. Before the EU Settlement Scheme existed, EEA nationals could acquire permanent residence under the EEA Regulations, usually automatically after 5 years of qualifying activity, with or without a document confirming it.
The Home Office nationality guidance on naturalisation by discretion says that EUSS settled status holders "can show that they have been free from immigration time restrictions for 12 months before applying using a combination of current EUSS leave and permanent residence they previously held under the EEA Regulations". In other words, if you held EEA permanent residence before switching to settled status, caseworkers can treat your settlement as starting earlier than your EUSS grant date, which may mean you can apply straight away rather than waiting a further year.
Be conservative here. The cleanest evidence is a permanent residence document or card issued before you moved to the EUSS. Arguing that you had acquired permanent residence automatically, with no document, means proving 5 years of qualifying activity under the old rules, and the caseworker will assess that evidence. If your settled status grant is already close to 12 months old, waiting is usually simpler and safer than building a permanent residence argument.
EEA permanent residence itself died on 30 June 2021. The guidance is explicit that anyone who held permanent residence but did not apply to the EUSS before the end of the grace period "will have lost their EEA residential rights" and is no longer free from immigration time restrictions. Old PR only helps as history combined with current settled status. On its own it is not a live immigration status and cannot support an application.
CSI and lawful residence: the 2022 change
For years, EU citizens who had been students or self-sufficient faced refusals over comprehensive sickness insurance (CSI), because time without it did not count as lawful residence under the British Nationality Act 1981.
Two things changed in 2022. First, the Court of Justice held in VI v HM Revenue and Customs (C-247/20, 10 March 2022) that a person affiliated to the NHS had CSI, and the Home Office guidance now says a person who was ordinarily resident in the UK "will be considered to have held CSI". Second, following the Nationality and Borders Act 2022, the guidance instructs caseworkers that where an applicant holds ILR, including settled status, they "do not need to look back to see if they were here lawfully" and do not need to ask whether an EEA national had CSI. The guidance notes this applies in most cases, with enquiries reserved for exceptional situations such as fraud coming to light. So a historic CSI gap should not normally block your application, though the position sits in caseworker guidance rather than the statute itself.
Timing your application and what else you need
Once your 12 months are up (or immediately, if your spouse or civil partner is British), you still need to pass the Life in the UK test, meet the English language requirement, satisfy good character checks and pay the fee, which is £1,709 to apply or £1,839 including the citizenship ceremony from 8 April 2026. The Life in the UK test certificate never expires, so many people sit it during the waiting year. For a fuller look at what applies from day one of settled status, see can you apply for citizenship straight after settled status.
Apply too early without a valid permanent residence argument and the application can be refused with no refund, so check your dates carefully before you pay.
