To acquire British citizenship you will usually need ILR/settled status, meet residence limits , pass B1 English and the Life in the UK Test, and satisfy the good character requirement.
Key takeaways
- Two main routes:
- 5-year route (s.6(1)) — ILR held 12 months before applying, residence limits (less than 450/90 days)
- 3-year route (s.6(2)) — if married to/with a civil partner who is British; ILR required at application, residence limits (less than 270/90 days)
- Be in the UK on the “anchor date”: You must have been physically present in the UK exactly 3 or 5 years before the application date.
- KOLL: B1 English + Life in the UK Test (exemptions apply).
- Good character matters: Immigration compliance, tax filings, criminality, and honesty are assessed.
- ILR first: Most applicants qualify for citizenship after securing Indefinite Leave to Remain (ILR).ritidh

What is British citizenship by naturalisation?
Naturalisation grants you full citizenship rights (including a British passport and the right to live and work in the UK without immigration restrictions). Most adults apply after a qualifying period of residence and ILR; some children may be registered instead of naturalised (different rules apply).

Common pitfalls (and how to avoid them)
- Wrong application date: Not being in the UK on the 3/5-year anchor date → we date-plan precisely.
- Excess absences: We assess discretion options and evidence (e.g., compelling work reasons).
- KOLL gaps: We time B1 English and Life in the UK early to avoid last-minute delays.
- Good character issues: We pre-review tax/immigration history and address risks transparently.
- Name/identity mismatches: We reconcile passports, BRP/eVisa, and certificates before filing.
