Eligibility under Section 6 (2) British Naturalisation

[Greta1407]

I am seeking some advice regarding my eligibility to apply for British citizenship by naturalisation, specifically under the provisions for applicants who are married to a British citizen.
I have legally resided in the UK since 3 March 2018 and was granted Indefinite Leave to Remain (ILR) on 7 February 2026. My ILR was obtained through the parent route rather than the spouse route.
I married a British citizen on 31 August 2022. We separated approximately a year after our marriage but remained legally married and have never divorced. We reconciled and resumed living together as a couple on 1 July 2026 and continue to live together.
My understanding is that a person who is married to a British citizen may apply for naturalisation as soon as they obtain ILR and does not need to have held ILR for 12 months. However, I would like clarification on whether this also applies in my circumstances, given that:
my ILR was obtained through the parent route rather than the spouse route; and
my spouse and I had a period of separation, although we remained legally married throughout and have now reconciled.
Could you please advise whether I can currently apply for naturalisation as the spouse of a British citizen without waiting until 7 February 2027, assuming I meet the residence, absence, good-character and other standard requirements?
I would particularly appreciate your view on whether the previous period of separation has any bearing on my eligibility under section 6(2) of the British Nationality Act 1981.
PS: I got married in the UK with a UK marriage certificate and she is the mother of my four children. I declared on my previous applications where I was married but separated. But we are now living together and have patched things up.

Many thanks, and I look forward to your advice.

Your route to ILR is irrelevant.

You simply need ILR and be married to a British citizen.

Everything else you have mentioned is irrelevant.

For example, I was separated from my then husband and we lived at different addresses and I still applied as spouse of British citizen as were were still legally married (married abroad). Application was successful within 5 weeks.

Don't over think things.
