    Areas of expertise

    what we are best at

    Immigration status requirement

    You must prove you are already settled in the UK before applying for citizenship. This means holding ILR, Settled Status.

    Key Points:

    ILR must be held for at least 12 months (unless applying as the spouse of a British citizen then immediate application is allowed).

    EU/EEA citizens may use Settled Status under the EU Settlement Scheme.

    Permanent Residence holders (EEA) must have converted to ILR/Settled Status after Brexit rules.

    Good character & other legal checks

    The Home Office tests whether you are of “good character” convictions, serious tax or immigration breaches, dishonesty or fraud can lead to refusal. Newer guidance (2025) also affects some categories (e.g. irregular entry policy).

    Key Points:

    Criminal convictions, recent immigration offences, or dishonesty may mean refusal.

    The Home Office has introduced stricter guidance in some areas (check if you have a complex history).

    Application process step by step

    Fees & typical processing time

    Fees have changed in recent months always check GOV.UK for the latest. The Home Office publishes updated fee tables (2025 changes noted).
