How long does it take to become a British citizen? £1,709 fee and the schedule from submission to swearing-in

JustiScript

The naturalization application fee increased to £1,709 on April 8th.

Plus the £130 oath fee that must be paid when submitting, £1,839 will be deducted from your account at the moment you click submit. Compared to the previous tier of £1,605, it has increased by £104. This number itself is not enough to keep someone awake at night. The tough part is the period after the money is paid, when there's no progress bar: the system does not show which step has been reached, and customer service only repeats "there will be a result within six months."

The decision on how to proceed during this period is not determined by that statement of service standards on the UKVI website, but rather by section 42 of the British Nationality Act 1981. If we break down that section sentence by sentence, the shape of the entire timeline will become apparent.

The cost of British naturalization: £1,839 is deducted in full on the day of submission.

First, even out the accounts. The following table shows all official fees from the exam to the oath, excluding the agency fees.

Link Fee Time
Life in the UK Test £50 Schedule by test center, advance booking required
Submit Form AN £1,709 + £130 Pay in full on the same day
Biometric Information Collection Standard Appointment Does Not Charge Submit and Follow the Center Schedule
Trial and Decision Optional Expedited Service £500 Standard processing within 6 months; Expedited processing within 30 working days
Oath Ceremony Included in £130 Must be completed within 3 months after receiving the invitation

The £130 is the most easily misunderstood. It is not cash paid on the day of the oath, but rather bundled with the application fee and deducted together on the submission day. If the application is rejected or withdrawn before the oath, the £130 will be refunded; £1,709 is non-refundable. The actual amount put up as a deposit is only £1,709, the remaining amount is part of the refundable portion - think clearly about this before deciding whether the documents are complete enough to proceed with submission.

The threshold conditions remain the same: ILR, 12 months on hand, no more than 90 days absence in the last 12 months, and total absence of no more than 450 days over five years, Life in the UK plus B1. These points have been written about so much, no need to repeat. The reminder is that absence days are calculated based on passport stamps and boarding records, not memory. Those stuck around 80 days must recheck these five years before submitting. This account's 永居计算器 can count these days accurately, just click the bottom menu bar to use it.

Article 42 consists of only one sentence, yet it controls the final paragraph.

"A certificate of naturalisation as a British citizen shall not be granted... to a person of full age unless he has made the relevant citizenship oath and pledge specified in Schedule 5 at a citizenship ceremony."
——British Nationality Act 1981, s.42(2)

Look one sentence at a time.

"shall not be granted": The certificate is not issued before the oath. The approval letter you received only informs you that you can go to take the oath; legally, it gives you no status. The real-world correspondence is straightforward - if you apply for a British passport with the approval letter, it will be rejected.

"A person of full age": This restriction applies only to those over 18. For families applying together, the certificates of minor children will be directly sent to the home, and the parents have to wait until the parliament allocates a position.

"at a citizenship ceremony": The oath must be made publicly during the ceremony. The date is arranged by the local council where you live, UKVI has nothing to do with it. The speed of scheduling completely depends on the density of sessions of that council in the season, and the result can be different for the same person if they move to a different district.

The three-month period on the invitation letter comes from the 2003 British Nationality (General) Regulations. If you do not take the oath within this window, this approval will be void; the Home Secretary can indeed extend or exempt under s.42(5), (6) in exceptional circumstances, but that is a discretion, not a right, and the stance that even one day's difference is not acceptable holds here. Therefore, the first thing to do after receiving the approval letter is to contact the council on the same day to book a slot, especially for those with long-distance travel plans in the next three months.

There is another consequence that is rarely mentioned: the date of naturalization stated on the certificate is the day of the oath taken on , not the date of the approval letter. It does not affect families within the UK, as children of parents who are already settled in the UK are automatically considered settled. However, if a child is born outside the UK and the time falls between the approval and the oath, the parents were not legally British citizens at that time, so the child cannot obtain British citizenship by descent. There is usually a gap of several weeks to months between approval and the oath, and for families who often return to their home country near the end of pregnancy, this time difference needs to be carefully scheduled.

On July 6th this year, UKVI introduced a £500 priority service for citizenship and registration applications, which guarantees a decision within 30 working days from the day of biometric information collection. Applications already submitted cannot be added later. The industry quickly spread the claim that "paying £500 would get you British nationality in six weeks." This claim is not valid: the £500 buys a decision, not an oath, let alone a passport. The sentence in paragraph 42 locks the endpoint to the local council's calendar, and the £500 cannot move it.

My judgment is that the vast majority of people shouldn't spend this £500. Unless you have a hard deadline: an overseas posting order, a child's expected due date abroad, or a need to change your work status before a certain date. Without a hard deadline, the few months saved by expediting may be eaten back by the council's scheduling and subsequent passport processing, meaning you've spent the money but the total time hasn't really changed. It's more cost-effective to use this budget for other purposes, such as rechecking your English certificates and absence records.

So the honest version of the entire timeline is like this: A deduction of £1,839 on the submission day, collecting biometric information within a few weeks, standard channel waiting for a decision "within 6 months," after approval, the oath is arranged by the council and must be completed within 3 months, the certificate is obtained on the day of the oath, then the passport is processed with the certificate. Any acceleration in any part in between does not mean the end is advanced.

The passage to be recited at the ceremony is clearly written in Schedule 5:

"I will be faithful and bear true allegiance to His Majesty King Charles the Third, His Heirs and Successors, according to law."

After reciting this sentence, the matter is considered complete; before that, the letter in your hand was just a letter.
