How long does it take to become a British citizen? £1,709 fee and the schedule for submission to swearing-in
The naturalization application fee increased to £1,709 on April 8 this year.
Plus the £130 oath fee that must be paid at submission, £1,839 is deducted from the card at the moment of submission. Compared to the previous tier of £1,605, it has increased by £104. This number itself is not enough to keep one awake at night. The tough part is the period after the money is paid, when there is 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 based on that service standard mentioned on the UKVI website, but rather on section 42 of the British Nationality Act 1981. If you break down that section sentence by sentence, the shape of the entire timeline will become apparent.
The cost of British citizenship: £1,839 is deducted in full on the day of submission
First, balance the accounts. The following table shows all official fees from the exam to the oath, excluding the agency fee.
| Link | Fee | Time |
|---|---|---|
| Life in the UK Test | £50 | Schedule by test center, requires prior booking |
| submit Form AN | £1,709 + £130 | Pay in full on the same day |
| Biometric Information Collection | Standard Appointment Does Not Charge Additional | Submit and Follow the Center's 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 that needs to be brought on the day of the oath, but rather it is bundled with the application fee and deducted together on the submission day. If the application is rejected, or withdrawn before the oath, this £130 will be refunded; £1,709 is non-refundable. The actual amount put at risk is only £1,709, the remaining part is a refundable portion - make sure you understand this before deciding whether your documents are complete enough to submit.
The threshold conditions remain the same: ILR, have been here for 12 months, absence in the last 12 months no more than 90 days, total absence over five years no more than 450 days, Life in the UK plus B1. These points are well known, no need to repeat. The reminder is that absence days are counted based on passport stamps and boarding records, not based on 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, you can use it by clicking the bottom menu bar.

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 take the oath; legally, it does not give you any status. The real-world equivalent 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 for 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 at the ceremony. The date is arranged by your local council, not by UKVI. The speed of scheduling completely depends on the number of sessions the council has that season, and the result can be different for the same person if they move to a different area.
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 canceled; indeed, the Home Secretary can extend or exempt under s.42(5), (6) in exceptional circumstances, but that is a discretionary power, not a right, and the stance here holds even if it's just one day late. Therefore, once you receive the approval letter, the first thing to do is to contact the council on the same day to book a spot, especially for those with long-distance travel plans in the next three months.
There is another consequence that almost no one mentions: the date when the naturalization takes effect on the certificate is the day of the oath of allegiance, , not the date of the approval letter. It has little impact on families within the UK, as parents who are already settled in the UK are already considered settled; however, if a child is born outside the UK, and the birth occurs after the approval but before the oath, the parents were not legally British citizens at that time, so the child cannot obtain British citizenship by descent. The period between approval and the oath usually spans several weeks to months, and for families who often return to their home country during late pregnancy, this time difference needs to be carefully scheduled as a real-life schedule.
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 immediately spread the claim that "paying £500 would get you British nationality in six weeks." This claim is not valid: the £500 buys a decision on , not an oath of allegiance, 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 assignment order, your child's 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 duration has hardly changed. It's more cost-effective to use this budget for other purposes, such as double-checking 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 must be arranged by the council and 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 segment does not mean the end is advanced.
The passage to be read 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 finally over; before that, the letter in your hand was just a letter.
