The Home Office usually decides a naturalisation application within six months of receiving it. Some applications take longer. That is an aim, not a guarantee (Apply for citizenship if you have ILR or settled status).
This is general information as at 31 August 2026. It is not advice on your facts. Worldwide Immigration Ltd is an IAA-regulated immigration advice organisation (Ref F201900032). Advisers are not SRA-regulated solicitors.
For the full naturalisation picture — eligibility, absences, good character and tests — use the live guide: British Citizenship in 2026. This page is only about timing, fees and what the decision letter is.
Checked against GOV.UK on 31 August 2026. Fees and service standards change. Verify the live GOV.UK pages before you apply.
Guide AN, the Home Office naturalisation booklet (July 2026), says the Home Office aims to conclude applications within six months of the date the application is received (Form AN / Guide AN). The public page says you will usually get a decision within six months, that some applications can take longer, and that if yours will take longer you will be told before six months have passed (apply for citizenship). Form AN describes a six-month service level agreement.
That target covers the whole assessment: eligibility, residence, absences, good character, and knowledge of language and life.
Registration applications for children on form MN1 are described against the same six-month service level. There is no separately published faster target. Discretionary or complex nationality cases take longer.
Two clocks people mix up:
The standard six-month aim starts when the Home Office receives the application, not when you enrol biometrics. Enrolling biometrics is part of the process, not the start of the six-month standard.
The optional priority service uses a different clock. GOV.UK describes that service as usually 30 working days, counted from biometrics or the identity check, not from the six-month receipt date. Do not treat the two figures as interchangeable.
The Home Office does not publish an official breakdown of decision times below the six-month standard. Do not plan on an eight-to-fourteen-week figure as if it were official. Community trackers are not GOV.UK.
There is a citizenship priority service. It is not the same as the visa super-priority service.
As at 31 August 2026, live GOV.UK and Form AN say (faster decision; eligible citizenship types; Form AN):
Do not invent how often slots are available, who “usually” gets it, or a success rate. The Home Office can still take longer than 30 working days. The six-month standard remains the figure for applications that do not use priority.
Paying a regulated adviser to prepare the file is not the same thing as the Home Office priority fee. The only paid acceleration the Home Office itself describes for citizenship is this £500 priority service.
For a standard naturalisation application that is not using priority:
When you apply. You submit the online application and pay £1,709, plus the £130 ceremony fee — £1,839 in total. There is no statutory fee for nationality biometric enrolment. Optional UKVCAS enhanced or on-demand appointments can still cost extra.
Biometrics and documents. You book and attend a biometric enrolment appointment at a UKVCAS service point, and upload supporting documents.
Assessment. There is no case-progress tracker for nationality applications. In the ordinary course there is no contact at all during this period. Silence is normal. It is not evidence that the file has been lost.
On decision. A decision letter is issued. If the application is approved, the Home Office confirms that the application is successful and that you will be invited to a citizenship ceremony. Where a ceremony is required, you become a British citizen on completing it, not on the date of the approval letter.
Ceremony. You must arrange and attend a citizenship ceremony within 3 months of receiving the invitation (citizenship ceremonies). Guide AN also states 90 days. Both figures are official; public-facing GOV.UK uses 3 months. Miss the window without a good reason and the application can be refused, which means applying again. The cost of a standard ceremony is included in the fee you have already paid. A private ceremony may cost extra, set by the local authority.
At the ceremony. You take the oath of allegiance (or affirmation) and the pledge, and you are handed your certificate of British citizenship.
After the ceremony. You can apply for a British passport. You are a British citizen from the date of the ceremony, not the date of the approval letter.
That last distinction matters. Between approval and ceremony you are not yet British. Do not book travel or apply for a passport on the assumption that you are.
If you used priority, the assessment block is the one GOV.UK describes as usually 30 working days from biometrics or identity check. Ceremony timing after approval is unchanged.
The decision letter is the document everybody waits for and few people are told about in advance.
If the application is approved. You receive a letter confirming that the application has been successful and that you will be invited to a citizenship ceremony. In most cases the ceremony invitation comes from your local authority rather than the Home Office, and it may arrive separately and a little later. If several weeks pass after approval with no invitation, contact the local authority for the area where you live — the delay is usually there rather than with the Home Office.
Keep the letter. It is evidence that the application was approved; it is not evidence that you are already a British citizen. You will need the certificate issued at the ceremony for a passport application.
If the application is refused. The letter sets out the reason. There is no right of appeal against a refusal of naturalisation. You cannot take it to the First-tier Tribunal. The Home Office may reconsider its own decision on Form NR (fee £513; it expects an application within six months of the decision date, never 28 days) (Form NR; nationality policy v5.0, 15 June 2026). A fresh application is a separate option if the facts can be addressed. Judicial review is a High Court challenge to legality, not a rehearing. Worldwide Immigration Ltd does not conduct it. See the refusal section on British citizenship.
If the letter asks for more information. Occasionally the Home Office writes during the assessment asking for a specific document or explanation, usually with a short deadline. Answer it precisely, on time, and in the terms asked. A missed deadline on that correspondence can produce a refusal.
Some delay-causes are visible before you file. The Home Office has not published a league table of reasons.
Absences that need checking. If your travel history is close to the 450-day limit over five years, or the 90-day limit in the final twelve months, a caseworker has to reconstruct it and may write to you. (The spouse route uses 270 days over three years, still with 90 days in the last twelve months.) Guide AN counts whole days only: the day you leave and the day you return are not counted. A tabulated absence schedule attached to the application is easier to assess than a pile of passport stamps.
You must also have been physically in the UK on the day exactly five years before the Home Office received the application (three years on the spouse route). Being abroad on that single date is a statutory problem, not a processing delay.
Good character enquiries. A declared conviction, caution, fixed penalty, immigration breach or tax discrepancy can trigger a further check, often with another government department. Declare everything that the form and guidance ask for. An undeclared matter discovered later can be treated as deception, which is a different and more serious problem than the original matter.
Referee problems. You need two referees who meet the published criteria. If a referee is ineligible, unreachable, or their details do not check out, the Home Office writes to you and the case waits.
Missing or ambiguous documents. Incomplete residence evidence, a name that appears differently across documents, or an unexplained gap in the qualifying period all generate correspondence.
Complexity in the route itself. Discretionary applications, unusual registration provisions, statelessness, historic legislation, and nationality by descent take longer because they need a more senior decision.
What you can do
What you should not do
Current fees, verified against the Home Office immigration and nationality fees table in force from 8 April 2026 and the citizenship fees table last updated the same day. Check the live table before you pay.
Biometrics for nationality: no statutory fee.
The application fee is not refunded if you are refused. The £130 ceremony element is returned; the £1,709 (or the adult-registration application element) is not.
If you use priority, add £500.
There is no official end-to-end figure from “I have decided to apply” to “I hold a British passport”.
Working backwards, you still need time to sit any outstanding tests (the Life in the UK test must be booked at least three days in advance; popular centres book further out), time for the decision (usually within six months unless you use priority), up to three months for the ceremony after the invitation, and then a first British passport application. Treat that as planning colour, not a Home Office standard. It can be shorter or longer.
If you have not yet sat the Life in the UK test or an English test, see the tests section on British citizenship.
English for citizenship is speaking and listening at B1 (Guide AN; English language). The B2 change from 26 March 2027 is for settlement, not citizenship (Immigration Rules Appendix KoLL). Do not treat a settlement English change as a new citizenship test.
A longer (ten-year) route to settlement has been proposed. It is not law. It does not change the Home Office’s six-month citizenship decision standard on this page. Do not plan a naturalisation clock around a proposal.
An instruction on a citizenship file typically covers eligibility before you file, reconstructing absences, declaring good-character issues in the application rather than in later correspondence, and confirming that referees meet the criteria. If an application has already been filed and the six-month service standard has passed, the work is to review the papers and chase the Home Office through the published complaint route. That is not a private fast-track. The only paid acceleration the Home Office describes is the priority service above.

One CTA: British Citizenship in 2026.
The Home Office aims to decide naturalisation applications within six months of receiving them. GOV.UK says you will usually get a decision within six months and that some applications take longer. There is no official published figure below that six-month standard. An optional priority service, extra £500, is described as usually 30 working days from biometrics or identity check for eligible in-UK online applications.
Common reasons a caseworker needs more time include absences that have to be reconstructed, a good-character enquiry with another department, a referee who cannot be verified, missing residence evidence, or a discretionary route that needs a more senior decision. Six months is a service standard, not a guarantee. If the application will take longer, GOV.UK says you will be told before six months have passed.
There is a Home Office priority service for eligible citizenship applications, extra £500, usually 30 working days, in the UK, online only, from 20 July 2026. Super-priority is not available for citizenship. You cannot upgrade an application that has already been submitted. Paper forms cannot use it. Check the live GOV.UK eligible-types page. There is no separate private Home Office fast-track beyond that service.
If approved, the letter confirms that the application was successful and that you will be invited to a citizenship ceremony. It does not mean you are already a British citizen. Where a ceremony is required, you become a citizen on completing it, not on the date of the approval letter. The invitation usually comes separately from your local authority. If refused, it sets out the ground relied on. Some letters instead ask for a specific document within a short deadline, and those must be answered precisely and on time.
You must arrange and attend a ceremony within three months — 90 days — of receiving your invitation. If several weeks pass after approval with no invitation, contact the local authority for the area where you live. You become a British citizen on the ceremony date, not on the approval letter.
At the ceremony, not on the date of the approval letter. Between approval and ceremony you are not yet British, so do not book travel or apply for a passport on the assumption that you are. Your certificate is handed to you at the ceremony.
No. The six-month service standard runs from the date the Home Office receives your application. Enrolling biometrics is part of the process rather than the start of that clock. If you use the optional priority service, GOV.UK describes a different clock: usually 30 working days from biometrics or the identity check.
Naturalisation is £1,709 plus a £130 ceremony fee, £1,839 in total as at 31 August 2026. Registering a child on form MN1 is £1,000. Adult registration is £1,540 plus £130 ceremony, £1,670 total. If you are refused, the £130 ceremony element is returned but the application fee is not. Priority, if used, is an extra £500.
