The nationality priority service allows applicants to pay an additional £500 on top of the standard citizenship application fee to have their application processed more quickly.
If you use the service, you should normally receive a decision within 30 working days of attending your biometric appointment, where your fingerprints and photograph are taken.
However, there are two important points to bear in mind:
The priority service speeds up the decision-making process only. It does not affect the way your application is assessed.
As of July 2026, the standard Home Office fee for an adult applying to become a British Citizen (known as naturalisation application) is:
This means the total standard cost is £1,839.
Applicants who choose the nationality priority service will pay an additional £500, bringing the total Home Office fees to £2,339.
Different fees may apply to children's registration applications and other routes to British citizenship.
-Fees are correct as of 8 July 2026
A standard British citizenship application can take up to six months to be decided.
Applicants using the new priority service should normally receive a decision within 30 working days of attending their biometric appointment.
While most applications should be processed within this timeframe, some cases may take longer if:
As a quick guide, to apply for naturalisation as an adult you will usually need to show that you:
Every application is assessed individually, and additional requirements may apply depending on your circumstances, so obtaining legal advice before applying can help avoid costly mistakes and delays.
Most applicants will need the following documents:
Preparing your documents properly before applying can help reduce delays and minimise the risk of problems during the application process.
Separately from the paid service, the Home Office can agree to prioritise a citizenship application free of charge, but only in limited situations. You will need to ask, explain your reasons and provide evidence, and each request is considered on its own facts.
The Home Office will first look at whether your case has been mishandled or overlooked, or whether it has been outstanding for more than 12 months without good reason. Beyond that, the sorts of circumstances that may justify free priority treatment include where you:
However, free priority treatment differs significantly from the paid service.
The free priority treatment is not a fast-track guarantee. The degree of priority depends on the nature of the case and how far it has already progressed. The Home Office does not guarantee a decision date and may simply begin work on the application sooner but may not be able to meet a particular deadline even where priority is agreed. The paid priority service remains the only option that comes with an expected decision within 30 working days.
The same applies to children’s applications (known as registration). One point to note: where a child’s application is linked to a parent’s naturalisation application, free priority is generally only available if the child’s application can be decided in its own right. If the outcome depends on the parent’s application being decided first, priority will only be given in exceptional circumstances.
If your circumstances do not fit within these categories, the paid priority service described above is the way to obtain a faster decision.
Yes.
You can continue travelling while your citizenship application is being considered because your existing immigration status remains valid until you become a British citizen.
For example, if you hold:
you can generally continue travelling as normal while your application is pending.
The more important travel consideration arises after your application has been approved.
Once you attend your citizenship ceremony and become a British citizen, your previous immigration status comes to an end.
Since 25 February 2026, new British citizens can no longer re-enter the UK using only their foreign passport. New British citizens generally need a British passport (or a certificate of entitlement in their foreign passport) before they can return to the UK following international travel. A first British passport can take several weeks to arrive.
This means that between your ceremony and receiving your British passport, international travel can be difficult. A standard citizenship application can leave you in a long period of uncertainty, which makes it hard to plan trips abroad. The new priority service shortens the whole process considerably, so you can plan your ceremony, your passport application and your travel with much more confidence.
If you have important travel commitments coming up, for work, family or otherwise, the priority service may be a worthwhile investment.
Whether the priority service is worthwhile depends on your circumstances.
The service may be particularly helpful if you:
The service does not increase your chances of success, but it can significantly reduce the waiting time for a decision.
No. The priority service only affects how quickly your application is decided, not the outcome. Your application is assessed against exactly the same requirements as a standard application, and paying for priority does not make approval any more likely.
No. The priority fee is non-refundable, even if your application is refused or takes longer than 30 working days to decide. It is therefore important to be confident that your application is well prepared before you submit it.
No. You must select the priority service at the time you apply. An application that has already been submitted cannot be upgraded.
The 30-working day period starts from the date you attend your biometric appointment, not the date you submit the online application.
No, not in every case. Applications that are particularly complex or need additional checks may take longer, and the priority fee is not refunded if this happens.
Yes. The priority service is available for children's citizenship registration applications. However, where a child’s application depends on the outcome of a parent’s application, the parent’s application will still need to be decided first.
Yes. Adults must attend a citizenship ceremony after approval, and you only become a British citizen once you have done so. The priority service speeds up the decision, not the ceremony or passport stages.
Yes. Your existing status, such as indefinite leave to remain or settled status, remains valid while your application is being considered. The difficult period is after your citizenship ceremony, when you will need a British passport to re-enter the UK – which is one reason a faster decision can help you plan travel.
Only in limited circumstances, such as compelling compassionate reasons, urgent travel needs or Home Office error – and even then it is discretionary, requires evidence and does not come with a guaranteed timescale. The paid service is the only option with an expected 30-working-day decision.
Most applicants will require passport evidence, immigration status documents, proof of English language ability, a Life in the UK Test certificate and details of absences from the UK.
The service can be beneficial for applicants who need a quicker decision, have travel plans, work commitments or simply want certainty sooner. We can advise you on whether it is worthwhile in your case – contact us on 0115 964 4123 or enquiries@paragonlaw.co.uk.
