What Are Biometrics?

In the context of UK immigration, biometrics refers to your fingerprints and a digital facial photograph. The Home Office collects these to verify your identity and link your physical identity to your immigration record. Biometrics are required for most visa applications, extensions, settlement applications, and citizenship applications.

Your biometric data is stored securely and is used throughout your immigration journey. When you enter the UK, border officers can match your fingerprints against the database to confirm your identity.

When Do You Need to Give Biometrics?

You need to provide biometrics for almost every UK immigration application, including:

Some application types are exempt, such as certain visitor visa applications for nationals of countries that do not require biometric enrolment. However, the vast majority of applicants will need to complete this step.

Applying from Outside the UK: Visa Application Centres

If you are applying from overseas, you attend a Visa Application Centre (VAC) operated by the Home Office's commercial partners (currently TLScontact or VFS Global, depending on your country).

How to Book

  1. Complete your online visa application on GOV.UK and pay the fee.
  2. After submitting, you will be directed to the VAC booking system.
  3. Choose your nearest centre and select an available date and time.
  4. You will receive a confirmation email with instructions on what to bring.

What Happens at the Appointment

  1. Arrive at the centre with your passport, confirmation email, and supporting documents.
  2. A staff member will check your identity and verify your appointment.
  3. Your fingerprints are scanned electronically (all 10 fingers).
  4. A digital photograph is taken.
  5. Your supporting documents may be scanned or collected.
  6. You receive a receipt confirming your submission.

The entire appointment usually takes 15 to 30 minutes, though waiting times vary. Some centres offer premium services (priority appointments, comfortable lounges) for an additional fee.

Applying from Inside the UK: UKVCAS Centres

If you are extending your visa or applying for ILR from within the UK, you attend a UK Visa and Citizenship Application Services (UKVCAS) centre, operated by Sopra Steria.

How to Book

  1. Complete your online application on GOV.UK and pay the fee.
  2. You will be redirected to the Sopra Steria website to book your appointment.
  3. Choose a UKVCAS centre and select a date. Free appointments are available but may have longer wait times. Paid appointments offer earlier dates.
  4. Bring your documents to the appointment.

UKVCAS centres are located in major cities across the UK, including London, Manchester, Birmingham, Glasgow, Cardiff, and Belfast. You can choose any centre regardless of where you live.

The IDV App: Biometrics from Your Smartphone

For some in-country applications, you can complete the biometric step using the UK Immigration: ID Check smartphone app, instead of attending a centre in person.

The app is available for applicants who:

  • Are applying from inside the UK
  • Hold a biometric passport (with an electronic chip)
  • Are applying on a route that supports the app (not all routes do)

Using the app, you scan your passport's chip using NFC (near-field communication), take a selfie photograph, and the app verifies your identity. This replaces the need to attend a UKVCAS centre.

The app is free and available for both iOS and Android. It is generally faster and more convenient than attending a centre, though it can be frustrating if your phone has trouble reading the passport chip.

What to Bring to Your Appointment

Whether you attend a VAC or UKVCAS centre, you should bring:

  • Your valid passport. This must be the passport you used in your application.
  • Appointment confirmation. Print it or have it available on your phone.
  • Supporting documents. These vary by application type. Check your application confirmation for a list of what is required.
  • Previous BRP (if you have one), even though it has expired.

Do not bring unnecessary items. Centres may have restrictions on bags, electronic devices, and food or drink.

Tips for a Smooth Appointment

  • Arrive early. At least 15 minutes before your scheduled time.
  • Ensure your hands are clean and dry. Dirty or wet fingers can cause problems with fingerprint scanning.
  • Remove any hand jewellery. Rings can interfere with the fingerprint scanner.
  • Do not wear heavy makeup or glasses for the photograph (unless you wear glasses constantly for medical reasons).
  • Keep documents organised. Have everything in order to speed up the process.

What If You Cannot Give Fingerprints?

If you have a medical condition that affects your fingers (for example, severe eczema, missing fingers, or bandaged hands), inform the centre staff. They will note the issue and may attempt to scan whichever fingers are available.

If none of your fingerprints can be captured, this is recorded on your file. It does not prevent your application from being processed, but you may need to provide additional evidence of identity.

After Your Biometrics Appointment

Once your biometrics are recorded, the Home Office begins processing your application. Processing times depend on the type of application:

  • Overseas applications: The clock starts from the date you attend the VAC.
  • In-country applications: Processing typically begins after your UKVCAS appointment or IDV app submission.

You can track your application status through the GOV.UK tracking service.

Once a decision is made, your eVisa will be updated with your new immigration status.

Next Steps

After submitting your online application, book your biometrics appointment as soon as possible. Earlier appointments mean earlier processing. If you are eligible for the IDV app, consider using it for convenience.
