Challenge 25 and Age Verification: The Complete Guide for UK Venues

Underage sales are the single most likely compliance failure to result in an immediate premises licence review. Trading standards and police conduct regular test purchase operations, and a single failure can trigger enforcement action.

Getting age verification right is not complicated. Getting it consistently right across every member of staff, every shift, every night - that is where most venues fall down.

The legal position

It is a criminal offence under Section 146 of the Licensing Act 2003 to sell or supply alcohol to a person under 18. The offence can be committed by:

• The person making the sale (the individual staff member)
• The premises licence holder
• The designated premises supervisor

Penalties include fines of up to £5,000, a criminal record for the individual, and a closure notice under Section 169A. A pattern of underage sales will almost certainly result in a premises licence review.

What is Challenge 25?

Challenge 25 is an age verification policy that requires staff to ask for proof of age from anyone who appears to be under 25. This gives a significant buffer above the legal purchase age of 18.

While Challenge 25 is not a statutory requirement, it is a mandatory condition on most premises licences. Even where it is not an explicit condition, failing to operate an effective age verification policy is treated as undermining the licensing objective of protecting children from harm.

Some venues operate Challenge 21. This is weaker and increasingly considered insufficient by licensing authorities. Challenge 25 is the standard.

Acceptable forms of ID

Your premises licence conditions may specify which forms of ID you must accept. The standard acceptable forms are:

Passport

The most reliable form of ID. Difficult to forge, contains a photograph, and includes a date of birth.

Driving licence

A full or provisional UK driving licence with a photograph. Check the date of birth and compare the photograph to the person presenting it.

PASS card

Any card bearing the PASS (Proof of Age Standards Scheme) hologram. These include:

• CitizenCard
• Young Scot card (in Scotland)
• Validate UK

Military ID

A Ministry of Defence identity card with a photograph and date of birth.

What is NOT acceptable

• Student cards - these verify enrolment, not age
• Bank cards - no date of birth or photograph
• Social media profiles - no verification whatsoever
• "I left my ID at home" - not an ID
• "My friend can vouch for me" - not an ID
• Photographs of ID on a phone - most licensing authorities do not accept these as they are easily doctored

If someone cannot produce acceptable ID and appears under 25, the answer is always no. There are no exceptions.

How to check an ID effectively

Step 1: Look at the person

Before they even produce an ID, look at the person. Does their apparent age require a challenge? If they clearly appear over 30, no check is needed.

If there is any doubt - and the threshold should be generous - ask for ID.

Step 2: Check the document

When examining an ID:

• Is it genuine? - check for signs of tampering, poor print quality, or misaligned text. Feel the card - genuine documents have specific textures and features
• Is it theirs? - compare the photograph to the person. Hair styles change, but bone structure does not
• Are they old enough? - calculate from the date of birth, do not just glance at the year. Someone born on 20 March 2008 is not 18 until 20 March 2026
• Is it in date? - expired documents may not be accepted under your licence conditions

Step 3: Make the decision

If the ID is valid and confirms the person is 18 or over, proceed with the sale. If there is any doubt about the ID's authenticity or ownership, refuse the sale.

Step 4: Record refusals

Every refusal should be recorded. More on this below.

The refusals register

A refusals register (or refusals log) is a record of every occasion when a member of staff refuses to sell alcohol because of age concerns. Most premises licences require you to maintain one.

What to record

• Date and time of the refusal
• Description of the person refused (approximate age, appearance)
• Reason for refusal (no ID, ID appeared fake, appeared intoxicated, suspected proxy sale)
• Staff member who made the refusal
• Outcome (did the person leave, become aggressive, attempt to purchase elsewhere in the venue?)

Why it matters

The refusals register demonstrates that your policy is active and being followed. A venue that cannot produce refusal records is telling licensing authorities one of two things: either staff never encounter underage purchase attempts (unlikely), or they are not applying the policy.

A healthy refusals register with regular entries is evidence of a working system.

Test purchases

Police and trading standards regularly send young-looking individuals (who are actually 18 or over, or in some cases under 18 with parental consent) to attempt to purchase alcohol at licensed premises. These are test purchases, and they are legal.

What happens if you fail

If a test purchase is successful (alcohol is sold to someone who should have been challenged):

• The individual staff member may receive a fixed penalty notice or be prosecuted
• The premises may receive a closure notice
• The incident will be reported to the licensing authority
• It may trigger a premises licence review

How to prepare

• Ensure every member of staff understands Challenge 25 and can explain it
• Run internal test exercises - have a young-looking staff member or friend attempt to buy a drink
• Review refusal records regularly to confirm staff are challenging
• Brief staff before every shift - a 30-second reminder keeps age verification front of mind

Proxy sales

A proxy sale occurs when an adult purchases alcohol on behalf of someone under 18. This is also an offence under the Licensing Act 2003.

Staff should be trained to recognise indicators of proxy purchases:

• A group where one person buys drinks while others wait nearby
• An adult purchasing an unusual combination of drinks (e.g., alcopops not consistent with their own apparent preferences)
• Communication between the purchaser and a group of younger individuals
• Direct observation of drinks being passed to someone who was refused service

If you suspect a proxy sale, refuse the transaction. You are not required to prove a proxy sale is occurring - reasonable suspicion is sufficient grounds for refusal.

Training your team

Key training points

• The Challenge 25 policy and why it exists
• Acceptable forms of ID and how to check them
• How to refuse a sale - confident, professional, non-confrontational
• How to complete the refusals register
• Proxy sale awareness
• What to do if a refusal leads to aggression (call for support, do not engage)

Training frequency

• Induction - every new starter before they serve their first drink
• Refresher - at least annually, more frequently if issues arise
• After incidents - if a test purchase fails or an underage sale is identified

Documentation

Record all training with dates, attendees, content, and signatures. This is your evidence that the policy is not just written on a wall but actively delivered to staff.

Practical checklist

1. Check your licence - what does it say about age verification? Challenge 25 or Challenge 21?
2. Acceptable ID list - is it displayed at the bar and known by all staff?
3. Refusals register - is it being completed consistently?
4. Staff training - can every member of bar staff explain the policy?
5. Signage - is Challenge 25 signage visible to customers?
6. Test yourself - when did you last run an internal test exercise?
