Selling alcohol to someone under 18 is the offence most likely to end a hospitality career — and it’s committed by decent, busy staff who “thought they looked old enough”. The defence the law gives you is process: Challenge 25, valid ID, and a recorded refusal. Here’s how to run it properly.
What the law actually requires
Since 2010 every licensed premises in England and Wales must operate an age verification policy — it’s a mandatory licence condition. The policy must require ID from anyone appearing under 18; almost all operators set the threshold at 25 (Challenge 25) to build in a safety margin. In Scotland, Challenge 25 is written into law directly.
Acceptable ID — and nothing else
- A passport (any country, in date)
- A photocard driving licence (full or provisional)
- A PASS-hologram card (e.g. CitizenCard)
- UK Defence Identity Card / certain biometric immigration documents
Student cards, bank cards, photos of a passport on a phone, birth certificates — no. If the customer can’t produce genuine physical ID from the approved list, the sale is refused, every time, regardless of how old they claim to be.
What it costs to get wrong
- The staff member: a £90 fixed penalty notice or prosecution with an unlimited fine — personally.
- The business: prosecution, and for persistent selling (twice in three months) a fine up to £20,000 and suspension of alcohol sales.
- The licence: a review, with conditions, suspension or revocation on the table — plus the DPS’s personal licence at risk.
Councils and police run test purchasing continually. The only reliable defence is showing you took “all reasonable precautions and exercised all due diligence” — which in practice means documented training and a working refusals log.
Training your team properly
A toolbox talk isn’t enough to evidence due diligence. Put every member of staff who sells or serves through a certificated course:
- The AUASP — Award for Underage Sales Prevention is the recognised qualification, covering ID checking, refusal technique, proxy sales and record keeping.
- Our short Age Verification course is ideal for rapid onboarding of seasonal and part-time staff.
- In Scotland, the mandatory 2-hour staff training is covered by the SALPS award.
Keep the certificates on file, refresh annually, and record one-to-one sign-offs for new starters before their first solo shift.
Refusing without a scene
Teach the script: apologise, blame the policy, keep it impersonal — “Sorry, without ID from the approved list I can’t serve you; it’s the licence conditions, not my call.” Log every refusal (time, description, reason). A full refusals book is gold at a licence review; an empty one suggests either nobody’s checking or nobody’s recording.
Frequently asked questions
Is Challenge 25 a legal requirement?
An age verification policy is legally required everywhere in Great Britain; 25 as the challenge age is mandatory in Scotland and near-universal best practice in England and Wales.
What about proxy purchases?
Buying alcohol for someone under 18 is a separate offence. Train staff to watch handover behaviour outside off-licences and refuse sales they suspect are proxies.
Do delivery drivers need age verification training?
Yes — age must be verified at the point of delivery for online alcohol sales, and your due-diligence defence needs to cover that leg too.
