This guidance is for England and Wales
The sale of alcohol in pubs, restaurants, etc is subject to the requirements of weights and measures, fair trading, licensing and underage sales legislation.
There are legal requirements for the licensed trade concerning the quantities and measurement of alcoholic drinks and how they are described, as well as on informing customers about the prices they will be charged. There are also mandatory licensing conditions, which include minimum quantities and irresponsible price promotions. All customers must be over 18 to buy alcohol in licensed premises.
Weights and measures requirements
There are legal requirements for the quantities that specific types of alcoholic drinks must be sold in. These apply to beer, lager, cider, gin, rum, vodka, whisky, wine and fortified wines (such as port and sherry).
There are no specific requirements as to the quantities that any other drinks have to be served in. However, if a specific quantity is indicated to customers on, for example, a menu or price list, the requirements detailed below (regarding equipment or measures to be used to determine the quantity served) should be followed.
Beer, lager and cider
Draught sales of beer, lager and cider must be made in one of these quantities:
- 1⁄3 pint
- 1⁄2 pint
- 2⁄3 pint
- multiples of 1⁄2 pint
These requirements do not apply when beer, lager or cider is mixed with other drinks. However, if you agree to sell a customer a particular quantity of a mixed drink - a pint of shandy, for example - the requirements given below regarding measuring the drink should be still be followed.
Draught beer, lager or cider should be measured using either an automatic metering system or glasses of a relevant quantity. All such equipment and glasses should be 'Government stamped'; this is explained further below and guarantees that the quantity served will be accurate.
Stamped glasses used to measure and serve draught beer, lager and cider can be either brim measures (where they need to be filled to the top of the glass) or lined glasses (where there is space above the quantity line to accommodate drinks with a frothy head). In either case drinks should be dispensed with care to ensure they are filled to the required level, having regard to the nature of the drink - for example, stout is traditionally served with a large frothy head whilst ciders are not. If customers consider that the amount of frothy head served is excessive they can ask for the glass to be topped up to a reasonably acceptable level.
If automatic half-pint meters are used, glasses that the drinks are dispensed into should be slightly bigger than the amount being served to allow for any frothy head produced to be accommodated. These glasses should not be stamped or have a particular quantity marked on them as this could cause customer doubt over the amount they are being served. The allowable accuracy of stamped meters and glasses is different and a metered pint of beer, for example, may not always come up to the line on a stamped pint glass.
Sales by the jug or pitcher
Beer, lager and cider can be sold in jugs or pitchers as long as:
- the quantity is made known to the customer
- the quantity is a multiple of a half-pint
- stamped equipment, measures or glasses are used to determine the amount served
For example, a four-pint pitcher of beer can be filled by dispensing eight half pints from a metered system or by filling four stamped, lined pint glasses; lined glasses being essential to allow for any frothy head produced.
Gin, rum, vodka and whisky
These four spirit drinks are required to be served by the glass in one of these quantities:
- 25 ml
- 35 ml
- multiples of 25 ml or 35 ml
The same quantity must be sold in all bars of the same premises and a notice must be displayed clearly informing customers which quantity is being used - for example:
These requirements do not apply when gin, rum, vodka or whisky is served as a cocktail in a mixture with two or more other drinks.
The quantity served must be determined using 'Government stamped' automatic measuring devices such as spirit measuring instruments (SMIs) or by using 'thimble' measures, which guarantees that the quantity served will be accurate.
When using SMIs of the 'optic'* type on bottles you should ensure that the measuring chamber is not obscured by price stickers etc so that the chamber can be seen to be full before use. The measuring chamber should be allowed to fully refill before another measure is dispensed.
[*Optic is a brand name, but is often used as a generic description for similar SMIs.]
Bottle-top pouring devices attached to spirit bottles should not be used to determine the quantity of measures of gin, rum, vodka and whisky even if they are marked with a relevant quantity indication. These devices are not legally accurate and are intended for use in making cocktails. If you use bottle-top pourers as a convenience, a stamped 'thimble' should also be used when serving gin, rum, vodka and whisky neat or with a single mixer drink.
When using 'thimble' measures that are required to be filled to the brim, it is good practice to hold the 'thimble' over the glass in which the drink is to be served whilst it is being filled; this will ensure that the customer gets the benefit of any spillage and is not served short measure.
Wine by the glass must be sold in the following quantities:
- 125 ml
- 175 ml
- multiples of 125 ml or 175 ml
The quantity of wine by the glass served must be clearly indicated to customers on menus, price lists or on a displayed notice - for example:
Wine sold in quantities of less than 75 ml or mixed with other drinks is exempt from these requirements.
Wine served in open carafes should be in one of these quantities:
- 250 ml
- 500 ml
- 750 ml
- 1 l
Fortified wine (port or sherry, for example) must be sold in either 50 ml or 70 ml quantities, or multiples thereof, and the customer must be informed which quantities are being used.
The quantity of wine by the glass can be determined using SMIs, 'thimble' measures or lined glasses. All equipment, measures, carafes or glasses used to determine the quantity of wine served must be 'Government stamped', which guarantees that the quantity served will be accurate.
Stamped measuring equipment and glasses
As detailed above, all measuring equipment, measures, glasses, etc used for determining quantities of alcohol sold should be 'Government stamped'. The stamp applied ensures that the equipment, measure or glass is accurate and has been made to specific legal requirements.
The crown stamp will be found on SMIs and automatic beer metering equipment. It may also be seen on older 'thimbles' and glasses still in use:
Newer 'thimbles' and glasses are CE-marked:
And since 1 January 2021 they have been UKCA-marked:
There is no requirement to dispose of older equipment, so CE-marked 'thimbles' and glasses may still be used.
All equipment, beer meters, SMIs, 'thimbles' and glasses used to measure alcoholic drinks should be checked to ensure they have a stamp on them, which on newer equipment may only be visible on the inside of the bottom of the glass or measure, or on the base of a glass stem.
The crown symbol may be used on new glasses but only in addition to the legal marks. The Government has produced guidance on this.
Bottled drinks and drinks not required to be sold in specific quantities should be served in plain, unstamped glasses to avoid customer confusion and possible complaints of short measure being served.Back to top
Information to be provided to customers
The Consumer Protection from Unfair Trading Regulations 2008 require consumers to be fully informed about goods and services - which includes descriptions of alcoholic drinks and indications of prices charged in licensed premises - before they decide to make a purchase. More information on this general legislation can be found in 'Consumer protection from unfair trading'.
The best way to ensure that customers are given the required information is by the use of detailed menus or clearly displayed price lists that indicate the following:
- accurate product descriptions, including alcoholic strengths where appropriate
- the price, inclusive of VAT
- the quantity of drink served, where appropriate
- any compulsory additional service charge
- any compulsory minimum charge per customer
If customers are not informed about prices prior to placing an order, they may have the right to refuse to accept and pay for drinks - for example, if the price charged is excessively more than the customer would reasonably expect to have to pay.
Names used to describe drinks on price lists, menus, etc should be accurate. For example, particular brand names such as 'Bacardi' and 'Coke' should not be used when other brands of white rum and cola are actually served.
Advertising signs attached to beer pumps and SMI stands must accurately indicate the brand of drink being dispensed and need to be checked regularly, particularly where guest beers, drink brands, etc have been changed.
Do not use particular brand names in menus or on price lists etc if you do not always stock specific brands of drinks. If all brands of a particular type and quality of drink are sold at the same price, use generic descriptions such as 'white rum', 'whisky', 'vodka', etc.
If you do not provide the customer with all or part of the information necessary, or give misleading information, this may be regarded as an unfair trading practice and constitute an offence.Back to top
Licensing Act requirements
Mandatory conditions placed on licensed premises selling alcohol include the following.
Customers who do not request a particular quantity of a drink to be served must be informed of the smallest measure available for that drink - for example, 1⁄2 pints of beer or 125 ml glasses of wine.
This is to encourage responsible drinking by preventing a default larger measure being served. Customers must be informed of the availability of these quantities of drinks by means of displays in menus, price lists, etc as well as verbally when, for example, a 'glass of wine', 'a beer' or 'a whisky' is asked for.
Irresponsible price promotions should not be used - for example:
- buy one get one free
- all you can drink for £10
Free drinking water must be available for customers on request.
Any continued breach of these conditions could result in suspension of a licence to sell alcohol or even removal of the licence.Back to top
Alcohol can only be bought, bought for, or consumed on licensed premises by customers who are 18 or over. It is an offence to supply alcohol to a customer who is under 18, and continued breaches of this by licensed-premises operators can result in suspension or revocation of a licence to sell alcohol. However, 16 and 17-year-olds can drink beer, lager, wine or cider, bought for them by someone accompanying them who is 18 or over, when they are eating a meal in a restaurant, hotel or parts of a pub specifically set aside for eating meals.
It is very important to ensure that sales of alcohol are only made to customers who are 18 or over. As the age of young people is often very difficult to assess, it is recommended that an age-verification policy is adopted to ensure that young customers can prove their age. Quite often the use of an age-verification policy is a condition applied when a licence to sell alcohol is granted.

Beer walls and at-table self-service systems have become popular in recent years, but require specialist installation and maintenance. If you are considering installing these systems in your premises, please contact your local trading standards service for advice.Back to top
For more information on the work of trading standards services - and the possible consequences of not abiding by the law - please see 'Trading standards: powers, enforcement and penalties'.
In addition to the information covered in the above guide, there are various measures that can be taken for breaches of Licensing Act requirements that can affect the licensee, such as the imposition of extra licensing conditions and temporary suspension or revocation of alcohol sales licences.Back to top
