Minimum unit pricing

The Sheffield Addictions Research Group has been highly influential in the introduction of minimum unit pricing (MUP) for alcohol in Scotland, Wales and the Republic of Ireland. Here we answer some common questions about minimum unit pricing.

What is minimum unit pricing?

A minimum unit price (MUP) sets a floor price below which a unit of alcohol cannot be sold to consumers. This means that the floor price is directly linked to the amount of alcohol contained in the product. For example, a 50p MUP would mean that a pint of beer containing two units of alcohol would need to cost at least £1.00 and a bottle of wine containing nine units would need to cost at least £4.50. The table below shows the effect of a 50p MUP on a range of alcohol types.

MUP only directly affects products sold below the floor price. This means the price of a pint in the pub would not be affected, nor would most other drinks sold in pubs, restaurants or nightclubs. All of these are already priced at well above 50p per unit. Instead, the main impact of MUP would be on alcohol sold in supermarkets and off-licences, particularly multipacks of beer and cider, cheaper spirits brands and strong 'white' ciders.

Where does the additional revenue from the minimum unit price go?

Introducing an MUP leads to an increase in the sales price of some alcoholic products (i.e. those that were being sold below the MUP threshold). Although people will respond to these increases by buying less alcohol overall, our total spending on alcohol is likely to increase.

An important difference between an MUP and an increase in alcohol taxes is where this additional revenue goes. When taxes increase, the additional revenue goes directly to government. Under an MUP, although a proportion of the increase in sales price for affected products does go to the government in the form of VAT, the majority of the additional revenue from selling alcohol at higher prices goes to the retailers and producers of alcohol. As a result, we would expect the profits of shops, supermarkets and companies who make alcoholic products to increase under an MUP.

Some commentators have proposed the introduction of a 'windfall tax' on the profits of alcohol retailers and producers to recover some of this additional revenue for government. However, to date, no country with an MUP has introduced such a measure.

Which countries have introduced minimum unit pricing?

Scotland passed legislation to introduce MUP in 2012 and implemented a 50p MUP in May 2018 after a five-year legal challenge led by the Scotch Whisky Association. In August 2024 the Scottish government increased the MUP level to 65p per unit.

Wales introduced a 50p MUP in March 2020 and the Republic of Ireland implemented an MUP set at €1 per Irish standard drink (equivalent to around 70p per UK unit) in January 2022. The Northern Irish government have also announced their intention to introduce an MUP.

Beyond the UK and Ireland, Armenia and Australia's Northern Territory also have MUPs that apply to all alcohol, while Russia, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Slovakia, Ukraine, Uzbekistan, several Canadian provinces and Australia's Northern Territory all have forms of minimum pricing in place that cover at least some alcoholic products (e.g. a minimum sales price for a 700ml bottle of vodka).

What is the evidence for minimum unit pricing?

There is a strong, and growing, body of research evidence showing that MUP policies are effective at reducing alcohol consumption and associated harms. This evidence falls broadly into three categories:

There is an extensive and robust body of international evidence showing that increases in the price of alcohol are associated with falls in both alcohol consumption and alcohol-related harm. This evidence includes several systematic reviews and meta-analyses that bring together evidence from over 100 studies.

A further comprehensive body of evidence has demonstrated the association between alcohol consumption and a wide range of health conditions, with higher levels of drinking associated with greater risks of harm.

MUP is a specific form of price increase which targets the price of cheap, high-strength alcohol that is disproportionately purchased by those drinking larger amounts of alcohol. As a result, there is strong evidence to support that introducing an MUP will reduce alcohol consumption, particularly among heavier drinkers, and that alcohol-related harms will fall as a result.

Public health policy modelling, in which computer models are developed that can draw together many different datasets and sources of evidence to estimate the potential future trends in population health under different scenarios, is an increasingly influential approach used to understand the possible impact of alternative policy options.

Since 2008, the Sheffield Addictions Research Group (SARG) has been developing and using the Sheffield Alcohol Policy Model (SAPM) to estimate the impact of MUP in different countries and at different times. Analysis from SAPM has informed the policy processes in Scotland, Wales and the Republic of Ireland that led to MUP being implemented as well as playing an important role in policy debates around MUP in Northern Ireland, England and internationally, with versions of the model having been developed for South Africa and parts of Canada and Australia.

The model consistently finds that the policy is an effective and well-targeted approach to reducing alcohol-related harm. As well as cutting the number of deaths, hospital admissions and crimes caused by alcohol, this work also finds that MUP avoids increasing the price of alcohol purchased by moderate drinkers, including those moderate drinkers who are on low incomes.

Analyses from SAPM have previously been published in The BMJ, The Lancet and PLoS Medicine.

Since 2014, SARG has been working on a new policy model that can jointly examine the impact of alcohol and tobacco policies, as well as taking a lifecourse-based approach to individual drinking and health. This model, the Sheffield Tobacco and Alcohol Policy Model (STAPM), has been used to model the impact of changing Scotland's MUP level from 50p per unit, finding that an increase in the MUP threshold would further reduce alcohol consumption and harms.

Several other teams of researchers have also modelled the impact of MUP, including the OECD and researchers in Australia and Canada. These studies have consistently reached similar conclusions, that MUP is an effective and well-targeted public health policy.

In recent years, with the introduction of MUP in several countries and jurisdictions, there is a growing body of evidence on the real-world impacts of MUP.

The largest set of studies comes from Scotland, where a large formal evaluation programme has evaluated many aspects of the impacts of the policy. This evaluation found that alcohol sales fell by 3% following the introduction of MUP in 2018, with the biggest falls in purchasing among households that bought the most alcohol.

Deaths directly caused by alcohol consumption fell by 13.4% (156 fewer deaths per year) and hospital admissions by 4.1%. The biggest reductions in deaths were identified among the most deprived groups, meaning that MUP has contributed to reducing health inequalities.

The evaluation also found no consistent evidence of any negative impact on the alcohol industry.

However, studies within the evaluation found no consistent evidence of either positive or negative impacts on wider social outcomes including ambulance callouts, crimes or road traffic accidents.

The evaluation also found no significant evidence that very heavy drinkers turned to theft or illicit alcohol or switched to illicit drug use, although there was some evidence that a minority of harmful drinkers experienced additional financial strain.

There are also a range of studies from Australia, evaluating the impacts of introducing an MUP, alongside a range of other measures to address alcohol harms, in the Northern Territory in 2018. These studies have found consistent evidence of positive impacts on health and social outcomes including ambulance callouts, assaults, road traffic crashes and child protection cases, although these cannot be solely attributed to MUP due to the other policies implemented at the same time.

Other direct evidence continues to emerge on the impacts of MUP in Wales, as well as a number of studies from Canada and Eastern Europe that look at the impact of increasing the level of Minimum Prices, which are similar, but not identical, to MUP. These studies have also shown consistent evidence of positive impacts on alcohol-related harms.

Across all three forms of evidence, and many individual studies, a clear picture has emerged showing that MUP is effective at reducing alcohol consumption and alcohol-related harms.

How does minimum unit pricing affect particular groups?

A key part of the appeal of MUP to policy makers is the fact that it effectively targets the cheap alcohol, that is drunk disproportionately by heavier drinkers, while having relatively little impact on the alcohol consumed by moderate drinkers. This remains true even among lower income groups, who pay less, on average, per unit of alcohol, than those in higher income groups.

Figure 1 shows how the proportion of alcohol bought in different price bands differs between drinker groups and income quintiles. This illustrates that while drinkers on lower incomes buy more cheap alcohol across all levels of drinking, heavier drinkers buy a substantially greater proportion of their alcohol at the lowest prices within each income quintile.

The targeted impact of MUP becomes even clearer when we convert these proportions into total units purchased each week, shown in Figure 2. Here we can see that the overwhelming majority of alcohol being bought at the lowest prices is being purchased by heavier drinkers, particularly heavier drinkers on lower incomes.

Having a greater impact on the price of alcohol purchased by heavier drinkers on lower incomes is important for the inequality impacts of MUP. Alcohol harm rates are substantially higher in more deprived groups, with around four times as many deaths from alcohol-specific causes in the most deprived, compared to the least deprived, 20% of the population. As a result, reducing alcohol consumption among heavier drinkers in more deprived groups is key if we want to reduce alcohol-related inequalities in health.

Findings from the evaluation of the introduction of MUP in Scotland have demonstrated this effect in practice, with the largest reductions in deaths from alcohol-specific causes being seen in the most deprived groups. This is illustrated in Figure 3.

Why introduce minimum unit pricing rather than alcohol duty increases?

MUP

  • Only increases the price of the cheapest alcohol
  • More effectively targeted at heavier drinkers
  • Bigger reduction in health inequalities
  • Price increases must happen

Tax

  • Increases the price of all alcohol
  • Additional revenue goes to the government through tax increases
  • Still reduces alcohol-related harm and health inequalities, but to a smaller degree

Increasing alcohol taxes is another effective way of reducing alcohol consumption and related harm. However, MUP specifically targets the cheaper and higher-strength alcohol that is favoured by heavier drinkers. As a result, it leads to larger reductions in consumption among high risk drinkers and larger reductions in deaths and hospital admissions caused by alcohol.

Our previous analysis has found that, to achieve the same impact as a 50p MUP, alcohol taxes would need to increase by between 27% and 70% depending on which outcome you wish to match.

Other considerations when comparing the two policy options include that the additional revenue from higher prices goes to retailers under MUP but to Government under increased taxes. MUP also legally enforces price increases for products being sold below the MUP threshold, whereas the cost of tax increases can be either absorbed by the industry, distributed unevenly across alcoholic products or passed on to non-alcoholic products.

In line with these possibilities, our analyses suggest that when alcohol taxes go up, cheaper drinks increase in price by slightly less than would be expected and the price of more expensive drinkers increases by slightly more than would be expected. Essentially this means that people buying more expensive alcohol are subsidising lower price increases for the cheapest products.

It's also important to recognise that MUP does not have to be treated as an alternative to increasing alcohol taxes as both policies can be enacted together.
