The pound has fallen more than 18% since the June 23 Brexit vote, putting inflationary pressure on manufacturers and lifting U.K. consumer prices the most in more than two and a half years.
Heineken said that it would be adding 6 pence to the cost of a pint and Carlsberg said it would be raising prices by 2.6% on average. The brewers this week said they are struggling with an increase in the cost of raw materials, changes in U.K. business rates and an increase in the national living wage.
The head of the British Beer and Pubs Association warned that the beer inflation could rise significantly this year.
BBPA chief executive Brigid Simmonds told The Guardian newspaper that although beer is predominately made domestically, the depreciation in the currency "means there will be some inflationary pressures through increased costs such as raw materials, packaging, energy and transport costs."
Heineken stock had gained 0.14% at 9:20 GMT, to change hands at €70.99 in Amsterdam. Shares have lost 8.32% in the past 52 weeks.
Carlsberg stock was up 0.49% at Dkr617 in Copenhagen, having gained 13.63% in the past 52 weeks.
The price increases paint a grim picture for the U.K. consumer who have to contend with higher prices on everything from food to electronics to toys.
December's annual inflation rate was estimated at 1.6%, according to data from the Office for National Statistics released last week. Last month, U.K. retail sales fell the most in more than four and a half years as consumers pulled back on spending amid rising inflation and broader economic uncertainty.
Retail sales fell 1.9% from the previous month, the ONS said, the biggest decline since April 2012 and much larger than the -0.1% dip anticipated by economists.
The Bank of England's target for inflation is 2% and it has said will have limited tolerance to go above the threshold. It is estimated that inflation could hit 3% as the U.K. begins the lengthy process of exiting the EU.
The central bank said it is keeping a close eye on consumer spending, as signs that households are dipping into their savings and are racking up debt to keep spending as inflation rises have started to show.
