Purchasing power decreased by 1.80% in 2019 compared to 2018. On average, you would have to spend 1.80% more money in 2019 than in 2018 for the same item.

In other words, £1 in 2018 is equivalent in purchasing power to about £1.02 in 2019.

The 2018 inflation rate was 2.48%. The current inflation rate (2018 to 2019) is now 1.80%^{1}. If this number holds, £1 today will be equivalent in buying power to £1.02 next year.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 2019 is 1,121.42. It was 1,101.59 in the previous year, 2018. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation.

Raw data for these calculations comes from the composite price index published by the UK Office for National Statistics (ONS). A composite index is created by combining price data from several different published sources, both official and unofficial. The Consumer Price Index, normally used to compute inflation, has only been tracked since 1988. All inflation calculations after 1988 use the Office for National Statistics' Consumer Price Index, except for 2017, which is based on The Bank of England's forecast.
