Consumers are doing their Christmas shopping earlier in the year as growth in December has slowed in the past five years.
According to the Office for National Statistics, growth in December in 2012 and 2013 reached 16.6% and 17.6% respectively as consumers waited until December to do their Christmas shopping.
This non-seasonally adjusted growth rate slowed to 13.6% in 2014 as consumers started purchasing more goods in November, as Black Friday gained popularity in the UK.
In the three years since spending has evened out over the two months, dipping to 10.9% in 2015, 11.5% in 2016 and 11.2% in 2017.
The figures also revealed that online growth in textile clothing and footwear stores leapt by 20.9% year-on-year in the three months to December 2017.
The money spent in retail overall rose by 4.4 percentage points year-on-year.
Online sales of non-food products grew by 7.6% during the five weeks to 30 December following a “fashion frenzy”, according to figures from the BRC-KPMG sales monitor.
