The survey of 127 firms showed that whilst sales volumes grew at a slower pace than in the previous month - which benefitted from bumper Black Friday sales - the rate of growth remained healthy, and volumes were well above average for the time of year. Firm growth is anticipated again in the year to February.
Among the retail sub-sectors, growth was generally broad-based. Clothing reported the strongest rise in sales since February 2013, and robust growth was also seen from grocers, furniture & carpets retailers and other normal goods, such as jewellery and second-hand goods.
Internet sales volumes rose firmly again in the year to January, though the rate of growth eased off slightly for the second month running.
Wholesale sector sales continued to grow at a healthy pace, and are expected to rise further in the year to February, whilst motor traders saw more modest growth.
CBI economics director Rain Newton-Smith said: "After the sales bonanza of Black Friday cooled down, retailers saw solid footfall through the doors over the Christmas trading period, leading to further robust growth in sales in the New Year. However, under the spotlight of strong competition, some retailers are feeling the heat on their margins.
"Falling oil prices and low inflation mean consumers have a bit more money in their pockets. We expect to see this translate into strong sales growth in the months ahead."
