UK retail promotions for consumer electronics and electrical products helped the categories "perform well" in June, says the British Retail Consortium (BRC).
However, TV sales were weak compared to 12 months ago.
The news comes as BRC-KPMG data shows that like-for-like UK retail sales values rose by 1.4 per cent in June 2013, while total sales increased 2.9 per cent.
Helen Dickinson, Director General at the BRC, said: "Despite challenging economic conditions continuing, June saw another strong performance from the UK's retailers, with very respectable overall growth across the categories. At this halfway point in the year we are able to see that sales are well ahead of the previous six month period, confirming that the retail recovery is continuing.
"Electrical and electronics promotions helped those categories perform well, although unsurprisingly we are seeing weak TV sales compared with last year when many people were upgrading their sets in order to watch the London Olympics."
The BRC also mentioned food, fashion, footwear, DIY and gardening products had a particularly strong month.
David McCorquodale, Head of Retail at KPMG, added: "This is another respectable performance by UK retailers. Sales are moving in the right direction, albeit hard-earned and promotion driven. The statistics are all the more creditable as last year's sales included a Jubilee boost.
"Periods of sunshine helped to lift the gloom on the High Street and retailers celebrated another month of rising sales."
