Consumer spending held up in April, with record growth online, official figures show.
Total sale were flat but that defied analyst expectations of a 0.3% decline, the Office for National Statistics (ONS) said.
In the three months to April, volumes rose by 1.8% compared to the previous three months.
Rhian Murphy, the ONS's head of retail sales said: "Retail growth was strong in the three months to April with a record quarter for the online sector, driven mainly by clothing purchases, with warmer weather boosting sales. Elsewhere, department stores continued to see their sales fall."
All sectors except department stores and household goods stores showed growth in the three-month period. Department stores suffered from store closures since last year, with sales dipping 0.5%, while household goods stores saw a 2.9% decline.
But this was offset by growth across several other sectors. The biggest contributor to the rise was non-store retailing, growing by a record 9.4% in the period.
The ONS said non-store retailers, which mostly consists of online-only brands, had deployed a range of promotions and sales.
In April, online retailing accounted for 18.7% of total retailing compared with 17.7% in the same month last year.
Philipp Gutzwiller, head of retail at Lloyds Bank Commercial Banking, said: "A fourth consecutive month of sales growth, buoyed by exceptional weather over the Easter bank holiday weekend, will have no doubt helped further boost the confidence of retailers across the UK."
Guy Foster, head of research at Brewin Dolphin said: “UK consumers decided to keep calm and carry on shopping. Political concerns seem to be as grave as ever but the economy is close to full employment, wages are growing and inflation remains low. These are ideal conditions for shoppers. Perhaps an impotent government means less chance of it messing things up."
But Lee McDarby, corporate IP managing director at Moneycorp, said the figures provided little sunshine for the high street.
"The surprisingly upbeat retail sales figures are down to sustained online spending, perhaps boosted by falling unemployment," he said.
"A close look at the detail shows high street chains and department store sales are struggling, reflecting the store closure and job loss headlines we've seen recently."
