Building materials and DIY group Grafton said its revenue for the six months to the end of June jumped by 8.6% to £1.45 billion.
In a trading update, the Irish-headquartered company said its trading pattern was heavily influenced by the weather.
It said the hot and dry weather in May and June benefited a number of its businesses, particularly the Woodie's brand in the Irish market.
Gavin Slark, the company's chief executive, said Grafton's businesses in Ireland and the Netherlands continue to perform well.
"In the UK, the Group's growth has been influenced by the Selco store opening programme and the acquisition of Leyland SDM in February, where we are pleased with progress to date," he said.
"We enter the second half well placed to deliver our expectations for the financial year," he added.
Half year revenues at Grafton's Irish merchanting division rose by 10%, while turnover at its UK merchanting division increased by 6.7%.
Meanwhile, revenues at its retailing operations jumped 15.8% while revenues at Grafton's manufacturing division jumped 21.1%.
