Headlam Group's total revenue for the six months ended 30 June increased by 4.0% to £341.9 million compared with the corresponding period in the prior year.
On a constant currency basis, total revenue increased by 2.6% to £337.2 million with both the UK and Continental Europe delivering growth, and total revenue for each of the residential and commercial sectors also showing a positive performance.
The UK accounted for 85.9% of total revenue (87.0% in constant currency) with like-for-like revenue growth of 2.1% reflecting a positive performance from both the residential and commercial sectors, up 2.8% and 0.5% respectively.
Continental Europe, which accounted for 14.1% of total revenue (13.0% in constant currency), showed like-for-like revenue growth of 3.0%.
The group said the residential sector delivered strong growth of 6.7% whilst the commercial sector declined by 0.5% as the positive performance from both the Dutch and French businesses was offset by the Swiss business.
Gross margin across the company improved by 103 basis points to 31.06% compared with the same period in the prior year predominately as a consequence of the focus on more effective organisation and streamlining of the company's businesses' practices.
The company said it continued to trade in-line with the board's expectations for the full year.
