Doncaster-based plastic piping and ventilation systems firm Polypipe said on Tuesday its first-half revenue rose 6.2% tot £223.3 million with a strong contribution from recent acquisitions.

First-half profit before tax rose 4.3% to £31.4 million and interim dividend increased 8.1% to 4p per share.

Polypipe CEO Martin Payne said: “The business has performed well in the first half with good revenue growth and improved margins through selective cost reductions and acquisitions.

“The medium-term fundamentals of our markets remain strong.

“Whilst we are mindful of current political and economic uncertainty, management continues to focus on self-help measures and together with an encouraging start to the second half, the board’s profit expectations for the year remain unchanged.”
