It warned that like-for-like growth would slow in the second half, predicted that underlying demand would remain strong.

Chief executive David Williams said: ‘Like-for-like sales were 12.5% up in the first half, reflecting favourable comparables following a strong cocktail of positive factors.

‘We’ve outperformed the market quite significantly,’ he said. ‘I would single out insulation as being a very important contributor to the group’s performance in every area in which we trade.’

The company has benefited from the government’s Building Schools for the Future programme and a booming office market.

But Williams said of the coming year: ‘Our concerns are about macroeconomic factors and whether the uncertainties in financial markets do or do not spill over into the wider economy.’
