BATHSTORE dampened the UK performance of builders’ merchant Wolseley after the retail chain posted a 15% slump in annual sales.

Wolseley, which is the world’s largest specialist distributor of plumbing and heating products, also took a £29m write-down to reflect Bathstore’s reduced value on its books.

The company said the chain, which it has tried to sell in the last year, faced “particularly challenging” trading conditions, but remained profitable.

Bathstore is the group’s only consumer-facing brand in the UK, trading alongside building supply operations such as Plumb Center.

Across the UK business, like-for-like sales were up by 2% in the year to July 31 and trading profits increased by £18m to £109m.

However, one-off items, including the Bathstore write-down, meant operating profits were £13m.

Wolseley also highlighted a weaker sales trend in recent months, with the final quarter showing a like-for-like decline of 2% on a year earlier.

Public sector activity, which represents about 25% of UK revenue, stalled in the second half, but the more resilient repair and maintenance sector, which represents about 65% of revenues, held up “reasonably well”.

Group pre-tax profits were £391m in the year to July 31 against a loss of £328m the previous year, while revenues increased by 3% to £13.6bn. That represents its first annual profit since 2008 and prompted the company to announce a return of its full-year dividend.

Chief executive Ian Meakins said the business was in good shape and that trends in August and September were similar to the end of the financial year.

However, he said: “Recent economic forecasts have weakened and over time this is likely to have an impact on our markets.”

The company has reduced its debt to £705m from borrowings of nearly £3bn seen in the aftermath of the 2008 credit crunch.

The turnaround process has seen tens of thousands of job cuts, an emergency cash call and a swathe of businesses closed or sold, including most recently Build Center in the UK. The group has also switched its tax base to Switzerland.

Keith Bowman, analyst at Hargreaves Lansdown stockbrokers, said that having restructured the group following the 2008 economic downturn, management again found themselves “facing gathering economic storm clouds.”
