B&Q owner Kingfisher has hiked its annual profit outlook despite flagging half-year sales in the DIY chain as Britons held off from splashing out on bigger purchases.

The group said B&Q like-for-like sales in the UK and Ireland dropped 1.8% over its second quarter, with sales of so-called big ticket items plunging 8.1%, driven largely by lower demand for bathroom ranges.

But the decline marked an improvement on the 4.1% fall seen in the first quarter across B&Q, as heatwaves sparked a recovery in demand for seasonal items.

Its Screwfix business also continued to see strong sales, with a 7.1% jump in the second quarter, helping overall UK and Ireland same store sales rise 1.6% in the second quarter and 0.4% over the first half.

Kingfisher โ€“ which also has a number of home improvement brands across Europe, such as Brico Depot and Castorama โ€“ reported a 9.9% rise in underlying pre-profits to ยฃ404 million for the six months to July 31, though this was boosted by a one-off ยฃ14 million UK business rates refund.

On a statutory basis, pre-tax profits jumped 18.4% to ยฃ400 million.

The group increased its guidance for full-year underlying pre-tax profit guidance to between ยฃ595 million and ยฃ635 million, up from the ยฃ565 million to ยฃ625 million previously pencilled in.

Outgoing chief executive Thierry Garnier said: โ€œWhile the consumer environment remains mixed, our consistent delivery, strategic progress and opportunities ahead give us the confidence to upgrade our guidance.โ€

Mr Garnier announced plans in May to step down after nearly seven years to head up Netherlands-headquartered supermarket group Ahold Delhaize, but is remaining in place during the hunt for his successor.
