European home improvement retailer Kingfisher downgraded its annual profit forecast by 7% today, after a drop in sales in Poland and France offset a pick-up in the UK and Ireland.

Kingfisher owns B&Q and Screwfix in Ireland and Britain and Castorama and Brico Depot in France.

It said that while the forecast cut reflected tougher trading in Europe, performance in the UK and Ireland, its biggest market which accounts for almost half of sales, improved.

British and UK consumers were “healthy”, chief executive Thierry Garnier said, helping first-half underlying sales rise 1.7%, with spending focused on “big-ticket” items like new kitchens, bathrooms and insulation.

“If you’re moving less, you spend more time to renovate and maintain,” Garnier told reporters, explaining the minimal impact on the group from Britain’s stagnating housing market.

In contrast, consumer sentiment in Poland and France was much weaker, he said.

In Poland, underlying sales fell 10.9% in the six months to the end of July, French sales were 3.8% behind, although a focus on cost helped profitability.

The group now expects pre-tax profit of around £590m for the 12 months to the end of January.

Shares in FTSE 100 group Kingfisher slipped 6% to 220 pence.

“The market consensus of the shares as a sell reflects little confidence in the group’s immediate outlook,” said Richard Hunter, Head of Markets at interactive investor.

CEO Garnier said inflation had peaked and he was encouraged by the ability to negotiate lower prices from suppliers in Asia, but weather during the period had not helped sales.

“In short, we never had great weather, it was too cold or it was too hot,” he said.

Kingfisher said confidence in future demand for home improvement supplies gave it the confidence to announce a new £300m share buyback programme starting in October.
