The group posted a 70.6% rise in statutory pre-tax profits to £677 million as like-for-like sales in B&Q leapt 28.8% higher in the six months to July 31.
On an underlying basis, profits rose 61.6% to £669 million.
Like many other businesses and industries, we are facing significant operational pressures arising due to the pandemic, including product supply and availability, shipping and logistics, and cost price inflation
Kingfisher – which also owns the Screwfix chain – said it was facing mounting pressures on its supply chain, with costs and availability being affected, but stressed it was managing the issues.
It announced a £300 million share buyback and hiked its interim dividend on the back of a strong set of half-year figures.
The group has been boosted by a boom in DIY amid the pandemic, although sales have slipped in recent months as it comes up against tough comparisons from a year earlier.
B&Q sales soared 81.9% in the first quarter but fell 1.2% in the following three months and are 4.2% lower so far in the third quarter.
On a two-year basis, third quarter sales to date at B&Q are running 18.7% higher and 16.1% up across the group.
It said the performance is better than expected and upped its group-wide annual sales outlook, now forecasting a fall of between 3% and 7%, having previously pencilled in a drop of up to 15%.
The group said it is now set for underlying pre-tax profits of between around £910 million and £950 million, up from a market consensus of £913 million.
But it is facing supply chain headwinds, with costs rising for freight and raw materials and revealed it is still “below target product availability levels” in some categories – in particular timber and cement.
Kingfisher said it had been able to manage through the issues and UK lorry driver shortage, with stock levels gradually improving over the first half thanks to an early buying strategy, and expects to rebuild product inventory ahead of the peak trading periods.
Kingfisher said: “Like many other businesses and industries, we are facing significant operational pressures arising due to the pandemic, including product supply and availability, shipping and logistics, and cost price inflation, which have been managed effectively to date.”
It gave assurances that Christmas tree stocks are not set to be affected by the issues, with the group “well set up” for the festive season.
Thierry Garnier, chief executive of Kingfisher said: “Our industry is benefiting from new trends that we believe will be supportive over the long term.
“These include people spending more time working from home, the emergence of a new generation of DIY’ers, the need for greener homes, and a strong housing market.”
