The firm said in January that it had begun a strategy to boost annual profits by £500 million by 2021 by selling the same products in all the countries in which it operates, reducing costs and growing online sales more rapidly. Kingfisher has stores in France, Spain, Poland and Russia.
Sales for the six months were £5.479bn, up six per cent from £5.382bn.
Chief executive Véronique Laury said the strategy is going according to plan following a rise in sales in the UK and Poland:
"It has been a productive first half. We have delivered a good 'business as usual' result with both sales and profit growth. Performance has been driven by Poland and the UK, especially Screwfix, and a stable profit performance in France. This has been achieved alongside managing the start of our ambitious transformation plan, based on creating a unified company where customer needs come first.
"In the UK, the EU referendum has created uncertainty for the economic outlook, even though there has been no clear evidence of an impact on demand so far on our businesses. In France we remain cautious on the short term outlook.
"Looking longer term, we are starting to build solid foundations to enable us to deliver our five year transformation, which is our key growth driver. We are making good progress on our strategic milestones for this first year and we are on track. The level of transformation activity will increase significantly, however given the expertise and energy of our colleagues we continue to feel confident about the challenges ahead."
The company is spending about £70 million this year and £100 million next year to harmonise products.
Kingfisher said: "We have started unifying our offer, with the same products, presented everywhere in the same way. This will deliver significant customer benefits (newer products, higher quality, better sustainability, lower prices, simpler ranges, clearer merchandising and better packaging) alongside significant business benefits (higher sales, fewer SKUs, fewersuppliers, cost price reduction (CPR) and improved processes).
