The thirteen weeks from March 27 to June 25 saw B&M's total group revenue up by 21.5% to £554.8m.
Despite this growth, like-for-like sales in the UK remained flat for the quarter, with the underlying LfL growing by just 1.7%. A dozen new stores were opened in the UK during the quarter, five in Germany from the pipeline of 50 new stores planned for the UK and 19 for Germany for the current financial year.

Bosses revealed the retailer was "on course to achieve market consesus profit expectations for the full year." They added: " The quarter had a slow start to like-for-like sales due to unseasonal weather and the timing of Easter compared to last year, but rebounded sharply in May. Current trading is stable, albeit our key seasonal category of Outdoor and Garden products fluctuates from week to week in line with weather conditions.

"The Group has satisfactory currency hedging in place through to the end of the important Christmas 2017 period. Ongoing exchange rate volatility may affect gross margin in FY2018 until we return to more stable general economic conditions."

Chief executive Simon Arora said: " Against a highly competitive backdrop, our robust and compelling retail business model delivered 21% growth over this first quarter. We have a well-defined and clear strategy for further growth and for B&M it remains 'business as usual' despite broader general economic uncertainty. Our outstanding value for money proposition to customers leaves us well-placed to continue to win market share."
