He added: "Sales from both our catalogue and award-winning website at screwfix.com have also continued to grow and the recent addition of over 2,000 new products across more than 1,000 pages has highlighted our commitment to offering the best leading brands and exclusive products at value-for-money prices."
The business also introduced a new online search capability that helps customers to find what they are looking for more quickly and easily.
