The origins of Wrightbus can be traced back to just after the Second World War in 1946 when the company was founded as Robert Wright & Son Coachbuilders in Ballymena Northern Ireland. Robert was joined by daughter Muriel, and son William. Robert Wright died in 1972. In 2017 William was awarded a Knighthood in the Queen's New Year's honors. Manufactured from the end of 2014, the integral constructed StreetDeck is built in both single and double-deck variations, the vast majority in the latter. At the time of writing the workforce stud at 770, but by the end 2022 that figure will be nearer one thousand. In 2021 70% of production was diesel powered, but in 2022 only 30% will be diesel, with the other 70% zero emissions.
