He first entered the British Touring Car Championship in 1996 where he campaigned a former David Leslie RML works 1993 Vauxhall Cavalier with his own low-budget Promotor-Sport Team. He started his season in the third round at Brands Hatch, but was well off the pace of his fellow Total Cup for Independents racers, failing to qualify due to steering issues. He returned for round 19 at Oulton Park, but did not qualify for a race until round 21 at Thruxton, finishing the first race, but retiring with gearbox failure in round 22. He would have more success on his second visit to Thruxton that year finishing 12th overall in the now historic race that saw Alain Menu and Will Hoy's crash in the Williams, Renault Laguna at Campbell on the opening lap. The last two championship races of the year at Donington Park saw Heward on the podium 2nd & 3rd in class and finishing the season's Total Cup in overall fifth place with 28 points. He returned to Donington Park in October that year for the International Tourist Trophy Race but retired due to engine failure. Despite his problems with the car, he returned with it for eight more rounds in 1997. Still a long way off the pace, he only qualified for rounds eleven and twelve at Donington Park. He only finished in the second of these races, four laps down from race winner Alain Menu. In 2010 Ian competed in the Bathurst 12 Hour in a Holden Commodore HSV and in the BritCar endurance series with ProSport. Ian is currently racing in the 2011/12/13 BritCar series in a 3400cc NissanRapier SR2. In 2016, Heward attended the Dunlop Endurance Championship in a Porsche 911 RSR racing for Porscheshop with Darelle Wilson. Heward returned to Britcar in 2018, racing in the 911 RSR with Darelle Wilson for Porscheshop.
