Housein will be responsible for the UK holiday specialist’s trade strategy across its three brands – Butlin’s, Haven and Warner Leisure Hotels.
He had been with the business for 15 years and will be supported in his new position by national sales manager Louise Tansey and trade marketing manager Krishna Thakore, who will continue in their current team roles.
Bourne’s former head of travel trade Neil Davies left the company in December.
Housein said: “Trade sales is an extremely important area of our business and produces excellent results, so my main aim is to continue to drive this forward with the support of Louise, Krishna and the rest of our experienced team.
“We have some exciting plans in place for this year and beyond and I’m keen to build on our already excellent relationships with the trade.”
