ExCel London came away with two gongs at the Exhibition News Awards, winning Best Venue Support and the Green prize.
The conference centre, which recently hosted the G20 summit, won the most awards out of the 12 categories at the ceremony at Indigo2 in London, which was attended by over 500 people.
Other winners included the Arena and Convention Centre Liverpool, which was named Most Effective Team and Stanco Exhibitions, which was awarded the Best Supplier/Contractor Support accolade.
The Bootleg Beatles and Elysium provided the entertainment at the third Exhibition News awards, which were voted for by readers of the magazine.
Representatives including suppliers, venues, contractors and organisers gathered to celebrate creativity in the exhibition industry.
Meanwhile, The Rheged Centre in Cumbria won the prize for best tourism venue of the year at last week's enjoyEngland awards.
The venue beat off competition from ExCel London and Loughborough University's imago conference and event brand to take the accolade.
