Pembrokeshire-based Celtic Quest Coasteering will be representing Wales at the National Chamber of Commerce Awards 2013.
The coastal adventure company are regional champions and national UK finalists for the Marketing Campaign of the Year award, as well as the Online Business of the Year award.
Celtic Quest Coasteering provides a first class coasteering adventure, exploring the Pembrokeshire coast while cliff jumping, adventure swimming, rock hopping and more.
Owner Cleopatra Browne said: "Starting out, we never dreamt we'd be representing Wales at such a prestigious event.
"Competing with the crème de la crème of the business world hugely reinforces our brand, not just within the activity tourism sector but British commerce as a whole."
Over 60 businesses from across the UK will be in attendance at the gala dinner on 28th November in London where the winners will be announced.
