FLAME, Farnborough Hill School's Young Enterprise company, roared away from the rest in the Blackwater Valley heat of the competition.
The company has been producing and selling novelty candles since September.
All nine directors, dressed in black suits with corporate ties and badges, attended the presentation evening at The Sixth Form College, Farnborough.
They took four of the six awards available — the cup for the Best Business Plan, the Blackwater Valley Enterprise Trust Cup for the Best Report, the BAe Systems Shield for the Best Company Post-16 and the IT Services Cup for the Best Company Overall.
Flame goes forward to the regional finals in Portsmouth on May 20.
Faye Rodwell, a Flame director of sales and marketing with Claire Chitty, said of their big night: "It was really nerve-wracking but we had all put a lot of work into it so it all paid off.
"It (the competition) was of quite a high standard so we are really pleased with our results.
"We had our problems, as all businesses do, but we are pleased to have come through it and still be friends."
Viv Peters, Farnborough Hill's head of economics, said the lower sixth form girls' success was due to involving themselves from the start of the project, being extremely supportive of each other, their innovative approach and a willingness to listen to the customer.
She added: "We are extremely proud of the girls' achievement and wish them all the best for the regional finals."
The Young Enterprise scheme is organised by volunteers and gives students the opportunity to create and run their own company, giving them experience of working in the business world.
Advisers from Consignia and Forecourt Engineering assisted Flame.
