OUR STORY
With a shared background in the events industry, Joshua & Charlie Karlsen founded OPUS 11 in 2018; in doing so, they established a new generation of luxury.

Innovative cuisine, expert mixology, and immaculate service, combined with the company’s strong ethos of loyalty, inclusivity, and respect, have fuelled the brand’s remarkable growth and undeniable success.
In 2026, OPUS 11 was proudly recognised as one of The Sunday Times Best Places to Work, a prestigious accolade that celebrates outstanding workplace culture and employee engagement. The award reflects the company's belief that exceptional experiences for clients begin with an exceptional team, recognising the environment of creativity, collaboration and care that continues to drive OPUS 11 forward.
Phenomenal food, master mixology, and immaculate service, combined with the company’s strong ethos of loyalty, inclusivity, and Respect.
WHAT WE DO
At OPUS 11 we have established a new definition of ‘luxury event catering’. Having built meaningful relationships with our clients, we develop creative menus through the artistry of exquisite food and master mixology, before delivering a unique event.
Our talented in-house chefs bring extensive experience from some of the world’s finest Michelin-starred restaurants, and our cocktails are created by the industry’s leading mixologists.
Meanwhile, our sister company, KALON 11, specialises in sourcing and training the highest standard of staff. Through our partnership, we hand-select the perfect team for every project. A unique attribute for any caterer.
Meticulous planning and an unmatched eye for detail allow you to focus on all other aspects of the event - a rare luxury for any host.
Sustainability
Sustainability has been at the heart of Opus 11 since day one, shaping how we operate, the partners we work with and the decisions we make every day.
We are incredibly proud to be B Corp certified, joining a global community of businesses committed to using business as a force for good. This certification recognises our commitment to high standards of social and environmental responsibility, transparency and accountability. More importantly, it provides a framework to continually challenge ourselves, improve our practices and make a positive impact on our people, communities and the planet.
This commitment is reflected throughout our operations. We prioritise local, responsible suppliers and work with like-minded brands such as Belu and Life Water to minimise single-use plastics. In our kitchens, we have removed unethically sourced produce from our menus, donate surplus food to The Felix Project and continue working towards our ambition of a zero-waste kitchen.
Beyond our kitchens, we are certified carbon neutral and support carbon offsetting initiatives benefiting local causes and charities. In 2022, we also transitioned to a fully electric delivery fleet, replacing our diesel vehicles.
CHARITY
We’re pleased with our commitment to donate a proportion of our profits to the Elton John Aids Foundation, as well as supporting other LGBTQ+ charities, and that our future success will continue to contribute towards their important work.
