The winners of the industry-recognised awards, which celebrate the top PR and communications professionals, were announced during a ceremony at the JW Marriott Grosvenor House.
The event saw Liquid recognised for its commercial achievements and response to the Covid-19 pandemic.
Liquid CEO, Elisabeth Lewis-Jones, commented: “After what has been a difficult 18 months of uncertainty for many businesses, we’re so proud to have been recognised for the strength of our business by being named ‘Best Agency Outside of London’.
“This award is testament to the determination, hard work, and exceptional talent within our team and the win was made all the better by being able to celebrate with colleagues and like-minded industry professionals in person at the awards ceremony in London.”
