DHP has tested the scheme for the past six months at its Rock City venue in Nottingham and the Thekla in Bristol.

Drinkaware crews work in pairs and “wear branded uniforms to ensure they are easily spotted by vulnerable people seeking help which can include reuniting friends; helping people to taxis or providing comfort to customers in distress,” the announcement states.

Nottinghamshire police chief inspector Mark Stanley said that “from a policing perspective, we've already seen a positive impact since the launch of the scheme at Rock City where we’ve seen some great examples of crew intervening early to resolve matters adding to a more vibrant, safe venue, and I would strongly encourage other venue operators to consider coming on board too.”

Thekla General Manager Alex Black added: “We’ve had incredible feedback from other management and customers, we are definitely going to keep the Crew on board because it frees up time for management and security and increases the safety of our customers.”

Drinkaware also offers e-learning courses for bar staff, teaching them how to spot alcohol-related vulnerability and harassment and offering practical advice.
