Neville Koopowitz, CEO at Vitality, said: "Britain's Healthiest Company provides a unique perspective as we are able to understand how the work environment directly impacts on employee health and productivity.
"What is clear is that companies which are concerned about employee wellbeing, and have a culture of health within the business, typically have healthier and more productive employees.
"Our research has also demonstrated the very significant role that modifiable risks play in employee productivity.
"One of the stand-out features of this year's survey has been the importance of sleep and the impact it has on both productivity loss and lifestyle behaviours.
"This all calls for employers to take a more active role in making their staff healthy.
"By investing in the health and wellbeing of staff, employers can rise to the productivity challenge in a more progressive, socially acceptable and relevant way for a service economy such as ours."
