A number of U.K. health and consumer groups alike have long campaigned for the removal of sweets, chocolate and other high-sugar foods from the tills of supermarkets.
Linda Hindle from the British Dietetic Association said in a statement: "The 'pester power' at retail checkouts can lead to unplanned calories and contribute towards poor diet and health".
The groups are particularly worried about how the marketing of confectionery affects obesity levels in the U.K.
Dr Patricia Mucavele, head of nutrition at the Children's Food Trust, told CNBC via email: "In England, one in four children by reception (aged 4-5) are currently overweight or obese and this rises to one in three children by the time they reach Year 6 (aged 10) at school. Confectionery and sugary drinks are the main source of sugar intake in children".
Now they hope that other supermarkets will follow Tesco's all-out ban.
"We welcome [the move] very much but we think it's overdue. Now it's come we hope that all supermarkets will follow Tesco", Tam Fry, spokesman for the National Obesity Forum told CNBC in a telephone interview.

Earlier this year budget grocer Lidl removed all sweets and chocolates from its checkouts.
"Not only have we had exceptionally warm feedback to this move from the public but we have also experienced an increase in turnover of the fresh fruit, nuts and fruit juices that are now in place at our checkouts," a spokesperson for Lidl told CNBC via email.
While health concerns are an important factor, the rise of different shopping channels means that the value of checkout confectionery is likely to decline anyway, according to an analyst.
"We could see other supermarkets follow suit and one of the reasons why is the role of confectionery at the checkout is reducing" David Gray, retail analyst at PlanetRetail told CNBC in a telephone interview.
He said that the impact on sales will be limited because customers increasingly shop using e-commerce or self-checkout tills. As these grow in popularity they will reduce the opportunity for 'impulse categories' such as checkout confectionery.
