Supermarket giant Tesco was fined £500,000 at Liverpool Crown Court last week after a worker fell through a skylight roof at a store in Cheshire.

Contractor Tesco Maintenance was fined £300,000 while Tesco Stores was fined £200,000. The two must also jointly pay £9379 in costs.

On 13 June 2014, Andrew Burgess fell through the skylight in to the Tesco Express store and suffered cuts, bruises and muscle damage.

Craig Morris, prosecuting on behalf of the HSE, told Liverpool Crown Court that Burgess and three other workers were on the roof because of rain leaking into the store.

As the shop has a false ceiling, the skylights had been painted white along with the rest of the roof, but the skylights were not marked as fragile.

A colleague began marking around the skylights with yellow warning paint, but before he could complete the task Burgess fell through one of them.

According to the Liverpool Echo, the court also heard that workers had been on the roof at the premises on seven or eight occasions in the preceding five years.

Judge Steven Everett said it was “a minor miracle” Burgess had not been killed or seriously injured, but pointed out that it was the risk of harm that was the issue.

Tesco Maintenance pleaded guilty to two health and safety breaches and Tesco stores pleaded guilty to one breach.

A Tesco spokesperson said: “There’s nothing more important than the safety of our colleagues and customers, so we are extremely sorry this incident took place. As a result of the accident, we’ve enhanced the safety procedures used for this type of maintenance.”
