The Post Office has revealed that it is now the UK’s largest retailer open on a Sunday, with 3,800 branches trading seven days a week.

A recent transformation of the business has resulted in thousands of sites offering longer opening hours with the number open on Sundays up by 1,000 since 2013.

Research by the postal retailer found that nearly a third of people are more likely to use their local branch if it was open on a Sunday.

“I’m delighted that millions of people across the UK can now access Post Office services seven days a week. We are building a secure financial footing to maintain our services at the heart of communities for the future” said Kevin Gilliland, Post Office Network and Sales Director.

“Our modernisation plan is all about getting better for customers and making sure that branches across the country offer opening hours to meet their customers’ needs, with Sunday opening increasing rapidly across our network.”
