Motorway service areas have remained open during the coronavirus pandemic to support essential travel, but facilities have been limited.
Welcome Break said it has enhanced its hygiene and cleaning processes, and reconfigured the layout of its sites to enable social distancing.
Chief executive John Diviney said: "As the lockdown slowly eases and people around the UK gradually return to work, we are delighted to be opening up these great brands.
"It will provide a much-needed boost to those on the road and to support Britain working again.
"We very much look forward to welcoming back our returning customers.
"The health and safety of our colleagues and customers remains our absolute priority and we will continue to be guided by advice from Public Health England at all times."
