Family First, the fourth largest group in the UK, has acquired nursery group Kids Play to take it to 100 settings.
The group has bought three settings based in Milton Keynes, with one in Bury St Edmunds.
Former owner Paul Sharp said he is selling the nurseries after 17 years, as he and the group’s operations director are nearing retirement age.
Kids Play’s four nurseries provide 455 registered places.
The flagship setting in Milton Keynes known as ‘The Hub’ provides childcare for around 240 children, with a forest school, rooftop five-a-side pitch/activity area, and outdoor climbing wall.
