The nursery group now operates 214 nurseries offering more than 19,600 childcare places, consolidating further its position as the biggest provider of nursery places and early years settings.
Just Learning, which includes the brands Just Learning, Careshare and Nunu, provides around 6,700 places, with its 71 settings in England, Scotland and Wales. Most of the nurseries are rated 'good' by Ofsted.
Conservative MP Michael Fallon and entrepreneur Duncan Bannatyne established Just Learning in 1995. After Mr Bannatyne sold his share in 2001, the nursery chain acquired the Careshare nurseries in Scotland in 2003 and, following that, Nunu nurseries in 2009.
The move will give Busy Bees greater coverage across the North East and Scotland.
Marg Randles, Busy Bees' managing director, said, 'We are delighted to have acquired Just Learning; the nurseries are a perfect fit for Busy Bees. The acquisition demonstrates our confidence in the UK market.'
She added, 'Parents demand quality care for their children, and throughout the UK over many years Busy Bees has established an enviable reputation for its high standards.
'We have been working closely with the management team to ensure the handover is seamless for children, parents and staff. We will be keeping parents informed every step of the way, as we hope to further develop the excellent care, resources and services the nurseries currently offer.'
BUSY BEES: THE RISE OF A CHILDCARE EMPIRE
It reads like the script of a Hollywood blockbuster. How the founders of Busy Bees went from a converted house in Staffordshire to operating a multi-million pound nursery and childcare voucher business.
1983: Lynn and John Woodward and their friends Margaret Randles and David Thackery, unable to find the childcare they want for their children, sell their homes and move into a big house in Lichfield, Staffordshire, converting the downstairs into a nursery and moving into the upstairs flat. Most of the group had been teachers.
