NMGW becomes the third company to join the recently formed professional services consolidator, headed by mid-tier firm Levy Gee.
Earlier this week, the consolidator snapped up London firm Jayson Newman, also for an undisclosed amount.
Numerica is looking to build a national business services group and NMGW will offer it a presence in the South-West.
Tony Sarin, Numerica chief executive officer, said: ‘The acquisition of NMGW marks an exciting step in Numerica’s development.
‘Not only is this our first move towards regional expansion but we are pleased to have identified another firm that that shares our innovative and entrepreneurial culture and approach to business.’
NMGW is a six-partner practice formed in 1983 to offer service to entrepreneurial businesses.
