Edgecombe – who starts on Monday – will report to LSC head of external communications Sue Ashe.
‘We are building the B2B and corporate team, and Laura will be key in reviewing the LSC’s communication of key business sectors, including automotive, health care and manufacturing,’ said Ashe.
The LSC has also added to its list of recent agency hires and appointed Hill & Knowlton on a corporate remit.
H&K corporate director Suzanne Prance will head a team of four and report to Ashe.
The appointment followed a four-way-pitch, which included incumbent Grayling.
The LSC is responsible for all post-16 education in England outside universities.
