The company is seeking admission to London’s main market, as opposed to AIM, becoming the first tech company to do so since 2011.
Servelec is wholly owned by Singapore-listed CSE Global, which is seeking to sell its entire holding in the firm.
The listing is expected to raise around £140m, constituting the largest UK tech float since 2010.
Tulchan Communications is handling comms on the float, with consultants James Macey White and Stephen Malthouse leading the account alongside analyst Sam Chiene.
The announcement comes as Tulchan works on the £3bn mega-listing of London Eye and Madame Tussauds owner Merlin Entertainments.
The firm, currently owned by private equity giant Blackstone Group, is expected to complete its listing next month.
