PRWeek understands that selected UK agencies have been contacted by the Cambridge-based firm ahead of a plan to shortlist around four agencies to pitch for the business.
It is not clear what has triggered the quest although Napp wants to hold pitches within weeks, according to sources.
Napp, which was unable to comment before PRWeek went to press, currently works with Richmond-upon-Thames outfit Axon Communications.
Axon, which handles ‘corporate and brand' communications for Napp, said this week that its relationship with the company ‘remained ongoing'.
It added that it had ‘not received any brief from Napp at this point'.
