The technology giant is moving the account for its Technology Solutions Group (TSG) to Burson-Marsteller.
Last year, Hewlett-Packard moved the European brief for its imaging and printing unit out of Porter Novelli in favour of Edelman.
Meanwhile, the company is reviewing its personal systems group PR – currently handled by Porter Novelli – across Europe (PRWeek, 4 February).
Porter Novelli had held the TSG account for six years.
Porter Novelli EMEA president Jean Wyllie said: ‘This decision was made at a global rather than a national level. We do not expect that it will have an impact on Porter Novelli’s UK workforce.’
Burson-Marsteller already handles the global and Europe-wide remit for TSG, which covers Hewlett-Packard’s enterprise products and services – including servers, storage and software.
The agency will now also handle all local market PR for the division.
