Founder Julia Willoughby is changing role after nearly 16 years at the helm. She will become CEO while Jane Ainsworth will act as MD, effectively taking control of the agency.
At the same time Willoughby has lost its Glen Dimplex Home Appliances account to Lucre Communications following a four-way pitch. It held the account for four years. Fees are believed to be more than six figures.
Leeds-based Lucre will now handle the consumer and trade PR for the company.
Deputy MD Jo McCarthy said: 'We were sad to lose the GDHA account as we had delivered some fantastic results for the cooking brands during our time working with them.'
GDHA manufactures cooking appliances Belling, Stoves and New World, and refrigerator brand Lec.
Lucre is to promote awareness of the brands' cooking and refrigeration ranges.
