The Keycamp brand is to be dropped in favour of sister operator Eurocamp, which will be sold through the trade for the first time.
Previously, the sister European camping brands were marketed separately to the trade and direct to consumers by parent Holidaybreak, bought by Cox & Kings in 2011.
National sales manager Michelle Betley-Jones said the move would enable the company to pool resources behind one brand.
The company plans to maintain commission levels and continue its strong relationship with agents, she said.
It is launching its biggest TV campaign to date to promote the Eurocamp brand on Boxing Day.
Betley-Jones said the companies had both been operating profitably but research had shown the Eurocamp brand was more widely recognised.
“They have been sister companies for more than 15 years and are very successful. This wasn’t a snap decision,” she said.
The move means agents will now have access to a further 74 parks, new destinations such as Sardinia, the islands of Elbe and Il De Re, and ‘safari’ tents, previously exclusive to Eurocamp.
A trade portal Eurocamp4agents.co.uk will go live next month along with a raft of agent incentives.
A brochure, due out in December, will showcase new luxury mobile homes for 2014 called Aspect holiday homes. These have a covered decking area plus dishwashers, Wi-Fi and iPod docks.
Also new is a sub-brand called Eurocamp Active offering outdoor sports such as cycling and climbing.
