Renault dealer Waters is moving from its current location on Comet Way in Hatfield back to the site it previously occupied on Lyon Way in St Albans.
Preparations for the move are underway in time for the official opening on August 28.
All of the existing facilities, including new and used Renault cars and vans as well as servicing, will be available to customers.
In addition, the new larger site will have a bigger service centre as well as more space for new and used Renaults on display. There will also be more customer parking available and a Class VII MoT station for light commercial vehicles and motor home owners.
Shaun Egan, dealer drincipal at Waters Renault, said: “We decided to move back to the larger St Albans site as the increased capacity meant we could accommodate the growing demand for Renault sales and servicing and further improve our levels of customer satisfaction.
“The St Albans site is just two miles away meaning there will be almost no disruption to customers, especially as the telephone number will remain the same. We will also be writing to all our customers to inform them of the new location.”
