The new modular design has a "bright, modern, clean" look with updated features, making it "easier and faster" to navigate and book holidays.
Leger Shearings Group’s web design manager, Katie Weale, said: "Following on from the Shearings website revamp late last year, the Leger Holidays site has also been refreshed, giving it a revitalised, contemporary look and feel.
"It’s a smarter, more personalised experience and agents will find it easier and quicker to help customers choose their holidays and make bookings on the spot."
Agents will also be able to access more destination selling points such as local attractions and food and drink highlights, as well as local currency, time zone and other tips and advice.
Personally tailored featured tours will also show on the main homepage, based on browsing history and searches.
