Liverpool Town Hall has appointed Carringtons Caterers, which is based in Skelmersdale, as the preferred food and drink provider.
The previous contract for catering at the venue was awarded in January 2013 to Kudos.
Directors Helen and Darren Wynn and their team of more than 50 staff will cater for functions at the 18th century Grade I-listed building.
Carringtons will now be on hand at a varied selection of events to be held at the Town Hall, including conferences, gala dinners, weddings and award ceremonies.
Helen Wynn said, 'We are delighted to be working in affiliation with the Town Hall - it brings us great pleasure to have been selected by such an admired Liverpool landmark.'
Steve Gibbs, Liverpool Town Hall and civic manager at Liverpool City Council, added, 'It is wonderful to have joined forces with a catering company that shares a similar ethos to ours.
'We hope that this new partnership will increase our already extensive list of private occasions, and offer a truly memorable and unique experience to our guests.'
