The move sees Mango Pie become the gallery’s first ever event management company.
Madolyn Grove, NPG's senior events manager, said: "Mandy Mahil and her team have worked with some of our high-level sponsors for over eight years, and in this time have brought to life a number of beautiful creative concepts that are unique to the gallery and our exhibitions.
"We are thrilled to have Mango Pie on our approved events supplier list and I am sure many of our clients will benefit from their services."
Amanda Rendle, senior events executive at corporate sponsor, Taylor Wessing, added: "We have been holding large events at the NPG as part of our corporate sponsorship for the past seven years, but it was only when we were introduced to Mango Pie this year that we saw how our budget could truly be maximised to bring some fresh ideas and creativity to the regular format.
"Mandy secured some fantastic catering, floristry and audio-visual which took our event to the next level and we are delighted that Mango Pie are finally on the approved suppliers list."
