About 200 vehicles will be supplied through the deal, covering Boxer, Partner and Expert vans over the next year, on a replacement cycle of about five years.
Funding is mainly through contract hire, with Interleasing the principal supplier.
Most vehicles will be used in Quadron's property services section, operation across the south of England. John Anderson, Quadron's corporate manager, said: 'We talked to a number of different manufacturers in our quest to find a company which could meet our requirements for a fleet of LCVs in a wide range of shapes and sizes.
'Peugeot stood out for several reasons, in particular the versatility and quality of its product range, the practicality of Boxer in terms of ease of loading and unloading and the excellent value for money the vehicles represent.'
