Opun was established in 2014 and aims to improve home improvement experiences by combining leading-edge software, trade experience and expertise and customer guarantees.

In a strategically important move, Aviva has agreed to back Opun by investing £3m in three tranches, subject to achievement of milestones.

Fieldfisher's team was led by corporate director Guy Burman, supported by associate Julian Grant and tax partner Mark Gearing.
