This York-based audio-visual integrator is currently working on a "groundbreaking" £5.5m project to enable physically distanced juries to take part remotely in High Court trials from ODEON cinemas in Edinburgh and Glasgow. A lack of fresh accounts means we have ranked Saville based on old calendar 2018 accounts, when it posted a £1.03m net profit on revenues of £43.6m. Following a rebrand last year, Saville has two units, ‘Visavi' and ‘Sparq', covering AV integration and live events, respectively.
