Counting London School of Economics and Burberry among its long-term clients, Egham-based ProAV bills itself as the UK's number-one audiovisual integrator. A lack of fresh accounts means we've had to recycle old numbers for its pre-Covid year to 31 March 2020, which show a £2.6m net profit on revenues that rose 10 per cent to £79m. Boasting satellite offices in Shanghai, Munich, Frankfurt, Dublin, Edinburgh and Birmingham, ProAV claims to have delivered over 700 projects outside the UK.
