Audiovisual specialist ProAV had another strong year in 2023, which it credits in part to continued growth in the workplace technology and video communications market in the wake of Covid.

This year, the Egham-based firm boasted its "strongest ever order book and pipeline for multinational opportunities".

ProAV's customer base spans the public sector, large enterprise and high-end residential segments.

The business is primarily focused on organic growth, derived from recurring revenues and lasting relationships in this space.
