Centerprise added "significant production capacity" for PC building and configuration services in August 2022 via a £6m investment in a new facility in Caerphilly. Revenues slipped by 16 per cent in its year to 31 August 2021, amid a drive for more value-based business and supply chain constraints towards the end of the period, however. Known for its prowess in the MoD and public sector, the Basingstoke-headquartered outfit is a PC builder, reseller, recycler and services outfit, and also operates a £25m distribution arm.
