Built on the 2015 acquisition of Kelway, the UK arm of the world’s largest reseller claims to have 5,500 clients, including 30% of the FTSE 100.
UK accounts showing calendar 2024 revenues of £1.11bn may bely its true scale (its website cites a £2bn UK revenue number). The reported figure was down 1% amid a “more challenging trading environment” and a higher proportion of contracts where it netted down sales.

CDW UK&I is gearing up to invest in its local services offering via organic and acquisitive means, local MD Penny Williams told IT Channel Oxygen in July.
Boasting 13,000 staff globally, Nasdaq-listed CDW counts Apple, Cisco, Dell, Lenovo, HPE, Microsoft and Intel among its key vendors. Its international businesses in the UK and Canada were firing on all cylinders in 2025, growing collective net sales 9.1% year on year to $698.4m in Q3 as the global total advanced 4% to $5.7bn.
