Though no longer the largest VAR in the UK, this LSE-listed giant has become a formidable player on the international stage.

According to a 30 January 2023 pre-close trading update, Computacenter's total top line is set to top £9bn in 2022 (a 30 per cent hike), putting it in the same league as US-based powerhouses WWT, SHI, CDW and Insight.

That's thanks mainly to a North American M&A drive that's taken in FusionStorm (2018), Pivot (2020) and Business IT Source (July 2022).

With Computacenter yet to release audited 2022 full-year numbers at the time of publication, we have had to rank it on 2021 figures showing UK gross invoiced income of £2.064bn.

Computacenter's domestic business remained on course for both top and bottom-line growth in 2022, it stressed in its interim results in September, however. That's despite first-half revenues dipping 7.1 per cent annually on the back of a "dampening in demand for hardware".

Though still around half the size of CDW, Computacenter claims it holds an important edge over the competition, namely that it is "the largest services business of any value-added reseller" and "the largest value-added reseller capability of any services business worldwide".

The FTSE 250 firm is "as bullish as we have ever been about our target market and competitive positioning," it said in its January updated.
