After a challenging 2021 during which gross sales dipped, the US reseller's UK entity saw a recovery with sales spiking 7.5 per cent in its most recent set of results.

It attributes this to a continued focus on solutions and services, as well as growth in cloud gross sales.

It also credits a 9.5 per cent increase in operational expenses in the UK to this investment in its transformation programme.

Even so, thanks to ‘careful cost control', gross profit increased by 7 per cent and operating profit reduced by £1.2m to £9.2m, compared with £10.4m in the previous financial year.

A testament to its investment in cloud, in December, the global company announced the addition of "significant" cloud muscle to its arsenal with the acquisition of six-time Google Cloud Partner of the Year SADA for $410m along with a potential earnout of up to $390m.

Insight, which lists itself as one of the top one per cent of all Microsoft solution providers globally, said the deal puts it in the the same class as Accenture and Deloitte as one of three biggest cloud players for Microsoft and Google.

Insight has 22 Microsoft specialisations with more than 65 Microsoft Partner of the Year awards.
