According to the study by the Office for National Statistics, Artificial intelligence in UK businesses: 2023 to 2026, the self-reported use of AI in organizations with 10+ employees reached 35% by June 2026, marking a new peak in AI adoption in the UK market.

Thankfully, businesses can overcome talent shortages by hiring third-party AI developers to provide strategic guidance, work alongside their internal IT specialists, or deliver AI-enabled software, either off-the-shelf or custom-built.
