Brexit has had mixed effects. Negative impacts: reduced access to EU tech talent (EU workers now require visas); some companies relocated EU HQs to Amsterdam, Dublin, or Paris; initial loss of Horizon Europe funding (UK re-joined in 2024); and increased operational complexity for UK-EU tech businesses. Positive aspects: UK retained regulatory flexibility — particularly in AI, crypto, and financial services; the Global Talent Visa attracted international tech talent; and London has maintained its #1 European tech hub position throughout. Overall, UK tech has continued to grow strongly post-Brexit, though talent recruitment costs have increased.
