Best Internet of Things Infrastructure Companies in United Kingdom
The 199 best Internet of Things Infrastructure companies in United Kingdom in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Telit Cinterion.
Ranked by disclosed equity funding and recent momentum, this directory maps 199 Internet of Things Infrastructure companies across the United Kingdom, collectively pulling $1.1B in total disclosed capital. No unicorns yet. But the funding is real, the field is crowded, and the gap between leaders and the pack is wide.
Balena sits at the top with $101M raised, followed by Eseye at $73M and IoTeX at $50M. Those three alone account for the bulk of the sector's disclosed capital. So what does that tell you? Concentration is the story here. I'd argue it reflects how capital-intensive the infrastructure layer genuinely is, particularly as hot themes like green infrastructure and cloud infrastructure demand longer runways and harder engineering. The sector's median install growth of roughly 13% year-over-year across connected internet and retail apps signals that demand isn't softening. Investors like Europa, Digital Catapult, and the EIC Fund are still writing checks, and with water infrastructure and safe water initiatives gaining regulatory traction in the UK, the next funding cycle likely rewards companies solving for resilience, not just connectivity.
