Top Contech Companies in the UK | 2026

UK contech companies raised £57.1m in 2025 — the biggest year on record for the sector — and 2026 has opened even more strongly, with £38.1m raised through the first quarter alone. In total, contech companies in the UK have raised £259m across all equity fundraisings tracked by Beauhurst, with 94% of that total arriving since the start of 2020.

We’ve ranked the top 25 contech companies by total equity raised (all data sourced from the Beauhurst platform).

What is contech?

Contech — short for construction technology — covers the application of software, hardware, and materials science to the design, construction, and management of the built environment. It spans site-monitoring sensors, BIM and augmented reality tools, AI-driven project planning, low-carbon building materials, and platforms that digitise procurement, subcontracting, and site communications.

Beauhurst tracks 132 active contech companies in the UK, up from 44 in the final quarter of 2015 — a 200% increase over the decade. Together, these companies have raised £259m, with £242m of that arriving since 2020 (94% of the sector’s all-time total). The 15 companies reporting full financials generated £1.03b in turnover, and the sector supports an estimated 6,908 employees across the UK.

Key findings

• Converge tops the ranking with £41.0m raised. The West Midlands-based company develops sensors and real-time data analytics for construction sites, and accounts for 16% of all UK ConTech equity raised to date.
• XYZ Reality (£34.4m, London) takes second place with augmented reality tools for viewing 3D construction models on site, followed by Foresight (£28.6m, London) in project management software, nPlan (£28.1m, London) in machine learning for construction outcomes, and Qualis Flow (£14.4m, London) in IoT environmental monitoring. The top five account for 57% of all equity raised in UK contech.
• London hosts 12 of the top 25, followed by the South West (3) and the North East (2). The top 25 spans 11 UK regions in total — an unusually broad geographic footprint for a list of this size.
• Venture-stage businesses dominate the top 25 (16), followed by growth-stage (5), with two seed-stage companies and two exited businesses. Notably, no established companies appear in the top 25 — a profile that marks contech out as the youngest sector we’ve analysed, with the entire leading cohort still in active growth phase.
• The top 25 collectively raised £236m — 91% of the sector’s all-time total.

The future of contech in the UK

New contech company formations peaked in 2018 and 2019 with 13 and 14 new businesses respectively, before settling into a more measured 7 to 11 per year range. Investment trajectory, by contrast, has only accelerated. 2025 produced the biggest annual total the sector has ever seen at £57.1m, and 2026 has started more strongly still — £38.1m raised in the first quarter alone, already equivalent to 67% of 2025’s full-year total. Each of the last five years has set a new cumulative high, and 94% of all contech funding in the UK has landed since the start of 2020.

Digital site management is contech’s most heavily funded theme. Converge, XYZ Reality, Oculo, Contilio, BKwai, and SiteAssist all feature in the top 25, each building tools that bring software, sensors, or AI-driven analytics to what has historically been a paper-and-clipboard industry. The project planning and scheduling layer has produced some of the most-funded companies — Foresight, nPlan, and Aphex are using machine learning to forecast construction outcomes, track progress, and automate scheduling across complex multi-contractor builds.

A second distinct cluster centres on sustainable materials and decarbonisation. Vateris is reducing carbon emissions in concrete manufacturing, Low Carbon Materials converts plastic waste into construction aggregate, and Mykor produces mycelium-based insulation from industrial biomass. Alongside them, Kestrix and Qualis Flow are applying software to monitor energy performance and environmental impact — a response to the construction industry’s growing pressure to decarbonise. Finally, a third emerging theme is automation and robotics — Automated Architecture licenses robot-operated timber building factories to construction firms, and NavLive develops AI LIDAR scanning for building sites. Together these themes describe a sector still early in its commercial evolution but with clear investor momentum behind digital, sustainable, and automated approaches to building.
