Flexible WiFi provides fast, reliable WiFi for UK construction sites. We deliver enterprise-grade connectivity to site cabins, welfare units and outdoor areas — with rapid deployment, 24/7/365 support and connectivity that works even in low-signal locations using Starlink, 4G and 5G.

Construction site WiFi that keeps your project connected

From groundbreaking to handover. Fast setup. Reliable signal. Real support.

Most site WiFi is an afterthought

Off-the-shelf 4G routers that drop out. Patchy signal across cabins. Data costs spiralling out of control. CCTV that buffers. Project management tools that won't sync. And when it goes down, you're calling a helpdesk that's never heard of you.

Connectivity that keeps pace with your project

Construction sites are tough environments. Remote locations, temporary buildings, harsh conditions, and teams that need to be online from day one. We've deployed connectivity to sites across the UK - from city centre developments to middle-of-nowhere groundworks. We know what works.

Multiple connectivity options

No single solution works everywhere. That's why we deploy whatever gets you the best connection - bonded 4G/5G for urban sites, Starlink for remote locations, or leased lines for long-term projects. Typical speeds of 150Mbit/s minimum. We survey the site, test the options, and install what actually works.

With the rapidly evolving nature of the construction industry, and the heavy lean towards digitisation, relying on 5G routers simply wasn't enough anymore. We needed a robust, reliable, always-on connectivity solution that could keep up with the demands of modern sites. Safe to say Flexible WiFi have absolutely delivered on that. Their service ticked every box and then some.

We initially deployed Flex on our construction sites, but we very quickly brought them into manage our head office connectivity as well, creating a seamless connection between or remote construction sites and HQ. Instead of operating like isolated islands, our sites now function as true extensions of the head office.

Flexible WiFi has now become an essential part of how we build.
