We’re not just builders, we think like business owners, and we build like the bottom line depends on it.

Demand for high-performance data infrastructure has never been higher, driven by the rise of AI, cloud adoption, and automation.

Rising energy costs, tightening regulations, and the pressure to meet ESG targets are forcing property investors and commercial developers to rethink how data infrastructure is built. Many struggle to find partners with the technical skill and commercial understanding to deliver future-ready, energy-efficient data centre builds in London. At Craftex, we step in where others fall short, bringing precision, speed, and deep project leadership to complex commercial environments.

We design and deliver AI-ready facilities built around operational goals, not guesswork. Our approach blends early-stage planning, in-house technical expertise, and a tight-knit network of proven subcontractors to drive projects from paper to full operation without delays. Every phase is handled with direct oversight, aligning build quality with performance demands and long-term value.

The result is faster handover, reduced energy consumption, and dependable cost control. Our clients avoid compliance risks, unlock investment value, and gain durable, low-maintenance assets. Projects are tailored to fit site, strategy, and scale, without the usual trade-offs.

We help clients plan and execute low-power server facilities tailored to performance, budget, and future scaling. Our team manages every detail from design to final fit-out, ensuring reliability and long-term value.
first time trying this for a new commercial site build. The pricing fell within the range we expected and nothing came up mid-project to shift it. Results were solid clean install tight timelines and a professional team from start to finish. I'd give this 4.7 stars. Definitely recommend if you need something that just works without the usual runaround.

last year we used a bigger firm with flashy designs but they missed two deadlines and kept bouncing us between project leads. this time the communication was consistent and the timelines held. even when we changed specs mid-way they adjusted without delay. the result was better than expected. pricing stayed within budget and nothing felt rushed or half-done. project finished 5 days early and all systems passed inspection. i’d rate this a 4.8 and yes we’ll be using them again.

If you need strong delivery and technical follow-through this is a smart choice. Works best when you want minimal disruptions and fixed timelines. Would recommend this for commercial sites or tech infrastructure upgrades.

structure rated 4.9 install process 4.8 site coordination 5. project clarity 4.7 support after handover 4.9. definitely dependable and sharp with timelines. worth booking early.

sometimes speed matters more than scope and this fits that need. if your priority is tight handover control and site clarity this works. not flashy just delivers. better for complex builds with commercial focus or multi-use goals. would choose this again on any AI-linked or logistics-centred development.
