Smarter Building Retrofits for UK Facilities: Boost Efficiency, Cut Costs, Meet Net Zero
In the UK, where ageing infrastructure and rising energy costs pose mounting challenges, retrofitting offers a smart, future-ready solution.
Whether you're managing a Victorian-era school, a mid-century office block, or a modern mixed-use development, upgrading your building systems can unlock hidden performance and help meet increasingly stringent carbon reduction targets. With government incentives like the Public Sector Decarbonisation Scheme and growing pressure to comply with net-zero commitments, now is the time to rethink your building’s potential.
Smart retrofits not only reduce operational costs and emissions—they also enhance occupant comfort, improve asset value, and future-proof your property against regulatory shifts.

What comes to mind when you hear “smart building”? Perhaps sleek touchscreen panels or a holographic receptionist greeting visitors at the door. It’s a common image, and one that makes smart buildings seem like the preserve of futuristic tech parks or high-budget developments. But the reality is far more practical... and far more accessible.
The smartest buildings aren’t defined by flashy gadgets; they’re driven by intelligent systems working quietly behind the scenes. At Johnson Controls, we help buildings across the UK - from heritage schools to NHS facilities and commercial offices - achieve measurable improvements in comfort, safety and sustainability through targeted retrofits. And yes, they deliver real returns on investment. Here’s how.

Central Plant Optimisation:
Strengthen the core, elevate the whole Your central plant is the engine room of your building. It’s the primary source of comfort, the biggest energy supplier—and often the largest energy consumer. With Johnson Controls’ advanced optimisation software, powered by our OpenBlue digital platform, you can make it run smarter, deliver more comfort and consume less energy. Intelligent automation links systems and data to support better decision-making, reduce costs, improve reliability and accelerate your sustainability goals. Learn more >
Technology Refresh Solutions:
Because your building deserves better than patchwork fixes Outdated building management systems can slow everything down. Like walking uphill with a heavy load, they make daily operations harder than they need to be. Upgrading your BAS or BMS can dramatically improve efficiency, productivity and cybersecurity. Facilities teams across the UK are often stretched thin, relying on temporary fixes just to keep things running. A technology refresh gives your building the tools it needs to operate smoothly. Plus it gives your team the breathing room to focus on what matters. Learn more >
