One Platform, Total Control — Why Challis Ag+ AssetBook Is a Game-Changer for Building Management
Introduction
Let’s be honest — managing a building used to be simpler. One boiler, a few lights, a security guard on the front desk. Now? It’s all gone smart. Lighting, heating, door access, air quality monitors, EV chargers, CCTV, occupancy sensors, and water systems — all feeding data from every corner of your estate. It’s incredible tech… but most of it lives in silos.
So while the tech gets smarter, management often gets harder.
That’s where Challis Ag+ AssetBook comes in.
It’s the UK’s only software platform that unites every Building Management 
System (BMS), smart device, and IOT control across your entire estate — old or new — and presents it all in one seamless, easy-to-use interface. Designed with direct input from real facilities managers, it’s the system the market has been waiting for.
In this guide, we’ll explore why AssetBook is truly unique, what it can do, and why local NHS Trusts and commercial estates are already seeing the benefits.
IMPORTANT: Other Software Platforms that you are considering are already outdated
1. The Power of One Platform
You know the drill. A dashboard for HVAC. Another login for CCTV. A separate app for water system alerts. And when there’s a compliance audit? You’re pulling data from five different places and hoping they all line up.
Challis Ag+ AssetBook ends that.
It brings together every critical system — including IOT sensors, smart meters, and existing BMS installations — under a single cloud-based platform. That means:
- One login
- One reporting dashboard
- One control centre
Whether you’re managing a hospital estate, a school network, or a portfolio of commercial buildings, you get full oversight and total control from day one.
You don’t need to replace your existing systems — AssetBook works with what you’ve got.
And that’s the magic. It connects to your existing estate tech and instantly makes it smarter, more efficient, and easier to manage.
Any system that doesn’t offer this level of seamless integration is now officially out of date.

3. Why It’s the Only System of Its Kind
Let’s be clear — there are plenty of platforms that promise integration. But they either:
- Only work with specific hardware,
- Require ripping out your existing systems,
- Or offer basic data viewing without real control.
Challis Ag+ AssetBook is different.
It connects, controls, and reports across new and existing tech, regardless of manufacturer. Whether you’ve got Siemens BMS in one building and Honeywell in another — it works. Whether your tap systems are brand new or ten years old — it works.
There is no other software platform currently available in the UK that integrates, controls, and automates this wide a spectrum of building systems into one unified solution.
That’s not marketing talk. That’s fact.
4. Simplicity Meets Sophistication
You’d expect something this powerful to be difficult to use. It isn’t. The interface is clean, modern, and intuitive.
- Drag-and-drop reporting
- Simple widget dashboards
- Filter by site, building, floor, or room
- Colour-coded alert statuses
Even non-technical users can get to grips with it in minutes.
Your FM team won’t need weeks of training or outside consultants. It’s all designed to be plug-and-play from the moment it’s installed.
5. Built on Listening: Designed for You
Challis AssetBook wasn’t dreamed up in a boardroom. It’s the result of years of listening to facilities managers, engineers, and estates teams across the UK.
Every feature has been included because someone like you said, “I wish we had a system that could…”
So we built it.
And we’re still building. Updates are regular, feedback-led, and responsive to emerging challenges. Whether it’s adapting to new NHS guidance or making carbon reporting even faster, we’re always ahead of the curve.
Conclusion: The Future is Integrated
There’s no shortage of building systems out there. But there is a serious shortage of systems that bring it all together.
Challis Ag+ AssetBook is the only platform that truly unifies control, compliance, and reporting across every smart system in your estate.
Any system that doesn’t offer this level of seamless integration is now officially out of date.
It works with the assets you already have. It adds powerful features you didn’t know were possible. And it saves you time, money, and endless hassle.
That’s why every local NHS Trust around you is already using us.
