Our Approach

When you choose Applied Industrial Systems as a systems design and integration partner, you can expect us to approach each project in a consistent way, in keeping with our four key values.

At all times, we aim to be:


Give us a problem to solve and we’ll identify an integrated solution that works – using a combination of in-house expertise, augmented with additional input from carefully selected specialist partners as required.


By becoming involved early in the project lifecycle, we can share our years of experience to influence user requirements and design specifications, plus work collaboratively with contractors to achieve the best possible final outcomes.


Approachable, agile and responsive, we work in accordance with the NEC3 framework of contracts to ensure the highest possible standards, across shared project objectives, can be achieved between all parties in the most cost effective manner possible.


As system integrators we take full responsibility for all aspects of integration required and we provide a holistic service from initial system design and build right through to ongoing maintenance management.
