Preventative Maintenance & Support

At FAIRFIELDS, we understand that asset reliability is critical in high-risk, high-consequence environments.

Unplanned downtime impacts safety, productivity and reputation. Our preventative maintenance and support services are designed to reduce risk, extend asset life and ensure your systems operate exactly as intended. From routine planned maintenance to rapid emergency response, we provide structured, data-driven support tailored to your operational priorities, giving you confidence that your infrastructure is protected long after project completion.

Every system we deliver is designed for long-term performance. Our support services ensure it stays that way.

We provide bespoke preventative maintenance programmes across mechanical, electrical, control and digital systems. These are built around the criticality of your assets, operational demands and compliance requirements. By combining structured inspections, calibration, software support and lifecycle planning, we help prevent failures before they occur.

Our teams support over 150 operational sites across multiple sectors , giving us extensive experience in maintaining complex, safety-critical infrastructure. Support agreements are tailored to your needs and can include scheduled preventative maintenance visits, remote diagnostics, 24/7 callout support, system auditing and obsolescence management.

Where required, we integrate mechanical and hydraulic expertise alongside control and software support, providing a truly multidisciplinary response. Our secure remote access capabilities allow rapid fault diagnosis, minimising disruption and reducing response times.

Preventative maintenance is not simply about servicing equipment. It is about protecting availability, improving reliability and giving your team the confidence that your systems will perform when needed most.

But what does it included?

Remote Diagnostics & Secure Access

We enable secure remote access to control systems, allowing rapid fault diagnosis and support without unnecessary site visits. This reduces downtime and ensures issues are addressed quickly and safely. Secure access is designed in line with industrial cyber security best practice.

Obsolescence Management

Control systems and automation components inevitably reach end-of-life. We proactively assess risks associated with ageing hardware and software, providing structured migration plans that protect availability and budget planning.

Functional Safety & Compliance

For safety-critical assets, routine validation and inspection are essential. Our TÜV-qualified engineers support ongoing safety validation, ensuring compliance with ISO 13849, IEC 62061 and IEC 61508 where applicable.

Cyber Security & Patch Management

Industrial systems require structured patch management and vulnerability monitoring. Our Industrial ICT specialists support secure lifecycle management aligned with ISA/IEC 62443 principles, helping you maintain both safety and security.
