Yes, we offer comprehensive preventative maintenance contracts tailored to your specific requirements. These include:

• Scheduled inspections and performance testing
• Calibration, lubrication, and proactive parts replacement
• Priority emergency response with guaranteed SLAs
• Detailed asset condition reports and compliance documentation
• Extended warranty options

Contract holders benefit from reduced downtime, predictable maintenance costs, and documentation that supports PSSR, PUWER, and ISO compliance requirements.

We offer both options depending on the nature of the fault and your operational requirements:

On-Site Repairs: Many servicing tasks and repairs can be completed on-site by our mobile service engineers. This includes diagnostics, minor repairs, calibration, and commissioning—minimising downtime and avoiding the need to remove equipment.

Workshop Repairs: For complex overhauls requiring specialist equipment (torque testing rigs, pressure testing, PCB repairs), we transport units to our Leeds workshop. We can also provide loan units during extended repairs to keep your operations running.

We provide nationwide coverage across the entire UK. Based in Leeds (LS27), our central location enables:

• Yorkshire & North England: 4-hour emergency response
• Midlands & North West: Same-day service
• UK-Wide: Next working day for planned maintenance

For workshop repairs, we arrange collection and delivery nationwide. Our location on the M62/M1 corridor provides excellent logistics access to all UK regions.

CHP Actuation holds triple ISO certification, demonstrating our commitment to quality, safety, and environmental responsibility:

• ISO 9001:2015 – Quality Management Systems
• ISO 14001:2015 – Environmental Management Systems
• ISO 45001:2018 – Occupational Health & Safety

We are also Achilles accredited, ensuring we meet the stringent supplier qualification requirements for utilities and critical infrastructure sectors. Our engineers hold relevant industry qualifications for working in high-hazard environments including water utilities, nuclear, and oil & gas.

In most cases, repair is the cost-effective choice. Industry data shows that up to 80% of actuators considered for replacement can be successfully refurbished, with savings of 50-60% compared to new unit costs.

We provide honest, unbiased assessments with clear "Repair vs Replace" options, helping you make ROI-based decisions. Replacement is typically recommended only when:

• Repair costs exceed 70% of new unit price
• Spare parts are obsolete or unavailable
• Technology upgrades offer significant operational benefits
• The unit has fundamental design issues or repeated failures

All our repairs come with a 12-month warranty covering parts and labour. This demonstrates our confidence in the quality of our work and the components we use.

For preventative maintenance contract holders, extended warranty options are available. We use genuine OEM parts or quality-assured alternatives, and every repair undergoes rigorous testing before return to service—including torque verification and functional testing to manufacturer specifications.

Yes, we maintain a stock of common actuator models for loan during extended workshop repairs. This ensures your operations can continue while we complete the overhaul.

Loan unit availability depends on the specific model and current stock. We recommend discussing this requirement when booking your repair to ensure we can accommodate your needs. Contract maintenance customers receive priority access to loan equipment.

Our preventative maintenance inspections follow manufacturer guidelines and industry best practices. A typical inspection includes:

• Visual inspection for damage, corrosion, and seal condition
• Electrical checks (insulation resistance, motor current draw)
• Torque measurement and limit switch calibration
• Lubrication of gearbox and stem threads
• Functional testing (open/close cycles, position feedback)
• Handwheel and manual override verification
• Documentation and condition reporting

We provide detailed reports highlighting any issues found and recommendations for remedial work, enabling you to plan maintenance budgets effectively.
