    OFTEC & CompEx-Certified Inspections

    Our certified engineers inspect fuel storage tanks, pipework, pumps, valves, filtration equipment, alarm systems and control systems, followed by a detailed OFTEC report on condition, compliance status and recommended corrective actions.

    Tank Gauge Installation & Calibration

    We install, programme, commission and calibrate tank gauges for real-time fuel level monitoring and high-level alarm protection, helping to prevent unnecessary fuel shortages or costly overfill incidents.

    Fuel Sampling & Polishing

    Stored diesel degrades over time through oxidation, water contamination and microbial growth. Our fuel polishing removes water, sediment, sludge, microbial contamination and particulates to keep emergency generators performing reliably.

    Water Leak Detection

    We design and install advanced water leak detection systems that monitor raised floors, plant rooms, air conditioning systems and pipework, alerting facilities teams or your Building Management System the moment a leak is detected.

    OFTEC & CompEx Certified Fuel System Inspections

    Routine inspections are essential for maintaining compliance, improving reliability and reducing the risk of equipment failure. Our certified engineers inspect fuel storage tanks, pipework, pumps, valves, filtration equipment, alarm systems, leak detection equipment and control systems, with a detailed OFTEC report provided after every visit.

    Tank Gauge Installation, Maintenance & Calibration

    Tank gauges provide real-time fuel level monitoring while activating high-level alarms to prevent overfilling. We provide installation, programming, commissioning, regular calibration, preventative maintenance, repairs and replacements to keep readings accurate.

    Fuel Sampling & Fuel Polishing

    Contaminated fuel can cause generator failure, filter blockages, injector damage and unexpected downtime. Our fuel polishing service removes water, sediment, sludge, microbial contamination and particulates, restoring fuel quality so emergency generators perform reliably during outages.

    High-Level & Bund Alarm Testing and Maintenance

    High-level alarms protect against tank overfilling, while bund alarms provide early warning when fuel escapes into secondary containment. We inspect and test alarm probes, sensors, control panels and system settings, plus carry out fault diagnosis, repairs and replacements to maintain environmental compliance.

    Water Leak Detection for Data Centres

    Water leaks are a serious threat to mission-critical environments. We design and install advanced detection systems covering raised and suspended floors, plant rooms, air conditioning systems, pipework and boiler rooms, with ongoing testing, maintenance and repairs to keep systems fully operational.

    Frequently Asked Questions

    Why is fuel system reliability critical for data centres?

    Data centres operate 24/7, 365 days a year, and even a brief power interruption can cause significant financial loss, operational disruption and reputational damage. Diesel generators only provide reliable backup power when the fuel infrastructure supporting them is properly maintained.

    What does an OFTEC & CompEx-certified fuel system inspection cover?

    Our certified engineers inspect fuel storage tanks, pipework, pumps, valves, filtration equipment, alarm systems, leak detection equipment and control systems, followed by a detailed OFTEC report on condition, compliance status and any recommended corrective actions.

    Why does stored diesel need fuel polishing?

    Stored diesel degrades over time through oxidation, water contamination and microbial growth, which can cause generator failure, filter blockages, injector damage and unexpected downtime. Fuel polishing removes water, sediment, sludge, microbial contamination and particulates to restore fuel quality.

    How does water leak detection protect a data centre?

    Our water leak detection systems monitor raised and suspended floors, plant rooms, air conditioning systems, pipework, boiler rooms and condensate systems, triggering alarms to facilities teams or Building Management Systems so leaks are caught before they cause damage.

    What is the purpose of tank gauges and high-level alarms?

    Tank gauges provide real-time fuel level monitoring, while high-level alarms activate to prevent overfilling. Regular calibration and maintenance help avoid unnecessary fuel shortages and costly overfill incidents.

    Do you provide fuel management for hyperscale, enterprise and colocation data centres?

    Yes. We deliver complete fuel management solutions across hyperscale facilities, enterprise data centres and colocation sites throughout the UK.
