Reliable fuel solutions to keep your business running smoothly
Your data centre is only as resilient as its backup power systems and the fuel that supports them. Crown Oil Environmental’s specialist, tailored fuel services help safeguard continuity, ensuring critical operations run smoothly while reducing the risk of costly, unplanned downtime.
Power interruptions remain one of the leading causes of disruption across UK industries. If standby generators and their fuel systems are not fully prepared to take the load, even a brief outage can have serious consequences for both operators and customers. That’s why proactive fuel management is essential.
Call 0330 123 3399 to speak to a fuel expert and secure your backup fuel today.

Almost one-quarter of business generator failures are down to contaminated fuel, with IT downtime costing UK businesses around 300,000 hours per year (CA Technologies).

Fuel testing for data centres
Diesel fuel typically has a shelf life of up to 12 months. In standby generator systems, where fuel can remain dormant for long periods, even the highest-quality diesel will naturally degrade over time. This degradation can lead to sludge formation, microbial growth, tank corrosion and blocked filters or pipework, posing a serious risk to generator performance when power is most critical.
Regular fuel sampling and laboratory analysis are therefore a vital part of any data centre fuel management strategy. By routinely monitoring fuel condition, potential issues can be identified early, helping to maintain fuel integrity, protect critical assets and ensure your backup power systems perform reliably when called upon.
Fuel polishing for data centres
Fuel polishing, also known as fuel cleaning, is a vital service for data centres that rely on diesel-powered backup generation. It removes contaminants such as water, sludge, and microbial growth that can compromise fuel quality and lead to generator failure at the moment of need.
The process is completely non-disruptive and, depending on the level of contamination, can be carried out while your fuel remains in use. This allows data centres to maintain operational readiness and resilience while eliminating a critical point of failure within the backup power system.

Contracted emergency deliveries
Unplanned downtime impacts the vast majority of global businesses, and for data centres, even a short interruption can have critical consequences. Crown Oil Environmental’s priority fuel contracts are designed to provide complete peace of mind, ensuring rapid access to emergency fuel supplies in the event of power outages, fuel contamination, pipework blockages, misfuelling incidents, or any other issue that could threaten generator resilience.
Each contract is tailored to your data centre’s specific operational requirements. Your dedicated account manager will work closely with you to define site coverage, generator runtimes and service level expectations, creating a robust emergency response plan that supports continuous operation and protects uptime.

Fuel replacement for data centres
When diesel fuel has degraded beyond recovery, replacing it promptly is essential to prevent generator failure and avoid damage to critical system components.
Crown Oil Environmental’s fuel uplift service allows data centres to quickly and safely remove any quantity of contaminated diesel and replace it with a fresh, high-quality supply. This ensures your backup power remains reliable, protecting both your operations and your infrastructure from the risks associated with degraded fuel.
In-depth tank inspections for data centres
Regular tank inspections are a critical part of maintaining a reliable backup power system for data centres. Over time, tanks can develop corrosion, leaks or structural weaknesses, and pipework may become blocked or compromised – issues that can prevent diesel from reaching your generators when it’s needed most.
Crown Oil Environmental’s specialist inspections assess the condition of your tanks, associated pipework, and ancillary equipment, identifying potential risks before they lead to downtime. By proactively monitoring fuel storage infrastructure, data centres can ensure uninterrupted power availability, protect assets, and maintain compliance with industry and environmental standards.
