Regular Inspections

Tank Repairs, Maintenance & Interior Cleaning

Regular inspection and maintenance of oil and diesel tanks is essential for preventing leaks, contamination and costly failures.

We strongly recommend annual inspections, particularly for older tanks or those exposed to harsh weather conditions. These checks help identify early signs of wear, damage or non-compliance before they become serious problems.

We also offer interior cleaning and sludge removal, which helps protect boilers, generators and fuel systems from damage when tanks have accumulated water or sediment. Interior cleaning of tanks is typically required when water and sludge contamination is detected. This happens when filters are repeatedly blocking, fuel quality issues occur or when tanks are being decommissioned or re-commissioned.

We also carry out tank repairs, such as replacing damaged or leaking fittings, lids, caps, and inspection hatches, fitting new valves, outlets and isolation points, repairing pipework connections and other minor structural issues.

If a repair is not cost-effective or compliant, we will explain your options clearly and advise on suitable replacement tanks from our range.
