Fuel Tank Integrity Testing

Fuel tank integrity testing is crucial in various industries, including automotive, aviation, and manufacturing, where fuel storage and transportation are involved. Fuel tank testing aims to ensure that the tanks are free from leaks or structural defects that could lead to fuel leakage, environmental hazards, safety risks, or inefficiencies in fuel consumption.

Network Environmental UK is a certified and accredited company for carrying out tank integrity testing. Our services facilitate a safe working environment and protect your valuable stock. Our skilled technicians are equipped with the most modern testing equipment to provide you with reliable inspections at highly affordable rates.

Fuel Tank Integrity Inspection

Our technicians employ NDT (Non-Destructive Testing) in the inspection and testing of fuel tanks to ensure their structural integrity and detect any potential defects or damage without causing harm to the tank itself. There are several NDT methods which we employ, including:

NDT testing for integrity testing of fuel storage tanks is conducted by our highly trained professionals who follow industry standards and safety protocols. A specific method or a combination of methods may be used depending on factors such as the tank’s material, size, accessibility, and the level of inspection required.

Safety Assurance & Environmental Protection

With our highly reliable fuel system integrity testing, we can help ensure the integrity of your fuel tanks, which is essential for safety. By conducting regular integrity tests, potential leaks or structural defects can be identified and addressed promptly, minimising the risk of fuel leakage, fires, explosions, or other hazardous incidents. Leaking fuel tanks can contaminate soil, groundwater, and surface water, posing significant environmental risks. Detecting and repairing leaks through integrity testing can reduce or eliminate the potential for fuel spills and environmental pollution.

Compliance with Regulations

Many industries, such as automotive, aviation, and petroleum, have specific fuel tank integrity regulations and standards. By availing of our tank testing and inspection services, you can ensure compliance with these regulations and avoid penalties or legal consequences. In the United Kingdom, there are specific legal requirements and regulations concerning fuel tank integrity testing in various industries, including:

  1. Health and Safety at Work etc. Act 1974
  2. Control of Substances Hazardous to Health (COSHH) Regulations 2002
  3. Road Traffic Act 1988
  4. British Standards (BS)
  5. Civil Aviation Authority (CAA) Regulations
  6. Environmental Protection Act 1990


We can ensure compliance with the laws and regulations related to your industry and ensure you are always safe from legal action or penalties.

Efficient Fuel Consumption

Fuel tank leaks or inefficiencies can result in the loss of valuable fuel, leading to increased operational costs. If tanks are not tested regularly, they may not be repaired in time and may eventually collapse. The build-up of corrosive materials can adversely affect your fuel quality and consumption.

By carrying out fuel tank integrity testing, we can identify leaks and other issues and help you optimise fuel consumption contributing to cost savings. Leaking or compromised fuel tanks can affect the performance of engines, generators, or other fuel-dependent equipment. By ensuring the integrity of fuel tanks, companies can maintain their equipment’s optimal performance and reliability.

Extended Equipment Lifespan

Fuel tank integrity testing allows for the early detection of structural issues, such as corrosion or material degradation. By addressing these issues promptly, the lifespan of fuel tanks and associated equipment can be extended, reducing the need for premature replacements. Regular integrity testing serves as a preventive maintenance measure, enabling proactive identification of potential issues before they escalate into major problems. This approach helps prevent costly repairs, equipment downtime, and disruptions to operations.

Reputation and Customer Confidence

Companies prioritising fuel tank integrity testing demonstrate a commitment to safety, environmental responsibility, and quality. This can enhance their reputation among customers, stakeholders, and regulatory bodies, increasing their confidence and trust in their operations.

Overall, fuel tank integrity testing provides numerous benefits, including improved safety, environmental protection, regulatory compliance, cost savings, equipment performance, and peace of mind for businesses and their stakeholders.


A fuel tank integrity test ensures the soundness of the fuel tank and points out any defects or potential defects that can cause loss and damage in future.

Different tests are run to ensure the tank’s structural integrity. These tests include:

  • Visual inspection
  • Non-destructive tests
  • Hydrostatic pressure test
  • Pneumatic pressure test

Not destructive tests that are carried out during the procedure include:

  • Ultrasonic Testing (UT)
  • Radiographic Testing (RT)
  • Liquid Penetrant Testing (PT)
  • Magnetic Particle Testing (MT)

We recommend carrying out the test every 5 years, whereas a thorough, in-depth integrity test should be done every 10 years.

The following factors are inspected during a fuel tank integrity test:

  • Overall tank condition
  • The area around and beneath the tank
  • Gauges and secondary containments
  • Venting and filling provisions
  • Signs of contamination
  • Installation compliance of the tank

An OFTEC-certified engineer should carry out a fuel tank integrity test to ensure thorough and reliable inspections as well as compliance with the safety regulations.
