Survey and fuel testing

Identify issues early and protect your fuel systems

If you’re experiencing fuel problems or your tank is showing signs of age, a professional survey and fuel testing service is essential. At 1st Industrial & Commercial Services, we help identify potential issues before they become costly failures—keeping your systems safe, compliant, and fully operational.

Why Fuel Testing Matters

Fuel tanks are often out of sight, making it easy to overlook deterioration. However, hidden issues such as corrosion, leaks, or poor containment can lead to serious environmental risks, operational downtime, and potential fines or prosecution.

Modern fuels, particularly those with biodegradable content, are more susceptible to microbial growth and fuel degradation. Without regular monitoring, this can lead to:

  • Tank corrosion and structural failure
  • Boiler injector and fuel pump damage
  • Blocked systems and reduced efficiency
  • Loss of heating, hot water, or power

A simple, proactive inspection and testing plan can prevent these issues entirely.
