In the UK, fats, oils, and grease (FOG) management is more than a best practice – it’s a legal and environmental responsibility. Failure to comply with regulations can lead to costly fines, reputational damage, and environmental harm. Here’s a practical guide for businesses to navigate FOG compliance effectively.
Understanding the Regulations
To comply with FOG regulations, UK businesses must understand the following key frameworks:
- Water Industry Act 1991
This law prohibits discharging substances, including FOG, that can damage or block public sewers. - Building Regulations Part H
Commercial kitchens are required to install grease traps to prevent grease from entering drainage systems.
- Local Authority Requirements
Councils often impose additional FOG management standards, requiring businesses to maintain systems and detailed maintenance logs. - BS EN 1825
This British Standard outlines performance and design requirements for grease separators, often serving as a compliance benchmark.
Common Pitfalls in FOG Management
Despite stringent regulations, businesses frequently fall short due to common mistakes such as:

Improper Installation: Using undersized or ineffective grease traps that fail to meet the demands of the kitchen.
Neglecting Maintenance: Allowing grease traps to overflow or clog due to infrequent cleaning or pump-outs.
Relying on Manual Methods: Outdated manual traps require constant intervention and often don’t meet modern standards.
Lack of Staff Training: Kitchen staff unaware of proper waste disposal practices, resulting in grease being washed down drains.
Non-Compliant Equipment: Using grease management systems not certified under BS EN 1825 increases inefficiency and risk of non-compliance.
Best Practices for FOG Compliance
To avoid these pitfalls and maintain compliance, businesses should adopt the following best practices:

Regular Maintenance Schedule
Ensure professional pump-outs and regular inspections to keep systems running efficiently. Maintain records for compliance audits.
Implement Staff Training Programs
Educate kitchen staff on proper disposal methods, such as scraping plates and avoiding pouring grease down sinks.
Install Advanced Grease Management Systems
Invest in AGRDs like Grease Guardian, which automatically separate and remove grease with minimal maintenance.
Conduct Regular System Performance Audits
Periodically review the performance of your grease management system to identify inefficiencies and implement improvements.
Partner with Experts
