Regulatory Requirements for Spill Kits & Bunding in the UK
Effective spill prevention is not just a matter of good housekeeping, it is a critical legal and environmental obligation for businesses across the United Kingdom. Whether you are managing a construction site, a manufacturing plan, or an agricultural facility, the way you store and handle hazardous liquids. This includes oil, fuels, and chemicals - all of which are subject to strict regulatory scrutiny.
Failure to implement adequate containment will often lead to devastating environmental damage, catastrophic clean-up costs and severe legal penalties. With the Environmental Agency and other UK regulators now increasing their focus on pollution prevention, understanding your responsibilities regarding spill kits and bundling is essential for maintaining a compliant and safe operation.
Why Spill Prevention Compliance Matters
In the UK, the "polluter pays” principle is firmly embedded within environmental law. If a leak or spill from your site enters a watercourse, groundwater or even the soil, then your business is liable for the consequences.
Pollution risks: Even small volumes of oil or chemicals can cause massive levels of groundwater or even kill local wildlife.
Environmental Liability: Under the Environmental Protection Act 1990, businesses have a duty of care to manage waste and prevent pollution.
Financial impact: Fines for water pollution can be unlimited, and the costs of a professional environmental remediation will often far exceed the initial investment in prevention.
Employee safety: Proper containment reduces slip hazards and exposure to toxic substances that align with COSHH (Control of Substances Hazardous to Health) Regulations.

Are Spill Kits A Legal Requirement
While there is no single “spill kit Act” several pieces of legislation make having them a practical legal necessity. The control of pollution (oil storage) (England) regulations 2001 and equivalent rules in Scotland, Wales and Northern Ireland dictate how much oil must be stored. As well as this, the EA’s pollution prevention guidelines identify spill kits as “best practice” for any site storing any hazardous liquids.
Who needs a Spill Kit?
If your business operates in any of the following sectors, spill kits are essentially mandatory to meet your legal duty of care.
- Construction & Demolition: For plant machinery and fuel bowsers
- Agriculture: For pesticides and red diesel storage
- Manufacturing & Warehousing: Wherever IBCs or drums are handled
- Transport & Logistics: For vehicle maintenance and fuelling stations
Typical Spill Kit Contents
A compliant spill kit is more than just a bucket of sawdust. It should include key elements such as:
- Absorbent Pads & Socks: To soak up and contain the spread
- Drain Covers: To prevent the pill from entering the sewage system.
- Personal Protective Equipment (PPE) : Nitrate gloves and goggles
- Disposal Bags: Clearly marked for hazardous waste
- Building and Secondary Containment Regulations
Bunding is the primary line of defense in spill containment. A bund is a secondary containment system - essentially a “tub” or wall - designed to capture leaks as well as catastrophic failures from primary storage tanks, drums or IBCs.
The 110% Capacity Rule
UK law is very specific about bund capacity. To be compliant, a secondary containment system must be able to hold:
- 110% of the maximum capacity of the largest container within the bund
- 25% of the total aggregate storage capacity if multiple containers are stored together
The extra 10% is a safety margin designed to account for “surging” during a tank failure, to accommodate rainfall in different outdoor installations.
Key Bunding Requirements
Impermeability: The bund needs to be made of materials (like concrete or high-density) polyethylene) that are resistant to the substance being stored
No Outlets: A compliant bund should not have a drain valve or any opening in the walls or base that could allow liquid to escape.
IBC Spill Pallets: For mobile storage, IBC spill pallets and drum sumps are recognized as a key form of secondary containment - provided they meet the 110% capacity rule.
Environmental Agency Expectations
The environment agency expects businesses to have a pollution incident response plan. This plan should detail where your spill kits are located, who is trained to use them and how to maintain your bunding.
