How to Buy Spill Control Equipment: A Practical UK Procurement Guide
Purchasing spill control equipment for your site is not as straightforward as it might appear. The wrong product — a spill kit with inappropriate absorbents, a bund with insufficient capacity, or a drain seal that does not fit your drainage system — can leave you legally exposed and practically unprotected when an incident occurs. This guide sets out the key considerations for UK site managers and procurement teams buying spill control products, whether for a single location or a multi-site estate.
Start with a Site Chemical Risk Assessment
Before purchasing a single piece of spill control equipment, you must understand what you are trying to contain. A COSHH assessment under the Control of Substances Hazardous to Health Regulations 2002 should identify every hazardous substance on site, the quantities stored, storage locations, and realistic worst-case spill scenarios. This assessment drives all subsequent procurement decisions, from absorbent type to bund capacity.
Do not guess. If your site stores oils, fuels, chemicals, and water-based substances, you will likely need multiple categories of spill control equipment — and they are not interchangeable.
Key Buying Criteria by Product Category
| Product | Critical Specification | Common Mistakes |
|---|---|---|
| Spill kits | Correct sorbent type (oil-only, universal, chemical) and correct litre capacity | Buying universal kits for chemical areas; undersizing capacity |
| Spill pallets | Bund capacity (must hold 110% of largest drum), chemical compatibility, UN approval where needed | Ignoring chemical resistance; buying low-cost pallets without UN certification |
| Absorbent pads and rolls | Absorbency rate, compatibility with liquid type, dimensions | Using oil-only pads on chemical spills; wrong absorbency rating |
| Drain seals | Drain size compatibility, deployment speed, chemical resistance | Wrong size; buying products untested with your specific liquids |
| IBC bunds | Capacity (110% IBC volume), forklift access, UV resistance for outdoor use | No forklift channels; inadequate outdoor UV stability |
UN Approval and COSHH Compliance
For secondary containment of hazardous chemicals, particularly in sites covered by the Control of Major Accident Hazards (COMAH) Regulations 2015 or the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR), you should specify UN-approved containment products. UN approval means the product has been independently tested and certified for use with hazardous materials. Look for the UN mark on spill pallets and storage cabinets when purchasing for chemical or flammable substance storage.
Capacity Calculation: Getting It Right
Under Environment Agency PPG 26 guidance, secondary containment must hold the greater of: 110% of the largest single container, or 25% of the total stored volume. This calculation must be performed for each storage area separately. Many sites underestimate their bund requirements — particularly when drum counts increase over time without corresponding containment upgrades. Perform this calculation before purchasing and build in a margin for operational growth.
Supplier Quality and Support
Not all spill control products are equal in quality. Look for suppliers who offer: detailed technical datasheets for every product; confirmation of chemical compatibility with your specific substances; clear guidance on capacity ratings and regulatory compliance; and responsive technical support. When in doubt, contact a specialist supplier directly with your chemical list and ask for written confirmation of suitability. This protects you if a product fails during an incident.

Budgeting for Compliance, Not Just Purchase Price
The cheapest product at point of purchase is rarely the most cost-effective choice. Factor in: replacement frequency for consumables like absorbent pads and spill kits; total cost of compliance including inspection, maintenance and staff training; and the cost of an inadequate product failing during an actual spill incident — which can run to tens of thousands of pounds in clean-up costs, Environment Agency fines, and reputational damage. Buy right the first time.
