How to Choose the Right Spill Kit — UK Buyer's Guide

Last updated: April 2026

Selecting the correct spill kit is not a matter of buying the cheapest option and hoping for the best. In the UK, the Health and Safety Executive (HSE), Environment Agency (EA), and your COSHH risk assessment all have a bearing on what constitutes an appropriate spill response capability for your workplace. Get it wrong and you face inadequate cleanup, environmental contamination, regulatory fines, and potential injury to your staff.

This guide takes you through the three main types of spill kit available in the UK market, explains absorbency ratings and litre capacity requirements, covers how to conduct a proper workplace assessment, and outlines the legal requirements you need to satisfy. Whether you operate a small garage, a manufacturing facility, or a chemical distribution depot, this guide will help you choose with confidence.

The Three Types of Spill Kit — Oil, Chemical, and General Purpose

Not all spill kits are created equal. The absorbent materials inside each type are engineered for specific liquids, and using the wrong type can actually make a spill worse or create additional hazards.

Oil-Only Spill Kits

Oil-only spill kits use white polypropylene sorbent materials that are hydrophobic — they repel water while absorbing hydrocarbons. This makes them ideal for:

• Engine oil, lubricating oils, and hydraulic fluid spills
• Diesel, petrol, kerosene, and other fuel spills
• Transformer oil and mineral oil spills
• Any oil-on-water situation — the sorbents float and absorb only the oil

The hydrophobic property is critical for outdoor spills near drains, puddles, or water features, where you need to capture oil without picking up large volumes of water that would rapidly saturate your absorbents. Oil-only kits are the correct choice for vehicle workshops, fuel storage areas, plant rooms, and any location where hydrocarbon spills are the primary risk.

Chemical Spill Kits

Chemical spill kits use yellow or orange sorbent materials that are universal absorbers — they will absorb both aqueous and non-aqueous liquids, acids, alkalis, solvents, and a wide range of industrial chemicals. They are the appropriate choice for:

• Acids and alkalis (battery acid, caustic soda, hydrochloric acid)
• Solvents, acetone, alcohols, and glycols
• Unknown chemical spills — the safest default where substance identity is uncertain
• Mixed chemical environments such as laboratories, chemical manufacturing, and water treatment

Important: chemical sorbents absorb both water and chemicals, so they are not appropriate for outdoor use where rain contamination would waste absorbency capacity. Always use chemical kits inside, or in sheltered outdoor areas. Check SDS Section 6 (accidental release measures) for any substance-specific guidance on absorbents.

General Purpose Spill Kits

General purpose (GP) kits use grey sorbent pads and rolls that will absorb almost any liquid — oil, water, chemicals, coolants, and beverages. They are grey because the sorbent materials are typically recycled fibres rather than virgin polypropylene. GP kits are appropriate for:

• Mixed-use environments where multiple liquid types may be spilled
• Indoor areas where the primary liquids are coolants, water-based solutions, or general workshop fluids
• Welfare facilities, kitchens, and food production areas
• Low-risk environments where a cost-effective multi-purpose option is needed

The downside of GP kits: because they absorb water, they are inefficient for oil-on-water situations and can become saturated with rainwater if placed outdoors.

Understanding Absorbency Ratings and Litre Capacity

Spill kits are rated by the total volume of liquid they can absorb, expressed in litres. This is the most important specification when sizing a kit for your workplace. The capacity rating tells you the maximum volume of liquid the kit's contents can absorb before they are fully saturated and must be disposed of.

Individual sorbent pads typically absorb 1–2 litres each. Sorbent rolls absorb 30–50 litres. Socks and booms absorb 10–20 litres per metre. A well-composed 100-litre spill kit will typically contain approximately 20–30 pads, 1–2 rolls, 4–6 socks, and ancillary items including disposal bags, gloves, goggles, and ties.

Workplace Assessment — Choosing the Right Kit for Your Site

Before purchasing, conduct a structured workplace assessment:

1. Identify all liquid hazards

Walk every area where liquids are used, stored, or transferred. List each substance, its volume, and its hazard classification from the SDS. This forms the basis of your COSHH risk assessment and directly informs spill kit selection.

2. Identify spill risk points

Concentrate on areas of highest risk: decanting stations, forklift routes near chemical storage, loading bays, drum storage, process pipework, and pumping stations. A spill kit placed 50 metres from a risk point is essentially useless in the first critical minutes of a spill.

3. Assess drainage vulnerability

Are there floor drains, gullies, or channels near the risk areas? If so, your spill kit must be supplemented with drain covers or plugs — a critical item often overlooked. A fast-moving spill can reach a drain within seconds.

4. Consider access and training

Spill kits are only effective if staff can reach them, identify them, and know how to use them. Position kits at eye height, clearly signed, near the hazard but not so close that a spill would block access. Ensure all relevant staff have received basic spill response training.

5. Review quantities regularly

A spill kit that has been partially used and not restocked offers false assurance. Implement a monthly inspection regime and restock kits immediately after any use.

Maintenance and Inspection of Spill Kits

Under COSHH Regulation 9 (maintenance, examination, and testing of control measures), spill response equipment must be maintained in efficient working order and good repair. For spill kits, this means:

• Monthly visual inspection: Check the kit is present, fully stocked, seal is intact, and absorbents are dry and uncontaminated
• Annual formal inspection: Check all components against the original kit specification; check absorbents for degradation, especially if stored in damp conditions
• Post-use restock: Replace any used components immediately; never leave a partially used kit as the only response resource
• Record keeping: Log all inspections with date, inspector name, findings, and actions taken
• Disposal: Used sorbents contaminated with hazardous substances must be disposed of as hazardous waste under the Hazardous Waste Regulations 2005

Legal Requirements for Spill Kits in the UK

There is no single regulation that specifies "you must have a spill kit." Instead, the requirement flows from several overlapping pieces of legislation:

• COSHH Regulations 2002, Regulation 7(3)(c): Requires adequate emergency procedures and equipment for dealing with accidents, incidents, and emergencies involving hazardous substances
• Management of Health and Safety at Work Regulations 1999: Requires employers to have appropriate procedures for serious and imminent danger
• Control of Pollution (Oil Storage) (England) Regulations 2001: For oil storage above 200 litres, requires equipment to deal with oil spills — a suitable oil-only spill kit satisfies this requirement
• Environment Agency PPG 22 (Incident response — dealing with spills): Provides guidance that sites near drains or watercourses should have spill response materials immediately available
• Water Resources Act 1991: Makes it a criminal offence to cause or knowingly permit polluting matter to enter controlled waters — an adequate spill kit is part of your defence
