How to Dispose of Used Cooking Oil: A Legal Guide for UK Businesses

Why Proper Disposal Matters for Your Business

Used cooking oil is classified as a controlled waste under the Environmental Protection Act 1990. That means every food business in the UK — restaurants, takeaways, hotels, schools, hospitals, food manufacturers — has a legal duty of care to ensure it is handled and disposed of correctly.

Pouring used oil down a drain is not just bad practice — it's a criminal offence. Blockages caused by fats, oils and grease (FOG) cost UK water companies over £100 million per year to clear, and local authorities actively prosecute businesses found responsible.

The consequences can include:

• Fines of up to £20,000 per incident
• Criminal prosecution of the business owner or manager
• Reputational damage and food hygiene rating implications
• Enforcement action from the Environment Agency or local council

Getting your disposal right protects your business, your licence, and the environment.

Your Duty of Care: What the Law Requires

Under the Waste (England and Wales) Regulations 2011 and the Environmental Protection Act 1990, any business that produces, stores, handles or disposes of waste — including used cooking oil — must:

1. Use only a licensed waste carrier — You must check your collector holds a valid Environment Agency waste carrier licence before handing over any waste. You can verify licences on the Environment Agency public register.
2. Obtain a Waste Transfer Note — Every collection must be accompanied by a completed Waste Transfer Note (WTN) describing the waste, its quantity, and where it's going. You must keep copies for a minimum of two years.
3. Never mix waste streams — Used cooking oil must be stored separately from other waste and in a secure, sealed container to prevent contamination or spillage.
4. Store waste safely — Containers must be fit for purpose, clearly labelled, and positioned to prevent leaks reaching drains or watercourses.

Bio UK Fuels holds Environment Agency waste carrier licence CBDU199369 and environmental permit EPR/GP3623PJ. We issue fully compliant Waste Transfer Notes with every collection.

How Commercial Used Cooking Oil Collection Works

Professional used cooking oil collection is straightforward — and with Bio UK Fuels, it's completely free of charge.

Here's what to expect:

Step 1 — Initial contact: Call us on 01709 373248 or complete our online enquiry form. We'll discuss your volumes, collection frequency, and any site access considerations.

Step 2 — Container placement: We supply sealed, purpose-built collection containers at no cost. These are food-grade IBC tanks or drum containers depending on your volume. They're clearly labelled and meet Environment Agency storage requirements.

Step 3 — Regular collection: Our licensed drivers collect on an agreed schedule — weekly, fortnightly or monthly depending on your output. We're flexible around your operation.

Step 4 — Waste Transfer Note: A completed WTN is provided at every collection. Keep this on file — it's your legal proof of compliant disposal.

Step 5 — Recycling: Your used oil is transported to our licensed facility and processed into biodiesel for use in commercial vehicles and industrial machinery, keeping it completely out of the waste stream.

There are no hidden fees. Our revenue comes from the recycled product, not from your business.

What Happens to Your Used Cooking Oil?

Once collected, used cooking oil is processed into biodiesel through a chemical conversion process called transesterification. This produces a clean-burning fuel that can power commercial vehicles and industrial plant — reducing reliance on fossil fuels and cutting carbon emissions.

Biodiesel produced from used cooking oil carries a double counting benefit under the Renewable Transport Fuel Obligation (RTFO), making it one of the most carbon-efficient fuel sources available. This is why reputable collectors like Bio UK Fuels can offer free collection — the recycled product has genuine commercial value.

The by-product of biodiesel production, glycerine, is refined and used in pharmaceuticals, cosmetics and food production. Nothing from your used cooking oil goes to waste.

How Much Used Oil Does Your Business Need to Produce?

We collect from businesses of all sizes. As a rough guide:

• Small takeaway or café: 25–100 litres per month
• Medium restaurant or pub kitchen: 100–300 litres per month
• Large restaurant, hotel or canteen: 300–1,000 litres per month
• Food manufacturer or processor: 1,000+ litres per month

If you're unsure of your volumes, we can advise based on your fryer capacity and cooking frequency. There's no minimum volume requirement to use our service — if you're producing used cooking oil as a business, we want to hear from you.
