How to Read CBD Product Labels in the UK (Spot Quality, Avoid Scams)
Most CBD label scams aren't dramatic. They're subtle — a missing batch number here, vague language there, a "lab tested" claim with no actual report. After auditing hundreds of UK products, I've built a 7-point label-reading method that catches 95% of the dodgy ones in under 60 seconds. Here it is.
The 7-Point UK Label Checklist
Use this in order. If a product fails any of points 1-4, walk away. Points 5-7 are bonuses that distinguish good from great.
- 1
Total CBD content in mg — clearly stated on the front. Not "high strength", not "premium" — a real mg number.
- 2
CBD per serving — for gummies, mg per gummy. For oils, mg per drop or mg per ml. No serving info = walk away.
- 3
Batch/lot number — usually on the bottom or back. This must match the COA on the brand's website.
- 4
QR code or URL to lab report — leads directly to a PDF, not a vague "tested" page.
- 5
Type clearly stated — "Broad Spectrum", "Full Spectrum", or "Isolate". Not "spectrum" alone.
- 6
FSA Novel Food reference — e.g. RP349. Listed on the brand's website. Means the FSA has accepted their authorisation application.
- 7
Full ingredient list — no proprietary blends, no vague "natural flavourings". Real names of real things.

What a Real COA Should Show
The Certificate of Analysis (COA) is the document that turns marketing claims into verifiable fact. Here's what a real one should include:
- Issuing lab name + accreditation (ISO 17025 is the gold standard)
- Batch / lot number matching the product
- Date of analysis (should be within the last 12 months)
- Cannabinoid profile (CBD, CBG, CBN, CBC, THC content)
- Heavy metals test (lead, arsenic, cadmium, mercury — all should pass)
- Pesticides screen (multi-residue panel, must pass)
- Residual solvents (for CO2 or solvent-extracted products)
- Microbial contamination (yeast, mould, E. coli, salmonella)
If a brand publishes only their cannabinoid profile and nothing else, they're hiding their contamination panel — which means they probably failed it.
The 8 Red Flags I See Most Often
- "Premium" with no mg number. The word "premium" replaces actual data. Walk away.
- QR code that leads to a generic page. Should go straight to the matching PDF.
- Outdated COA (>12 months old). Hemp varies by harvest. Old reports = old product.
- Missing batch numbers. Can't verify the report matches what you're holding.
- No FSA reference. If it's an edible without FSA Novel Food status, it's technically illegal to sell.
- US-style claims. "Treats" or "cures" anything = breaking UK advertising rules.
- Total content in "ml" only. 30ml is the bottle volume, not the CBD content. Look for mg.
- Mystery suppliers. No company address, no contact info, no UK presence.
What a Good Label Looks Like
✅ Mg stated. ✅ Per-serving info. ✅ Batch reference. ✅ FSA number. ✅ COA link. ✅ Spectrum clear. This is what to look for.
Compare that to the typical dodgy label: "Premium CBD oil. High-strength formula. Lab tested. Hemp extract and natural flavourings." That's the absence of nearly every data point that matters.
Reading a CBD label is a 60-second skill that saves you from 90% of the bad products on the shelf. mg per dose, batch number, COA link, FSA reference, spectrum type, ingredient transparency. Anything missing? Anything vague? Put it down. Better-quality alternatives exist for the same or lower price. Read before you buy. Always.
