The TPO Ban Has Landed, What Every UK Nail Technician Needs to Know
If you work with gel polish, builder gel, or BIAB, the TPO ban is something happening right now that affects your kit directly. TPO — the ingredient that lets gel cure hard and glossy under a UV or LED lamp — is being phased out of UK nail products, and the first deadline has already passed this month.

What Is TPO, and Why Is It Being Banned?
Trimethylbenzoyl diphenylphosphine oxide (TPO) is a photoinitiator — it's what makes liquid gel set into a solid, shiny layer under lamp light. It's been reclassified as a CMR 1B substance (carcinogenic, mutagenic, or toxic to reproduction), which triggered a ban under UK cosmetics regulation, following the EU's lead. Some in the industry argue the classification is overly cautious, pointing out it's based on high-concentration oral exposure in animal testing rather than the low-concentration topical use seen in a salon setting. Regardless of the debate, the ban is now in force.

The Key Dates
- 1 September 2025 — TPO banned in EU cosmetic products
- 15 August 2026 — UK manufacturers can no longer supply new TPO-containing products to retailers
- 14 February 2027 — Distributors and technicians can no longer purchase TPO-containing products; existing stock can still be used on clients after this date
In other words: we're now past the manufacturer cut-off. Reformulated, TPO-free products are already reaching salons, and technicians have until February 2027 to use up any stock that still contains it.

What The TPO Ban Means for Your Kit
Gel polish is the product most directly affected, and many brands are already reformulating builder gel and BIAB ranges too. A few practical steps:
- Check your ingredient lists for Trimethylbenzoyl diphenylphosphine oxide (TPO) on anything you're currently using or about to restock
- Ask your suppliers for written confirmation of whether a product has been reformulated — several already operate without TPO or well below the old guideline concentration
- Don't panic-buy or panic-dump stock — existing TPO products remain legal to use on clients until February 2027, so there's a genuine transition window
- Check compatibility if you do switch brands, since reformulated gels can cure slightly differently under the same lamp

Why This Matters Beyond Compliance
This is exactly the kind of update that separates technicians who are simply "doing nails" from those running a genuinely professional business. Clients are increasingly asking questions about what's in the products used on them, and being able to answer confidently — because you actually understand your ingredients rather than just following a routine — builds real trust and repeat bookings.
It's also a good reminder of why training from an accredited source matters: courses built around current UK standards keep you ahead of changes like this, rather than finding out about them after the fact from a supplier email.
