TPO phase-out: Key changes and what they mean for your insurance

Why TPO is being phased out
The nail industry is facing major changes as TPO (Trimethylbenzoyl Diphenylphosphine Oxide), a key ingredient in gel systems, has been reclassified due to safety concerns. Regulators are removing it from cosmetic use, with stricter rules already in place in the EU and Northern Ireland.

Key dates for Great Britain

• August 2026: TPO-containing products can no longer be manufactured or newly sold. From this point, nail technicians will no longer be able to purchase new TPO products but may continue to use existing stock, provided it remains legally compliant and is used in line with manufacturer instructions.
• February 2027: TPO-containing products can no longer be supplied or sold. While there is no explicit ban on using existing stock, technicians must ensure products remain legally permitted, are used in accordance with current regulations, and align with recognised professional guidance.

Different rules across borders
In the EU and Northern Ireland, TPO-containing products are already prohibited, including existing stock. Nail technicians working across these regions must comply with these stricter requirements.

Insurance requirements and risks
For insurance cover to remain valid, practitioners must ensure:

• All products used are legally permitted at the time of treatment
• Products are used in line with manufacturer instructions
• Practitioners remain aware of regulatory changes and key deadlines
• Products are not used in breach of UK or EU cosmetic regulations

How to protect your business

• Transition early to TPO-free systems
• Confirm compliance with suppliers
• Keep clear records (Safety Data Sheets, ingredient lists, supplier confirmations)
• Stay up to date with regulatory and industry guidance

The bottom line
TPO is being phased out, and the direction is clear. Taking early action will help protect your clients, maintain compliance, and ensure your insurance cover remains in place.
