Why UK compliance matters

UK law limits at-home teeth whitening to 0.1% hydrogen peroxide — anything above that can only be supplied by a registered dental professional, and even they can't exceed 6%. Yet many whitening products sold online contain far more.

A typical "35% carbamide peroxide" gel, sold freely on some websites releases around 12% hydrogen peroxide once used. That's over 100 times the legal consumer limit, and double what a dentist is allowed to use. In late 2025, a BBC investigation found illegal kits being sold with peroxide levels as high as 53%.

Most shoppers have no idea the 0.1% limit exists, so a "35%" product can sound powerful rather than illegal. That's the gap we close: every product we list meets the UK limit, so you don't need to decode the label yourself.

Above that, up to 6%, they can only be supplied through a dentist or GDC-registered professional who oversees the first use. Read more about the UK peroxide limit. →
