It’s reassuring to know that our composite doors are arguably the most secure on the market, featuring insurance and Police approved locking systems. Britain’s most secure composite door has just got even better thanks to Ultion, a revolutionary locking system that when locked, stays locked!

When it detects attack, a hidden lock within the Ultion automatically engages, so that even when snapped twice nothing gets past it. Leaving a key on the inside of the lock won’t affect its performance either. Rigorously tested, nothing beats the Ultion, not even the finest 3 star locks, making it the UK’s best and most secure lock guaranteed.
