Unrivalled security

Every Comp Door® comes equipped with the highly trusted Avocet ABS anti-snap diamond grade cylinder setting the standard for safety and peace of mind.

The Avocet ABS includes a multi-latch deadbolt that automatically fires into action as soon as the door is shut, there’s no need to lift the handle. Each and every lock is designed, developed and rigorously tested in the UK, providing a uniquely coded lock to your home that provides unparalleled security.

Here’s why the Avocet ABD is a game-changer:

The multi-latch deadbolt automatically fires into action as soon as the door is shut: no need to lift the handle.
Leaving a key in the inside lock won’t affect its performance, adding convenience to its reliability.
Each lock is uniquely coded, ensuring only you, the homeowner, have access to the code.
Designed, developed, and rigorously tested in the UK, these locks meet the highest security standards, including TS007 3-star, British Kitemark, Sold Secure, and Secured by Design certifications.

Plus, Avocet offers £2,000 compensation if a break-in occurs due to lock snapping – proof of their confidence in their product. For extra convenience, multiple locks can be configured to work with a single key.

Modern Technology

Comp Door has now introduced KUBU, an Intelligent Alerting System that monitors the security status of your door in real time – sending a notification to your Smart device if there is anything to worry about.

By seamlessly integrating with the locking hardware in your Comp Door, the KUBU sensor can tell if your door has been: opened, closed, deadlocked or even if it is under attack.

Unlike most other systems, KUBU can alert you to threats before an intruder can breach your home, giving you an early warning and helping to keep your home & family safe. KUBU integrates easily with other smart-home devices like speakers, heating, and lighting – making your entire home smarter and more secure.

If that’s not enough, KUBU also ensures peace of mind by notifying you if you’ve forgotten to lock your door when you leave, can send scheduled alerts – like at bedtime – about your door’s status, and even allows you to share updates with loved ones.

And best of all, KUBU is included for FREE with every door purchased from Comp Door. Visit Get KUBU to find out more!

Choice and Styling of Comp Door®

With Comp Door® ®, you’ll find a wide range of composite door styles and colours to suit your home and taste.

Whether you prefer a classic look from the Traditional range or a modern design like Abercorn, luxury and style come as standard. You can even choose to have your door styled as French doors or Stable doors if you are looking to make a statement!

Want something unique? Mix and match with matching side panels and a variety of glazing patterns to create a door that truly stands out. And don’t worry if you already have existing features.
