ALPHA Flying Helmet – Sales, Maintenance and Repair

Because your head is your key asset!

As the United Kingdoms only officially authorised Gentex Europe/HISL ALPHA helmet service, maintenance and repair organisation, we are uniquely positioned to provide you with end to end ALPHA helmet support.

We are passionate about aviator safety and we provide support to users of Pilot Flight Equipment world-wide.

In 2013 we started providing maintenance training and technical support on behalf of Helmet Integrated Systems Limited (HISL) to flight helmet users around the world. Utilising our collective military flight helmet maintenance and instructional skills we provide robust maintenance practices and an excellent customer experience. 

HISL was acquired by Gentex USA, and ALPHA helmets are now part of the Gentex Europe helmet range.  

If you are looking to purchase ALPHA helmets, or just want to replace your headset with something a little more robust, we can help you to match the correct flight helmet to your exacting requirements.  

We can help you select the correct model and equipment level for your new flight helmet, assisting you to choose from a range of optional components as well as sizing and fitting the helmet.

Utilise our knowledge of ALPHA helmets to help you select and purchase your valuable asset and then have your ALPHA flight helmet professionally maintained by the UK’s only officially authorised Gentex ALPHA helmet service, maintenance and repair organisation
