Knowing who you're dealing with is important so always use a company that has some form of registration.   Any reputable systems installer should be either SSAIB or NSI registered. If they aren't then give them a miss.


2017 saw us being awarded and joining the DHF.
The DHF governing body within the automatic door, barrier and gate industry & setting the standard for safe working practices, working closely with the HSE. Their hands-on way of operating with approved companies like us means that customers are assured of the very best in safe working systems. Engineers and designs staff have to pass stringent exam and tests to qualify to carry the DHF approved ID.

2015 saw us being awarded SafeContractor approval in all areas of our wide range of services. This is testament to the hard works of the entire ASG team as was not easily achieved with such a diverse range of services, but we're very proud to be able to demonstrate to clients our safe working practices..



We've held SSAIB registration for nearly 20 years now, and are proud of our reputation. Each year the inspectors visit and review our installations, our maintenance procedures and our paperwork to ensure we're meeting there standards. Each year we pass with flying colours.

This gives you the comfort and assurance that an independent UKAS accredited inspectorate is checking through our business to ensure we're doing our job well.



The Automatic Door Installation Association (The ADIA) is a governing body aimed at installers of automatic entrance and a organisation that places a large importance on training of members engineers and sales staff so again you can e assured of the right solution and knowledgeable engineering staff.

ASG staff hold CSCS certification, which means staff have had to demonstrate a good level of understanding and skill in Health & Safety and working practices on business and construction sites

What Client say's

“the depth of what I call real world knowledge amid experience of what works and what doesn't is the main reason we've been using ASG for the last 14 years. There ability to think out side of the box and not just selling me something because its what I thought I wanted is unusually refreshing”
