What We Do

Most clients who come to us are managing too many moving parts. Multiple contractors, fragmented accountability, and no single team with a clear view of the full picture.

ASG was built to solve that. Every division sits in-house: Mechanical, Lighting, Service and Maintenance, Wait and Load, and Soft Strip Out.

One contract, one team, one point of contact.

When something needs resolving, you are not chasing three contractors. You are calling us.

Our involvement does not stop at practical completion either. We support clients through the full lifecycle of their systems, from initial brief through installation, commissioning, and long-term planned maintenance.

That is what working with a principal contractor actually looks like.

Built on Trust

ASG has been delivering M&E projects since 2001. The majority of our work comes from clients who have worked with us before, or from referrals by those who have.

We hold preferred supplier status with some of the UK’s largest facilities management firms. We have delivered projects for Circle Health Group, British Airways, and Fidelity International. We do not win that work on price. We win it because our clients know what they are getting before the project starts.

If you are evaluating contractors, that is the most useful thing we can tell you. Ask us for references.
