Mechanical, Electrical & HVAC

Full mechanical design, supply, installation, and commissioning for commercial and industrial buildings. HVAC, heat pumps, chillers, AHUs, and plant replacement. One contractor, from survey to sign-off.

What the
service covers

Many commercial estates are running mechanical plant installed for a different era of energy market and regulatory regime. Ageing chillers, legacy refrigerants facing phase-out, and AHUs sized for floorplates that no longer exist. The operational and compliance cost of carrying on is often higher than the cost of replacement. The replacement works themselves are where projects tend to go wrong.

ASG manages from first fix to sign-off, planned around your operations. Engineers deliver the core works, supported by vetted service partners where specialist trades are required. Quality, scheduling, and site conduct stay under ASG control throughout.

How we deliver it

Design & specification
We survey the site, assess existing plant, and produce a full specification before any works are agreed. You get a clear picture of scope, cost, and programme before committing to anything.
Installation & commissioning
Core works are delivered by ASG engineers, with specialist trades brought in under ASG management where required. Quality, scheduling, and site conduct stay under our control throughout.
Principal contractor delivery
We act as principal contractor across the full project lifecycle: survey, design, install, commission, and ongoing service. One team, one point of contact, one contractor from first site visit through to long-term maintenance.
Compliance & documentation
Building regulations sign-off, F-Gas records, commissioning certification, and O&M documentation are handled as part of delivery. Nothing incomplete lands on your desk at handover.
