Lighting & Energy

Lighting design, supply, installation and commissioning across commercial estates and fit-out programmes. Brand-agnostic specification, chosen on building performance. We deliver energy-led retrofits on existing buildings and full scheme design for new and refurbished spaces.

What the
service covers

Two situations bring clients to us. The first is an ageing estate: lighting specced for a different era, fluorescent kit being phased out of production, rising bills and maintenance that keeps climbing, often with no proper audit ever done. The second is a new or refurbished space that needs its lighting designed properly from the start, scheme, levels and controls, not just fittings picked off a price list.

ASG’s lighting division manages the full project: survey, design, supply, installation, commissioning, and ongoing maintenance. On fit-out and new-build programmes the work starts earlier: we design the scheme from the architecture and the brief, prove it to lux level before anything is ordered, and deliver it through to commissioning. Emergency lighting testing and certification are included, as are lighting controls and the maintenance of those systems. Work runs from focused upgrades on individual offices at a few thousand pounds to full estate replacements across multiple sites. We work with all major manufacturers with no commercial tie to any single brand, so the specification is based entirely on what the building needs.

How we deliver it

Scheme design
We take a shell, Cat A or refurbished space and design the lighting scheme from the architecture and the brief. Every scheme is modelled to lux level in DIALux before anything is ordered, with design-grade fittings specified on the look and the levels the space needs, not on supplier margin.
Energy survey and specification
Free energy survey included as standard. We assess current consumption, identify where energy is being lost, and produce a full specification with costs, savings and payback before any procurement decision. Reporting covers ESOS, SECR and TM44 where applicable.
Brand-agnostic specification
We work with the full range of leading manufacturers with no commercial tie to any single brand. The system we specify, including lighting controls and emergency systems, is based entirely on what the building needs.
ROI & aftercare
From first fix to commissioning, we manage installations planned around live operations, and hand over a full O&M and compliance pack before we leave site. Every installation carries a 12-month workmanship warranty and 24-month materials cover, with post-install check-ins to confirm the system is performing to specification.
