Yes. L123 Ltd specialises in managing electrical compliance and testing programmes across large, multi-site property portfolios.

We regularly support clients with estates ranging from tens to thousands of properties, including public-sector bodies, housing providers, commercial organisations; Universities and Retailers. Our delivery model is specifically designed to manage scale, complexity and geographic spread without compromising compliance, quality or service continuity.

Large portfolios are managed through a structured approach that includes:

Dedicated contract management and clear points of contact

Planned inspection and testing programmes aligned to statutory cycles

Regional engineer deployment to reduce travel time and disruption

Advance access planning for occupied or operational premises

Clear reporting and certification suitable for audits and governance

Our systems and processes allow us to track progress, manage exceptions and prioritise risk across an estate, ensuring that high-risk items are addressed promptly and compliance remains visible and controlled at all times.

Where required, we also support clients with phased mobilisation, data validation, backlog clearance and ongoing programme management to bring portfolios into compliance and keep them there.

This approach enables L123 Ltd to deliver reliable, regulation-led services at scale, while giving clients confidence that their estate is being managed safely, efficiently and transparently.
