How Symphony Delivers ROI Without Disrupting Your Operations

No rip-and-replace. No lengthy procurement process. Most buildings are up and running within weeks.

We Audit Your Building

We assess your current energy performance, identify where energy is being wasted, and model the savings you can expect. You get a clear projection before committing to anything.

We Install and Optimise

Our technology integrates with your existing systems. We take over the ongoing management and optimisation without your facilities team needing to change how they work.

You Capture the Savings

Energy costs drop. We share in the savings under whichever pricing model suits your balance sheet. You retain full visibility through our cloud reporting platform.

Option 1

Zero Capex Shared Savings

No upfront cost. No capital expenditure. We fund and install everything.

75% to Symphony / 25% to you for the first four years, then 50/50 from year five onwards. Once the system is paid down, savings continue and the split improves.

Built-in exit option. If your circumstances change, you're not locked in indefinitely.

Option 2

Engagement Fee Higher Savings Share

A one-time engagement fee of €1 per square foot. In return, the savings split is 50/50 from day one, across an eight-year term.

Over the lifetime of the contract, this model generates significantly higher return. The payback period on the engagement fee is typically less than 2-years.

Built-in exit option. The same exit flexibility applies.
