Life-Cycle Costing (LCC) / Whole-Life Cost

Life-cycle costing (LCC), also called whole-life costing or total cost of ownership (TCO), is an evaluation method where the contracting authority calculates and compares the full economic cost of competing offers over a defined period, rather than comparing only the purchase price. Cost elements typically include: capital cost, installation and commissioning, energy consumption, maintenance and servicing, consumables, end-of-life disposal or recycling, and sometimes externalized costs such as carbon emissions.

EU Directive 2014/24/EU explicitly permits LCC as an award criterion, and the EU taxonomy has driven significant adoption of environmental LCC — particularly carbon pricing — in public procurement for vehicles, equipment, and buildings. The EU has published a voluntary common methodology for environmental LCC to promote consistency.

For vendors, LCC evaluation favours products and services with lower operating costs even if capital cost is higher. This opens commercial opportunity for vendors with more energy-efficient technology, longer service life products, or lower maintenance requirements. The challenge is that LCC modelling requires vendors to provide input data — expected energy consumption, maintenance cycles, failure rates — that can be verified and challenged by evaluators. Conservative, evidence-based LCC submissions hold up better to scrutiny than optimistic projections.
