Own your chargers or use charging-as-a-service? A neutral comparison
Buying outright is cheapest long-term and gives control; charging-as-a-service cuts upfront cost and risk. Here's the honest trade-off.

Two broad ways exist to fund depot charging, and each has a supplier who prefers it — which is exactly why a neutral comparison is worth having.
Ownership: cheapest long-term, most control
Buying and owning the chargers and civils outright means the lowest cost over the life of the equipment and full control of how it’s run. The price is the biggest upfront outlay and responsibility for maintenance. If you have the capital and want the running savings to flow straight to your bottom line, ownership usually wins on total cost.
Charging-as-a-service: less upfront, less risk
Under charging-as-a-service (CaaS), a provider funds, installs and maintains the infrastructure and you pay over time — often per unit of energy or a regular fee. You free up cash and hand the technical risk to someone else, but you pay more overall and depend on that provider. It suits organisations that would rather not tie up capital or carry the in-house capability.
Leasing sits in between
Leasing spreads the capital cost while you keep operational control — a middle path when outright purchase is a stretch but you still want to own the running benefits.
How to decide
There’s no universally right answer. Weigh your appetite for upfront investment against ongoing cost, and how much you want to run in-house. Crucially, run the numbers with grants applied before defaulting to a service model — funding often tips the balance toward owning. Whatever you choose, protect yourself with a tender and contract terms built on open standards.
