Charging-as-a-Service finance: how UK operators fund CaaS rollouts
Charging-as-a-Service turns a capital purchase into a monthly fee for the site owner. Someone still has to buy the kit. This guide covers how operators and installers fund CaaS portfolios in the UK, and what funders need to see before they will back the contracts.
Written by Tom, Power and Energy Finance Specialist · Updated October 2026
The short version
- In a CaaS model the operator owns the chargers and the site pays a fixed or usage-linked monthly fee.
- The operator funds the hardware and installation, so the facility term should match the customer contract term.
- Funders look hardest at the strength of the customers paying the fees, not just the operator.
- Maintenance, software and uptime obligations sit with the operator and need costing into the fee from day one.
- Portfolios usually start with asset finance per site, then move to a revolving or project-style facility as contracts stack up.
How Charging-as-a-Service works
Under CaaS the site owner, often a fleet operator, landlord or employer, does not buy the chargers. An operator installs, owns and maintains them, and charges the site a monthly fee over a fixed term. The fee normally bundles hardware, installation, software, maintenance and a service level for uptime.
For the site owner it keeps capital free and moves operating risk to a specialist. For the operator it builds recurring revenue, but it also means funding every installation upfront and carrying that cost until the fees pay it back.
| Item | Site owner | Operator |
|---|---|---|
| Upfront hardware and installation | No | Yes, funded |
| Monthly service fee | Pays | Receives |
| Maintenance and repairs | No | Yes |
| Back office software and payments | No | Yes |
| Uptime commitment | Benefits | Guarantees |
| Ownership at end of term | Per contract | Usually retains or sells |
Match the facility to the customer contract
The single most important structuring point is term matching. If a customer signs a five year CaaS agreement and the operator funds the kit over three years, the operator runs negative cash flow for the first three years. If the funding runs longer than the contract, the operator carries renewal risk on debt it still owes.
We aim to line up the facility term, repayment profile and any balloon with the contracted fee stream, so each site broadly pays for itself from the first month.

- Facility term no longer than the customer contract term.
- Repayments sized below the contracted monthly fee, leaving margin for maintenance.
- A balloon only where residual value or a renewal is realistic.
- Early termination terms in the customer contract that cover the outstanding balance.
What funders look at
A CaaS facility is partly a bet on the operator and partly a bet on its customers. Funders want to know who is paying the monthly fees and how secure those contracts are. A portfolio of fees from established fleet operators and public bodies reads very differently from short, cancellable agreements with small sites.
They will also look at the hardware: proven manufacturers, warranty terms and a credible maintenance arrangement all matter, because a charger that is down does not earn its fee.
- Signed customer contracts, term and termination clauses.
- Credit strength of the paying customers.
- Operator trading history and management experience.
- Hardware specification, warranty and maintenance plan.
- Site access rights, for example a lease or licence for the bays.
From one site to a portfolio
Most operators start by funding each site on its own hire purchase or lease agreement. That is quick and straightforward, but becomes heavy to administer at scale. Once there is a track record and a pipeline of contracts, a revolving facility or a project-style structure with drawdowns per site can cut the paperwork and improve pricing.
The right point to move depends on contract volume and quality rather than a fixed number. We usually look at it once an operator has several sites live and a visible pipeline behind them.

FAQs
Common questions
The questions that come up most often on this subject.
What is Charging-as-a-Service?
A model where an operator installs, owns and maintains EV chargers at a site, and the site owner pays a monthly fee instead of buying the equipment.
Can a CaaS operator fund chargers with asset finance?
Yes. Hardware and installation can normally be funded on hire purchase or lease, ideally over a term that matches the customer contract.
What do funders need to see for a CaaS facility?
Signed customer contracts, the credit strength of those customers, the operator's track record, the hardware and maintenance plan, and the right to use the site.
Is CaaS better than buying chargers outright?
It depends on the site. CaaS keeps capital free and moves maintenance risk to the operator, but the total paid over the term is usually higher than owning. Buying on asset finance is often cheaper for sites that can manage the kit themselves.
