Device as a Service turns hardware from a one-off purchase into a managed, all-in subscription. Instead of buying phones and managing them yourself, you pay a monthly fee per device and the provider handles supply, configuration, security, support and recycling. This guide explains how DaaS works, how it differs from leasing, and when it makes sense for UK businesses.
DaaS is one of several funding routes; see how it compares in our guide to how to finance business phones.
What does Device as a Service mean?
DaaS is a subscription model where the device and everything around it is delivered as a managed service. A single per-device fee typically covers:
- Hardware: the phone, tablet or laptop itself.
- Provisioning: devices arrive pre-configured with your apps and security.
- Management: mobile device management, updates and policy enforcement.
- Support: repairs, swap-outs and a helpdesk for the device life.
- End of life: secure wiping, recycling and refresh to new devices.
The result is a fleet that stays current, secure and supported without your team managing each step.
An example of Device as a Service
Imagine a 40-person field team. With DaaS, you agree a per-device monthly fee, and the provider ships 40 rugged or standard phones already loaded with your email, apps and security profile. If one breaks, a replacement is dispatched and the old unit wiped. At 36 months, the whole fleet is refreshed to new devices and the old ones are recycled, all on the same predictable bill.
For field-heavy teams, DaaS often pairs with rugged business phones so durability and management are handled together.
What is the difference between DaaS and leasing?
This is the most common DaaS question. Both spread cost, but they cover very different scopes.
| Feature | Leasing | Device as a Service |
|---|---|---|
| Device finance | Yes | Yes |
| Pre-configuration | No | Yes |
| Security & management | No | Yes |
| Support & repairs | Sometimes | Yes |
| End-of-life recycling | Sometimes | Yes |
In short, leasing finances the hardware; DaaS finances and manages the whole device lifecycle. If you only want to spread cost, see business mobile leasing; if you want it managed end to end, DaaS is the fit.
Benefits of DaaS for business
DaaS appeals most to businesses that want to reduce IT workload and keep costs predictable.
- Predictable cost: one per-device fee, easy to budget and scale.
- Less admin: provisioning, support and recycling are outsourced.
- Always current and secure: devices are kept patched and managed.
- Sustainability: structured refresh and recycling supports ESG reporting.
- Scales with headcount: add or remove devices as the team changes.
When DaaS may not be the right fit
DaaS is not always the cheapest route, so weigh it against your situation.
- If you keep devices for many years, buying outright costs less overall.
- Very small teams may not need the management layer.
- You are paying for a service, so the total cost is higher than bare leasing.
For a handful of devices, a simple contract or refurbished purchase may be more economical. For larger or field-based fleets, the management savings usually justify the fee.
DaaS and managed mobile services
DaaS sits naturally within a broader managed mobile service, where airtime, devices and support are delivered together. For organisations running large fleets, combining DaaS with enterprise mobile fleet management gives full visibility and control over every device on one contract.

Frequently Asked Questions
A typical example is a business paying a fixed monthly fee per phone, with the provider shipping pre-configured devices, managing security and support, and refreshing and recycling the fleet at the end of the term. The business never buys the hardware; it consumes the device as a managed service.
It means consuming hardware as a subscription rather than buying it. A single per-device monthly fee covers the device, configuration, security, management, support and end-of-life recycling, so the fleet is fully managed throughout its life.
Leasing finances the device only; you still configure, secure, support and dispose of it. DaaS finances and manages the whole lifecycle, including provisioning, security, support and recycling. DaaS costs more than bare leasing but removes the management workload.
It depends on how much management you need. Very small teams that keep devices for years may find buying outright or a simple contract cheaper. DaaS becomes worthwhile when you want predictable costs and to outsource provisioning, security and support, which is common once a fleet grows.
Yes. Security management, updates, helpdesk support and device repairs or swaps are core parts of a DaaS contract, alongside the hardware and recycling. That managed layer is the main difference from a straightforward device lease.
