When schools should rent vs purchase water dispensers – a guide for facilities managers
When planning or upgrading drinking water provision, one of the first decisions schools face is whether to rent or purchase their water dispensers.
Both options can work well in the right circumstances. The key is understanding how each approach fits with your budget, site requirements and long-term plans.
In this guide, we outline when renting makes sense, when purchasing may be the better option, and what facilities managers should consider before making their decision.
When does it make sense for schools to rent water dispensers?
For many schools, renting water dispensers is a straightforward and flexible solution.
Renting is ideal for:
-
Schools upgrading multiple hydration points at once
-
Sites with limited capital budget
-
Facilities managers who want a fully managed solution
-
Schools without in-house maintenance capacity
The benefits of renting school water dispensers
Lower upfront costs
One of the main advantages of renting water dispensers is the reduced initial financial commitment. Instead of large upfront costs, they’re typically spread across manageable monthly or quarterly payments.
For schools working within fixed annual budgets, this can make it much easier to move forward with a project without delaying other planned improvements. It also allows facilities managers to implement a complete hydration solution across the site, rather than installing units gradually over time due to cost constraints.
This approach is particularly useful when upgrading outdated water dispensers or responding to new requirements, where time is of the essence. It can also give you access to more expensive units, such as advanced bottle filling stations, that may otherwise be beyond your budget.
That said, there are bottle filling stations available for all budgets. See our guide on bottle filling stations for schools for more information on your options.
Inclusive service and maintenance
Rental agreements often include ongoing servicing, filter replacements and repairs as part of the package. This removes the need to organise separate maintenance contracts or manage ad hoc repair costs.
For site teams, this can make a noticeable difference. Instead of tracking service schedules or troubleshooting faults internally, support is built in. Dispensers are kept safe, compliant and fully operational throughout the year with minimal effort on your part.
It also provides greater cost predictability. Rather than unexpected repair expenses, schools benefit from a more consistent, planned approach to maintenance.
Easier to scale across the site
For larger schools or multi-building sites, renting makes it more practical to install multiple dispensers at once.
Rather than prioritising certain areas and delaying others due to budget limitations, facilities managers can ensure corridors, dining areas, sports facilities and outdoor spaces are all properly covered.
This not only improves access to drinking water but also helps manage demand more effectively, reducing pressure on individual units and minimising queuing during peak times.
Flexibility over time
School environments rarely stay the same for too long. Pupil numbers can increase, buildings may be extended, and internal layouts often change.
Rental agreements provide a level of flexibility that supports these changes. Units can often be relocated, upgraded or added to as requirements evolve, without the constraints that come with fixed, owned assets.
This makes renting a practical option for schools planning development or adjusting how spaces are used. It allows your water provision to adapt alongside the school, rather than needing to be replaced or reworked later on.
When is it a better idea for schools to purchase water dispensers?
In some cases, purchasing water dispensers outright can offer schools better long-term value.
Purchasing is ideal for:
-
Schools with available budget
-
Sites with stable, long-term infrastructure
-
Facilities teams confident in managing maintenance
-
Smaller installations with fewer units
The benefits of owning school water dispensers
Lower lifetime cost (in the right scenario)
While purchasing water dispensers requires a larger initial investment, it can prove more cost-effective over the long term. Schools that use their dispensers consistently over many years may find that the upfront purchase cost is offset by the total cost of renting over the same period.
Owning units outright can also make long-term financial planning easier. With a clear upfront cost and manageable ongoing expenses such as maintenance and filter replacements, schools can better forecast total cost of ownership.
This approach works best in scenarios where dispensers are heavily used, well-maintained, and expected to remain in service for a decade or more.
Full control over assets
Purchasing water dispensers gives schools complete ownership of their equipment. This can be particularly appealing for facilities teams with established procurement or asset management processes.
Full ownership allows schools to manage the units according to their own schedules. You can decide when to upgrade, replace, or relocate units without needing to negotiate changes with a rental provider.
It also allows for easier integration into existing asset registers, which can simplify long-term planning and accounting for replacement cycles.
No ongoing rental commitments
Owning dispensers removes the need for ongoing rental agreements, which can simplify budgeting and reduce administrative overhead. Instead of managing recurring invoices or contract renewals, schools can focus on planned costs such as servicing and maintenance.
This can be particularly beneficial for schools looking to streamline supplier management or reduce the number of active service contracts across their estate.
However, it’s important to remember that owning equipment still requires a plan for servicing, maintenance, and potential repairs. While these costs are often lower and more predictable than rental payments, they must be accounted for to ensure dispensers remain safe and fully operational.
At Cactus Water Systems, we offer comprehensive, ongoing service and maintenance support for both purchased and rented units. Learn more about our sales and rental options.
Suitable for stable environments
Purchasing is most practical in schools where the layout, pupil numbers, and water usage patterns are unlikely to change significantly in the near future. If your facilities are stable, long-term ownership reduces dependency on outside agreements and provides a consistent hydration solution without the need for frequent reassessment.
Stable environments also benefit from the flexibility to customise installations, such as adjusting height or location of units to meet pupil needs, without being restricted by rental terms. Over time, this ensures that the investment continues to serve the school efficiently and effectively.
Key factors to consider before deciding between renting and purchasing water dispensers for schools
Whether renting or purchasing, the decision should be based on how the solution will perform day-to-day in your school environment.
Budget structure - Is it easier to manage operational expenditure (rental) or capital expenditure (purchase)? This often plays a major role in the decision.
Maintenance responsibilities - Who will handle servicing, repairs and filter changes? Renting typically includes this, while purchasing requires a separate plan led either by the school facilities team or a third-party provider.
In more complex environments, such as restricted plant rooms or confined installation areas, having the right support in place becomes even more important to ensure safe access and ongoing maintenance.
Number of units required - Larger rollouts tend to favour rental due to the upfront cost of purchasing multiple dispensers, but not always.
Expected usage levels - High-traffic areas may place more strain on equipment, making service-inclusive rental agreements more appealing.
Future flexibility - If your school is expanding or undergoing redevelopment, flexibility may be important.

A blended approach: renting and purchasing water dispensers for schools
Some schools choose to combine renting and purchasing water dispensers where it makes sense to achieve goals swiftly and within budget.
For example, it could be a good idea for your school to rent high-use units in corridors and dining areas (where maintenance demand is higher), while purchasing lower-use units in staff rooms or smaller buildings.
This approach allows schools to balance cost, control and convenience across different parts of the site.
We’ve worked on blended projects to great success in the past. For instance, at Sutton Valance School in Kent, we installed 44 new units while taking over service and maintenance responsibilities for existing school-owned dispensers. Read the full Sutton Valance case study.
Which option is right for your school - water dispenser rental or purchase?
Both renting and purchasing water dispensers can be the right choice depending on your priorities.
If flexibility, minimal maintenance and predictable costs are most important, renting is often the better fit. If long-term cost savings are the priority, purchasing may make more sense.
