Hire vs Buy a Generator: Which Makes Financial Sense?

Hire vs Buy a Generator: Which Makes Sense?

Whether to hire or buy depends on how often you need the generator, how long each job runs, and whether you want the ongoing responsibility of maintenance and storage. Both options have clear financial and operational trade-offs.

Quick Comparison

| Factor | Hire | Buy | | --- | --- | --- | | Upfront cost | Low (deposit + hire fee) | High (full purchase price) | | Ongoing cost | Pay per use | Fuel + maintenance only | | Maintenance | Included | Your responsibility | | Delivery & setup | Included | Your responsibility | | Storage | Not needed | You store it | | Flexibility | Swap sizes per job | Fixed to one unit | | Best for | One-off or occasional jobs | Regular, ongoing use |

When to Hire

Hiring is the better choice when:

• You need a generator for a one-off project or short-term job
• You need different sizes for different jobs
• You don't want the upfront capital cost of buying
• You don't want to handle maintenance, storage or transport
• You need delivery and setup included
• You're not sure what size you need yet

When to Buy

Buying is the better choice when:

• You use a generator regularly or for ongoing work
• You need a standby generator permanently installed for backup
• You want to avoid ongoing hire fees that exceed the purchase price
• You have the storage and maintenance capability
• You want the generator available on demand without booking

The Break-Even Point

A rough rule of thumb: if your total hire costs over 12-18 months would exceed the purchase price of a generator, buying becomes more cost-effective. For a 6.5kVA portable diesel at around $3,000-$4,000 to buy, that break-even point typically falls around 4-6 months of regular weekly use.

For standby generators that run automatically during outages, buying is almost always the right choice — you need it permanently installed and ready.

Hidden Costs of Ownership

When buying, factor in:

• Annual servicing — typically $200-$500 for a portable unit
• Repairs — engine and alternator wear over time
• Storage — secure, weatherproof space when not in use
• Transport — you move it between sites yourself
• Insurance — if included in business assets

Hiring includes all of these in the hire fee.

Our Recommendation

For one-off projects, occasional use or uncertain sizing, hire. For regular use, standby backup or permanent installation, buy. Not sure? Get a quote and we'll help you work out the numbers for your situation.
