Cable Locator Cost-Benefit Analysis
The cost of a cable locator is trivial next to the cost of a strike. A single cable strike in the UK averages thousands of pounds in direct repair, plus downtime, investigation and potential HSE action. Against that, a calibrated CAT and Genny, whether hired, refurbished or new, pays for itself the first time it stops a spade hitting a live main.
Cable avoidance is one of the rare site investments where the business case is overwhelming. Here is how the numbers actually stack up.
What does a strike really cost?
The repair bill is only the visible part. A strike typically brings:
- Direct repair of the damaged service, often charged back by the utility.
- Site downtime and standing labour while the area is made safe.
- Investigation, paperwork and possible HSE involvement.
- In the worst cases, serious injury, which puts everything else in perspective.
Even a "minor" strike routinely runs to several thousand pounds. A serious one is an order of magnitude worse.
Hire, refurbish or buy: which is most cost-effective?
| Option | Best when | Rough cost profile |
|---|---|---|
| Hire | One-off jobs, short projects, peak demand | Low per-day, no capital outlay |
| Refurbished | Regular use, best value ownership | Around half the price of new, calibrated |
| New | Large fleets, latest features | Highest outlay, longest service life |
Where do the ongoing costs sit?
The honest running cost of ownership is calibration: budget for an annual calibration and service per unit, plus the occasional battery and accessory. That is a small, predictable figure, and it is non-negotiable, because an uncalibrated unit is a liability, not an asset.
The simple payback
Set the lifetime cost of a calibrated locator against the cost of one avoided strike and the maths is not close. For a team that digs regularly, refurbished ownership gives the lowest cost per use; for occasional work, hire avoids tying up capital. Either way, the locator is the cheapest insurance on site.
