Key takeaways

  • New lines work best when they go out on the same delivery as your plant.
  • Each line has its own inspection rules: PAT testing for tools, gas safety for some welfare units, LOLER for lifting kit.
  • Test demand with a few units or cross-hire before buying in volume.
  • Every line must make money on its own, including handling and delivery.

Why add a new line

  • Raise the value of each delivery.
  • Become the one supplier a site calls for everything.
  • Use spare yard, transport and admin capacity.
  • Smooth seasonal demand.

Inspection and compliance

  • Electrical tools: inspection and testing between hires (often called PAT testing).
  • Lifting and access equipment: LOLER thorough examinations. See PUWER and LOLER.
  • Welfare units with gas appliances: gas safety checks by a qualified engineer.
  • Fuel bowsers: bunding and storage rules. See environmental compliance.
  • Waste from toilets and welfare: licensed waste handling.

Testing demand

  1. 01

    Ask existing customers

    What else do they hire, and from whom?

  2. 02

    Cross-hire first

    Supply it from another firm for a few months. See cross-hiring.

  3. 03

    Buy a small batch

    Two or three units, not twenty.

  4. 04

    Measure utilisation

    Same break-even test as plant.

  5. 05

    Expand or stop

    Based on the numbers, not enthusiasm.

Making the decision

A new line is worth it if it earns its own margin after handling, inspection, delivery and loss, and doesn't distract from the plant fleet that pays the bills. See plant vs tool hire for how the businesses differ.

FAQs

Common questions

Should a plant hire company add tool hire?
It can, if tools go out on the same deliveries as plant and earn their own margin after testing, cleaning and losses. Test with a small range first.
Is welfare unit hire profitable?
Welfare units often go out on long hires, which helps utilisation, but need servicing, waste handling and suitable transport. Test demand before buying several.
What inspections do hire tools need?
Electrical tools need inspection and testing between hires, lifting and access equipment needs LOLER thorough examinations, and gas appliances need gas safety checks.
