What people hire it for.
Prove rated output on new install.
Witness testing to ISO 8528.
Burn off unburnt fuel on lightly-loaded sets.
Scheduled black-building tests and standby-set proving for NHS and private healthcare sites.
Level 4 & 5 IST loading for new-build and expansion halls, proving generators, UPS and cooling under real load.
Booking a 3.3 MVA load bank shouldn't be harder than booking a hotel room.
See live availability on our calendar and reserve the unit for exactly as long as your commissioning window needs.
On request, we can deliver the unit directly to your site, position it where you need it, terminate cables and run a witnessed pre-load check. Delivery, connection and witness checks are optional add-ons and quoted separately.
Full 0–3.3 MVA resistive loading with step control and data logging. Run the test with your own team, or leave the hassle to one of our expert engineers — either way you get 24/7 phone support from a real engineer.
Transparent day rates.
Standard delivery: £4.50/mile from Leeds LS16 depot. Weekend mobilisation available on request.

- How much notice do you need?
- 48 hours for standard UK mainland mobilisation. Emergency same-day dispatch is possible — call our 24/7 line.
- Do you supply the cabling?
- Yes — 240 mm² Powerlock tails are available at £20 per set of 4 cables per day.
- Can I load-test lower than 3.3 MVA?
- Absolutely. Step resolution is 10 kW so you can trim right down for 250 kW sets upwards.
- Is an engineer included?
- No — an engineer is not included as standard, but one can be added to your hire. See the booking form for engineer day rates and to add them to your quote.
- What about power factor testing?
- Yes — this is a combined resistive / reactive unit rated 2,640 kW real and 1,980 kVAr reactive at 0.80 power factor.
