These warranty terms apply to Evopower and Hyundai 1500rpm diesel generator sets distributed by Genpower Ltd, Isaac Way, Pembroke Dock, Pembrokeshire, SA72 4RW, United Kingdom.
These terms apply to generator sets registered and used in UK-based applications. If you require overseas warranty terms, please contact us.
Important: extended regions (Highlands, Islands and other extended postcode areas)
Units located in the Highlands, Islands or other extended regions of the UK may incur additional costs/surcharges regardless of whether the fault is later confirmed as a warranty issue. Examples can include (but are not limited to):
- engineer call-out or travel contributions
- collection/return carriage contributions
- parts delivery surcharges
If you are unsure whether your location is considered an extended area, please contact us before purchase.
Warranty summary (limited warranty duration)
A) Standby applications (Hyundai and Evopower UKC ECO 1500rpm generators)
Standard cover: 12 months / 1,000 hours (whichever occurs first) for parts and labour.
Optional standby extension (where eligible): may be extended to 24 months for standby use, limited to a maximum of 500 hours per year.
- The second year is parts-only.
- To activate the second year, Genpower Ltd must receive a fully completed service record sheet within 30 days of the start of year 2 (i.e., within 30 days after the 12-month anniversary of the warranty start date), together with proof of service and operating hours.
B) Alternator warranty (Genpower and Hyundai alternators only)
Alternators supplied as:
- Genpower alternators fitted to the Evopower Cummins UKC ECO range, or
- Hyundai alternators used on Hyundai 1500rpm units distributed by Genpower Ltd
are covered by a 3-year limited alternator warranty, excluding AVRs.
This alternator warranty covers genuine manufacturing defects only and does not cover failures caused by incorrect use or conditions, including (but not limited to) phase imbalance, corrosion due to dust/sea air/moisture, improper storage, or rapid/consistent overloading or underloading.
For an alternator warranty claim, we require:
- a copy of the control panel configuration/parameters confirming they remain in factory settings, matching our pre-dispatch test results, and
- evidence/history showing settings have not been changed since dispatch.
If your unit has a different alternator brand, refer to that alternator manufacturer’s warranty guide.
C) Prime applications (Evopower UKC ECO Cummins-powered generators only)
For prime power applications of the Evopower Cummins-powered UKC ECO range only, the warranty is 12 months or 2,000 hours (whichever occurs first), provided:
- service intervals have been met and maintenance completed,
- servicing is completed by an approved service provider, and
- within 14 days of each service, the buyer or service contractor sends proof to sales@evopower.co.uk, including:
- a photo of the hours clock, and
- proof of service work completed (e.g., invoice showing approved/genuine parts such as Fleetguard filters and the work carried out).
If you are unsure whether your application is classed as standby or prime, please contact us before commissioning.
1) Warranty start date and transferability
All warranty periods begin on the date of dispatch from Genpower Ltd.
Warranties are not transferable.
If you purchased via a dealer/reseller and are unsure of the dispatch date, contact us and we will advise what we have on record.
2) What to do if there is a fault (procedure)
If a fault or breakdown occurs, you must contact Genpower Ltd with details of the issue by:
- telephone or email, or
- completing the relevant repair/warranty form on evopower.co.uk or hyundaipowerequipment.co.uk
If you cannot use the online form, contact us and we can provide an electronic or hard-copy form.
We may request (at our discretion):
- photos/video evidence
- return of faulty parts for assessment
- in exceptional cases, return of the unit for diagnosis
In most cases, a clear description and photographic evidence are sufficient for an initial warranty decision.
If the fault is deemed warrantable and cannot be resolved by technical advice, we will arrange for an approved engineer to attend and repair the unit.
Engineer attendance and regional contributions
If the unit is in an extended region (e.g., Highlands/Islands), a contribution towards engineer travel/call-out and/or carriage may apply. Any such contribution will be discussed with you before arrangements are confirmed.
Target response times (service-level targets)
These timescales are targets we aim to meet (not a guarantee and not a contractual remedy if exceeded):
- We acknowledge receipt of an online submission within 2 working days (excluding weekends and public holidays).
- An in-house engineer will contact you within a further 2 working days to discuss troubleshooting.
- We will aim to confirm whether we believe the fault is warrantable within a further 1 working day, and agree next steps (remote support, parts dispatch, engineer visit, etc.).
If we arrange an engineer visit, we may ask you to acknowledge that if the fault is later confirmed as non-warranty, the engineer’s fees and associated costs may be chargeable.
If we advise the fault appears non-warranty, you may choose to use your own engineer to repair the unit.
3) Warranty request form (information required)
Your warranty request should include (as applicable):
- generator serial number and model number
- start-up / commissioning report
- current hours
- customer name and address
- generator location (if different from customer address)
- clear description of the fault and supporting photos/diagrams where possible
Providing complete information upfront helps us make a faster decision and reduces the risk of avoidable engineer call-outs.
