$20,000 Workmanship Guarantee
Electrical Work Backed by a $20,000 Guarantee
When you choose BW Henderson Electrical, your residential electrical work is backed by a $20,000 Master Electricians workmanship guarantee. This guarantee is administered by Master Electricians New Zealand and provides independent assurance that your electrical work will be completed to a high standard — and if it isn’t, it will be put right.
Only Master Electricians Quality Assured members can offer this level of protection. As a result, choosing a Master Electricians member like BW Henderson means you have recourse beyond just the contractor’s word. All our electricians are also registered with the Electrical Workers Registration Board (EWRB), ensuring every job is carried out by a legally qualified and licensed tradesperson.
The Master Electricians workmanship guarantee covers residential prescribed electrical work completed by a Master Electricians member. Claims must be submitted within 12 months from either the completion date of the contract or the date on the Certificate of Compliance (CoC), whichever is later.
The guarantee covers:
- Work performed by the original contractor only
- Labour costs and replacement materials, up to $20,000 (including GST) for work completed after 1 January 2017
- Work completed before 1 January 2017 is covered up to $10,000 (including GST)
- Residential projects only
- Member workmanship — remedial work is carried out by the original contractor or an alternative member, as determined by Master Electricians
The guarantee does not cover:
- Unpaid contracts, pricing disputes, or payment disputes
- Claims where additional work, alterations, or remedial attempts were made without the original contractor’s knowledge and consent
- Issues typically covered by household insurance, professional indemnity, or public liability insurance
- Disputes under the Construction Contracts Act 2002
- Claims already submitted to statutory bodies or subject to legal processes
- Appliance repair work
If you have concerns about work that has been completed, it is recommended to first discuss them directly with the electrical contractor involved. If the matter is not resolved, a formal claim can be submitted to Master Electricians.
Claims must be submitted in writing to Master Electricians, PO Box 12434, Wellington 6144. Claims will be acknowledged within five working days of receipt. The process is as follows:
- Consumer submits a formal written claim to Master Electricians
- Master Electricians notifies the member and reviews the claim
- If the claim is accepted, an independent assessor is appointed
- The assessor arranges an inspection and site meeting
- An inspection report is shared with Master Electricians, the claimant, and the member
- If the claim is upheld, remedial work is arranged and completed
