Understanding Electrical Quotes vs Estimates
When hiring a electrical professional, you'll encounter two types of pricing documents: quotes and estimates. Understanding the difference can save you thousands and protect you legally under Consumer Guarantees Act (CGA).
The Key Differences
Quote (Fixed Price)
- Legally binding price commitment
- Protected under Consumer Guarantees Act (CGA)
- Changes require a formal Variation
- Contractor absorbs cost overruns
Estimate (Approximate)
- Non-binding price indication
- Can vary by 10-20% or more
- Final cost determined after work
- You absorb unexpected costs
Your Legal Protection in NZ
Under Consumer Guarantees Act (CGA), a written quote is generally considered a binding offer. Once you accept it, the contractor cannot increase the price without your written agreement through a Variation. The Commerce Commission can help if a contractor tries to charge more than the quoted amount.
Always ensure your quote includes the contractor's NZBN and clearly states whether GST is included in the price.
Local Insight for NZ
In New Zealand, the Consumer Guarantees Act provides strong protections—services must be carried out with reasonable care and skill. For building work over $30,000, a written contract is required under the Building Act. Always check the LBP (Licensed Building Practitioner) register for restricted building work.
