2. Important Notice
This report compares the contents of the uploaded documents only. It does not assess contractor quality, workmanship or trustworthiness.
3. Executive Summary
Quotation A has the lowest stated total, but disposal is stated as excluded, tiling is not clearly stated, and GST has not been added — the like-for-like gap to B and C is smaller than the headline totals suggest. Quotation B provides the strongest carpentry specification but prices electrical as a provisional allowance, which may change. Quotation C has the highest total and appears to include the broadest scope (ceiling works, plumbing relocation, itemised electrical), although its tile allowance may still require clarification.
5. Category-by-Category Comparison

| Flooring | Included (vinyl, grade not stated) | Included (5.5mm premium vinyl) | Included (tiles, living areas) |
| Carpentry | Included (laminate, range not stated) | Included — Blum hinges, ABS trim | Included — full spec + internal finish |

8. Possible Missing Items
- Ceiling works — not found in Quotations A and B
- Post-renovation cleaning — not found in Quotation A
- Plumbing relocation — not found in Quotations A and B; may be included elsewhere, but not clearly stated
- Disposal & haulage — stated as excluded in Quotation A
9. Ambiguous or Vague Wording
- Quotation A — "laminate finish": range/grade not stated; final selection may affect price
- Quotation B — "electrical wiring as required — allowance": provisional; actual cost may differ
- Quotation B — "selected range" sanitary fittings: brand and model should be clarified
- Quotation C — "subject to site condition" on hacking: scope of possible additions should be clarified
11. Payment-Term Comparison
- • Quotation A — 10% deposit · 40% commencement · 45% carpentry delivery · 5% completion
- • Quotation B — 20% deposit · 40% mid-progress · 40% before handover (no completion retention)
- • Quotation C — 10% · 30% · 30% · 25% · 5% on completion
A larger portion payable before handover reduces your leverage on rectification — worth discussing, not a legal conclusion.
13. Questions to Ask Each Contractor
Quotation A
- • Is GST payable on top of the $52,800 total?
- • What exact laminate range is included, and are internal cabinet surfaces finished?
- • What would disposal and haulage cost, since they are excluded?
Quotation B
- • How will the $2,500 electrical allowance be reconciled against actual points?
- • Which sanitary brand/models fall within the "selected range"?
Quotation C
- • What tile price does the $4.80/sqft allowance assume, and who supplies?
- • What site conditions would trigger additional hacking charges?
