Itemised hot water system replacement example

Each amount is its quantity multiplied by its AUD unit rate, rounded to cents. These 7 entries match the fixture used to make the PDF. Metric surface and length units describe the priced work, not a conversion rule for another property.

Hot water system replacement example — AUD Work item | Quantity | Unit rate | Amount |

Site review and protection | 1 job | A$224.00 | A$224.00 |

Existing tank removal | 1 each | A$336.00 | A$336.00 |

Replacement equipment allowance | 1 each | A$1,470.00 | A$1,470.00 |

Connection-material allowance | 1 job | A$308.00 | A$308.00 |

Installation labour | 1 each | A$868.00 | A$868.00 |

Commissioning and handoff | 1 job | A$196.00 | A$196.00 |

Tank disposal and cleanup | 1 job | A$266.00 | A$266.00 |

Subtotal / example total | A$3,668.00 |

Calculation check: 1 job × A$224.00 = A$224.00; 1 each × A$336.00 = A$336.00. The demonstration tax field is 0%, so the displayed total stays A$3,668.00. Determine tax and markup for your own work instead of using this input as guidance.

Assumptions and scope boundaries

The equipment line is an illustrative allowance. Match the actual product and required accessories to supplier information before the estimate becomes a final purchase commitment.

Outside this example: No fuel conversion, service upgrade, new vent route, concealed piping repair or unlisted approval and inspection fees.

Selections, access or concealed conditions that differ from this scope require a revised quantity, allowance or separate line. The example deliberately separates them so the client can see what has and has not been priced.

Common questions about hot water system replacement

Can a tank replacement be priced from capacity alone?
