HOW LONG IS AN APPROVED INTERIOR QUOTATION VALID?
An approved interior quotation is generally valid for a defined period agreed between the client and the contractor. For interior projects, the validity period can depend on the scope of works, project size, material specifications, market conditions and expected project start date.
For many projects, an interior quotation may be valid for 7–30 days, depending on the scope of works and the nature of the project. The exact validity period should always be stated clearly on the quotation.
What Is an Interior Quotation Validity Period?
The quotation validity period is the length of time during which the quoted scope, specifications and terms are intended to remain applicable.
For example, a quotation may state that it is valid for 7 days, 14 days or 30 days from the date of issue.
This gives both the homeowner and contractor a clear timeframe for reviewing, approving and proceeding with the proposed project.
How Long Is an Interior Quotation Normally Valid?
An interior quotation may commonly be valid for 7–30 days.
However, there is no single validity period that applies to every interior project.
The appropriate period can depend on:
- Scope of works
- Size of the project
- Nature of the project
- Material specifications
- Availability of materials
- Customisation requirements
- Fabrication requirements
- Project start date
- Design approval requirements
A straightforward project may have different quotation requirements from a large customised interior fit-out.
Why Does an Interior Quotation Have an Expiry Date?
An interior quotation is prepared based on the project information and conditions available when it is issued.
Those conditions can change over time.
Material availability, supplier terms, hardware availability, transportation requirements and project specifications may change between the quotation date and the actual project commencement.
For this reason, quotations should not automatically be assumed to remain valid indefinitely.
A clearly stated validity period helps establish when the quoted terms should be reviewed.
What Factors Can Affect Quotation Validity?
1. Scope of Works
The more extensive the project, the more important it is to define the quotation validity period clearly.
A small installation may be easier to confirm within a short period, while a larger interior project may involve several rooms, multiple trades and detailed planning.
2. Material Specifications
Custom materials and finishes may have different availability periods.
A quotation involving specific boards, glass, aluminium systems, hardware, finishes or accessories may need to be reviewed if approval is significantly delayed.
3. Nature of the Project
The nature of the project also matters.
A standard installation may have relatively straightforward requirements, while a customised project may involve detailed measurements, fabrication, specialised hardware and several installation stages.
4. Design Changes
Changes to approved designs can affect the quotation.
If a homeowner changes dimensions, materials, finishes, layouts or specifications after the quotation is prepared, the original quotation may need to be reviewed regardless of its original validity period.
5. Project Start Date
A quotation may be approved but the project may not start immediately.
Where there is a significant gap between approval and commencement, the contractor may need to confirm that the original materials, specifications and project conditions remain applicable.
Does an Approved Quotation Expire?
There is an important distinction between a quotation that has been issued and one that has been formally approved.
If a client accepts a quotation within its stated validity period, the agreed scope and terms should be considered in accordance with the quotation and any applicable conditions.
However, if the quotation is approved after its stated validity period, the contractor may need to review and confirm it before proceeding.
The specific terms of the quotation should always be checked.
What Happens When an Interior Quotation Expires?
If a quotation expires before the project is confirmed, the next step is usually to review the original quotation.
The contractor may need to:
- Confirm that the project scope remains unchanged.
- Review material and product availability.
- Confirm the original specifications.
- Review any applicable project requirements.
- Confirm whether the original quotation can still be honoured.
- Update or reissue the quotation if necessary.
This does not necessarily mean that the entire quotation will change. It simply allows the project information to be confirmed before work proceeds.
Can an Interior Quotation Be Extended?
Yes.
A homeowner who needs more time to make a decision can request an extension of the quotation validity period.
The contractor can then confirm whether the original quotation can remain valid for the additional period.
It is advisable to have any extension confirmed in writing so that both parties have a clear record of the agreed validity period.
Why Should Homeowners Check the Quotation Validity Period?
Before approving an interior quotation, homeowners should look for the quotation validity period.
Understanding the validity period helps you know how long the quoted scope and terms are intended to remain applicable.
This is particularly important for projects where approval may involve discussions about designs, materials, financing, project scheduling or other preparations.
If you need additional time, ask the contractor whether the quotation can be extended before the stated validity period ends.
What Should an Interior Quotation Include?
A professional interior quotation should clearly communicate the proposed project requirements.
Depending on the project, this may include:
✔ Description of the work
✔ Project scope
✔ Materials and specifications
✔ Measurements or quantities where applicable
✔ Finishes and hardware
✔ Fabrication requirements
✔ Installation requirements
✔ Delivery requirements where applicable
✔ Payment terms
✔ Project timeline where applicable
✔ Exclusions
✔ Quotation validity period
✔ Terms and conditions
The exact information will depend on the scope and nature of the project.
Should You Approve a Quotation Before Checking Its Validity?
It is better to understand the quotation completely before approving it.
In addition to reviewing the total amount, check the scope of works, materials, specifications, exclusions, payment terms, timeline and validity period.
If anything is unclear, ask for clarification before approval.
This creates a clearer understanding between the homeowner and contractor before the project begins.
