How Long Is a Building Quote Valid?
There is no single fixed period. Each quote should state its own. Here is why, and what to do if yours is about to run out.
The short answer
As long as the quote says. Look for the date on it.
A building quote is valid for whatever period the contractor states on it. There is no single period set by law, so each business chooses its own, and a well-written quote says clearly how long the price stands. If a quote gives no period, the general position is that an offer lapses after a reasonable time and can be withdrawn before you accept it, so it is worth asking.
Accepting within the validity period, clearly and in writing, is the simplest way to hold the contractor to the price. This is general information, not legal advice.
The reason
Why quotes carry an expiry date
A quote is priced on the day it is written. Material prices move, the contractor's diary fills, and a job that is left for months can change: a small leak becomes a bigger one, or the season turns. A validity period tells you how long the contractor is prepared to stand behind today's figure.
It works in your favour too. A stated period gives you time to read the quote properly, compare it with others and ask questions without being pushed into a decision on the doorstep. For what to check in that time, see what to do before accepting a quote.
If you are not ready to go ahead within the period, say so. A contractor would usually rather know than be left waiting, and an honest conversation about timing often leads to a sensible arrangement, such as a revised quote nearer the time.
Worth knowing
Three things about validity
Check the date it runs from
Validity usually runs from the date the quote is issued, not from the site visit. Note the last day somewhere you will see it.
Validity is not a start date
Accepting within the period fixes the price for the work described. When the work starts is a separate thing to agree.
An expired quote isn't void
Once the period has passed, the contractor can revise the price. Many will honour it or update it with little change. Just ask.
Running short of time
If your quote is about to expire
Ask for more time before it lapses
A short extension is often possible, especially if you explain why. Get any extension confirmed in writing.
If it has already lapsed, ask whether the price still stands
If it doesn't, ask what has changed. A revised price should come with a reason. Our answer on what happens if the price goes up covers this.
Re-check the scope
If time has passed, make sure the work described still matches what you need, particularly if the problem has changed.
Accept clearly
When you are ready, accept in writing and keep a copy. A dated email that refers to the quote is enough to show when and what you accepted.
After you accept
What acceptance fixes
Accepting a quote within its validity period generally fixes the price for the work it describes. The price can still move later if the work itself changes, or if the quote included allowances for things that couldn't be priced yet. See can a builder change the price after quoting? and is an estimate legally binding?
Deciding in time
Using the validity period well
A validity period is time to think, not a countdown to pressure you. Use it to read the quote properly, compare it with any others, check the contractor and ask about anything unclear. If you need longer, it is better to ask early than to let the date slip by unnoticed.
Be cautious of any offer that expires within hours or "today only". A fair quote gives you a reasonable window to decide. If you are being pushed to sign on the spot, it is sensible to step back. Our sister guide on what paperwork to get before work starts covers what to have in hand.

Straight answers
Questions about quote validity
Can a contractor withdraw a quote before it expires?
In general, an offer can be withdrawn before it is accepted. Accepting promptly and in writing is the practical way to avoid that. This is general information, not legal advice.
If I accept on the last day, does the price still stand?
Generally, yes, if you accept within the stated period. Accept in writing and keep a copy showing the date.
Should the quote say when the price was calculated?
It helps. A clear issue date and a stated validity period tell you exactly how long you have. If either is missing, ask for it in writing.
