How long does a mortgage offer last? Your formal mortgage offer sets the deadline for your purchase. Find the expiry date in your latest offer and compare it with the date you expect to complete. If the seller proposes a later date, check that your lender can still release the funds in time.
Imagine your seller asks to move completion back by a fortnight. That sounds like a small change, but it could take you beyond your mortgage deadline. Before agreeing, give the new date to your broker and conveyancer. They can check different parts of the problem.
How long does a mortgage offer last with your lender?
Start with the latest formal offer for the home you intend to buy. Look for the property address, the issue date, the expiry date and any conditions. If you cannot find a clear deadline, ask your lender or broker to identify it in writing.
Use the exact date shown on the offer when planning your move. Counting forward from the day you applied, or relying on another buyer’s experience, could leave you working to the wrong deadline.
Which document are you holding?
An agreement in principle gives an initial indication of how much you might borrow. It can help when you start looking at homes. However, it has its own validity period and does not confirm funding for a specific purchase.
A formal offer follows the lender’s assessment of your application and the property. By contrast, an estate agent’s email confirming your offer on the house records the seller’s response to your bid. Keep the three documents separate, even if everyone calls each one an “offer”.
If your lender sends revised paperwork, compare the issue date, reference, property and conditions with the previous version. Then ask which expiry date applies. A change to the document does not, by itself, tell you how much extra time you have.
How long does a mortgage offer last if the property changes?
If you switch to a different home, tell your broker before using the old deadline in your plans. Your existing formal offer names the property the lender assessed. Ask whether it will need a new valuation or application and when it can confirm revised terms.
For example, you might lose one purchase but find another home at the same price. The loan amount may look familiar, yet the lender still needs to consider the new property. Wait for confirmation before giving the seller a firm mortgage timetable.
What should you check before exchange?
In England and Wales, the purchase becomes legally binding when you exchange contracts. At that point, the completion date matters to both buyer and seller. Your conveyancer can explain what a proposed date means under your contract. Read the GOV.UK guide to making an offer on a home for the distinction.
First, put the expiry date and proposed completion date in the same email. Ask your conveyancer whether any outstanding searches, enquiries or lender conditions could affect the timetable. Next, ask your broker what the lender needs before it can release the money.
Leave room for practical arrangements. For example, ask when your conveyancer plans to request the mortgage funds and what they still need from you. Even if completion falls before expiry, an outstanding document could leave less time than your calendar suggests.
A worked example using 28 June and 4 July
Suppose your offer expires on 28 June. You originally expected to complete on 20 June, but the seller now proposes 4 July. The change moves completion from eight days before expiry to six days afterwards. The issue is the gap between the new date and your written offer.
The practical question goes beyond “how long does a mortgage offer last?” Ask whether your lender can release funds on 4 July.
Give your broker both dates, your mortgage reference and the reason for the delay. Meanwhile, tell your conveyancer whether the parties have exchanged contracts. Ask the broker when the lender expects to make a decision. Ask the conveyancer what you can safely agree while you wait.
If someone says the extra days should be fine, ask what supports that answer. Is there a published lender policy that applies to this offer? Has the lender confirmed an extension for your case? Those answers give your conveyancer something specific to check.
Can you extend a mortgage offer?
Some lenders consider extensions. However, each sets its own process, deadlines and checks. An extension request alone does not give you a new expiry date. Ask who must submit the request, what evidence the lender wants and when you should expect a reply.
If you applied through a broker, send them the revised completion date and ask them to check the extension process for your offer. If you applied directly, contact your lender’s mortgage team. Ask for written confirmation of the new expiry date and any conditions before agreeing a revised timetable.
What to put in an extension enquiry
- Your case details. Include the mortgage reference, the property address and the expiry on the latest offer.
- The new timetable. Explain the reason for the delay, the proposed completion date and whether you have exchanged.
- Any changes. Tell your broker about changes to income, borrowing or the purchase. Ask which documents the lender needs.
- The answer you need. Ask for the applicable deadline, any new conditions and written confirmation.
If the lender asks for new payslips, a valuation or a fresh application, ask what that means for the rate and timing. Also check whether any fees apply. Keep your conveyancer informed before committing to a revised date or booking services you cannot cancel.
How long does a mortgage offer last on a new build?
A new-build purchase adds a second timetable. Your lender gives you a mortgage deadline, while the developer may give you a window for finishing the property. Compare the end of that window with your expiry date as well as checking the developer’s preferred date.
If the developer gives you a completion window, ask your broker to check what happens if the property is ready after your offer expires. Find out whether your lender will consider an extension for this purchase or require a fresh application. Give your conveyancer the lender’s written response.
Suppose the developer initially expects a September handover but later gives a window extending into November. Ask for the latest dates in writing. Then ask your conveyancer what notice the contract allows and your broker how those dates fit the mortgage offer.
What if you have exchanged or the deadline has passed?
Contact your conveyancer promptly if you have exchanged and think you might miss completion. Explain what changed and what the lender has confirmed so far. Your conveyancer can review the contract and set out the options and implications for you.
If the expiry date has already passed, tell your broker or lender immediately, even if the delay seems minor. Ask whether the lender can still release funds for your case. If it requires a new application, ask which documents, checks and costs you should expect.
Meanwhile, keep one shared record of the dates and confirmations. A short email with the lender’s reply and the revised completion date can prevent misunderstandings between the chain, broker and conveyancer. Keep sensitive financial documents in the channel your broker or lender provides.
Questions buyers ask about mortgage offer expiry
How long does a mortgage offer last after the lender issues it?
Use the expiry date printed on your latest formal offer. If you have revised paperwork or the deadline is unclear, give your broker the offer reference and ask them to confirm the last date you can complete.
How long does a mortgage in principle last?
The lender sets its validity period and usually shows the date on the agreement or confirmation. Check it before making an offer on a home. You still need a full mortgage application and a formal offer for the property.
What happens if my mortgage offer expires before completion?
Tell your lender or broker and your conveyancer as soon as the dates look set to overlap. Ask what your lender will accept and get its decision in writing. If you have already exchanged, ask your conveyancer about the contract implications straight away.
What to do with your dates today
If you are buying your first home, keep your formal offer somewhere you and your conveyancer can find it. Record the expiry and proposed completion date together. When either date changes, update both your broker and conveyancer.
Your home may be repossessed if you do not keep up repayments on your mortgage.
