MORTGAGE GUIDANCE
Mortgage offers are normally valid for a limited period. If a purchase or remortgage does not complete before the offer expires, you may need to ask whether the lender will extend it or reassess the application.

Your home may be repossessed if you do not keep up repayments on your mortgage.
How long does a mortgage offer last?
Validity periods vary between lenders, products and circumstances. Your mortgage offer should state its expiry date or relevant completion requirements.
Check the expiry date and any completion conditions shown in your mortgage offer rather than assuming all lenders use the same timescale.
What happens if my mortgage offer expires?
An expired offer does not automatically continue. Depending on the lender and circumstances, you may need an extension, a reassessment with updated information or further underwriting, or a new mortgage application. An extension is not guaranteed.
Can I extend my mortgage offer?
Some lenders may consider extending an offer where completion has been delayed, but policies and requirements vary. They may consider the reason for the delay, how long is required, changes in circumstances, updated documentation, another valuation, and changes to the product or criteria.
Why might completion be delayed?
Property chain
Another transaction in the chain may delay completion.
New-build property
Construction or completion may take longer than expected.
Legal work
Conveyancing enquiries or legal matters may remain outstanding.
Property issues
Valuation, survey or title matters can require further investigation.
What if my circumstances have changed?
Changes to employment or income, financial commitments, deposit, property or purchase price, or borrowing required can be relevant. Provide information required by the lender and do not assume an existing offer remains unaffected by a material change.
What if my mortgage offer expires when I’m remortgaging?
Timing can matter when remortgaging, particularly where a fixed or discounted period is ending or an early repayment charge applies. If a new offer expires before completion, discuss available options and timing again.
