What to Do If a Lender Withdraws Your Mortgage Offer

Having a mortgage offer withdrawn is one of the most distressing events that can occur during a property purchase. It can happen at any point before the money is transferred, and — critically — it can happen even after you have legally committed to buying a property by exchanging contracts.

This article explains how the mortgage offer withdrawal system works in the UK, what the law and regulators say about it, and what formal processes exist if you believe a lender has acted unfairly. It covers England, Wales, Scotland, and Northern Ireland where the rules differ, and it does not provide financial advice.

Mortgage lenders generally retain contractual rights to withdraw an offer at any point before completion, subject to regulatory fairness obligations. This means a lender can withdraw an offer at any point before the mortgage funds are actually released — including after you have exchanged contracts and are legally committed to completing the purchase. The Financial Ombudsman Service can investigate complaints about withdrawn offers and may award compensation where a lender is found to have acted unfairly, but there is no automatic statutory right to compensation. The processes available to you are: requesting a reason, appealing with the lender directly, and, once the lender's internal process is exhausted, making a complaint to the Financial Ombudsman Service.

The Legal Status of a Mortgage Offer

The starting point — and for many people, the most surprising fact — is that mortgage offers do not carry the unconditional legal weight that most borrowers assume they do. Mortgage offer documents typically include conditions that allow the lender to withdraw before completion. The right of withdrawal arises from those offer terms and from the regulatory framework governing mortgage lending — it is not that a mortgage offer has no legal status at all, but rather that lenders generally retain contractual rights to withdraw it before funds are released, subject to obligations of fairness.

The Financial Ombudsman Service has, across multiple decisions, recognised lenders' ability to withdraw before completion. In decisions DRN-4766029 and DRN-5283416, the Ombudsman acknowledged that lender obligations in this area arise from rules of mortgage regulation rather than from the offer creating an unconditional legal commitment. These decisions are case-specific determinations made in the context of individual complaints, rather than binding legal precedents establishing a universal rule, but they reflect how the regulatory system consistently approaches this question.

This has a direct practical consequence: a lender can withdraw a mortgage offer at any point before completion — the moment the mortgage funds are actually transferred — in circumstances permitted by the offer terms and consistent with their regulatory obligations. Once completion has occurred and the funds have been released, the offer stage ends and the mortgage contract governs the relationship thereafter. The lender's recourse in any subsequent event is through mortgage arrears and repossession procedures.

How Mortgage Conduct Is Regulated

Mortgage lending is regulated by the Financial Conduct Authority (FCA) under the Mortgages and Home Finance: Conduct of Business sourcebook, known as MCOB. While MCOB does not contain provisions that prohibit offer withdrawal as such, it does require responsible lending, accurate underwriting, and fair treatment throughout the lending relationship. A withdrawal that is inconsistent with the lender's own prior underwriting, or based on information already known at the point of offer, may be inconsistent with those regulatory expectations even where the lender has a contractual right to withdraw.

The FCA's overarching Principle 6 requires that all regulated firms "pay due regard to the interests of its customers and treat them fairly." Alongside this, the FCA's Consumer Duty — introduced as Principle 12 and in force since 2023 — requires firms to deliver good outcomes for retail customers, act in good faith, and avoid causing foreseeable harm. Both frameworks are relevant considerations when assessing whether a lender has acted fairly in withdrawing an offer. The Financial Ombudsman Service takes these principles into account when reviewing complaints. Fairness under this framework does not mean a lender cannot withdraw an offer — it means the circumstances and manner in which they do so are subject to scrutiny.

The Position in Different Parts of the UK

The legal consequences of a withdrawn mortgage offer differ depending on where in the UK the property purchase is taking place, and these differences matter significantly.

In England and Wales, a buyer becomes legally bound to complete the purchase when contracts are exchanged. GOV.UK guidance on property transactions confirms that a purchase offer made on a property is not legally binding in England and Wales until exchange of contracts — this refers to the conveyancing process between buyer and seller, not to the lender's relationship with the borrower. Once exchange has occurred, the buyer has a legal obligation to complete, regardless of what has happened to their mortgage offer. The lender is not a party to the conveyancing contract and exchange of contracts creates no obligation on the lender.

In Scotland, the legal framework operates differently. The contract becomes legally binding when missives are concluded — a process involving formal letters exchanged between solicitors — not at a point equivalent to exchange of contracts in England and Wales. Until conclusion of missives, either party may withdraw without penalty. According to Scottish legal practice, where missives include a suspensive condition such as "subject to mortgage," the buyer may in many cases withdraw from their obligations to the seller if that condition is not met. It is important to note that this mechanism relates to the buyer's ability to exit the conveyancing contract with the seller — it is a separate legal question from the lender's own decision to withdraw. The lender's withdrawal and the buyer's contractual escape route are distinct processes governed by different legal relationships. Once the conditions within the missives have been satisfied — a process referred to as the condition being "purified" — the contract becomes unconditional.

Offer Validity Periods

Mortgage offers are not open-ended. They contain an explicit expiry date, after which the offer is no longer valid. In most cases, standard mortgage offers are valid for between three and six months from the date of issue, though this varies by lender and product type. New-build mortgage offers may have extended validity periods. Once an offer expires, the lender does not need to take any active step to withdraw it — it simply lapses.

Common Reasons Lenders May Withdraw an Offer

Lenders may withdraw offers in a range of circumstances. The following situations are recognised in Financial Ombudsman decisions and FCA-regulated firm practices.

A change in the borrower's financial circumstances — such as a reduction in income, a change in employment, or the taking on of new debts — may lead a lender to reassess affordability and risk. Some lenders conduct a final credit check shortly before completion, which may reveal changes since the original application. If fraud is suspected or false information is discovered at any stage, lenders may withdraw offers immediately, regardless of how far through the process the purchase has progressed.

Where property valuation is concerned, if a property's value is reassessed downwards, or if significant defects are discovered, a lender may withdraw or reduce an offer. In some cases, rather than withdrawing entirely, a lender may impose what is known as a "retention" — holding back a portion of the funds until specific works on the property are completed. Not all lenders apply retention; some will decline the application outright in the same circumstances. The approach taken is a matter of individual lender policy. A reduced valuation can also cause issues; for guidance, see what to do if your mortgage valuation comes back low.

Changes in a lender's own policy or risk appetite — for example, the withdrawal of a product from market or adjustments to sector exposure limits — may also result in an offer being withdrawn. Financial Ombudsman cases have referenced this category of reason, and it is worth understanding that it can arise independently of any change in the borrower's own circumstances.

Notification of Withdrawal

Financial Ombudsman decisions indicate that lenders typically notify borrowers — and their brokers or solicitors — in writing when an offer is withdrawn. There is no specific timeframe mandated in FCA rules for when this notification must be given, and practice varies between lenders. However, FCA rules on complaint handling and communications still require lenders to communicate in a manner that is clear, fair, and not misleading. The absence of a mandated notice period does not mean that notification standards are unregulated.

The Financial Ombudsman Process

Before a complaint can be made to the Financial Ombudsman Service, the borrower must first exhaust the lender's internal complaints procedure. Lenders are typically given up to eight weeks to respond to a formal complaint. Only after that process has been completed — or if the lender fails to respond within the required period — can a complaint be escalated to the Ombudsman.

"Surely exchanging contracts protects me?"

This is one of the most common misunderstandings. Exchange of contracts in England and Wales creates a legally binding obligation on the buyer to complete. It does not, however, create any equivalent obligation on the mortgage lender. The lender is not a party to the conveyancing contract between buyer and seller. Exchange of contracts offers no protection against offer withdrawal.

"The lender already checked everything — can they really review it again?"

Lenders may conduct further checks before completion, but the Financial Ombudsman has been clear that this process has limits. In decision DRN-4766029, the Ombudsman found that Santander acted unfairly by withdrawing an offer when "no new information came to light" between the time the offer was issued and the point of withdrawal. The Ombudsman's reasoning was that the time for review and underwriting is before the offer is issued, not after. While lenders retain rights to withdraw, exercising that right in circumstances where nothing material has changed — and where the lender had access to all relevant information before issuing the offer — may be found to be unfair under regulatory expectations.

"Is there a legal notice period before a lender can withdraw?"

No statutory or FCA-mandated notice period has been established. There is no specific minimum period a lender must observe before withdrawing an offer, and offer terms may permit withdrawal in certain circumstances without prior notice. Lenders are nonetheless required to communicate clearly and fairly in how they handle such situations.

"Do I automatically receive compensation if an offer is withdrawn unfairly?"

There is no automatic statutory compensation scheme. Compensation is assessed on a case-by-case basis, either through the Financial Ombudsman Service or through court action. It is not guaranteed simply because an offer was withdrawn.

When the Lender Had the Information All Along

As noted above, the Financial Ombudsman has found lenders to have acted unfairly where they withdrew an offer based on information they already had access to before issuing it. In DRN-4766029, the decision made clear that proper underwriting should occur before an offer is made, not after. Where a lender withdraws an offer citing concerns that were already present in the information available to them at the point of offer, the Ombudsman may find that withdrawal was inconsistent with their regulatory obligations.

Offer Expiry as Distinct from Withdrawal

It is important to distinguish between a lender actively withdrawing an offer and an offer simply expiring because the purchase did not complete within the validity period. If an offer is approaching its expiry date, in many cases a lender may consider granting an extension, typically ranging from 30 days to three months, though extensions are not guaranteed and some lenders do not offer them. Where an extension is a possibility, published guidance from the mortgage industry suggests that requests are generally made two to four weeks before expiry. A lender granting an extension may require updated affordability checks.

The Scotland Distinction in Practice

In Scotland, where missives include a carefully drafted suspensive condition relating to the mortgage, the buyer may have a route to exit their obligations to the seller without penalty if the mortgage offer is withdrawn before the condition is purified. As noted above, this is a matter of the buyer's contractual position with the seller — it does not affect the lender's separate decision to withdraw, and the two should not be treated as one and the same issue. The precise legal effect depends on the exact drafting of the missives.

The Consequences of Failing to Complete in England and Wales

If a mortgage offer is withdrawn after exchange of contracts in England and Wales, and the buyer cannot complete, the Standard Conditions of Sale (Law Society) allow the seller to retain the deposit and, in principle, to claim further damages. Standard Condition 7.4.2(a) provides the mechanism for this. The fact that the buyer's inability to complete results from circumstances beyond their control — including a lender withdrawing a mortgage offer — does not automatically relieve them of this liability to the seller.
