Two UK Remortgages Have Just Completed Using Programmable Money. What Could Change for Borrowers?

The mortgage itself was still a mortgage. The money was still sterling held through regulated banks. What changed was the way the completion funds could be controlled: locked in advance and released automatically when the transaction reached the agreed point.

UK Finance announced on 24 September that banks had completed the first live customer transactions using tokenised sterling deposits through its Great British Tokenised Deposit initiative.

Barclays, HSBC UK, Lloyds Banking Group, Monzo, Nationwide, NatWest and Santander participated. The first live retail transactions included two remortgage completions and a separate transaction between a consumer and a private seller.

This is not a new mortgage product that borrowers can select today. It is a live pilot of payment infrastructure. Its significance is that real customer money moved through the system in completed remortgage transactions rather than the concept existing only in a technical demonstration.

What Is a Tokenised Sterling Deposit?

The phrase sounds more complicated than the customer experience needs to be. A tokenised deposit is a digital representation of money held at a commercial bank. In this case, it represented sterling deposits—not Bitcoin, a speculative cryptoasset or a separate private currency.

UK Finance says the money retains the trust and regulatory protections associated with conventional bank deposits. The additional capability is programmability: rules can govern when the payment moves and what conditions must be satisfied first.

Think of it as ordinary bank money with an agreed digital instruction attached. Instead of several parties separately confirming that conditions have been met and then initiating the movement of funds, the payment can be arranged to execute when the required event occurs.

The underlying legal, regulatory and operational details are more complex, but the borrower-facing benefit is potentially simple: greater certainty about where the money is, why it is locked and when it will move.

Why Mortgage Completion Still Creates Friction

Mortgage applications have become increasingly digital. Identity documents can be uploaded, bank information can be shared electronically and valuations may sometimes be completed remotely. Yet the final transfer of money still depends on several organisations and instructions aligning at the correct moment.

On a remortgage, the new lender must provide the advance, the existing mortgage must be redeemed, legal conditions must be met and any balance must be dealt with correctly. Conveyancers need accurate redemption figures and confirmation that funds have arrived. Banks must verify payment instructions. Each manual hand-off can add time or create uncertainty.

Most transactions complete without serious difficulty, but the process can be stressful because a borrower may know the mortgage has been offered while remaining dependent on a chain of events that happens largely out of sight.

Programmable settlement does not remove the need for those conditions. It could make the movement of money respond more directly once they have been satisfied.

What “Locked Until Completion” Means in Practice

In the pilot, funds could be reserved for the transaction so they were available when needed, but released only when the relevant completion conditions were satisfied. That creates a form of conditional payment.

For a borrower, the important idea is certainty without premature transfer. The money is committed to the transaction, but it does not need to move through every stage of the process before completion is ready.

UK Finance also identifies the possibility that funds can continue earning interest while held in the customer’s account until completion. That may be modest on an ordinary balance held for a short period, but it becomes more material where substantial sums are involved.

The conditions themselves still have to be accurate, legally valid and properly authorised. Automation can execute a rule consistently; it cannot compensate for a poorly designed rule or incomplete legal work.

Could It Reduce Payment Fraud?

Property transactions are attractive to fraudsters because large payments are made under time pressure. Criminals may impersonate a solicitor, bank or client and attempt to substitute false payment instructions.

A system in which funds are locked for a defined purpose and released to a verified destination when agreed conditions are met could reduce the opportunity for last-minute instruction changes. UK Finance lists reduced fraud as one of the potential benefits demonstrated by the pilots.

It would not eliminate every form of fraud or cyber risk. Identity, access controls, data integrity and the governance of the platform remain critical. A new infrastructure can remove some vulnerabilities while introducing others that must be controlled.

The relevant claim is therefore measured: conditional settlement may reduce particular payment and instruction risks. It is not a guarantee that property transactions become fraud-proof.

What Could Change for Conveyancers?

Conveyancers sit at the point where legal completion and movement of funds meet. Any technology that changes settlement therefore affects their workflow more directly than the mortgage-advice stage.

Potential benefits include fewer manual confirmations, clearer evidence that funds are available, less reconciliation and a more reliable audit trail. Digital connectivity with HM Land Registry could eventually make the payment and registration stages more closely aligned.

The pilot does not make legal professionals redundant. Conveyancers still need to investigate title, satisfy lender requirements, verify clients, manage redemption and confirm that the transaction can complete. Programmable money changes how an authorised payment is executed; it does not decide whether the legal conditions should be treated as satisfied.

Professional responsibility will also need clear boundaries. Firms will want to know who defines the release conditions, who confirms them, how errors are corrected and what happens if the technology or one participant is unavailable on completion day.

Why This Matters More on Large or Time-Sensitive Transactions

The same settlement problem exists whether a remortgage is £200,000 or £20m, but the financial and operational consequences increase with the size and complexity of the transaction.

On a large refinance, substantial sums may be needed to redeem an existing bank, release additional capital or coordinate several secured facilities. There may be multiple lawyers, private banks, investment managers and ownership entities involved.

For a bridging exit, delay can mean another month of comparatively expensive interest or an approaching facility expiry. For a high-value purchase, uncertainty around funds can affect an entire completion chain. Faster or more dependable settlement could therefore have disproportionate value in specialist finance.

That is a future possibility, not a service Willow or the participating banks are presenting as generally available today. The first two remortgages establish that the mechanism can operate with live customers; they do not establish the timetable or terms for widespread adoption.

What This Does Not Change About a Remortgage

Technology cannot make an unaffordable mortgage suitable or repair a weak application. The borrower still needs the right loan, acceptable property, evidence of income and a lender prepared to approve the case.

The valuation, underwriting, mortgage offer, legal title and redemption of the existing charge remain fundamental. Early-repayment charges, product fees, interest rates and the purpose of any additional borrowing still determine whether the remortgage makes financial sense.

It also does not mean every completion should become instantaneous. Some conditions exist precisely because money should not move until legal and financial checks are complete.

The innovation sits at the end of the journey. It may make settlement more efficient once the advice, underwriting and conveyancing work has produced a transaction that is genuinely ready to complete.

What Happens Next?

UK Finance says further pilots are expected over the coming months. The next stage will explore settlement involving digital assets, including digital debt instruments and coupon payments made using tokenised deposits.

For mortgages, the important questions are practical. Can the infrastructure work across a much larger number of banks and law firms? How will conditions be standardised? How will systems interact with Land Registry processes? Who carries responsibility when data is wrong or completion must be reversed?

Customer adoption will depend less on the word “tokenisation” than on whether the process is demonstrably safer, quicker and easier. Most borrowers will not care which infrastructure sits underneath completion if it gives them clearer information and fewer delays.

Questions Borrowers and Property Lawyers Should Ask

How Willow Private Finance Can Help

There is no tokenised-deposit mortgage for Willow to recommend as a standard product today. Our role remains to identify the appropriate mortgage, coordinate the lender requirements and work with the client’s solicitor towards completion.

For borrowers planning a residential remortgage, the immediate priorities remain rate, total cost, borrowing capacity, timing, property and the reason for refinancing. A more efficient payment system would improve the final stage, but it would not replace suitable mortgage advice.

For conveyancers and professional partners, the pilot is worth following because it may alter how lenders, banks and lawyers coordinate completion. Willow welcomes early discussion on complex or time-sensitive refinances so the mortgage and legal workstreams can be aligned before the completion deadline becomes critical.
