Digital reform could transform purchase timelines – opinion

The UK housing market has always been complex, but the latest data from UK Finance makes clear that we have entered a particularly pressured period. The Lending Where We Live report reveals that homebuyers are now spending an average of 21.3% of their gross income on mortgage repayments, the highest level since 2008. When buyers are stretched this thin, the stakes of every transaction have never been higher – delay is no longer just an inconvenience, but a significant financial risk.

Why affordability makes speed and certainty critical

Affordability pressures fundamentally change the financial dynamics of the homebuying process. When a buyer is committing more than a fifth of their gross income to repayments, the period between offer and completion becomes acutely exposed to rate fluctuations, mortgage offer expiry, and changing personal circumstances. This is not just a purchase market problem as remortgaging customers rolling off fixed-rate deals face the same vulnerability, with every week of unnecessary delay creating mounting costs.

And yet, the average listing to completion time in 2025 took between 185 -205 days nationwide. This relates to the best-case scenarios. Worst case, approximately one in four (23%) of property sales fall through before completion, further delaying the process and costing the economy £1.97 billion each year. In a market where affordability headroom has been eroded to its narrowest point in almost two decades, these failure rates and timescales are not simply operational inefficiencies. They represent a systemic amplification of financial risk for buyers, sellers, and lenders alike. The longer a transaction takes, the more opportunities there are for chains to collapse, mortgage offers to expire, and confidence to erode.

The infrastructure problem

It is tempting to attribute delays solely on capacity constraints such as overworked and highly stressed conveyancers, brokers and lenders, backed-up local authority searches or slow communication. While those pressures are real, the deeper issue is structural. The UK’s transaction infrastructure remains, in large part, a paper-based, sequential, disconnected process that was not designed for the pace or complexity of today’s market.

The UK is the slowest of the world’s dozen most developed countries for the time taken to complete a property sale from listing to completion. In Australia, for example, transactions typically complete in four to six weeks, with minimal fall-through rates, thanks to trust, standardisation and robust digital infrastructure.

Data from the Home Owners Alliance shows that one in five homeowners experience moving day delays due to late transfers of funds, with households across the UK incurring a total cost of over £15 million. This is a solvable problem. What is needed is a shift from fragmented, manual processes towards a model where all parties operate within a shared, connected digital environment in which fund settlement, title registration, and transaction data flow together in near real time.

Collaboration is the key ingredient

Technology alone, however, is not sufficient. The reason the UK’s transaction process has remained slow and fragmented for so long is not a lack of available solutions.  It is the challenge of coordinating implementation at scale. That is beginning to change.

The roadmap developed through the recent Open Property coalition, led by the Centre for Finance, Innovation and Technology (CFIT), and backed by the Department for Business and Trade (DBT), Open Property Data Association (OPDA) and industry players, is an example of a major initiative that aims to boost the digitalisation of the home buying process. The Government believes the process could eventually be reduced to as little as four weeks in straightforward cases, but achieving this requires all parties to be rowing in the same direction, sharing data, aligning standards, and removing the friction points that sit between each stage of a transaction.

The question is no longer whether the UK’s property transaction system needs to change. With buyers in the most severely stretched affordability position since the financial crisis, and with international comparators demonstrating that faster, more certain completions are entirely achievable, the case for action is clear. The challenge now is execution, and that requires the whole industry to move together.
