Proptech Backs 28-Day Exchange Push as Delays Cost Deals

e4 Strategic has signed up to the Project 28 Charter, lending its VERSA digital conveyancing platform to an industry-wide push to compress the gap between sale agreed and exchange of contracts to just 28 days. For a market where the average transaction in England and Wales still takes between 12 and 20 weeks from offer to completion, this is a meaningful commitment from a proptech provider whose infrastructure touches lenders, conveyancers and estate agents simultaneously.

The significance for investors and professional landlords extends well beyond administrative housekeeping. Every week added to a transaction chain represents mortgage rate risk, chain collapse exposure and holding costs that erode yield. Industry estimates suggest roughly a third of sales agreed in England fall through before completion, with delay — not price renegotiation — cited as the single largest cause. For buy-to-let landlords assembling or disposing of portfolios across multiple properties, compressed timelines translate directly into reduced void periods between purchase and tenancy, and lower exposure to rate movements between mortgage offer and drawdown.

VERSA's role illustrates where the real friction sits: not in legal complexity but in fragmented communication between parties who historically relied on email, post and phone calls to pass information that should move instantly. By digitising workflows between mortgage lenders, conveyancing solicitors and estate agents, the platform aims to eliminate the searches backlog, ID verification delays and mortgage offer renewal cycles that routinely stretch transactions well past the 12-week mark. Charter members effectively commit to benchmarking their own processes against a 28-day standard, creating competitive pressure across the conveyancing sector to adopt similar digital infrastructure or risk losing instructions to faster-moving rivals.

Regional disparities in transaction speed remain stark and will shape how quickly this initiative delivers measurable impact. London and the South East, including high-value Surrey markets, tend to suffer the longest delays owing to more complex chains, higher-value mortgage underwriting and greater reliance on leasehold conveyancing with its attendant management company enquiries. By contrast, more transactionally straightforward markets in Manchester, Leeds and Newcastle — where a higher proportion of sales involve first-time buyers and simpler freehold titles — are better positioned to approach the 28-day benchmark quickly once digital workflows are adopted at scale. Birmingham and Liverpool, both experiencing strong investor demand from portfolio landlords capitalising on yields above 6% in some postcodes, would benefit disproportionately from faster exchange given the volume of investment purchases competing for the same stock.

For developers and commercial investors, the implications are equally material. New-build completions are frequently delayed not by construction but by the conveyancing tail, with reservation-to-exchange periods eating into sales momentum and cash flow forecasts. A genuine industry shift towards 28-day exchange would allow housebuilders to recycle capital faster and reduce the incentive discounting currently used to keep chains together. Commercial property transactions, while structurally different, would benefit from the same underlying principle: any technology that reduces due diligence friction between institutional parties shortens the gap between agreed heads of terms and completed transfer, lowering transaction risk premiums currently priced into deal structures.

Over the next six to twelve months, expect Project 28 Charter membership to become a marketing differentiator among estate agents and conveyancers competing for instructions, particularly as mortgage brokers steer time-sensitive remortgage and bridging clients towards faster-processing chains. The Charter's success will ultimately be measured not by the number of signatories but by completion data: if average exchange times genuinely compress towards four weeks across a critical mass of transactions, mortgage lenders will likely respond by tightening offer validity periods, confident that longer buffers are no longer necessary. That would further reinforce the shift, creating a virtuous cycle between digital infrastructure and lender risk appetite.

The direction of travel is unambiguous: transaction speed is becoming a genuine competitive battleground in UK property, not merely a service-quality talking point. Firms that fail to digitise conveyancing workflows within the next 12 to 18 months risk losing volume to platforms like VERSA that can demonstrably deliver faster, lower-risk exchanges — and investors would be wise to favour agents and conveyancers who can evidence Charter-aligned completion times when selecting transaction partners.
