OneSearch Pledge is a low-fee seller search warranty that will reimburse your client’s search costs up to £300 if the purchase of their residential property falls through. Many home buyers are simply unaware that the chance of their purchase falling through is high, and correspondingly, so is the risk of losing their search fees.

In this blog, we will look at how providing OneSearch Pledge can enhance your reputation as a conveyancer and provide considerable peace of mind to your clients that their search costs will not be lost if their transaction does not proceed. 

What is the true cost of residential property fall-throughs to the property sector? 

Nearly one in three residential property transactions fell through in 2024 (an estimated 296,204 transactions), with each one estimated to cost the home buyer an average of £3,456; that equates to losses of over £1bn. The wider economic losses due to fall through are estimated at £8.6 billion. The UK’s high property fall-through rate is not just a statistic; it represents a significant risk to your clients’ finances and your firm’s reputation and efficiency.  

Consider that for each residential property fall-through: 

  • Estate Agents lose an average of £4,123 in costs
  • Home buyers lose, on average, around £3,500 in lost fees and charges for conveyancing, surveys, and searches.

While the estimates of costs vary, it is clear that the hundreds of thousands of property fall-throughs have an enormous impact on the wider economy, property transaction stakeholders, and potential buyers.  

Why should home buyers choose OneSearch Pledge? 

1. Small fee, big benefits 

For a fee of approximately £15 per transaction, your clients can be reassured that should their matter fall through, they will receive up to £300 to cover their search costs. Given that the average cost of searches is around £400, this will return most of their search-related costs.  

2. Position for your firm as proactive and caring 

Offering a solution like OneSearch Pledge can really create a point of difference for your conveyancing practice, i.e., that you care. Many purchasers want to know that if their matter falls through for reasons outside of their control, they will not be financially out of pocket as a result. Not only does providing the assurance of Pledge show that you are committed to client care, but there will be a corresponding reduction in complaints and disputes arising from aborted transaction costs. Depending on your business model, you may choose to pass on the fee for Pledge or absorb this within your own costs in the knowledge that it may encourage more clients to choose your lower-risk offering.  

3. A refreshingly simple solution 

As far as the client is concerned, they simply need to tick the option to be covered by Pledge. There is no application form, detailed paperwork, or investment of their time. In the event that they need to claim against their Pledge warranty, all they need to do is inform their conveyancer, who will advise Onesearch. If the claim is approved, the amount is paid to the client within 15 working days. 

One small fee, no paperwork, and an easy claim process  

The exceptionally high level of fall-throughs in 2024/25 means that the risk of losing search fees is significant. While some customers will feel that they can absorb the cost of lost search fees if their matter falls through, many will not because they cannot afford to lose hundreds of pounds due to factors outside their control. By providing the peace of mind that Pledge provides, your conveyancing firm can demonstrate its commitment to customer care and respect for the precious financial resources of clients. We have made Pledge as simple as possible for all stakeholders – one small fee, no paperwork, and an easy claim process.  

Frequently asked questions 

How can I help my client understand the value of Pledge? 

Many home buyers may take the view that the risk of their purchase falling through is negligible. It is important to explain that the rate of aborted transactions is much higher than people think (i.e. nearly one-third in 2024). Furthermore, there is no guarantee that any subsequent purchase transactions will go through the first time. As a result, the fees for aborted transactions may start to add up. The fee is extremely small in the grand scheme of the purchase, but having a pledge means that they won’t waste money that can be put towards searching for a future purchase. 

Will Pledge reimburse the seller if the seller pulls out? 

Any OneSearch fees will be reimbursed to the buyer if the seller pulls out of the transaction. Specifically, we will cover the search fees if the seller is not in a legal position to sell the property or they accept a higher offer from another buyer and the home buyer is not willing to increase their offer in response. 

Will Pledge reimburse the buyer if the buyer pulls out? 

Any OneSearch fees will be reimbursed to the buyer if they need to pull out of their purchase for a wide range of reasons, including: 

  • If the searches reveal an issue that seriously affects the value of the property
  •  Due to unforeseen circumstances such as serious illness or redundancy, and
  • The property being purchased is damaged and the cost of repairs is more than 5% of the value of the property.

On the latest episode of Landmark Talks Property, we were joined by OneSearch Client Relationship Manager John Margett and Tom Lyes, Head of Legal at Armalytix, to take a deep dive into the complexities surrounding Source of Funds (SoF) and Anti-Money Laundering (AML) guidance within the legal sector, particularly for conveyancing.

The conversation unpacks the crucial ‘golden triangle’ of technology, people, and processes, emphasising that all three must be harmoniously integrated and invested in for effective AML. Tom shares his perspective on how the residential property sector has notably adapted to tightening AML pressures, even setting a precedent for other industries. Looking ahead, the discussion touches on the future of AML, including reducing duplication, the continued evolution and wider adoption of technology, the potential of Open Finance, and the ultimate aim of making UK property a robustly defended hard target against illicit funds.

Landmark’s Q1 2025 Residential Property Trends Report is now available.

This report, from our parent company Landmark, features the latest data on residential property transactions, including listings, SSTC/SSTM figures, search orders and completions.

Our data for Q1 ‘25 reveals signs of a resilient market and a stable transaction pipeline emerging following the spike in completions ahead of the Stamp Duty Land Tax (SDLT) reversal deadline in England and Wales. 

Completions rose by 30% over the quarter, with a 71% year-on-year surge in March alone as buyers rushed to complete. Beyond this much-anticipated bubble of activity, underlying indicators point to a more resilient property market heading into Q2.

The Scottish property market continued to hold firm, avoiding any notable market distortion following changes to Land & Buildings Transaction Tax (LBTT – the Scottish equivalent of SDLT).  

Other key findings from Q1 ‘25 include:

  • Listing volumes in England and Wales were comparable to Q1 ‘24, up by just 1%. In Scotland, listing volumes were up 11% for the quarter compared to Q1 ‘24. 
  • In England and Wales, SSTC volumes were down 9% compared to Q1 ‘24. Conversely, SSTM volumes in Scotland were up 9% vs Q1 ‘24. 
  • Completions were up 30% in England and Wales (+71% in March alone). In Scotland, completions were up 16% compared to Q1 ‘24.

In 2024, we witnessed steady but consistently lower transaction volumes. That begs the question: Why don’t lower volumes mean faster transactions?

Spoiler alert: aside from some marginal variances, property transaction timescales did not vastly alter in 2024, despite reduced transaction volumes. The question is: why?   

Our parent company Landmark Information Group’s latest Property Transactions Report – entitled Why don’t lower volumes mean faster transactions? – seeks to answer that question (and more), delving into 17 years’ worth of data, with cross-market commentary from our experts.  

Major talking points covered in the report include:   

  • What are the persistent bottlenecks in the home-buying process?   
  • Where have timelines improved? 
  • How do property transaction timescales compare to consumer expectations?  

In this report, we analyse the time taken between key transaction milestones and how they have changed over time, including: 

  • Instruction to completion timescales for sales and purchases 
  • Contract issued to buyer enquiries received timescales for sales 
  • Instruction to mortgage offer received timescales for purchases
