The Court of Appeal’s recent decision in Bratt v Jones [2025] EWCA Civ 562 represents a significant clarification of the legal principles governing professional negligence claims against property valuers. The case concerned a professional negligence claim brought against a valuer following a development site valuation that resulted in a significantly lower purchase price than the claimant anticipated. Despite the valuation being substantially below the claimant’s expectations, the Court of Appeal unanimously dismissed the appeal, reinforcing the established two-stage test for valuer liability and confirming that the burden of proof remains firmly with the claimant throughout.

Court of Appeal Confirms Approach to Professional Negligence Claims Against Valuers
Bratt v Jones represents a significant reaffirmation of established legal principles governing professional negligence claims against property valuers. The Court of Appeal’s unanimous decision provides clarity on several key issues:
- The two-stage test remains binding – both bracket breach and Bolam negligence must be proven
- The burden of proof never shifts – claimants must prove both elements
- Bracket determination is factual – expert evidence determines appropriate margins
- Methodological criticism requires specificity – general complaints about outcomes are insufficient
The decision will provide reassurance to valuers whilst emphasising the importance of professional competence and proper methodology. For claimants, it reinforces the need for robust expert evidence and specific pleading of negligence allegations.
The Option Agreement and Valuation Exercise
Mr Bratt owned a development site in Oxfordshire with planning consent for 82 residential units across approximately 10 acres. The site was subject to an option agreement with Banner Homes Limited, granting the developer the right to purchase at 90% of the market value as determined by a third-party valuer if the parties could not agree on price.
When Banner Homes exercised their option in June 2013, the parties jointly instructed Mr. Jones as an independent expert to determine the market value. Mr. Jones employed two standard methodologies:
- Comparable sales approach – relying primarily on the Bloxham Road comparable
- Residual valuation method – calculating the site’s value based on gross development value minus development costs
Mr. Jones’s final valuation of £4,075,000 resulted in a purchase price of £3,529,500 after the 90% reduction and agreed deductions.
The Dispute
Mr. Bratt contended that the true market value was approximately £7.8 million (with a 10% margin of error placing it between £7 million and £8.6 million), representing a potential loss of millions of pounds. He alleged that Mr. Jones’s valuation was negligently low and fell outside any reasonable margin of error.

The High Court Decision
HHJ Mark Cawson KC’s Findings
His Honour Judge Mark Cawson KC, sitting as a High Court Judge, conducted a thorough analysis of the expert evidence and reached several key conclusions:
- Correct Market Value: The judge determined that the most likely true market value was £4,746,860
- Permissible Margin: He established a margin of error of 10-15% either side of the correct value
- Actual Deviation: Mr. Jones’s valuation was 14.15% below the court’s determined correct value
- Negligent Methodology: The judge found that Mr. Jones had made an error in his treatment of “enhancements” that would have caused a £495,000 loss
Despite identifying methodological errors, the judge dismissed the claim because the valuation fell within the permissible bracket of non-negligent valuations.
Appeal Ground 1: Legal Test for Liability
Mr. Bratt’s primary argument centred on the legal test for establishing negligence. He contended that once a valuation falls outside the permissible margin, the burden of proof should shift to the valuer to demonstrate they were not negligent.
The Court of Appeal firmly rejected this submission, confirming that the legal burden remains with the claimant throughout. The two-stage test established in Merivale Moore plc v Strutt & Parker remains binding:
- Stage 1: The valuation must fall outside the acceptable bracket of values
- Stage 2: The claimant must prove the valuer breached their Bolam duty of care
Ground 2: Determination of the Bracket
The appellant argued that bracket determination should be a question of law rather than fact, with the margin capped at 10% for this type of valuation.
The Court of Appeal clarified that bracket size is a question of fact to be determined by the court based on expert evidence. The guidance from K/S Lincoln provides general principles rather than strict legal rules:
Professional Negligence Standards: Property Valuation vs Other Professions
- Standard residential properties: ±5%
- One-off properties: ±10%
- Properties with exceptional features: ±15% or higher
Ground 3: Enhancements and Abnormal Costs
Mr. Bratt challenged the judge’s treatment of building enhancements and abnormal costs, arguing these adjustments were incorrect and would have placed the valuation outside the permissible bracket.
The Court found the judge’s approach was supported by expert evidence and that the complaint was insufficiently pleaded to warrant interference.
Ground 4: Comparable Evidence
The final ground contested the judge’s reliance on the Bloxham Road comparable, arguing that Aynho Road and Milton Road should have been considered.
The Court held that no expert had provided the necessary detailed analysis to adjust these comparables for relevant differences, making any comparison exercise impossible.

Key Legal Principles Established
The Nature of Valuation
The Court reaffirmed that property valuation is an art not a science, with competent valuers often reaching different conclusions without negligence. This fundamental principle underpins the entire legal framework governing valuer liability.
The Two-Stage Test Confirmed
The decision firmly establishes that both elements must be proven:
- Objective: Valuation outside the permissible bracket
- Subjective: Breach of professional duty under Bolam principles
The “Logical Fallacy” Acknowledged
Significantly, the Court acknowledged a “logical fallacy” in the current framework, noting that a valuer could be negligent but escape liability if their valuation falls within the bracket. However, they deferred resolution of this issue to the Supreme Court, citing binding precedent from Merivale Moore.
Future Developments in Claims Against Negligent Valuers
Potential Supreme Court Review
The Court of Appeal’s acknowledgment of the “logical fallacy” in current law suggests this area may require Supreme Court clarification. The tension between methodological negligence and outcome-based liability remains unresolved.
Legislative Considerations
The government’s approach to professional negligence regulation continues to evolve, with potential implications for limitation periods and expert evidence requirements.
