Surveyor Negligence Claims Solicitors
A surveyor who overvalues a property, misses a structural defect, or produces a negligent RICS survey has let their client down — and their professional indemnity insurer is liable for the financial loss that negligence caused.
Surveyors — whether carrying out a valuation for a mortgage lender, a Homebuyer Report, or a full Building Survey for a buyer — owe their client a duty of care to exercise the skill and care of a reasonably competent surveyor. Where a surveyor's report is negligent — overvaluing the property, understating its defects, or missing a material structural or environmental issue — and the client relies on that report to their financial detriment, a professional negligence claim lies against the surveyor and their firm. A solicitor will assess the claim, instruct an independent surveying expert, and pursue the compensation the client is entitled to from the surveyor's professional indemnity insurer.
Surveyor Negligence — Common Types of Claim
Surveyor negligence — the most common types of claim and the financial losses recoverable from the surveyor's professional indemnity insurer.
Surveyors are engaged to identify defects and assess value — where they fail to do either and the client suffers financial loss as a result, the law provides a remedy. A solicitor will identify the specific failure, obtain expert evidence, and quantify the full measure of loss recoverable.
Negligent property valuation — mortgage lender valuations
A valuer commissioned by a mortgage lender to assess the value of a property before a mortgage is offered owes a duty of care to the lender — and, in most cases, to the borrower if the valuer's report was provided to the borrower or was known to be relied upon by them (following the decision in Smith v Eric S Bush [1990]). Where the valuation significantly overvalues the property and the borrower purchases it in reliance on the valuation, the borrower can recover the "diminution in value" — the difference between the price paid and the true market value of the property. A solicitor will instruct an independent valuation expert to assess the correct value and quantify the loss, then pursue the claim against the valuer's professional indemnity insurer.
Negligent RICS Homebuyer Report — missed defects
An RICS Homebuyer Report (now the RICS Home Survey Level 2) is a standardised survey designed to identify material defects in a property that are visible on a reasonable inspection. Where a surveyor carrying out a Homebuyer Report fails to identify a defect that would have been visible to a competent surveyor on a careful inspection — subsidence, penetrating damp, roof deterioration, structural cracking — and the buyer purchases the property in reliance on the report, the buyer can recover: the cost of remedying the defect (if they chose to proceed with the purchase); or the reduction in value of the property attributable to the defect (if the defect would have led them to negotiate a lower price or not proceed at all). A solicitor will obtain an expert surveying report identifying the defects the report should have identified and quantifying the loss.
Negligent Building Survey — missed structural and material defects
An RICS Level 3 Building Survey (formerly the full structural survey) is the most comprehensive survey available and covers the condition of all accessible elements of the property — structure, roof, services, and drainage. A buyer commissioning a Building Survey is entitled to a thorough assessment of all material defects — and where the surveyor misses a significant defect that a competent surveyor carrying out a Building Survey would have identified, the buyer has a strong professional negligence claim. The duty of care in a Building Survey is higher than in a Homebuyer Report — the client has specifically commissioned a detailed survey and is entitled to rely on a more thorough inspection. A solicitor will advise on the higher standard of care applicable and pursue the claim accordingly.
Negligent commercial property valuation
Commercial property valuations — for acquisition, refinancing, or portfolio management — must comply with the RICS Red Book (RICS Valuation — Global Standards). Where a commercial valuation is materially incorrect (outside the range of values that a reasonably competent valuer applying the Red Book methodology could have arrived at), the instructing party can recover the loss attributable to the incorrect valuation: excess loan funds advanced by a lender; loss on disposal of a property acquired at an overvalued price; or failure to recover the correct price on disposal. Commercial valuation negligence claims often involve large quantum — a solicitor will instruct a specialist commercial valuation expert and manage the litigation through to trial or settlement.
Negligent party wall surveys and boundary disputes
A party wall surveyor appointed under the Party Wall etc. Act 1996 owes a duty to act impartially between the parties in awarding the party wall — and a duty of care to the party who appointed them. Where a party wall surveyor issues an award that is negligently prepared — fails to identify existing damage, fails to impose appropriate conditions for the protection of the adjoining owner, or makes a valuation of compensation that is incorrect — the affected party can claim against the surveyor. Boundary dispute surveyors also owe a duty to give accurate advice on the position of the boundary — where a survey negligently misidentifies the boundary line and the client suffers loss, a professional negligence claim lies against the surveying firm.
Surveyors acting for lenders — the scope of the duty and the "SAAMCo cap"
The scope of a surveyor's duty of care — and the damages recoverable — is defined by the purpose for which the valuation was commissioned. Following the UKSC decision in BPE Solicitors v Hughes-Holland and Manchester Building Society v Grant Thornton, the damages for a surveyor acting as a "valuer" (not an adviser) are capped at the difference between the negligent valuation and the correct valuation — not the full transaction loss. This "SAAMCo cap" limits the surveyor's liability but does not eliminate it — a surveyor who significantly overvalues a property remains liable for the full amount of the overvaluation. A solicitor will advise on the applicable cap and ensure the claim is correctly framed to recover the maximum damages available.
