A four-surveyor practice in a market town in the east of England, fee income around £840,000, with a mixed practice of valuation, building consultancy and a meaningful element of land and development consultancy serving local landowners, developers and agricultural clients.
The firm was instructed by a longstanding landowner client to prepare for the sale of a parcel of land at the edge of the client’s wider estate — approximately 4.2 hectares earmarked for residential-led development pending planning consent. The instruction included the preparation of a sale plan to be used in marketing and incorporated into the eventual transfer documentation, and a tender process for development buyers.
The sale plan was prepared by the firm’s land team using a base from the client’s existing estate plans, with measurements verified against current Ordnance Survey mapping and the firm’s own site walk. The plan showed the parcel boundary running along an existing post-and-rail fence on the western edge. The boundary, as drawn, was approximately consistent with the fence line. However, the OS mapping showed the registered title boundary of the parcel running approximately 14 metres to the west of the fence — incorporating a strip of land between the fence and the actual title boundary that was occupied as part of the neighbouring landowner’s farmyard.
The firm did not engage with the discrepancy. The marketing plan, the tender documentation and ultimately the transfer plan showed the boundary as the fence line. The land was sold for approximately £1.6m to a regional housebuilder.
The discrepancy came to light when the buyer commissioned a topographical survey for the planning application and identified the inconsistency between the transfer plan and the registered title. The strip of land in question turned out to be a critical part of the developer’s site for planning purposes — without it, the achievable plot count fell by three units.
The neighbouring landowner — properly identifying that he had been treating the strip as his land for over a decade — declined to sell or rent the strip to the developer on commercial terms and engaged solicitors in respect of his own potential adverse possession position. The developer claimed against the firm’s client; the firm’s client claimed against the firm.
The chain of claim was: developer against landowner-seller (the firm’s client) for breach of sale contract and misrepresentation; landowner-seller against the firm for the negligent preparation of the sale plan. The principle from Hedley Byrne governed the firm’s duty; the Bolam standard, in the surveying-specific application, set the standard against which the firm’s preparation of the plan was assessed.
The expert evidence on both sides agreed that the standard for a sale plan prepared by a chartered surveyor includes a positive duty to engage with the registered title position and to flag any discrepancy between physical features on the ground and the registered title. The firm had not done that.
Quantum was complex. The settlement between developer and landowner reflected the reduced plot count, the additional planning and design costs, and a contribution to the developer’s costs in dealing with the neighbouring landowner. The landowner’s onward claim against the firm sought to recover the bulk of the settlement plus the landowner’s own costs. Headline quantum was approximately £540,000.
Section 5 notification was made on receipt of the landowner’s pre-action letter. The wording responded subject to the firm’s £15,000 excess. The £2m limit was sufficient.
The defence was carefully constructed. The firm’s defence solicitors and their expert ran the position that the firm had been instructed in respect of marketing and tender, not in respect of formal title due diligence — which would conventionally be the work of the landowner’s solicitors using HM Land Registry title plans and any necessary boundary determination. The argument had real force but was undercut by the firm’s own correspondence — emails between the firm and the client confirming the firm “would prepare a definitive plan for transfer”. The case settled at mediation.
A coverage question arose on section 11 Insurance Act 2015. The firm’s wording contained a condition precedent requiring the firm to “comply with all professional regulations and RICS standards” in the conduct of its work. The insurer (rightly) did not seek to rely on this provision; section 11 prevents insurers using non-compliance with a term to escape liability where the non-compliance is not relevant to the loss, and in this matter the breach (if any) of RICS standards was the very subject of the loss rather than a collateral non-compliance.
The matter settled at mediation at approximately £395,000 inclusive of the landowner’s costs.
The settlement was paid. The firm overhauled its sale-plan procedure: all sale plans are now checked against HM Land Registry title plans before issue, any discrepancy is flagged in writing to the client, and the scope of the firm’s instruction is documented to make clear whether the firm is or is not undertaking definitive title verification.
The firm’s PI premium rose by approximately 32% at renewal. The firm continues to do development consultancy work but with materially clearer scoping of instructions.
Boundary and plan errors are a small share of overall surveying claims but have an outsized average quantum. First, the surveyor’s scope on land and development instructions should be set out in writing with explicit treatment of the boundary and title-verification questions; ambiguous scoping is where claims are seeded. Second, the registered title position is the legal boundary, not the physical features on the ground; a sale plan should engage with both and document any discrepancy. Third, where a discrepancy exists, the firm’s duty is to flag it to the client and recommend specialist legal or boundary determination — not to silently reconcile it. Fourth, the firm’s PI wording should be checked for any conditions precedent that could be relied on to deny cover; section 11 of the Insurance Act 2015 provides important protection but the contractual structure of the policy still matters. Fifth, the renewal narrative for land and development specialists requires care; underwriters distinguish between firms with disciplined scoping and clear documentation and firms that operate on a more elastic understanding of their instructions.
We would have framed the section 5 notification with care, ensuring the firm’s scoping defence was preserved without conceding ground. At the defence stage we would have introduced surveying-defence counsel with deep experience of land instructions rather than general PI counsel, where the difference is real. At renewal, the firm’s revised scoping procedure and the audit-trail evidence are the documents that the specialist surveyors’ PI markets value — and the difference between a 32% rate movement and one closer to 50%.
