De-risk your practice. Strengthen your reputation. Protect your clients.
SDLT errors are one of the most common – and costly – threats in conveyancing. Misclassification, missed reliefs, or miscalculations can lead to:
 • Underpaid SDLT, risking loss of property, HMRC challenge, or PI exposure
 • Overpaid SDLT, leading to lengthy reclaim processes and client dissatisfaction
 • Reputational damage and increased insurance costs
 • Delays, rework, and unnecessary administrative burden for your team
