SDLT COMPASS LIMITED

What SDLT COMPASS LIMITED does

SDLT Compass Limited (trading as 'Compass') is a UK-based technology and services company founded in 2021 that provides software and outsourced services for Stamp Duty Land Tax (SDLT) calculation, risk assessment, and HMRC submission. It targets UK property professionals — primarily law firms and conveyancers, with secondary segments including mortgage brokers/IFAs, estate agents, auction houses, and homebuyers — supporting residential, commercial, mixed-use, leasehold, and additional property transactions. The Concierge PMC service also covers LBTT (Scotland) and LTT (Wales). The company is privately held, founder- and management-owned with no disclosed institutional funding, and operates from a single Mayfair, London headquarters.

The platform is organised as three tiers: SoftCheck (instant RAG-scored risk assessment delivered in under 10 seconds), Gateway (indemnified per-transaction SDLT calculation with expert oversight), and Concierge (full-service outsourced SDLT department in which Compass acts as the named HMRC tax agent). A free quote tool drives lead generation and referrals to partner law firms. The underlying technology is a proprietary rules-based engine applying 49+ SDLT reliefs and surcharges, maintained in real time by UK SDLT specialists over a 7+ year development cycle, with HMRC-aligned SDLT1–5 form generation, multi-buyer scenario analysis, and £1,500,000 of professional indemnity cover per engagement including three-year run-off.

Revenue is generated through a hybrid model: per-transaction fees for Gateway (scaled by property value and complexity), flat-fee per-matter pricing for Concierge, and PAYG or subscription for SoftCheck, with a free quote tool creating affiliate-referral leads back to law firm partners. Distribution combines enterprise direct sales to conveyancing teams, a self-serve client portal at client.compass.tech, a partner-embedded white-label quote tool, and a 2026 technology integration with InfoTrack. Customer logos disclosed on the website include Farnworth Rose, BG Solicitors, Searchess UK, ABS Solicitors, EG Law, Williams Thompson, Jasper Vincent, Pearson, Adoor, and PSD Solicitors, with named strategic partnerships referencing Farnworth Rose (March 2025) and BG Solicitors (July 2026).

• LexisNexis (UK Legal): Major UK legal practice management, research, and compliance technology provider. Comparable as a large incumbent selling workflow and compliance tools into UK law firms that could expand into SDLT-specific functionality within its conveyancing practice suite.
• InfoTrack: UK conveyancing and legal technology platform providing document ordering, due diligence, and workflow tools to law firms. Comparable as both a distribution partner and a broader legal-tech incumbent that could plausibly build or acquire SDLT-specific functionality within its conveyancing stack.
