How We Compared
We evaluated each platform on the features that matter most to UK letting agents: UK compliance tracking (gas safety, EICR, EPC), separate portals for tenants, landlords, and tradesmen, built-in communication tools, electronic signing, pricing transparency, and ease of getting started.
This comparison is focused on platforms commonly used by UK letting agencies managing residential rental properties. We've excluded enterprise-only platforms and those primarily aimed at commercial property.

What Matters Most When Choosing
UK compliance tracking should be your top priority. Without it, you're managing expiry dates in spreadsheets and hoping nothing slips through. One missed gas safety renewal can cost you your reputation and your licence.
Separate portals save you hours of admin. When tenants can report issues directly, landlords can view their properties online, and tradesmen can access their job list—you spend less time fielding phone calls and emails.
Pricing transparency matters for smaller agencies. Per-property fees that seem cheap at £5/property quickly add up as your portfolio grows. Flat-rate plans give you predictable costs.
Built-in communication (SMS and email) means you're not paying for separate tools or copying messages between systems. Everything stays in one place, with a complete audit trail.
