Talk to a landlord who has been fined and the story is almost never that they did not know the rule. It is that a date passed while they were doing something else.
Gas safety runs annually. An electrical installation condition report runs to five years, and five years is long enough to forget entirely. Energy performance certificates expire on their own schedule. Deposit protection has a deadline measured in days. Licensing depends on where the property is and changes when the council decides it does.
Five clocks, none of them aligned
That is what makes this hard for someone with two or three properties rather than two hundred. A portfolio manager has a system. A landlord with a day job has a drawer, and the clocks do not line up in a way any drawer can hold.
The failure is rarely dramatic. It is a certificate that expired in March and got noticed in September, at the point where a tenant asked or something went wrong.
A calendar that knows what applies
Tradelynx tracks the statutory obligations per property and tells you what is due before it becomes overdue, rather than reporting that it already is.
Where a certificate can be confirmed against an official register, it is, and it is marked verified at source only when it genuinely matched. Where it cannot be, the record says so instead of implying a check that never happened.
What it costs
The compliance calendar is free and self-serve. It takes a few minutes per property to set up, and the setup is the only part that needs you.
You are not buying a promise that you will never miss anything. You are removing the reason people miss things, which is that nothing was watching the date.
