What are you spending to stay compliant?
Most estates cannot answer that in one number, because the cost is split across inspection contracts, reactive repairs, premature replacements and the admin time that holds it all together. Put your door count in. We’ll show you all four.

A one-page PDF with your figures, the line-by-line comparison and the assumptions behind it. Useful for the conversation you’ll need to have internally.
Door count carries into the demo booking — you won’t be asked twice.
Four lines, not one.
The device fee is a new cost. It is smaller than what it removes, and the removal happens in four separate places.
Inspection
Physical visits go where the data says a door needs one. The blanket sweep stops being the default.
Remedial
A closer caught drifting is an adjustment. Caught six months later it’s a strip-and-refit.
Replacement
Doors replaced because their condition is unknown are the most expensive doors in the estate.
Admin
Evidence assembles itself. The week before an audit stops being a week.
