Certificates that check themselves
More than sixty checks now run over gas and electrical certificates as you fill them in, and tell you what's wrong before you sign. A tightness test with no let-by before it. A property with a combustion appliance and no CO alarm recorded. A report marked UNSATISFACTORY with no C1, C2 or FI against it. A next-inspection date more than twelve months out. Each one says what's wrong, why it matters and how to fix it, ranked from blocking down to a note.
