Engineer was very untidy (he discarded old PAT testing labels in various places around our premises and we had to go around after him picking them up and disposing of them) He also took it upon himself to report back to management about additional services that the company then approached us about. We felt that this was underhanded and would've preferred it if the engineer asked our permission to take notes on our fire extinguisher equipment and circuit boards. We thought he was here to do our PAT testing? I would have to think twice about allowing this company access to our premises again.
