You can do it relatively well in front of a garage door. To test height the MOT man should get you to sit on the bike and measure to the centre of the headlamps. Take this height and pencil line it on the garage door. The cut off of the light should be below the line at about 4m. There are some slight variances for different bulb heights but good enough rule of thumb. Of course this doesn’t check the dip left / right kick.
