According to the way I read it. As of May 2018, hid bulbs in a headlamp designed for halogen headlights will be an automatic mot failure.
"Some vehicles may be fitted with High Intensity Discharge (HID) headlamps. It is not permitted to convert existing halogen headlamp units for use with HID bulbs. If it is clear that such a conversion has been carried out, rather than replacing the entire unit with one designed and approved for use with HID bulbs, the headlamp should be rejected."
