Changing kitchen downlights from 12v to 230v & part P

[squelch41]

Hi,
I am planning to change some downlights in a kitchen from 12v MR16 canisters to 230v GU10 fittings. I am using the original wiring (just removing the transformers obviously!) and there will be the same number of lights in the same places.
Does this require part P notification or does this come under "minor work"?
Also, do the 230v fittings have to be canisters or can open backed ones be used?
Thanks

now if you put in 230v lamps, and depending how many you have may trips you teeny weeny 6A breaker so changing circuit charcteristics...... coulod b consideration for notifying.. but now im making this all up

but if its in a kitchen with a room above then they should certainly be fire rated
