Quick summary from video above:
AFDDs only required in:
-Higher risk residential buildings
-HMOs
-Purpose built student accommodation
-Care homes
Less consumer unit labelling needed, "handover pack" instead
IR tests of circuits with sensitive equipment required to be 500v with sensitive equipment disconnected, then 250v with equipment connected
RCD testing simplified to x1 on AC setting, for both waveforms. x5 test not required.
Basically don't use type AC RCDs
SPD risk assessment ditched - all installs need one unless home owner 'declares' they understand risks and don't want one.
Protected escape routes in new buildings have restrictions on services running above them
Simpler model forms
Sockets in bathrooms can be 0.5m closer bath now (3m changed to 2.5m)!!
Earth rods are now "recommended" for TNCS supplies.
