So am i correct than reg 443.4 means unless we provide a risk assesment that states why we are not using a spd in consumer unit changes then we must fit one??

That’s how I interpret it.

Not sure how you can carry out a risk assessment however because it states that you have to do a calculation with the different lengths of each element of the distributions various cable lengths.

Lpal, Lpcl, Lpah & Lpch

Other than asking the DNO not sure how these can be determined.

So I guess the only real way is to add type 2 devices to each CU adding £200+ to each job?
