SPD in a plastic consumer unit.

[Pat H]

Adding an EC charger and looking at options to include an SPD.
The consumer unit is plastic (but in good condition)
Options seem to be to add an SPD (with isolator and MCB) before the consumer unit.
Or add an isolator before the EV charger with an SPD, isolator and MCB.
Or can an SPD be added in the consumer unit?
There is room in the consumer unit but as it's not metal (so not 27th ed) not sure that's allowed.

I can't see any real reason for not being able to add an SPD internally to the consumer unit, as long as it's not going to make it any less safe.
