Axiom SPD consumer unit

[Thrashman]

Hi everyone, hope everyone is doing amazing and getting through this crazy time We’re living through.
So I want to see if I’m missing something here, axiom now have a 10 way dual RCD consumer unit With integral type 2SPD at a cost of £120.

They also have a 12 way dual RCD high res consumer unit with 2 spare ways at a cost of £57 and a Seperate type2 SPD for £ 26, , bringing the total cost if I add the seperate SPD into the consumer unit spare ways with dedicated MCB of £83.

am I missing something here or is it a far cheaper solution to buy the seperate items and combine ?

customer wants new consumer unit to be axiom as that’s the brand they have at another property ( job is a consumer unit upgrade ) .

excuse me if this looks like a blond question ( no offence blonds ). But don’t want to spend extra cash if the exact same can be achieved at a lower cost.

See links below for all the items

thanks in advamce

Hi guys.
I bought a pre-populated 10 way Axiom fuse board and am now told I need surge protection. I have purchased an Axiom surge protector with a little green plug on the top and a 32 amp circuit breaker. But no wiring diagram is included. Any help gratefully recieved. Garry

Did you get anywhere with this?

I have an a pre-populated 10 way Axiom fuse board that needs surge protection.
Got space for 1 module so it would be good to use this SPD which states it does not need a MCB.

Axiom make an SPD that does not need a separate MCB here:

I don't remember if it comes with the wires, but basically some 6mm for connection to Earth and Neutral is all you need.

The catch is this one comes directly off the busbar just like a MCB/RCBO - fine for main-switch and RCBO boards, but not so convenient for the older dual RCD style.
