Adding a second consumer unit

Anonymous user 23/02/2024 - 3.16 PM

On the assumption that there are no stupid questions... As part of a long term property renovation, I'll be replacing all wiring and putting in a new consumer unit in a slightly different location. But this won't all be happening at once. My question is, is it advisable (or even possible) to add a second consumer unit, leaving all existing circuits on the original CU for now, adding each new circuit to the new CU as and when they are addressed, and them eventually taking out the old one completely? My logic being that this avoids me wasting time and money rewiring the existing circuits into a new CU in a new location, only to redo it all later, and avoids wiring the new circuits into the existing CU for the same reason. Make sense?

Well, a garage consumer unit is a sub board. Just a bit concerned you are thinking of doing this without knowledge of electrical design.

Long and short of it is yes you can. Making sure that along the way the cabling complies. Dont forget this includes the supply conductors to the secondary board. It is notifiable works. Regards Matt Gatwick Electrical

Hey, Technically you can add an additional distribution board ( sub board ) as this is often the case when a customer requires electrical work that must comply with current 17th edition regs without the expense of a new consumer unit. What you are proposing is slightly different however as you are over time planning to migrate the circuits from one board to another. Whilst possible you may wish to consider how the supply cables are routed and fused and to ensure there are no parallel paths between distribution boards. Hope this helps Ben
