Existing Rear extension conservatory upgrade with new flat roof.
Anonymous user 12/11/2026 - 1.27 PM
My builder is connecting new wiring to existing circuit in the new extension for spots, switches, sockets, hob/Oven. He's used connectors and not running a new separate circuit because my circuit board has no space. Is this okay? Would I need a certificate for the new modifications from the builder?
Are you a tradesperson and able to answer this question?

No it’s not ok your consumer unit should have 20% free space for new circuits, this is going against the wiring regulations

Yes you would need a certificate, which certificate would depend on exactly what he’s done
