Not simply because it is old or uses fuses. The electrician should inspect it and explain why replacement is or is not recommended. ### How much will replacement cost? It depends on the circuits, existing supply and any faults found. The survey confirms the final quote. ### Will the power be off? Yes. The supply must be isolated during the work. The duration depends on the installation and the survey findings. ### What certificate will I receive? You should receive an Electrical Installation Certificate, plus the relevant building-regulations record where applicable. ### Is a consumer unit replacement notifiable? In England, installing a new consumer unit is notifiable building work. The electrician should explain how the work will be certified and notified before it starts. ### What if an existing circuit is unsafe? A dangerous circuit must not be reconnected until it is made safe. The finding and separate remedial work are explained first. ### Do you cover my postcode?
