consumer unit installation
what is the cost to install anew consumer unit, transfer the main supply and do the part P testing and sign off?
Expert Trade Answers
"The overall price would vary depending on the number of circuits in the consumer unit and whether any wiring faults become apparent before or after the upgrade. New consumer units generally contain more stringent fault detection that can capture more faults than older units.
A full EICR (Electrical Installation Condition Report) would be required post-installation of the new consumer unit. This activity covers the Part P you mention and the local authority building control may need to be notified of the work and the competence of those carrying out the work
If "transfer of the main supply" just means reconnection of the main supply tails from the meter, then that would all be included in the price of the installation/upgrade.
As a guide and depending on location and complexity, price for the entire works required could be in the region of £500 - £750."
