Overview

About this service

Wooden-back fuse boards, plastic enclosures and unprotected circuits are common in London properties built or rewired before 2008. Leon Electricians Ltd upgrades fuse boards to modern metal-clad consumer units with full RCBO protection, surge protection and proper circuit labelling - usually within a single day.

What we do

Consumer unit replacement

Strip out the old board, install a new metal enclosure and re-terminate all circuits cleanly.

RCD & RCBO upgrades

Add proper residual current protection to circuits that currently have none.

Surge protection devices

Protect sensitive electronics from lightning and grid spikes.

Circuit labelling & testing

Every circuit tested, labelled and recorded on the certificate.

When to call us

  • Your fuse board has rewireable fuses or a wooden back
  • The board is plastic and pre-2008
  • You have no RCD protection on socket circuits

FAQs

Common questions

We isolate the property while we swap the board - usually 4–6 hours without power. We try to schedule around work-from-home needs and can stage the work where possible.
