We included companies that replace consumer units in rented homes across Greater London. Each was judged on five points relevant to landlords: certification paperwork, landlord services, pricing basis, guarantees and coverage. Research was desk-based on 27 October 2026, using company pages, Checkatrade, Companies House and published guidance. We did not test any service or ask for quotes.
Capital Electrician sits first as a publisher-selected featured pick, not as the output of a score. The other four are unranked. Landlords must keep a valid EICR: Pimlico Plumbers notes one is required every five years or on change of occupancy.

FAQs
Does a C2 on the consumer unit mean replacement? Not always. Some codes can be fixed by remedial work, so ask what the code refers to.
How long are tenants without power? Firms quote four hours to a full day.
Who notifies Building Control? A registered competent person scheme electrician self-certifies and notifies on your behalf.
Should I replace the board before or after the EICR re-test? Replace it first, then keep the Electrical Installation Certificate with your EICR. Ask the electrician whether other coded items can be cleared during the same visit to avoid a second tenant appointment.
