Consumer Unit Upgrades in Greenwich & Blackheath

Why Greenwich Homes Need Consumer Unit Upgrades

Greenwich has a varied housing stock — Victorian and Edwardian terraces, 1930s semis, post-war housing estates and newer builds — and a significant proportion of properties still have electrical installations that haven't been properly updated. Old consumer units with ceramic rewirable fuses, or plastic units with no RCD protection, fail to meet current safety standards and often flag as C2 (potentially dangerous) on an EICR.

A modern consumer unit provides RCD protection on every circuit, housed in a metal enclosure as required by the 18th Edition Wiring Regulations. This protects against electric shock and limits the spread of fire if a fault develops inside the unit.

Signs Your Consumer Unit Needs Replacing

• Ceramic fuses or an old Wylex-style board with rewirable fuses
• No RCD switches on the board — only MCBs
• Plastic consumer unit (metal enclosures are now required)
• Frequent tripping or a board that won't hold its switches up
• An EICR that has graded the consumer unit as C2
• You're a landlord and the certificate is due for renewal

What We Install

We fit dual-RCD or fully RCBO-protected consumer units from established manufacturers in a metal enclosure. Every circuit is individually tested before the supply is restored. The job typically takes 4–6 hours for a standard 3–4 bedroom property.

All work is notified under Part P of the Building Regulations and you receive an Electrical Installation Certificate the same day. This is required for planning compliance and proof of certification for landlords.

Pricing in Greenwich

Most consumer unit replacements in Greenwich and the surrounding SE postcode areas come in between £350 and £600 depending on the number of circuits and whether any additional work is required at the same time. We quote a fixed price before we start — no adjustments on the day.
