The Compliance Hook

BS 7671 (18th Edition) recommends metal-clad consumer units for most new and replacement installations. For landlords, upgrading from an old plastic board isn't just about compliance - it's about fire safety and meeting insurer expectations. A non-compliant consumer unit can be flagged on an EICR and block re-letting. Here's what the metal-clad standard means for you.

Clear Definitions

  • Metal enclosures reduce fire risk
    Plastic consumer units can contribute to fire spread if an internal fault occurs. Metal enclosures contain flames and hot debris.
  • 18th Edition recommendation
    Regulation 421.1.201 specifies that consumer units in domestic premises should be in a non-combustible enclosure - typically steel.
  • EICR implications
    An old plastic consumer unit may receive a C3 (improvement recommended) or, in some cases, C2 if combined with other defects. Upgrading removes the risk and future-proofs the property.

The Hassle-Free Solution

We upgrade consumer units in rental properties across Margate, Ramsgate, and Broadstairs. We fit metal-clad boards with RCBO protection, issue the relevant certificates, and ensure your property meets current standards.

Landlord Pro-Tip

Combine a consumer unit upgrade with your EICR remedial work. If the EICR has flagged the board, upgrading in one visit avoids multiple call-outs and tenant disruption.
