Consumer unit upgrades and fuse board replacement.

BIM Electrical Group upgrades old fuse boards, replaces unsafe consumer units and installs modern circuit protection for homes, landlords, HMOs and commercial premises across London, Essex and the South East.

Modern protection for safer installations.

The consumer unit is the main control point for the electrical installation. If it is damaged, outdated, poorly installed or missing suitable protection, it can lead to failed EICRs and increased electrical risk.

We install modern consumer units with suitable protective devices, clear labelling, testing and certification.

Consumer unit upgrades are often carried out as standalone works, as part of an EICR remedial package, during refurbishment or before a property is rented out.

We can help with:

  • Consumer unit upgrades.
  • Fuse board replacements.
  • RCBO consumer units.
  • RCD protection upgrades.
  • Surge protection devices.
  • Landlord electrical remedials.
  • Failed EICR consumer unit issues.
  • Testing and certification.
TESC registered compliance workflow

BIM Electrical Group can register EICR outcomes and remedial progress through The Electrical Safety Council database where required.

When does a consumer unit need upgrading?

A consumer unit upgrade may be recommended after an EICR, before property rental, during refurbishment or where the existing board is no longer suitable.

Failed EICR

Older boards, poor protection, damaged enclosures or unsafe circuit arrangements can contribute to an unsatisfactory EICR.

Missing protection

Modern installations often require suitable RCD or RCBO protection depending on the circuits and installation conditions.

Rental properties

Landlords often upgrade consumer units as part of EICR remedial works before letting or renewing compliance documentation.

Consumer unit replacement after a failed EICR

Not every failed EICR means the consumer unit must be replaced. However, some reports identify issues that make an upgrade the most practical route to compliance.

We review the report, check the existing installation and advise whether repair, alteration or full replacement is the correct option.

Common consumer unit issues include:

  • Old rewireable fuse boards.
  • Missing RCD protection.
  • Damaged consumer unit enclosures.
  • Incorrect circuit labelling.
  • Poor cable entries.
  • Mixed or unsuitable protective devices.
  • No spare capacity for future works.

Already have a failed EICR?

Send us the report and we can quote the consumer unit works alongside any other electrical remedials needed to close out the report.

This is especially useful for landlords, agents and managed properties where the remedial works need to be handled quickly and documented clearly.

Consumer unit FAQs

Common questions about fuse board replacement and consumer unit upgrades.

Do I need to replace my old fuse board?

Not always, but older fuse boards may need upgrading where they are damaged, unsuitable, missing required protection or causing issues on an EICR.

Can a consumer unit cause a failed EICR?

Yes. Consumer unit defects, missing RCD protection, damaged enclosures or unsafe arrangements can contribute to an unsatisfactory EICR.

Do you issue certification?

Yes. Consumer unit upgrades are tested, labelled and certified as part of the works.

Can you quote from photos?

In many cases, photos of the existing consumer unit and surrounding area help us give initial advice before attending.

Send us details of the property and the existing fuse board or consumer unit. Photos are useful if you have them.
