Consumer unit upgrades are one of the most important electrical improvements you can make to your Essex home. Here's what homeowners in Burnham-on-Crouch and Chigwell need to know.

Consumer Unit Upgrades in Burnham-on-Crouch

Burnham-on-Crouch is a historic market town on the Dengie Peninsula with a significant proportion of older housing stock. Many properties in Burnham-on-Crouch still have outdated consumer units — either old rewirable fuse boards or early RCD-protected units that don't meet current standards.

Signs you need a consumer unit upgrade in Burnham-on-Crouch:

Old ceramic rewirable fuses rather than modern circuit breakers.
A single RCD protecting all circuits (rather than dual RCD or RCBO protection).
No surge protection device (SPD) — now required under the 18th Edition Wiring Regulations.
Consumer unit identified as requiring upgrade on an EICR.

Consumer Unit Upgrades in Chigwell

Chigwell is an affluent village in the Epping Forest district with a mix of older and newer properties. Older properties in Chigwell frequently have consumer units that are 20–30 years old and no longer compliant with current regulations.

A modern consumer unit upgrade in Chigwell provides:

Individual RCBO protection for each circuit — if one circuit trips, the rest remain live.
Surge protection device (SPD) — protects sensitive electronics from voltage spikes.
Compliance with the 18th Edition IET Wiring Regulations.
A 10-year manufacturer warranty on the consumer unit.

What's Involved in a Consumer Unit Upgrade?

A consumer unit upgrade typically takes 4–6 hours for a standard domestic property. Our engineers: 1. Isolate the supply and remove the old consumer unit. 2. Install the new consumer unit and connect all existing circuits. 3. Test every circuit to confirm correct operation. 4. Issue an Electrical Installation Certificate. 5. Notify the work to the relevant authority under Part P.
