You probably need an upgrade if:
Your consumer unit is plastic or very old
You have rewireable fuses / no modern protection
Circuits trip often
You need an EICR pass (landlord / sale / compliance)
You’re renovating, extending, adding EV/loads
Quick check: Send a photo of your current board on WhatsApp — we’ll tell you straight.
A consumer unit replacement isn’t “swapping a box”.
It’s testing the circuits and making sure the installation is safe and compliant.
If someone quotes cheap and skips proper testing… you pay later.

Slav replaced my old plastic fuse board with a safe new metal one, tested the whole flat, and sent me the safety certificate that same day. He explained everything very clearly, worked neatly and professionally, and left me feeling completely at ease. I finally have peace of mind knowing my electrics are safe.
