Consumer Unit Upgrade Guide for Greenock & Largs Homes

Why Upgrade Your Consumer Unit?

Old fuses, no RCD protection and overloaded circuits are accidents waiting to happen. Upgrading to a modern 18th Edition consumer unit isn’t just about compliance — it’s about protecting your family, your property and your insurance cover.
