Do You Need a Fuse Board Upgrade in Renfrew?
Renfrew's long-established town centre sits alongside post-shipbuilding riverside development further out — a mix that means older-style fuse boards are still common in parts of the town, particularly in properties that haven't had electrical work done in some time. If you're not sure whether your board needs upgrading, we're happy to take a look and give you an honest answer either way.
- An older-style fuse board is still fitted
- You're experiencing electrical faults or frequent tripping
- Renovation or extension work is underway
- The property is being prepped for rental
- You need additional circuits or improved safety protection
