Marks above old consumer unit

[Mike07]

Hi all,

We have quite an old consumer unit and noticed some weird grey marks above it (please see picture). We’ve recently painted this area and over the grey marks but they’ve come back through. Does anyone think these marks are related to the consumer unit or just a random persistent stain?

Thanks so much for any advice anyone can offer!

I very much doubt the consumer unit is causing that.

Original cables buried in the plaster above? Looks like an old property.

Thank you for that, it’s reassured us!

Honestly I’m not entirely sure. It is an old property yes, built around 1910. We were just concerned some of the wiring might be deteriorating but we’ve had no issues with any of the electrics?

Is this consumer unit quite typical? It looks very old to us but we have no idea how old it actually is.

Probably from the 90s.

Do you know if they’re typically still safe at that age?

Your's has a couple is issues, the mcb is not compatible and a blank module is required. It doesn't meet current standards but that doesn't imply it is dangerous. Does the RCD trip when you press the button.
