Copper pipe corrosion

[stev]

Dripping tap on bath, decided to look at just replacing the tap. This is what I found removing the panel (been 3 years since I moved in). I'm guessing this is not good, but what should I do? (Hot pipe is the one on the right)

Clean the pipe with wire wool so you can see the condition of the copper. It may ,or may not need replacing. The tap connector above would have been leaking to cause this.

Thanks, I've done that and most comes away here is what I'm left with (how to tell if it needs replacing?)

Unless you can get back to bright ,shiny,smooth copper,I would replace those pipe sections , your pics appear to show more than superficial surface degradation.

Is there any reason why the hot water pipe is larger than the cold?

Usually cos the hot water is gravity fed and cold is mains fed

So, if I wanted to replace the corroded section, would that have to be a plumber's job? Or could I do it with basic DIY?

It's not rocket science to join pieces of pipework and fittings together ,but if you don't know anything about plumbing you need to do some research.
