The reliable way to hire a tradesperson

Could someone point me in the right direction as to who could help with this? I have an external cable entry point on an outside wall that needs tidying up. Sky TV is working normally, but there appears to be an old NTL/Virgin cable and some exposed wiring outside. I'm looking for someone to identify any redundant cables, tidy the area, fit a weatherproof cover if required, and seal the wall entry point. There is no electrical fault and no actual electrical work required. Would this be within the remit of a handyman, or is there a more suitable trade I should contact?

I currently have a chimney breast that is closed and plastered. I want to open it up and insert an electric stove so that it looks like a real log burner. Do I need to go through building control or planning to do this

Hi not sure whether to replace cast iron guttering with uPVC? Or replace like for like. . The problem is the cast iron half round brackets are wrecked and looks like they are concreted in. How the heck can they come out? Some will need to be replaced. If it was replaced with uPVC ones does a soffit board need to go up if nothing there. Thanks in advance.
