Feed to shed/garage 2m from house. Can I use an overhead feed?

I am re-wiring my house during it's current renovation.I'm not qualified or registered. But regarding the inside light and socket rings I'm confident that it's all done correctly. What I do not have any experience in is feeding external buildings. The existing wiring that feeds my shed does so by a 2.5mm spur from an existing ring. None of the electrics were certified before I purchased the house. This cable/wire exits the house at around 2m from ground level from a small 'utility' room built on the back of the house. The wire traverses a 2-3m horizontal gap to the shed where it enters again at about 2m from ground height and feeds a double socket and light inside. There is no other protection other than the grey outer cover. Basically a live mains cable, 2m up in the air swaying in the wind. BONZA!? I'm certain this is not the correct approach. What I do not know is, what is the correct approach? What I do know is the shed is on a 8" concrete 'foundation' that runs all the way to the house. I'm fairly certain I have space for a RCB in the CU for this feed if (as i expect) it's necessary. My garage feed, which is also overhead is 2.6m from ground level. However this runs inside a galvanised tube about 1" in diameter. This is certainly more secure - but is this ok to re-use? The tube is basically built into the brickwork of both the house and garage. Advice would be much appreciated. House earth is TN-S. Shed load will be max 2kw like a heat gun. Garage may have compressor, welder and more - will have its own CU. Everything newly installed has rcd protection.
