When I turn the hot tap in the kitchen on lately it thumps loudly and shakes until the water flow stabilizes. What could be causing this and how do I go about fixing it?

If the water is getting scalding hot then you maybe getting air in the pipes. Most likely it is water hammer, the cure for this is to service the tap. In the tap you have what is called a jumper the the washer is fixed to, if you take that off and clean it up, put some silicon grease on the bit that goes into the tap body. Also could be from the mains stop valve, and it is the same remedy. Also see if the pipes are not fixed properly, they need to be fairly rigid, if not pop in a couple of brackets. All easy and cheap fixes

This happens at my work everyday. A plumber has looked at it 4 times, and each time has said that there is air in the pipes. How this happens is that someone must have turned off the main water during the night, or maybe there is a hole in a pipe that causes the air to get in. He told us there wasn't anything he could do since it was such a large building. There was no way of him knowing where the hole in the pipe could be...in the walls, etc. Or if it simply is the management turning off the water for some reason every night.

The washer in the tap is either loose or worn out. Turn the shut-off valve off under the sink, take out the valve and replace the washer...it is about 20 cents to replace. The reason why it eventually stops is because the valve heats up and expands.
PS: it is not air (unless you are on a well)... air cant get into a presurized system like the water system. Another thing is that it is on your hot tap. The water comes into your house and then into your hot water tank to be heated. When it goes into your tank, the tank will act as a "burper", allowing any air bubbles to burp out. Since you are having this problem on your hot tap, only at one sink, and every time you turn it on, it must be the washer flapping.

seems such as you have too extreme of water rigidity entering the abode. Any plumber has a gauge that would try the rigidity. If that is over 60 psi or so, you're able to evaluate setting up a rigidity regulator. as quickly as your rigidity is moderated, the thumping could pass away.

The only way that it could be air in the pipes is if you are on a well and the well ran dry (and you don't have a cistern) or for some reason your plumbing system has been opened so air could get in.
I would say that it is a bad washer...I have seen it before.

it's somehow gotten air in the main water line, or it could be that the water line itsself is not turned all the way on, ive been a plumber for 65 years now, been there done that, about ther only thing it can sooner or later do,is it may cause rust ot break loose in the water lines and you will get it in your tap water...........

Air in the pipes, run the water through to get rid of it

Air lock, it is possible to stabilise by running both taps for 4 or 5 mins, but not always succesful, if you do get a plumber in to bleed it don't get ripped off, it should be neither lengthy nor difficult. an hours work MAXIMUM.

Either air in the pipes or water pressure needs adjusting

It's called 'water hammer' and is caused by unsecured pipework , probably below the floor, solution is to fit pipe clips to unsupported pipe, almost certainly a 15mm/half inch mains supply pipe. Easy diy job.
**Disregard suggestions to 'bleed your radiators' they have nothing at all to do with your hot water tap pipework**
