Sounds right to me...........

Plus turning your stop tap does nothing to alter the pressure

Have you investigated the main stopcock to the house. You could try closing it by half a turn to a turn and see if that makes any difference.

As mentioned above reducing the pressure might help. If this has just started it may be because that with the holiday season, there are fewer of your neighbours at home and you are getting the full pressure from the pipes. I'd hold off on any fancy solutions until after the summer hols are past, just to see if the problem goes away.

No, no and NO!!!

The stop tap does NOT affect the water pressure, it only affects the flow. Stop tap should always be fully open, otherwise you get the typical burst of water that turns to a trickle after a few seconds.

The stop tap could be open a tiny amount, but the static pressure inside will always equalise to the external pressure, even if the water can only get in through a pin sized hole.

The problem in OP is called "water hammer", it's definitely not helped by excessive water pressure, but the ONLY way to control water pressure is with a PRV (pressure reducing valve), these are cheap, they're easy to fit, they won't affect the amount or flow of water from taps or showers and they solve other issues such as leaking mixer taps where the pressure is too high for the tap.

I don't think I claimed it would reduce the Pressure.
