Hard water is found in regions that have a chalk and limestone geology; water picks up chalk carbonates as it passes through. It is not that London itself is built on chalk and limestone, but the area to the west where it comes from.

There are no health complications in drinking hard water. Nevertheless, hard water can lead to scale forming and may also affect the form of hot drinks, increase soap consumption, and decrease detergent efficiency. That is why your flat white might look a bit weird then.
