The trouble with death from electrocution is that it can be so permanent.
Regulations differ from county to country. Issues may arise perhaps if you come to sell the property.
You will need the supply, fusing and cables, properly selected and configured for the power of the pump - you will need some kind of protection device and probably a pulll cord isolator on/off switch.
All this is guesswork - a professional installer will be able to advise you professionally - you should not worry about any extra cost of this - because you're worth it.
Good luck...
