The specification will show the type of supply required, generally, this is 32 Amps for most Hot Tubs. A dedicated 32 Amp electrical supply will usually be required.
Any circuit involving water should be protected from water ingress and have an electrical trip in case of any shorts or over current for your safety. This would need installing by a qualified electrician.
Hire tubs often come with a 13 Amp requirement and can be run from a domestic plug. As with a full install, the electrics should be protected from water ingress and have an electrical trip.
At the time of installation if a suitable supply is not available we will not be able to connect your Hot Tub to the supply until such time as the issue is remedied.
If there are any doubts please give us or a qualified electrician a call for advice.
