Electric Supply - What Do I Need?

WHAT ELECTRICITY SUPPLY DO I NEED FOR MY HOT TUB?

The type of electricity you have is one of the most important things when purchasing a hot tub, Our hot tub specialists are always on hand to give you the right advice when it comes to the type of electrical supply you will need. 

DO YOU DO THE ELECTRICS FOR US?

We would not carry out your electrical works, this needs to be completed by a certified Electrician who can put an electrical socket outside your home or make adjustments to the electrical supply inside your house, and supply a Part P Certificate.

If you do not comply with the Building Regulations, this is deemed a criminal offence.

I WANT A 13A PLUG & PLAY HOT TUB

If you choose a 13Amp Plug and Play hot tub, the running costs will be lower than if you chose a 32Amp tub. 

A 13Amp hot tub will just plug into an everyday 3-pin power socket like you would use to plug your kettle into, but you will need to get a certified Electrician to install an outdoor waterproof plug socket with RCD protection. 

This is a life-saving device to prevent electric shock should you touch something live. 

I WANT A 32A HOT TUB

If you choose a 32Amp hard wired hot tub, this kind of hot tub is more powerful, therefore resulting in a different type of outdoor socket.

The hot tub can not share a supply with any other applications and must be hard-wired into its own fused spur, back to the consumer unit. A mains circuit breaker (MCB) will be required and this will need to cover 32Amps, plus an additional 25% as there will be an initial surge in current when the pumps are activated.


An IP65 Rotary Isolator Switch will be required, this should always be installed by a certified Electrician. This is a form of trip switch, should maintenance works be needed or an emergency occurs.


A 6mm² 3-core SWA cable will be required, and the switch should be at least 2m away from the hot tub. One of the most important things that your Electrician will need to do is make sure that he has left sufficient spare cable connected to the isolation switch to go to the far side of the hot tub. This is the only bit of electrical works that our Engineers are qualified to complete.
