Hot Tub Power Installation

Hot tubs run on electricity. So, one of the things you will need to consider before you decide to purchase a hot tub is your power supply requirements and installation. Before you install your hot tub you will need to get a qualified electrician to assess the power supply required for your hot tub. 


Before you purchase a hot tub you need to consider these two factors:

The existing power supply in your home may dictate the power supply you are capable of running outside/ where the power supply can be run to (ie. where your hot tub can go)  

Knowing what power supply you can get can help narrow down the buying options.


Why is it important to get your hot tub power supply right?

Getting your hot tub power supply right is important for two reasons:

  • To ensure it has enough electricity to power the hot tub
  • As a safety measure 

Hot tubs require different power supplies depending on how much power they draw. The pumps, heater, lights and all the other electrical components require power. If the right AMP of electrical supply is not installed then you the hot tub may attempt to draw too much power from the electrical line. This will cause an overload circuit. If this happens then the power will trip. And your hot tub will turn off. 

Secondly, ensuring that you install the correct electrical supply is a safety measure. If you install a much higher supply than you need then it will never trip. Tripping occurs as a result of, or to indicate a fault. Therefore you need to install the correct power supply to ensure, that if necessary, the hot tub is capable of tripping the power. 

What hot tub power supply do I need?

What hot tub power supply you need will entirely depend on what hot tub you are getting. So it’s something you will need to discuss with your supplier. But, if you have any limitations in your electrical supply, you should let them know to help narrow down your options. 

There are a couple of standard hot tub power supplies.

The standard plug and play range either use 13AMP or 16AMP supplies. The 13AMP models often have plugs. These can be plugged directly into a standard household socket. Some of the higher end plug and play ranges operate at a slightly higher wattage and will require a 16AMP power supply.

Most hot tubs require a 32AMP supply. And some will require 40AMP.


Our experienced electricians can install a galvanised steel armour cable, which has a protective conduit around the wires, to ensure that it won’t get damaged or degrade outside. Call us on 01484 712856 to find out how we can assist you with your hot tub installation.
