Make sure that your hot tub will be placed on flat, stable ground. If placing your hot tub on the decking, make sure it can withhold the weight of the tub. You may need to put it on slabs, bricks, or hot tub pads. The grass is not a good option as it will be displaced by rainwater and water from the hot tub.
Your hot tub will need to be drained and refilled at least once a year, so it will need to be accessed for maintenance and cleaning. Make sure it’s in an accessible space that can drain large quantities of water well.
You will need to decide how you are going to power your hot tub, you can plug it into an outside wall outlet in which you’ll need an electrician to install a waterproof socket protected by a circuit breaker or residual current device. The other way to connect your hot tub to the power supply is via the mains.
You need to ensure that your hot tub complies with Part P of the Buildings Regulations. You are responsible for the safety of electrical work in your house and could be prosecuted if work you have done yourself is deemed unsafe. Hot tubs and spas requiring over 13amps will need a dedicated supply. It is best to hire a qualified electrician.
Getting your hot tub to the desired location may require the use of a crane to lift it over the house, should there be no alternative way to access the garden.
