Delivery & Installation Requirements

Please check and double check the access route. If you have any concerns or considerations please don’t hesitate to call us. We have vast experience in hot tub installation however good preparation is always a good idea. 

Evolution 8B Electrical Requirements

These models require a 32-amp supply on 6mm SWA cable with RCD protection (cable sizes may be different depending on the length of cable run between the consumer unit and commando socket). A commando socket with local isolation is required between 1.5 meters and 3 metres of the spa, complete with ‘male’ plug and 8 metres of SY flex with UV protection or supply with flexible conduit). The flex is hard-wired to the spa by our engineers, then simply plugged in to complete.

A 32AMP dedicated electrical installation will typically cost around £300-£350 and typically take approximately two hours to complete.

* The commando socket supply DOES NOT require your electrician present on installation. However, a 32 amp ‘hard-wired’ supply WILL REQUIRE YOUR ELECTRICIAN PRESENT ON INSTALLATION to complete the wiring connection.

A new RCD circuit breaker must be used for your spa installation. Do not use an existing breaker, as its condition is unknown. The spa must be connected to a dedicated RCD breaker that is not shared with any other equipment. Do not use an extension or plug type cords of any kind.

The hot tub does not come with a plug and SY flex so please make sure this is supplied by your electrician.
