Frequently Asked Questions
Do I need an electrician to wire a hot tub?
Yes — hot tubs require a dedicated circuit with an RCD-protected supply, installed by a qualified electrician. Most hot tubs need a 32A or 40A supply on a dedicated circuit from your consumer unit. This is notifiable work under Part P Building Regulations.
How much does hot tub wiring cost?
Hot tub electrical installation typically costs £400–£1,200 plus VAT depending on the distance from your consumer unit, whether you need a consumer unit upgrade, and the amp rating of your hot tub. We provide free site surveys and quotes.
What size cable do I need for a hot tub?
Most domestic hot tubs require 6mm² or 10mm² cable on a 32A or 40A MCB/RCBO, depending on the hot tub's power rating and cable run length. We calculate the exact cable size based on your specific installation to ensure BS 7671 compliance.
Can my existing consumer unit handle a hot tub?
It depends on your current load and spare capacity. During our free survey, we'll check your consumer unit and advise if an upgrade is needed. Many older units lack the spare ways or RCD protection required for a hot tub circuit.
