What moves the price
- Distance from the consumer unit — a hot tub far down the garden needs a longer armoured cable run
- Supply rating — 32A and 40A hot tubs need a heavier cable than a plug-in tub
- Trenching — burying the cable across a lawn or patio adds labour
- Isolator and RCD — an outdoor isolator and RCD protection are part of safe hot tub wiring
- Consumer unit capacity — a full board may need a spare way or upgrade
- Surface type — running cable under paving or decking takes longer than through soil
Electrical work prices in the UK are up 6% over five years (ONS Consumer Price Inflation, Services for maintenance and repair, to 2026 August). Five years ago a typical hot tub wiring would have cost about £430 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Place the hot tub as close to the house and consumer unit as is practical
- Dig the cable trench yourself if the electrician agrees, to cut the hot tub wiring cost
- Have the cable laid before paving or decking goes down
Before you book
- A new hot tub circuit is notifiable under Part P, so use a registered electrician
- Check the hot tub's required supply, such as 32A or 40A, before booking the electrician
- Ask where the isolator will go, as it should be within reach but out of reach of anyone in the hot tub
- Have the base ready and level before the hot tub is delivered and connected
