Hot tub

What it costs to run, and where that number comes from.

At the current price cap rate of 26.11p per kWh, a typical hot tub costs about £3.13 per day, which is £1140.48 a year on the usage below.

This one cycles. It switches on and off rather than running flat out, so multiplying its plate rating by the hours it is switched on overstates the cost, often by a factor of two or three. The figures here assume it draws full power for the time shown, which makes them a ceiling rather than a bill.

Where that number comes from

Across the range of powers for this appliance class, one day costs between £2.35 and £9.40. Your own figure is on the rating plate, usually on the back or inside the door, and it is the only one that is true for you.

The single most variable item here. Insulation, cover, ambient temperature and how often you use it matter more than the rated power.

What does it cost to run?

Change any of these. The rate is the current price cap average, but yours is on your bill and is the one that matters.
