Hot Tub Running Cost Calculator

Wondering how a hot tub will impact your monthly electricity bill? It's the most common question potential buyers and current owners ask.

The answer depends on two key things: your local electricity price and how often you use it.

Use our simple calculator below to get an instant, personalised estimate of your daily, monthly, and annual running costs.

Your Hot Tub Running Cost Calculator

Get a quick and easy estimate of your electricity costs.

How to Use the Calculator

1. Find Your Electricity Price (per kWh): This is the single most important factor. Check your most recent electricity bill or contact your provider. We have included regional averages that can be selected as a guide, but yours may be different.
2. Estimate Your Usage: This is the active time you spend in the tub with the jets or pumps running and the likely time the product will need to be ran to get up to temperature. We have provided 3 pre selected scenarios to help you estimate usage from a daily user down to an occasional weekend hot tubber!

Disclaimer: This tool provides a close estimate based on your inputs. Keep reading to see what other factors can influence your final bill.

What Else Affects Your Hot Tub's Energy Use?

Your calculator gives a great baseline, but the actual cost is also determined by the tub's efficiency. A cheap, poorly-insulated tub will cost far more to run than a premium, energy-efficient model.

Here are the key factors to consider:

1. Insulation: This is the #1 factor. High-density, full-foam insulation (like that found in our models) traps heat, meaning the heater runs far less often.
2. The Cover: A poor-fitting, waterlogged, or thin cover is your biggest enemy. Heat escapes directly from the water's surface. A thick, thermal-locking cover is essential.
3. Ambient Air Temperature: Your hot tub will work harder (and use more electricity) to stay hot in the middle of winter than on a mild summer evening.
4. Set Water Temperature: Running your tub at 40°C (104°F) will cost significantly more than setting it to 38°C (100°F).
5. Pump & Heater Efficiency: Modern hot tubs use highly efficient circulation pumps and heaters that consume less power to do their job.

How to Reduce Your Hot Tub Running Costs

Owning a hot tub doesn't have to be expensive. Follow these expert tips to keep your electricity bill low:

1. Invest in a Thermal Cover: Make sure it's in good condition and fits snugly.
2. Reduce Temperatures when not needed: When you're away on holiday or not using the tub for a few days, use this setting to lower the temperature and reduce heating cycles.
3. Clean Filters Are More Efficient: Dirty filters make your pumps work harder, drawing more power.  Replace them regularly.
4. Lower the Temp by 1-2 Degrees: You likely won't feel the difference between 40°C and 39°C, but your wallet will.
5. Create a Windbreak: Placing your tub next to a fence or wall, or adding a privacy screen, can reduce heat loss from wind.
