With ongoing research & reviewing, we are continuously developing our products and technology to be more energy-efficient and help reduce hot tub running costs as much as we can. As standard, Lay-Z-Spa hot tubs come with a range of energy-saving features that you won't find on other inflatable hot tubs and our blog is a great source of advice for using your Lay-Z-Spa and saving on your hot tub running costs

Lay-Z-Spa Running Costs

Cost-Effective Lay‑Z‑Spa Features


Our premium reinforced material is used on all our hot tubs and offers strength and better insulation

Power-Saving Timer

To avoid unnecessary use of energy, the timer can pre-program the heating times for up to 48 hours

Freeze Shield™

Automatically activates when temperatures drop below 6°C so you don't need a constant heat source in winter

Rapid Heating System

Turns off when set temperature is reached and only turns back on when the water drops a few degrees

Running Cost Saving Tips

  • Position your Lay-Z-Spa in a sheltered or covered area to prevent wind chill

  • Fill up with water from the hot tap with a few inches of cold in the bottom first

  • Keep your inflated lid and cover on when heating up and when not in use

  • Use a floor mat under your Lay-Z-Spa to prevent heat from escaping through the base

  • If used often, it is more cost-effective to keep the heater set to one temperature

  • When not used very often, turn the heat right down or off

  • We recommended shopping around energy providers to find the best deal
Lay-Z-Spa Weekly Running Costs

Weekly Running Costs

We estimate it costs around £7 - £10 a week* to run a Lay-Z-Spa based on average usage**. We are continually developing our hot tubs to be as cost-efficient as possible. For example, every Lay-Z-Spa from 2017 onwards includes the Power Saving Timer and all models from 2021 includes Freeze Shield™.

The Lay-Z-Spa pump heater unit is thermostatically regulated, allowing it to intelligently heat the hot tub to save on running costs, much like a central heating system. The heater will heat the water to your desired temperature and then switch off. It will then switch back on again once it falls a few degrees below this.

Our Lay-Z-Spas also come with a top cover and an inflatable inner disc to provide maximum insulation. We have a thick Lay-Z-Spa Floor Protector available as an accessory which provides added protection and insulation.

*Figures are based on the Vegas AirJet model used 3 times a week in average UK summer temperatures. Usage: approx 25 mins with 20 mins of Lay-Z-Spa massage function per use including a 5 min interval. Wind-block and cover utilised. (update 01/04/22: we are aware these figures are out-of-date and currently conducting extensive tests to update the information asap)

**This is based on feedback we have had from our customers. Please note this is ONLY an estimate and does not take into consideration specifics such as electricity supplier, increase in frequency of usage and outside ambient air temperature. E.g. a lower than average air temperature can cause increased electricity usage in order to maintain high water temperatures.

Energy Efficiency

According to an independent study of comparable products by comparable brands, Lay-Z-Spa is the most energy-efficient inflatable hot tub brand and you could save up to £620 a year.

Results from the independent test are:

1. Lay-Z-Spa pump heats the water to 40 degrees 10% faster than competitors pump.
2. Lay-Z-Spa pump uses significantly less energy to maintain the temperature when massage and heating are off (35% less)
3. Over a 3 year period competitor's hot tub would cost £620 more than Lay-Z-Spa in energy costs if using all year, or £310 if using for 6 months of the year.**
4. Lay-Z-Spa offers significantly better insulation than competitor's - when not heating, water temperature drops 18% faster in competitor's hot tub than Lay-Z-Spa.

Additionally, all our hot tubs come with an inflatable lid and DuraPlus™ cover creating extra insulation to keep the heat in your Lay‑Z‑Spa.

*Test & results have been performed by SGS laboratory. They are based on Lay-Z-Spa Cancun compared to a similar model from our competitor. Both hot tubs had the same volume of water, were tested with the lid & cover on, were set in a room under the same conditions.

**Based on energy use comparison of heater running constantly. Lay-Z-Spa average energy cost over 3 years using for 6 months per year = £883 Competitor’s Spa average energy cost over 3 years using for 6 months per year = £1,193 Unit Cost per KW = £0,16.
