This is the most common question we are asked which generates over 48,100,100 results in Google with related searches being ‘hot tub running costs UK’, ‘true cost of running a hot tub’, ‘how much does it cost to run a hot tub a year’, and, ‘hot tub electric cost calculator UK’, however when we look at hot tub forums across England, Scotland, Ireland, and Wales the answers are somewhat misleading and totally inaccurate by some who we now describe within the wet leisure industry ‘hot tub manufacturer and retailer spammers’ – yes you do get them.

Unless you have a big bank balance or a large offshore wind farm here in Scotland, you are probably interested in getting an accurate estimate of the upfront and ongoing costs of hot tub ownership. The bad news is that the multitude of factors affecting hot tub energy costs can make this estimate hard to pin down. The good news, however, is that if you are planning on buying a brand-new hot tub, it is likely to be reasonably energy-efficient due to recent technological advances in hot tub insulation and heating equipment – that is if you have purchased a good energy efficient hot tub suitable for the Scottish climate.

So how much does it cost to run a hot tub here in the UK?

In terms of electricity costs, many modern hot tub manufacturers advertise their hot tubs at costing between £0.90 - £1.68 per day, with £51.10 per month at the high end based on the average cost range with the current 2021 UK electricity prices from with the UK being on average 14.40 p/kWH without any substantial nor accredited evidence.

As part of SPATECUK®, the UK’s fastest growing hot tub and swim spa training company, we have the complete knowledge and understanding that this information is far from the truth, as both Penguin Spas and SPATECUK® have witnessed hot tubs costing well over £80.00 to heat per month with some UK hot tub companies installing American, Canadian, European and Chinese Hot Tub advertising as insulated energy efficient hot tubs.

What are the true costs for Hot Tub with R10 insulation?

To show the difference R10 makes in the energy savings of a hot tub or spa, TUV SUD independently tested two types of heat insulated hot tubs; the standard insulated hot tub as described above and the R10 insulated hot tub from the UK's award-winning Sunbeach Spas and the results are staggering as we no longer need to invest or buy shares in a Scottish offshore wind farm.

As per the the independent technical report from world’s leading auditing and system certification company, TUV SUD show that hot tubs with R10 insulation will cost the UK consumer on average £14.10 per month or £169.19 per year saving you on average £428.26 per annum which will equate to £4,282.60 over the Ten-year shell structure warranty (without taking into consideration inflation).
