It is very difficult to estimate as there are so many variants. The size of the pool, weather conditions, if the pool is covered and to what temperature the pool is heated are all contributing factors. As we supply only, we rely on our customers to give us feedback on this. They have told us the average cost is £100 per month when the pool is in use. Therefore, if the pool is in use all year round, that would still probably work out less than one family holiday abroad.
