To be fair the dryer thing does depend on the type, a standard condensing dryer I wouldn’t have one in my house under any circumstances esp now the heat pump ones are much cheaper to buy and run and don’t burn your house down. We’ve had ours years now it cost £400 and it’s paid for itself more than once over.
Past 30 days ours has used 14kwh and it’s used every day unfortunately the runtime time includes time switched on not running so 600 hours and 14kwh doesn’t really help but it is used every day and we pay 14p/kwh on Agile
