They rang me to ask about different tarrifs etc and at the end they said the meter was available also one of those multi sockets that allows you to turn of several thing at once instead of leaving them on standby. It took them about a month to arrive but they were free of charge.
On reflection it may have been because I asked about anything they could offer to help with disabled people, "my wife".
They also said it was a special offer at the time! ould have been a push to either retain existing or get new customers.
I think I have seen an advert on TV for similar but I am not sure if it was B/Gas.
Nothing compared to a tumble dryer. Even a washing machine is nothing compared to a tumble dryer. Anything with a fan and a heating element is expensive. A PC has a circuit that needs cooling with 12 cm or most often 8cm fans.
