Raymond Edgell and his wife Sandra decided to get a smart meter fitted last August.
Their old gas and electricity meters in their home in Harefield, near Uxbridge, were in a cupboard under the stairs. And the couple — who are both in their 70s — were increasingly finding it a pain to take regular meter readings.
The new 'smart' device promised to send readings to their supplier, Scottish Power, automatically and ensure their bills would always be accurate.
