Between January and July this year British Gas engineers discovered over 25,000 dangerously unsafe electrical devices during their home visits. 

 

That’s about one in every 20 homes where they have carried out an electricity and gas safety check when installing meters. The most common faults involved old ovens and boilers. 

 

British Gas says that its engineers regularly visit customers who haven't had their electrical wiring or gas appliances checked for 10 to 20 years. In some cases, the unsafe appliances they discover could have a devastating effect on health and safety.
