[QUOTE="betty swollocks, post: 27379, member: 105"] buy a decent clamp meter, turn everything on in house and see the reading you get quite simple calculation to find what 'everything' is costing per hour/unit had two or three jobs in past in flats and in flats/houses above or to the side of shops, all of them had the majority of the shops leccy running from the residents cu insulation testing should show a faulty circuit to earth immediately a clamp meter would tell you what power they are using, you could turn mcbs off in turn while watching the display, if there is a problem circuit you should be able to identify and narrow your search i like faults like this so let us know what happens [/QUOTE]
