Am unsure to the following: the very nice plumber chap who gives me loads of jobs quite often calls and says that there is another boiler that needs bonding and by-the-way the stat needs moving or changing to something more modern sort of thing, none of which is ever a problem technically. So the question is... is this a case for the minor installation certificate or can the whole thing just be done, check the Zs on the boiler circuit, the house main bonds and walk away...???
