When one of my customers enquired about an upgrade from TNS to PME they said they would gladly do it but it is chargeable work, they quoted him ÂŁ150 + vat

Sorry, typing error. tnp to pms, no err....tms to tsn, errm no, thats not right. It was ÂŁ150 anyway
They only PME a previously TN-S supply, when the lead sheath can no longer provide a suitably low resistance path back to the TX, normally because of corrosion. Other than that, it'll be TT systems that they are converting. Which was the original reason for the implementation of PME systems...
Not so. Round here in the villages a large proportion of houses have an overhead 2 wire supply and the vast majority have been converted to TN-C-S/PME. No problem getting a TT changed over - it just lightens the clients wallet by about ÂŁ150.
