My mother has just had a light fitting replaced out of necessity. The electrician who did the work gave her a "Minor Works Certificate" to cover the work. On it he drew attention to the fact that the wiring was over 40 years old and that the insulation resistance test on the lighting circuit concerned was only 1.2 Mega Ohms (I've read on here a figure of 2 Mega Ohms quoted as the minimum). He recommended that a rewire was necessary and should be carried out in the "near future". Now, I'm pretty happy that a rewire is a good idea (Victorian house and we know it is at least a 1960's electrical installation) but can anyone tell me, based on this resistance figure, is this urgent (ie before Christmas) or can this wait until the New Year?
Thank you in advance
