The question of legality in carrying out work on your own installation has been covered before in this NG. The consensus has been that you do not have to employ a CORGI fitter if the work that you carry out is done competently. I guess that in the ultimate circumstances a court would decide if you had been competent.
However does anyone know if the above is also true for the following specific circumstance:
I returned from holiday to find that my gas had been turned off by Transco after my neighbours had reported what they thought was a smell of gas (incorrectly I believe). The Transco people couldn't detect any gas leak but took the easy/safe/cover your orse option of switching off the supply and putting a notice through my door with the lowest of the three categories Concern for Safety ticked. The notice says: The gas equipment must not be used. It is an offence to continue to use an unsafe appliance or installation until tested by a CORGI registered installer.
So is it an offence or does the competency thing apply?
I hope that those of you who don't like your neighbours would not dream of using the above to land them with a CORGI McWhopper invoice :-)
