My original post was when is the dead line to have it done
. We seem to be getting off track.
If you are looking for good practice, sensible attitude toward electrical dangers and taking a responsible attitude toward any tenants livings at any property you own...
Then... As you say "you have done your research"...
and you have done significant wiring alterations 15 years ago..
When the applicable industry standard guidance, BS7671 wiring regulations, would have been 16th edition..
Which stated that all alterations should be inspected, tested and certified..
And you will be well aware that follow up periodic inspection and testing should be done every 5 years or change of occupancy for a rented dwelling.. (10 years for private dwellings)..
So its not rocket science for you to know when you last had a Satisfactory periodic inspection report for the property...
and when the "next inspection date" was written on that report...
And on the sticker/label attached on or near to the fuse box as per BS7671...
{ if for some obscure reason you have chosen to ignore industry good practice and don't actually have any current satisfactory periodic inspection report, (or EICR)..
Then you need it done A.S.A.P. }
The bottom line is that electricity can kill a healthy adult in less than half a second...
Plus cause serious fire damage to a property..
So its basically only the Landlords who ride around on horses with their cowboy boots firmly in the stirrups...
Who choose to neglect industry good practice...
