16th or 17th

An extension that has been self build and has by the very name taken some time, is just about finished. The board was changed at the onset back in 2006 with the addition circuits added as and when relative parts of the extension were ready. The board was split load but not a dual split as per the 17th. As the work began back in 2006 when the planning permission was issued is this consumer unit Ok

As i understand it, by the book, we were given six months to complete any works that were designed to the 16th.

But as we are out of that period, the CU may have to be changed.

Best thing to do is talk to your electrician and see what he says as its his name on the cert.

Personally i dont see it as a problem as i would fill the cert stating design etc was to 16th.

Either that or just replace the MCB's of the circuits that were worked on with RCBO's, then that will comply as long as everything else is up to date, earthing etc, which it should be seeing as your cu was changed a couple of years ago.
