New build properties not installed to regs at the time of construction

Newfutile

I have come across many new builds where they would not meet the requirements at the time of installation.

We have brought this up with the developer / installer,they have mostly quoted best practise guide 4 saying that it's only a C3.

The way I read bpg4 is that it's for coding when the instalation was to a previous edition of the regulations.

What recourse is there in this situation?

    Where does Part P stand in relation to this? The latest versionI can find is 2013 which refers to BS7671:2008 incorporating Amendment No 1:2011.

    See also here:  ESQCR (The Electricity Safety, Quality and Continuity Regulations) and BS7671 

    Most of the time, the discussion concludes with 'use the latest version of the standard' as there are few cases where the new version is 'less safe' than the previous version.

    In practical terms, there are some 'conformity' issues that might conflict, but a reasonable person would normally conclude that a later approach ought to be used. An earlier version of the standard might not permit current products to be considered to be safe in all situations - for example, no EV in 2011 !

    (And on EV, if you're working one something that comes under Part S, well isn't there a conflict between AD-S and AD-P if the latest standard is not accepted for AD-P?)

    I am sure people had no problem plugging in milk floats long before the IET's ever-changing rules on EV chargers. Or long before the IET, for that matter.

    No, they wouldn't ... for a number of reasons including the fact that this also preceded ESQCR ...

    In addition, it's not simply the 'IET' that determine what's in BS 7671 ... it's a British Standard, developed with consensus of a wide-ranging committee representatives from the industry in the UK just like any other.

    I am not sure milk floats used O-PEN detection by voltage deviation

    Assuming the supply was PME ... the DTI guidance on ESQCR hadn't been published at that time ... it didn't arrive until 2002.

    Also, the earth electrode resistances used for PME electrodes used to be 10 Ω, whereas today they are 20 Ω, and I understand there are discussions as to whether to go to 40 Ω.

    And finally, in the cases where milk floats were charged outdoors, a much smaller population was exposed to any PME risk, than are exposed to contact with EV today ... never mind when every vehicle is electric !

    Such glib "looks to the past" without context and a complete consideration as to what's changed between the "glorious past" and the present, aren't really helpful at all.
