You have a lot to learn young Jedi :beatnik2:, listen to your uncle Spin, and uncle Dilib, lol, they are correct, if you actually listened to what they are saying, and not what you "think" they are saying, then you might just learn something.

I am all for learning. That is how I got to where I am. But not by listening to day 1 of 'commmon myths about the electrical game'
 
The only "myths" so far is that BS7671 is the be all and end all, you might consider reading the very beginning of the current regs to gain a better understanding.

if you are only doing domestic small jobs then of course it makes sense to work to current regs, Spin already gave you an example of a large project that spans multiple versions of BS7671, in fact BS7671 itself actually states any design started after new regs (the January date) comes into force must be to the new current regs, the keywords "designed after".

Also BS7671 states by following the standards as laid down in BS7671 then conformity to the relevant parts of the EAWR legislation is "likely" to be achieved, (only likely?) lol.
 
Implementation Dates:
1st January 2015 - The Third amendment to BS 7671:2008, The IET Wiring Regulations, became effective on this date. Following this, contractors have a six month transition period to get up to speed with the changes and can design, install and certify to either the new or previous standard.
1st July 2015 – From this date it is a requirement that all electrical installations designed and periodically inspected comply with the updated regulations. Contractors will be expected to hold a copy of BS 7671:2008, incorporating Amendment 3, for any assessment visit taking place after this date.
1st January 2016 – Regulation 421.1.201 (PROTECTION AGAINST FIRE CAUSED BY ELECTRICAL EQUIPMENT) comes into full effect.

Take care when reading and interpreting formal documents ... 1st Jan - 30th Jun Contractors 'can design, install and certify to either the new OR previous standard'; from 1st Jul 'it is a requirement that all electrical installations designed and periodically inspected comply with the updated regulations.' It is interesting to note that installation is excluded from the second list.


For those with greater insight, if something that is periodically inspected must comply with the updated regulations, does this mean retrospective application or is there likely to be an equivalent to the 'Note by the Health and Safety Executive' which is on P12 of Amendment No: 1? This note states that 'Installations which conform to the standards laid down in BS 7671:2008 are regarded by HSE as likely to achieve conformity with the relevant parts of the Electricity at Work Regulations 1989.' It goes on to describe how existing installations designed and installed to earlier editions will not fail to conform to the relevant parts of the EaWR 1989.

spark 68 ... you got there before me! However, do note that both standards can be used from 1 Jan 2015 up until 30 Jun 2015.
 
One of the problems the IET has, is that any new requirements suggest that earlier versions are unsafe.
Due to this they issue a disclaimer which they hope will prevent litigation for issuing poor or even dangerous advice in earlier versions.

No I cannot at this time agree that installations must be constructed to the new requirements after the 1st of July, without first seeing the final draft of the new requirements.
From what has been posted, it appears that if the design is to the current requirements then even if construction begins after the new requirements come into force, it can still be constructed to the requirements in force at the time of design.

My mistake lol, the June date it is lol by page 4

No doubt the way the regs are written there will be a contradiction somewhere.

Edit: on page 7 (BGB) it says the 1st AMD was issued on 1st of July 2011 and intended to come into effect on 1st of Jan 2012, installations designed after 31st Dec 2011 are to comply with BS761:2008 amd1

Joined up thinking by the IET as ever lol
 
Up untill this latest amendment, it has always been the situation that an installation designed to one edition or amendment can be constructed to those requirements after the introduction and the coming into force of any new edition or amendment.
Yes there have been many concerns raised due to the Olympic site being constructed to the 16th edition even after 17th edition amd1 came into force.
However it was such a large and expensive project, that redesigning it to newer requirements would probably have entailed new tendering and could possibly have delayed the project.
Costs would certainly have increased, most likely by a substantial amount.
However, I doubt that it is feasible to introduce a requirement for an installation to be re-designed, every time the requirements are updated.
