Building regs key points

[diditrain]

Has anyone created a compacted version of the key points from the building regulations, that are likely to get asked during an assessment?
If so could you show me where it is please.

 

[Phoenix]

Don't worry, skim through the book a couple of times thinking mainly about how it affects us, eg wall chasing, drilling / notching joists, extractor fans etc. You can refer to it anyway!!!

 

[diditrain]

Which book, the electricians guide to the building regs?

 

[Phoenix]

Yep, that's the one!

 

[diditrain]

I better go buy it then

 

[Phoenix]

When is your assessment? This is one of a few books you'll need in your 'library'

 

[diditrain]

Thursday

 

[Phoenix]

Well, get your check list out & get buying! You may have left it a LITTLE late!

I wrote this before the update of the BR that may be of use, not specifically the questions asked just a ready reference of key points. Not much about Part P because we all already know that!
I do not claim that it covers everything or is currently up to date but there should be few changes apart from the notification bits, afaik.

Thanks for that list, a good starter for ten! Pretty much the same now I think, but my assessor was also interested in WHERE extractor fans need to be (eg utilities, en suite, etc where no opening windows), apparantly prefer smokes to be on light circuit now rather than RCBO as a fault is more likely to be noticed by users, energy saving can now use low energy luminaires in standard fittings rather than dedicated fittings. In short. all the info is in the book and on here, you can refer to the book in the assessment, so if you know where to find stuff you should be fine. Good luck!

Elecsa assessors like to see the Electricians Guide to the Buildings Regs, but their welcome pack didn't mention it when I joined. Its a useful book to have in your library.

 

[diditrain]

Agree with you Murdoch, but it does give a list of relevant building regs, so i should of realised and got my act together sooner.

Procrastination is the thief of my time

 

[Phoenix]

Well, diditrain, how did it go?

 

[diditrain]

Yeah it went well. Passed with an A

 

[Phoenix]

Well done, fella.
