Part P is the latest addition to the building regs.
Building regs tend to be assigned a letter ( part P ) based on their time of initial assignment from what I can gather.
So what will Part Q be?
This is purely speculative, not based on fact and fictitious but possibly incorporating:
Part Q ( Fixtures to dwellings and the safety thereof ) section 1 ( ODPM directive ). No one shall fit a picture frame to a wall in a dwelling that incorporates a glass protective covering of the picture be it reflecting or non-reflecting glass. All protective coverings must be either toughened glass or made of plastic complying with BS303030. If you change the picture in a said frame you must also upgrade the glass protective covering or the frame to one approved or use a person registered with a Competent Person self registering competence body. Changing the picture in the frame and not using a Competent Person means that you need to apply for building regs approval. Pictures fitted above head height ( 2.5 metres to ensure the tallest is protected ) must be securely fixed to the wall using fasteners that comply with BS10101010. Also, pictures of a particularly attractive nature - where a person may require close viewing - must use a frame that cannot introduce wood splinters into their flesh as they view - in brief the frame must comply with BS20202020. Building regs notification to change a picture in a fixed domestic picture frame OR the frame itself will only cost £ 58.00 unless done by a COMPETENT PERSON.
This is a discussion igniter only - but do you see where I'm heading.
The regulators will no doubt be working to regulate similar as they read this post.
Maybe I should have kept it to myself - unless of course you are a picture framer.
What other Part Q's could there be?
Sceptical - what me - no!!
