BAS, you are getting pretty hot on all the if's and but's these days. I remember when you were writing long articles on how stupid, pointless and a waste of time part P would B. Now you are telling people to follow it?
Everyone here knows that a lot of things are a matter of opinion. It is often opinion whether a 6mm or 10mm cable is better. The difference in cost between these two is small, but not necessarily negligible. Especially if someone does not buy it by the roll and know where to get the best price.
A lot of posts are thinking about future-proofing an installation. A DIYer might think about what he will be adding in 10 years, but a developer doesn't give a damn. He will get the cheapest installation he can get away with, 6mm and all if it squeaks in within spec. So a professional sparks might well have in mind a budget install, not a super-duper DIYNOT one.
There is quite a difference between anticipating the absolutely best way of doing a job and the quickest and dirtiest you can get away with. Maybe the guys neighbour was very happy with her job. Maybe his will cost £300 by the time it is finished. If the neighbour's basic install was done competently, then almost certainly she will never have any problem with it.
