Hierarchy of tradesmen on a building site!

[LittenTree]

Which could, crudely translate as 'who earns most/ who earns least'?

I am thinking:
electricians
plumbers
plasterers
carpenters
bricklayers
tilers
etc

I foolishly thought they were much of a muchness but I gather not. I have also discovered that they require quite different entry requirements.

Anyone know either the 'hierarchy' or the likely entry requirements ?

TIA

Payscale info can be found here

Plumbers earn a lot but have high costs due to corgi registration.

Electriciens can take further qualifications and can really specialise to raise earnings.

You can find out about entry to these careers here at direct gov or here at connexions

There is a simple answer as to who earns the most. It's the gaffer!

Anyone who has the skillset and has a bit of 'something' about him, who can manage (himself mostly, but also others) will do well.
