I would suggest that if you need to ask the question, then you are not
experienced enough to manage the work.

You can only save money if you are able to assemble the correct people at
the correct time, and even then, how do you know that the work quality and
the prices are as they should be?

If you are in the building trade, then you could do it, but if you don't
have that building knowledge, then it is a risk.

Don't assume that the builder is charging you OTT prices, the % profit is
not that big on the average extension job.

We're about to get some building work done involving the usual mix of
groundwork, brickwork, roofing, windows, plastering, plumbing, decorating
and electrics. I know that if I just get a builder to "do it" I'll be
paying
OTT for the various trades but am unsure about whether to manage it myself
and bring in the trades as needed.
Has anyone any experience of doing this or any advice?
