looking at having to re-wire my ex-wifes house to save on cash. It
definitely needs a new consumer unit - the existing one being a metal
box with some old bakerlite type switches and well you get the idea.
Also the wiring to the light fittings and sockets is starting to fall
apart. There are woefully inadequate numbers of sockets so I need to
add to these. I have multiple questions and would really appreciate
any help.
1) should I just save up and get an electrician in?
2) should I do the donkey work myself - I am reasonably competant at
stuff - and get an electrician in to do the consumer unit?
3) I presume that I will be having to cut out channels in wall to add
new sockets - is there a good book on the planning of a rewire with
good practical advice
4) Should I rent or buy and angle grinder to do the channelling?

etc etc
Clearly I have not done this before but as the house really belongs to
me I am not averse to gtting stuck in and sorting th#e jovb myself -
if it isnt going to take to long.

Any advice is welcome.
