I think everybody should have a go at doing any kind of work to their house. I am an electrician but I have also installed my own central heating system (apart from the boiler as a corgi registered plumber has to connect the gas),. I also recently installed my new kitchen and re-decorated the dining room. The next big job, which I am saving up for, is a new bathroom. The only thing I have found I am no good at is plastering (ends up looking like artex when i do it). I have saved a small fortune by doing the work myself. The money I have saved doing this work myself will then go towards the 'toys' for the living room, but you will have to wait for my thread called 'my not so modest cinema/living room setup' to see what I install (subject to what the GF allows me to do)
So, go on have a go. you will save a fortune by not using tradesmen to do your dirty work and I should know, I am one.
By the way, nice work there monkeh.
