2. Bog standard house wiring isn't that hard and of you buy a copy of the 17th Regs and the On Site Guide you can read the relevant sections on cable length/volt drop/floor area on a ring circuit etc. On the one hand we have people moaning that domestic installation work is boring and all the same, then you need a degree to understand it all?! Slightly paradoxical.
never-ever-ever moaned about any electrical work being boring... :|
Not all DIYers want to wire the house in bell wire. Some take their time and do a decent job of it. We have all seen the work of some of these so called 'electricians' on here!
ALL aspects of building work are easy... if you know what you are doing...
Experience doesn't come from reading books though..
it is from experience working in any trade or proffession...
Lack of experience is seen day in day out with keen DIY's missing obvious points early on in a building project causing problems later...
Consider the example of the shower room heating thread the other day..

No doubt it was easy to fit out the shower room at first..
probably saved some money along the way..
it is safe...
BUT the design does NOT do what the customer wants!!!!
and is now going to probably cost more than would have been necessary with a better design!
It is easy to stick a light on a wall or ceiling....
But I lose track of how many times I come across jobs where consideration of where you are going to switch it from was completely missed out of the equation! :_| :_|
It may on occasion be better to run some low voltage control via contactors or relays to meet the customers requirements..
rather than just running from fuse box to switch to light!
I cannot think of any quotes I have done for any significant work where I haven't asked the customer what I consider to be a basic question..
But the customer goes.. "ohhh I never thought of that!"
DIY wiring is possible, is legal and can be done safely compliant with all regulations..
But a professional evaluation of a situation can often save time, money and/or provide a better overall solution to a problem..
Especially with something such as full rewire/new build!
Another point for consideration:-
If the DIY person has another full time day job there can be complications keeping up with other trades timescales...
i.e. you cannot put your cables in till some wall and ceiling stud work is in place...
But if you are too slow the plasterers are boarding it all up before you have run your cables...
OR you are paying other trades to hang around or make second visits to allow you to get more cable from the wholesalers
cuz you ran out or miss estimated some materials or how long you needed to fix it.....
Again it is NOT hard to do.. but I assume you agree those with more years of experience are more able to do these planning organising, scheduling of work materials, prioritising tasks to compliment other trades as second nature better than the novice DIY electrician.
These are the bits that the books cannot teach you!
A professional acting as mentor, guide project manager can ease a lot of headaches...
(you see it time and again on these DIY home improvement programs... :_| )
If time is no problem and other trades can work around your timescales
I don't doubt it would be a very fulfilling and rewarding project..
BUT either way you do need to fully assess and plan the project correctly!
