Can I do my own Electrics?

In short the answer is yes.
In reality I'd say you're better off leaving it to the professionals, certain works are okay such as replacing a socket, but when you get up to installing new circuits, replacing fuse boards for consumer units then the work needs to be tested, certified and registered with building control under part p of the building regulations.


So unfortunately you can do any work you want and I say unfortunately because I've had to go and sort out DIY electrics gone wrong many times with simple things such as a light being installed wrongly.


The issue with electrics is work can be done badly and it will still work, but can be dangerous, It's a pretty good sign that if someone has to ask a question such as 'what cable should I use' then they shouldn't be doing that work.


On top of this most DIYers don't have a van full of tools, the test equipment needed, the insurance if it goes wrong or the experience if they encounter a situation and don't know what to do.


Many DIYer grossly underestimate how long a job will take and then take short cuts they think will be okay in order to finish the job. Also look at it this way an Electrician could do a job a lot quicker because of experience, so where it may take an electrician 1 hour a DIYer may take 2,3,4 hours. Wouldn't that time be better spent with the kids or on a day out with friends and save 'Work' for Mon-Fri.


Just remember that electricity is dangerous and about 11 people each year are killed from shocks, 7501 are injured from electric shocks and there are around 8074 fires caused by faulty electrics. It can be easy to take electricity for granted but as I always say 'just because it works, doesn't mean it's right'.


Be safe

Replacing an electrical fuseboard (Consumer Unit)

This blog post is all about having an electrical fuse board now known as a consumer unit replaced, what you should expect and how much it will cost.
Having an electrical fuseboard replaced is an involved job and not as simple as some may think, however for the trained professional it is a simple job. Replacing a fuse board with a consumer unit is generally a full days work, depending how big the property is, you can expect the work to take this long for a 3 bedroom house, but why?

An Electrical Installation Certificate
Firstly the electrical installation needs to be tested to make sure it's safe and that the new consumer unit won't trip when the circuits are connected it, if there is an electrical fault then this will need to be rectified before the fuse board is replaced. Once the installation has been inspected and tested the board can then be replaced, the tails (wires) feeding the board need to be replace and most times the earthing has to be upgraded too, sometimes the cables for the circuits are too short and then need to be extended which can add more time to the process.Once all this has been done a few more tests need to be done and an electrical installation certificate needs to be completed. 

If you have had or having a fuse board replaced for a consumer unit, and you have been told it will only take a couple of hours then it is possible the job will not be done properly!

How much will it cost?
I once quoted to change a fuse board, when I followed up with the customer to see if he wanted to go ahead with the work he said he'd found someone who could do it cheaper, When I asked how much I was given the reply £210, I was shocked (no pun intended) to hear this as the materials cost alone was was over £120 which meant he was only going to charge £90 for labour/overheads, I asked the customer if he'd asked the electrician (I use the term loosely) how long it would take - he was told it would be about a couple of hours! 
I strongly feel that the customer would not have had a good job done in this instance or been done properly, if you are quoted these sort of figures the I would definitely get a second opinion.

Prices as ever vary from electrician to electrician but I know prices can be around £350 - £650 Which includes Labour, materials, testing and certification. Again it depends the size of the electrical installation a studio flat will be less however a five bed house will be more.
