The point I was trying to put across is that it is not that difficult to do a simple job like changing a consumer unit to a larger one if none of the variables inside the property have changed. I changed mine because I'm fitting a bigger kitchen later this year, and am moving away from a gas powered kitchen to electric. My intention is to have 2 direct feeds from the CU to the Hob and Oven and 2 ring circuits. One for high power appliances (Washing Machine, Dishwasher, Tumble Drier), and the other for low power appliances (Kettle, Convection Microwave, Fridge/Freezer), my reason for 2 rings is simple, in the past I have had washing machine, dishwasher, & microwave on timer whilst at work, I arrive back home on a few occasions to find nothing has been completed because the power tripped out, this doesn't take much to figure out that the power requirements are too much for the existing circuits as well as highlighting a potential hotspot in the home. I have not jumped to this idea by myself, my brother is an electrician of 11 years and have looked to him for guidance, like he looks to me and my Microsoft Certification when he has a problem with his PC.
Please don't tell me I have no idea of planning cabling routes, placement of objects or knowledge to complete the task in hand. In my job I design plans and flowcharts with complexity like nothing many of you have seen before, and if i'm unsure about anything in the slightest I go to the right person and find the correct information. Why don't you go and try using something like Microsoft Visio fluently and then you'll know what I'm talking about.
