Replacing Consumer Unit When Mains Wires go Straight into it

How do you replace the consumer unit when the wires from the mains come straight into it? Mine needs replacing but I can't understand how to connect it to the mains.

Step one contact council pay your fee as no point in contacting DNO if you find the council will not let you do the work anyway.

Next contact DNO there are two options either they draw fuse you do the work and then they reconnect, or they fit an isolator, or in fact you can fit an isolator then get DNO to connect to it.

Next job is fit the new consumer unit, not only will you need to actually need to connect everything up but you will also need to test all circuits, you will have arranged with the LABC as to what they will allow you to do and what must be done by their appointed agent.

One thing to remember it will likely cost more to DIY than to get a scheme member to do the job for you, however if your really want to do the job then the biggest hurdle is to get the council to let you.

If you do not know how to connect cables to a new CU, you must not do this work. You are breaking the law.

As said (But not so harsh) to ask such a question implies you do not have the knowledge to carry out the job safely. Best get an electrician to do the job for you.
