Basically I have some issues that need addressing to a domestic eletrical system. This is a three bed semi detached in Hertfordshire. It has 10 rooms including kitchen and bathroom. With 13 lights and 24 outlets in total. The consumer unit is a 7 way (all in use) MK sentury which was installed in the 90's. Over time further additional systems were added such as 2 showers (10mm wiring with fused connection units). But Just discovered without the proper new circuits being made. One was added to the kitchen power ring. The other on the upstairs power ring. Also the ground and first floor lighting (13 lights) is on the same 6A circuit. Which needs separating. The property is being renovated on a very tight budget and further additions are desired as well. These are the bathroom needs 2 led mirrors, shaving outlet and power to a bathroom TV. Then power taken from a new consumer unit to the garage. Which then powers nothing drastic like air compressors. Just some lights, outlets and a garage door opener. My question is will a proper part p electitrian to solve and add these aspects: New consumer unit Separate lighting circuit Two showers placed on own circuit Power taken to garage Bathroom additions Be more or less costly than having the home completely rewired with the additions. As I understand sometimes dealing with issues of current wiring can be more time consuming than re-doing it. Please ask any questions to help in answering. I am not an electrician but I will do my best.

Sounds pretty straightforward, I would get an EICR electrical inspection Condition Report done on it, which will highlight any issues on the wiring etc. as you are changing the consumer unit this would have to be done even if it was just a board change, so, you could negotiate a package with him/her once it's all been installed you require a Electrical Installation Certificate and it will require notification to Building Control which the registered ( part p ) electrician will do on your behalf.Then BC will send you a compliance certificate. Oh and the consumer unit needs to be metal with enough ways to accommodate existing and future circuits. Usually 20% spare to conform to current regulations.

Hi The fuse board from 90' will need to be replaced with duel RCD one. Lights should be separated between two RCD sites. The circuits for shower,,,, power cannot be taken from any other source than directly from CCU !!! ( very dangerous ) , and the 2 showers must have they own supply from CCU ( cannot be connected together ). Power to the garage? Preferably separated circuits from CCU but if you need this for just fridge of freezes and lights,,, this can be taken from socket outlet with 13A fused spur.
