Hi all, just looking for some advice and hopefully a consensus. Im not 17th edition but quite competent. Doing my own rewire to a high standard and then getting a fully qualified aquaintence to sign it all off. At the moment though, everyone is off on holiday and before I start I have a burning question .......

I will be doing a separate ring for the kitchen as we all know its advisable, however the rest of my downstairs is only a few sockets, is it ok to put the rest of the downstairs sockets and upstairs on one ring, then keep the kitchen on one of its own? Seems silly to have three rings when I've only got a small three bed mid terrace!




Then the main question is in the kitchen, I will have an extractor hood, single electric oven all singing and dancing modern one (no hob as its gas) and a boiler. I dont have the original box with the ratings for the oven by the way. I imagine it would be a bit of a load to shove it all on fused boxes on the same ring?

Instead I was thinking of having the extractor which is hardly any load on the ring on a fused box, then the combi condensing boiler and the single oven on a 45a+ radial. Please correct me if this needs some re-thinking?

I know you would usually just have an oven on a 45a radial but thats double ovens with hobs. Im no plumber, so does anyone know roughly the load a boiler has on a circuit? It seems silly to have a kitchen ring, radial for the oven and a separate one for the boiler? Or what about if you think the oven still needs a separate radial, having the combi boiler on the ring with the extractor and the oven on its own radial?


I've tried searching the web, but there are so many conflicting opinions that its enough to confuse anyone ...


Hopefully someone more qaulified/experienced can help? Thanks in advance.

And there lies the problem, there are no rules and it is down to opinion. However in my opionion the extractor fan can go on the kitchen ring and have 2 rings kitchen / rest of house as you have suggested. Now a boiler is probably going to be needing 5A, I always put boilers and ovens on there own and if your doing a full rewire there would be no reason not to do this you must be needing to upgrade the fuseboard to give you dual 30mA RCD protection these are usually 10 way boards giving you 5 on one RCD and 5 on the other so you should have plenty of spare ways.

Thanks a lot. Most helpful response so far as other professional opinions given are quite rude ....

I probably will do as you suggested then, keeping the boiler and oven on its own, thanks for the help ....

I've seen your post on a different forum and yes you dont always get very helpfull advice and some are as you say simply rude. I'd rather give someone some advice and guidance then let them stumble along as some of the other replies i've read would rather do.
