Electric cooker installation? please help...

I'm due to move in to a new build flat at the end of August, they were meant to be wired up for electric cookers, but there is no hard wiring point just a double socket where cooker goes, although there is a red cooker on & off switch. Builder has told me just to put a plug on it, but is this safe? If anyone can help it would be much appreciated, thanks.

Adding an extra light

To add an extra light to a room, I assume you will need to chisel out a channel from the existing light switch in order to lay the extra switch cable.. Is there an easy way to do this without damaging the existing switch cable or is it best to just assume you're going to damage it and replace it?

Bulb Wattage on an outside light

i've had an outside light installed recently. However i used a 40 watt light bulb and hence it's not that bright. Is there a wattage that is recommended for an outside light? I was thinking of replacing it with a 100 watt bulb. I've looked at the manual and the maximum wattage is 100 watts.



Shower cable 6mm or 10mm

Please advise, I have just had my flat rewired, kitchen and bathroom installers say that the 6mm cable is not sufficient for the best modern showers, that a 10mm cable should have been installed.

Both the installer and the electrician who did the rewiring are registered.

What is currently considered best practice, and if a matter of opinion, should the customer be consulted during the rewiring?



A clear decision from experienced electricians, which is helpful.

All four electricians agree that 10 is the current industry standard, including G W Electrics, who carried out the rewiring of my flat, and provided only 6 for my shower, how arrogant!

Thanks to the other 3 electricians who kindly responded to my question, if only my rewiring had been carried out by one of them.
