Mains power under decking and through raised bed in garden

[Jobbingfella]

Sorry guys the first thing to say is I am not an electrician I am renovating a house on a tight budget (recently redundant).
I have built the framework for a raised deck which is attached the house on one side and surrounded by a block built raised bed. There is an existing surface mounted socket on the outside of the house which is a spur. I want to put in two sockets in the block built rasised bed, the first facing in towards the decking and the other through the raised bed facing into the garden.

My plan is to run conduit down to below the deck surface and then run amoured cable tacked under a joist to the first socket and then through the bed to the second.

My two questions are is running the sockets from a spur a complete no no, and is the armoured cable sufficient protection against the elements, UV etc.

Your help would be greatly appreciated.

as long as its a fused spur (FCU) then sockets off are not a issue!, but needs to be RCD protected, and is notifiable!, SWA is fine regarding the elements and needs no conduit. all enclosures etc have to be IP rated.

one spur only allowed of each socket isn't it ?

Nope, if its fused down by means of a FCU then you can have multiples.

Here is an extract from BS7671-2008 Appendix 15 shows the relations ships between sockets on a ring their spurs and radials.

not if its a radial you can have loads and loads in a long line!

All down to the cable, the protective device, etc etc etc blahdy blahdy blah

If the jobbingfella's socket outside is on a 16A MCB and it's all run in T+E (2.5) then what is being suggested is fine. It will never become overloaded.

This type of work is notifiable to your local building control(under part p of the building regulations).they usually charge £200 or even more to send someone to come and test what you do,might be cheaper to just get a registered and qualified electrician in instead of building control emptying your pockets,you might not even know about these building regs,just the fact that you said "im not an electrician",you might well be competent to do it,just a bit of advice because a lot of people dont even realise what this part p is,sure you wouldnt want to get a fine,its very rare but sometimes happens,i would probably replace the existing outside socket for an IP65 rcd fused spur and radial circuit doing what you said.

Could this be an immigration issue though

do it all in SWA (remember to use CW glands)or you could use HOFR under the decking, all has to be 30mA protected change the outside socket to a adpt box IP55/65 with a fused spur (cant spur off a spur) then off two your sockets. nice and cheap!! id get a spark to check it out though when done he'll prob say u cant its part p and u have to notify but i dont thnk you going to do that so just make sure its safe
