Running power to a summer house

[Original Poster]

Hi all,

I am having a garden office built in the next month and obviously need to get power into said office.

I have literally no idea whatsoever on these things, can anyone advise on what we need to do? Goes without saying I won't be doing it myself!

Thanks in advance guys.

I laid 2 x 40mm (ID) rigi-ducts for mains & comms to my garage. 16mm sq 3-core for power & plenty of Cat5e plus other stuff I need.

A 6mm sq will probably be more than sufficient for your power needs, a 3kW heater will be the biggest load. Lighting & other general power loads will be small.

How long is the run between the house consumer unit & the outhouse location?

Oh, we had this done. Able local lad who takes care of our electrical needs did it. I can rewire basic things, but this was way beyond me. He took a feed off the main distribution board, drilled through the wall, ran the cable out to an external junction box and also fitted an outside weatherproof socket; nice for the lawnmower and power-tools. Then he switched to proper armoured cable, which he buried under the paving slabs and then ran through in a little trench beside the house. Up a wall, held on with trunking, buried in the flower beds, then a cross the patio to the summerhouse, going into a weatherproof junction box and ending up as a double socket; suddenly it's like a proper room, with lights and whatnot. Super job - he charged about £200 plus bits. Oh, and I understand that if it's set up so the power can be unplugged, then it doesn't count as a permanent installation, and doesn't need planning permission, or something, but don't quote me on that.

Thts cheap. Plus bits means labour only I take it? Still good.
My install is the same, only the main length is on stakes rather than buried.
