Get a pro in for this one as there is much more to it than running in a bit of cable, length of run, load required, volt drop cable type, earthing and supply type. For some domestic supplies ( TNCS I think) its not recommended to extend them outside of the house so alot of the time a phase and neutral is ran from the house BD to the shed DB and them the installation is them earthed via a TT system at the shed.
So short story get a decent spark.

Could you post the quote for a pro to do the work if you get one. I am after the same and had a quote for it but think its a little pricey...
Rcd, 60ft of armoured cable, 4 double sockets and flo tube - £480.

Without knowing exactly what is getting fitted and seeing the job it might be a good price. I take it that the spark will run in the cable, drill through any walls in the way, fit distribution board in the shed, connect up cable in house and fit rcd, fit all sockets and lights in shed and wire them. Fully test installation and provide you with test cetificates. How is cable being run from house to shed? Digging trench? All in a good days work so price might be ok.
