What Armoured cable to feed Summerhouse ??

[G1nzo]

We have had a summerhouse built in the Orchard at the rear of the house
We want to have Power run to it .
Just for Lights and a few 13 A Sockets maybe a kettle etc

The Distance from the outside Consumer unit ( In the Garage )
is 80 Metres.
We have a quantity of 2.5mm 3 core swa Cable which was left by the previous owner ( New Colours )
Could someone advise if this cable would be good enough for the Job
Should be have the cable run in Trunking Underground ??

Thanks in Advance

2.5 would be no where big enough for the voltage drop as 80m run is a fair distance, without doing the cable calks you would be looking at either a 6 or 10mm cable over that sort of distance.

It's also going to add 1.2ohms to your fault loop value....
