All I can say is pick this company. I first ordered a shed from a rival on-line seller. The communication from them was poor and the delay from ordering to obtaining the shed was two weeks. No one would return calls.
I ordered the same identical shed from this site and although there were some delivery problems on behalf of the freighter, Mark from Garden Sheds went beyond the call of duty to sort it for me , even offering to sort out my problems with the first shed. I wouldn’t hesitate to buy another shed from here.
