Start of January was the initial delivery but I eventually got it at the end of Feb. The initial wait was extended due to lots of orders at the place, from 5 weeks to 9 I think it was.
Even then my piping kit didn't arrive until mid to end March but my non-return valves have only just been refunded, I did go without those after a bit of thinking though.
It wasn't set up until after June as we had to move out of the flat for major damp works to be done, no point in setting it up in March just to tear it down in June to move out and back again.
