Hold up was the out of square slab, the shed building contractors went on to other jobs and the fix wasn't confirmed until Monday at which point they had work booked up until at least Thursday.
All going well that means they will be onsite tomorrow and a team of four should get it done within one day.
Then the electricians have to come back, put up a PowerPoint, a light, and a 3 phase sub board and add a breaker to the house meterbox, then the surveyor has to check that work for compliance and issue a further certificate just for the shed itself and we are golden.
We have the cheque now for the final payment and handover will be Friday as planned for the house.
We will be walking through tonight; Sarah has next week off work so anything we find that needs resolving will either be done by Friday, or they will have to come in next week while she is off work.
