Hi, I’ve just had some concrete down and he has put no drainage down. He has sloped it about 30degrees away from the house. The space is 3m wide x 15m length. Do you believe drainage would be required and does anyone foresee any issues as a result?

A concrete apron on the house perimeter should have proper drainage that doesn't allow water to pool next to the path. You also have to be aware that the house wall also serves as a catchment area during wind driven rain. Is there room to add drainage? Photos?
Do you know your soil classification?
To comment on your minimum required slope, you need to post your location so that responders know your area's rain intensity. A 30 degree slope is a lot, what does your quote/contract state?
Re drainage, a concreter will only do what you have contracted him for, what does your quote state?
A concretor is rarely also a plumber. Drainage is connected to a silt pit that drains to stormwater. Was this discussed prior to quoting?
What gap is there between the bottom of the weep holes (DPC) and the concrete next to the wall?

yes you can, you needs spacing between pipes but electrical will be below 500mm and you can lay the ag line just under the turf. Make sure there is marker tape at 300mm,…
