It has been extremely hot this week, so it's possible that the mix became too hot, and/or set too quickly. Did the contractor use a retardant? Did they provide shade for the surface of the concrete, and/or arrange to keep the surface moist?See the following web site which gives you some insight into the precautions needed when pouring concrete in hot weather.https://www.totalconcrete.co.uk/news/guide-to-pouring-concrete-in-hot-weather/
Judging from these photos there's absolutely no problem. The crack in one of the photos is tiny and will have no consequence. I would not to anything to it - leave it to your contractor.Is this building work being routinely inspected by your local BCO?
