If you want a stair/hallway carpet do not use the online order system. Due to Covid we could not go to the shop so decided to order online. I measured the area of the steps and hallway. Put it all in a to scale diagram to make sure it all came out of a rectangle. Also added the extra amount the website said to and I was fully confident you could easily fit everything. I added the underlay and gripper that was auto calculated from the measurements. The when the fitter arrived they immediately said it would not fit. They said it looked like the website had calculated everything based on a square room and not stairs. So I had to pay for extra gripper and underlay from the fitters, and the bottom step of my stairs could not be carpeted. So now I will have to pay for it to be sorted or put something else down. Rang Carpetright to explain the issue and I was just told sorry, the website is not our job and we don't do refunds/compensation. Wont be using Carpetright again and I would advise others to specifically not use the online order system.
