The picture shows a woman sitting on a couch and reading the ista heating bill. She has long blonde hair and is wearing black glasses. Her top is a blue shirt and she is wearing brown trousers. While she holds the heating bill in her left hand, her right hand rests on her chin. She looks directly into the camera. The beige couch on which she is sitting stretches across the entire lower third of the picture and has a white blanket draped over the back on the left with a yellow cushion leaning against it. In the background are various pieces of furniture that suggest a living room: A floor lamp and a shelf can be seen on the right, and in the centre an open two-part door leading into another room with bookshelves. The entire background is blurred.

The picture shows a young man with glasses, leaning slightly forwards and sitting on a modern wooden bench. The bench is in a bright and cosy room. The man is wearing a light blue shirt and mustard-coloured trousers. He is holding a tablet in his hands and looking at ista's heat metering system. Behind the man, to the right of the picture, is a large floor-to-ceiling window that allows plenty of natural light into the room. A green garden with lush vegetation can be seen through the window. Next to the window is a large plant in a pot on the floor. To the right of the plant is a black radiator, which contrasts with the light and natural colours of the room. To the left of the man, part of a beige sofa is visible. Other parts of the room can be seen in the background on the left of the picture, possibly including a door or another window, which also bring light and space into the room.
