This Bosch Serie 4 built-in single oven is a proper all-rounder, happy turning out a tray of roast potatoes one night and a sourdough loaf the next. Better insulation and smoother air flow inside mean it uses less energy while it cooks. The thermostat runs from 50°C to 275°C, so low and slow baking works just as well as a blast of heat for a crisp pizza base. Rotary dials and touch controls sit on the front, with an LED display keeping track of the timer, and the drop-down door has four glass panels plus a cool-touch front.
