Bosch built-in ovens cover Series 2, Series 4, Series 6 and Series 8. At one end are simple fan ovens with rotary dials, and at the other are Series 8 ovens with a digital control ring, touch controls and Home Connect, so you can control the oven from an app. Black is the most common finish, with stainless steel and white available on some Series 2 and Series 4 models.

Start with the format. Bosch single ovens have a gross capacity of 66 or 71 litres. Some Series 8 models add extras, such as a microwave function for faster cooking, steam assistance, or a cooking probe that reads the temperature inside a joint. Series 4 single ovens offer Hotair Steam, which adds moisture from a water bowl to help with baking. Bosch double ovens all have a 34-litre top oven. Built-in models go in a tall housing and have a 71 or 76 litre main oven. Built-under models fit beneath the worktop, with a 47 litre main oven. If you want to steam as well as roast and bake, Bosch steam ovens are Series 8 steam combis with a 47 litre oven. They take water from a tank you fill by hand, so they don't need plumbing in.

Cleaning is one of the clearest differences across the range. Pyrolytic ovens, in Series 4, Series 6 and Series 8, heat up to a very high temperature that turns food residue to ash, so you just wipe it away. They cost more, but they save the most scrubbing. EcoClean Direct and catalytic coatings soak up grease as you cook, though on some models they cover only the back panel. Hydrolytic cleaning uses steam to soften dirt so it wipes off more easily. The Series 2 single ovens have no cleaning aids.

To narrow it down, first decide between a single oven, a built-in double or a built-under double to suit your kitchen units. Then choose how you want to clean it. If app control, a cooking probe or steam matters to you, look at Series 8. To finish your cooking area, look at Bosch warming drawers for keeping plates and food warm, along with Bosch microwaves and Bosch hobs.
