How we test

Overall score is made up of:

Toasting performance (70%): As a toaster heats up it produces darker toast, so we wanted to check the consistency of colour from run to run. To do this we toasted slices of fresh white bread over 4 runs in quick succession. We also assessed the evenness of browning across each slice. Next we checked how well the toasters dealt with a single slice, as well as bread straight from the freezer. Where a toaster has a Burgen score, we also assessed how well the toaster cooked Burgen bread.

Ease of use (30%): We assessed how easy the controls were to use, whether the toasters were easy to clean or had dirt traps, and whether the crumb tray was easy to remove and empty.

We also measured the temperature of the sides of the toasters — if these get higher than 68°C they could burn you. (None of the models in this test were higher than 68°C but the metal around the slots can still get very hot.)
