At 91.5cm wide, the Series 6 PPM9A6I40 is one of the roomiest gas hobs we’ve tested, with five cooking zones, including a powerful wok burner to crisp your stir-fried veggies to perfection. There should be enough space to juggle multiple pans with ease then, but we know from experience that’s not always the case. Find out if the Series 6 PPM9A6I40 is up to scratch by reading the full review.

How we test hobs

11 Apr 2025

Speed

How we test speed

We measure how long the hob takes to heat 1.5 litres of water to 90°C on the middle-sized burner. The quickest (excellent) hobs take less than six minutes; the slowest take more than ten minutes.

All zones speed

Simmering

How we test simmering

We assess how well the hob can maintain a very low temperature. We aim to keep baked beans just-warm, and check to see if the hob manages this or causes the beans to dry out or harden.

Heat distribution

How we test heat distribution

We measure how evenly heat is distributed across the burner/cooking zone. This is important when you are cooking something you cannot stir, such as a pancake. Some hobs have noticeable hotter and cooler spots that we measure using an infra-red camera.

Temperature overshoot

How we test temperature overshoot

We record how quickly the hob responds when it's turned off. Some hobs - especially electric ceramic hobs - hold onto heat for a long time, whereas others cool down quickly.

Ease of use

How we test ease of use

We assess how easy the controls are to use and how easy the programmable features are to set.

Ease of cleaning

How we test ease of cleaning

We assess how easy it is to clean the surface of the hob and around the dials. Gas hobs are usually trickier to keep clean because of the burners and pan supports.
