Where to buy the AEG HGX75400SM hob
🏆 Review & price summary
The AEG HGX75400SM gas hob combines five burners with a 4.0kW central Multi Crown zone, rotary controls, integrated ignition and cast-iron pan supports. It is a practical choice for cooks who value direct flame control and a dedicated wok burner, while the stainless-steel finish and LPG conversion kit add flexibility. Check the wider 745mm installation carefully, and factor in the need for Gas Safe installation and hand-cleaning of the supports.
✓ Key strengths
- ✓ Useful capacity for multi-pan cooking
- ✓ The 4.0kW central Multi Crown burner is well suited to wok cooking and high-heat tasks
- ✓ With silicone feet provide a stable base for cookware
- ✓ Thermocouple protection cuts the gas supply if a flame goes out
- ✓ Additional injectors allow conversion from natural gas to LPG
Worth considering
- The 745mm width and 560 x 480mm cut-out require more worktop space than a standard 600mm hob
- Only the central burner reaches 4.0kW; the other burners are rated from 1.0kW to 3.0kW
- Are not dishwasher-safe and must be washed by hand
- Installation is more involved than with a plug-in electric hob because it requires a compliant gas connection, ventilation and Gas Safe installation

Five burners with a useful high-output centre
The AEG HGX75400SM gas hob has five burners arranged around a central Multi Crown burner rated at 4.0kW on natural gas. That gives it a capable high-heat zone for wok cooking, searing and large pans, while the 3.0kW rapid burner and two 1.9kW semi-rapid burners cover most everyday cooking.
The fifth burner is a 1.0kW auxiliary zone, which is useful for gentle simmering and smaller pans. Burner sizes range from 54mm to 122mm, and the manual specifies suitable cookware diameters for each burner.
Straightforward controls and safety features
Rotary knobs, integrated ignition and progressive gas valves make the controls familiar and practical. The progressive valves are designed to give more precise flame adjustment than simple stepped control.
Thermocouple flame-failure protection automatically interrupts the gas supply if a flame goes out. The hob also includes a UK moulded plug and operates with a standard 220-240V electrical supply for its ignition system.
Stable cookware support
Three cast-iron pan supports provide a sturdy platform for cookware, with silicone feet intended to improve stability. Their layout also allows pans to be moved across the cooking surface without lifting them as often as on separate individual pan stands.
The trade-off is maintenance: AEG's manual states that the pan supports are not dishwasher-safe and must be washed by hand. The stainless-steel surface also needs suitable cleaning products and should be dried after cleaning to maintain its finish.
Installation and gas compatibility
This is a built-in 745mm hob with appliance dimensions of 745 x 510mm and a specified cut-out of 560 x 480mm, with a 40mm installation height. It needs more worktop space than a standard 600mm hob, so replacement installations should be checked carefully before purchase.
The hob is supplied configured for natural gas G20 at 20mbar and includes injectors for conversion to G30/G31 LPG. Gas connections must be made by a Gas Safe registered installer, and the manual requires adequate ventilation for the products of combustion.
Efficiency and everyday practicality
The official product information gives the hob an overall gas-hob energy-efficiency figure of 56.9%. The Speed Burner design directs the flame towards the pan base, which should help heat transfer during normal cooking, although it remains a conventional open-flame gas appliance rather than an electric or induction hob.
There is no smart connectivity or assisted cooking system, but that keeps the control layout simple. Its strengths are capacity, manual control and the dedicated wok zone rather than automation or advanced electronic functions.
