Gas vs Ceramic vs Solid-Plate vs Induction Hobs: Pros and Cons

Gas hobs burn fuel to produce a flame beneath the pan. Heat is instant and continuously variable. Turn the knob and the flame changes immediately. This makes gas well-suited to techniques that require rapid heat adjustment: high-heat stir-frying, wok cooking, charring over an open flame, and any task where visual heat feedback helps.

The efficiency disadvantage is significant. Only 40 to 55 percent of the energy produced by combustion reaches the pan. The rest heats the air, the pan supports, and the kitchen. Gas also produces indoor combustion by-products including nitrogen dioxide and particulate matter, which UK building regulations require to be extracted. A functioning cooker hood is not optional with a gas hob. Additionally, new gas hob installations are subject to increasing regulatory scrutiny as the UK moves toward electrification of domestic heating and cooking.

Cleaning is the main day-to-day disadvantage. Burner caps, pan supports, and the hob surround all trap grease and food. Thorough cleaning requires disassembly and scrubbing, straightforward but time-consuming compared with flat electric hobs.

Ceramic hobs use radiant heating elements beneath a smooth glass-ceramic surface. The elements heat the glass, which transfers heat to the pan by conduction. The flat surface is visually clean, easy to wipe down, and works with any pan material, making ceramic a popular upgrade from gas for households switching to electric without the additional cost of induction.

The principal disadvantage is residual heat. After switching off, the glass surface retains significant heat for several minutes. The surface looks identical whether hot or cold, which creates a burn risk if touched accidentally. Most models include a residual heat indicator for this reason. Heat-up is also slower than induction, and the glass can develop scratches from rough pan bases over time.

Efficiency sits between gas and induction at around 55 to 65 percent. A ceramic hob uses more energy per cooking session than induction for the same task, primarily because energy is wasted heating the glass surface and the air around it rather than going directly into the pan.

Solid-plate hobs use cast iron or steel heating plates wired to resistive heating elements. They are the oldest surviving electric hob technology and the least expensive to buy. Their primary appeal is simplicity and durability: no glass surface to crack, straightforward controls, and robust construction.

The disadvantages are substantial for everyday cooking use. Heat-up is slow. A solid plate can take 5 to 8 minutes to reach cooking temperature from cold. Cool-down is equally slow: the thermal mass of the plate retains heat long after power is reduced, making responsive temperature control difficult. Boiling, reducing, and any technique requiring a rapid heat change is less convenient than on other hob types.

Energy efficiency is low, comparable to gas, because the plates heat the surrounding air as well as the pan. Running costs per cooking session are the highest of the four types. Solid-plate hobs are most appropriate for very light cooking use where low purchase price is the decisive factor, or for replacement in an existing installation where changing the hob type would require additional electrical work.

Induction hobs generate an alternating electromagnetic field beneath the glass surface. When a ferromagnetic pan is placed over the coil, electrical currents induced in the pan’s base convert directly into heat inside the pan itself. The glass surface, the surrounding air, and any non-magnetic object placed on the hob receive no heat from the coil. This is why induction is both the most efficient and the safest technology available.

Energy efficiency of 85 to 90 percent means the vast majority of electrical energy consumed becomes useful heat in the pan. Combined with fast heat-up (comparable to or faster than gas) and instant power reduction, induction is well-suited to tasks across the full temperature range: bringing large volumes of water to the boil, maintaining a precise simmer, and anything in between.

The two considerations specific to induction are cookware compatibility and electrical supply. Cookware must be ferromagnetic. A fridge magnet sticking firmly to the base confirms compatibility. Most cast iron, carbon steel, and magnetic stainless pans work; pure aluminium and copper do not. Induction hobs above 3kW require a dedicated 32A or 40A circuit rather than a standard 13A socket, which may require an electrician if one is not already installed.
