Induction hobs now rival gas hobs for popularity in kitchens across the UK. Using our expert buying advice, you can uncover Best Buy induction hob recommendations for your home, whatever your budget.
While both induction hobs and traditional electric hobs use the same kind of energy and often look similar, they work differently.
An induction hob generates heat in the pan itself – no heat is produced unless the pan is in contact with the hob surface – whereas an electric ceramic hob passes a current through the elements under the glass surface, so the hob surface heats up whether a pan is on there or not.

If you're lucky, most of the pans you already own will work on an induction hob. They just need to contain sufficient iron to function well, and many pans do. A handy way to check this is to use a fridge magnet: if it sticks firmly to the base of the pan, that's a good sign.
Cast-iron pots and pans are full of magnetic material, and work really well on an induction hob. Just be careful not to damage the glass surface with these heavy items.
If you find that you need new pans, there's plenty of choice at a range of prices. Look for confirmation that the pans are 'induction-ready'.
If you're not ready to replace your pans – or maybe you have a favourite pan that doesn't work on induction – a lower-cost solution is a pan diffuser. This is basically a flat, round sheet of metal with a handle. When placed between the hob and the pan, it transfers heat to the pan's base.
Pan diffusers also go by other names, like induction hob discs, converter discs, adaptors and interfaces. They all refer to the same gadget and prices start at around £14.

When an induction hob is turned on, electricity (an alternating current) passes through coils beneath the hob's glass surface. This creates a rapidly changing magnetic field. When a pan that contains some magnetic material, such as iron, is placed on the hob's surface, a current is induced in the base of the pan. This current is converted into heat in the pan, which then transfers to the pan's contents.
Induction hobs are more efficient than either gas or traditional electric ceramic hobs because all of the heat generated goes into the pan, with none being lost to the air before it reaches the food. Remove the pan and heat is no longer produced.
The surface of an induction hob does get hot, but this is only because the pan transfers heat back to it.
To get the best from your induction hob, here are a few things to bear in mind.
As well as being induction compatible (see below), the base of a saucepan must be about the same size as the cooking zone it sits on in order to activate it. For example, a small or medium-sized pan won’t work on the largest zone.
To overcome this, some induction hobs have flexible or bridging zones (see 'Best induction hob features', above).
The most advanced flexible induction hobs have one big cooking zone with no delimited areas. This new technology could be something we see more of in the future.
Induction hobs can quickly produce impressive amounts of heat. If you're using a single zone to boil some water for pasta, for example, an average induction hob will take about half the time of an average gas hob.
As soon as you start using more than one zone on full power, induction hobs use a power-management system. On a standard four-zone hob, the two right-hand heating zones are linked (they share power), as are the two left-hand ones.
This means if you want to use two zones at full power, you'll get the best results by using one zone on the right and one on the left.
If you're using all zones simultaneously at full power, the total available power is shared as equally as possible. The heating zones will take turns to be on highest power, so you might find the contents of your pans cooking more slowly than you'd anticipated.
You might notice various noises coming from your induction hob, especially when using it on the higher settings. These are the most common:
The flat surface of an induction hob means that keeping it clean can be as simple as a regular wipe over with a damp cloth. Also, there's little chance for food spillages to get burnt on as the glass surface only heats up where the pan makes contact with it.
If you choose a model with touch controls – most induction hobs have these – then you won't have to clean around protruding dials and buttons.
The short answer is probably not. The British Heart Foundation advises that anyone with a pacemaker should keep at least 60cm (2ft) away from an induction hob. This is because the electromagnetic field generated by an induction hob can interfere with pacemaker settings.
While academic evidence suggests that an induction hob wouldn't cause a catastrophic change to a pacemaker's function, if you're in the market for a new hob, it's probably easier and safer to go for either a traditional electric hob or a gas model.
Medtronic, a major supplier of pacemakers, advises that if you think an item is affecting your heart device, simply release whatever you’re touching and move away from it. Any temporary effect is unlikely to cause reprogramming or damage to your pacemaker, which is designed to return to normal operation after interference.
There are many types of pacemaker and not all are affected in the same way, so before using an induction hob, those with a pacemaker should check the written information given to them when it was inserted. If you have any questions about how any appliances you use in everyday life might interact with your pacemaker, check with your clinic.
