Induction Hobs: How to Choose the Right Size, Power and Features for Your UK Kitchen

Induction hobs offer fast, responsive cooking without open flames, but choosing the right model involves more than comparing prices and appearance. A low-cost purchase can become inconvenient if the electrical connection is unsuitable, the cooking zones do not fit your pans, or the advertised flexibility is limited in everyday use.

This guide explains the main buying pitfalls and compares suitable induction hobs for different UK households, from compact kitchens and rented homes to busy family kitchens.

Common Induction Hob Buying Pitfalls

1. Assuming every built-in hob uses the same connection

A built-in induction hob may require hardwiring by a qualified electrician, particularly models with a 6kW or 7.4kW connected load. This can affect installation cost and whether the existing kitchen circuit is suitable.

Some models are designed for a standard UK 13A socket. For example, the Bosch PUG61RAA5B has a pre-fitted plug and a stated 3.0kW maximum connected load. However, it still needs an appropriate earthed socket, ventilation and a suitable worktop cut-out. Do not use an extension lead unless the manufacturer specifically permits it.

Always check the rated load, fuse requirement, connection type and installation instructions before ordering.

2. Choosing by width alone

A 60cm induction hob is a common replacement size, but the visible width is not the only measurement that matters. Many 60cm models require a cut-out around 560 x 490mm, while a 90cm model may need a cut-out around 860 x 480mm.

Measure the worktop opening, available cabinet space and ventilation clearance. A 90cm induction hob may provide more room between pans, but it is unsuitable if the worktop or kitchen layout cannot accommodate it.

3. Paying for flexible zones without checking pan compatibility

A flexible zone induction hob or bridge function can combine two areas for a griddle, roasting pan or larger cookware. However, the pan still needs a suitable flat, magnetic base and must sit within the marked or detected area.

Induction technology works with ferromagnetic cookware, such as many cast iron and magnetic stainless-steel pans. Glass, ceramic and some aluminium pans will not heat unless they have an induction-compatible base. Check your existing cookware with a magnet before replacing your hob.

Core Specifications to Check

Hob size and cooking-zone layout

  • Domino induction hob: Usually around 29–30cm wide with two zones, suitable for compact kitchens or combining with another domino appliance.
  • 60cm induction hob: Commonly provides four zones and fits many standard kitchen layouts.
  • 77cm models: Offer extra space without the footprint of a 90cm appliance.
  • 90cm induction hob: Useful for large households, frequent batch cooking and wider pan spacing.

Zone diameter also matters. A small 160mm zone may not heat a very large pan evenly, while a wider area is more practical for stockpots or griddles.

Power controls and boost function

Look for clearly stated power levels and how the hob manages total output. A hob with a boost function can provide additional power to one zone for tasks such as boiling water, but using several zones at high power may trigger power sharing.

Nine power levels are sufficient for many everyday tasks, while models with 17 levels offer more incremental adjustment between simmering and high heat. A power management system can be useful where the electrical supply has a defined limit.

Safety, timer and cleaning features

Useful features include:

  • Child lock to prevent accidental button presses.
  • Pan detection to stop heating when suitable cookware is removed.
  • Residual heat indicators to show that a zone may still be hot.
  • Individual timers for automatic zone shut-off.
  • Easy-clean black glass without raised burners or grates.

The glass surface is usually simpler to wipe than a gas hob, but it is not scratch-proof. Allow it to cool, remove spills promptly and use a suitable ceramic hob cleaner rather than abrasive pads.

Bosch PIE631BB5E Series 4 60cm Induction Hob - Black Glass

Why This Fits Their Persona: Suitable for kitchen renovators seeking a conventional 60cm layout with finer heat adjustment and automated controls.

How It Avoids the Trap

The specification clearly identifies a 7.4kW hardwired connection, helping buyers account for qualified installation rather than assuming plug-in compatibility.

Key Advantage & Pros

It provides 17 power levels, PowerBoost, QuickStart, ReStart and an individual timer with automatic switch-off.

MATCH FOR: Specific Use-Case/Heavy Users
CDA HN9626FR 90cm Linear Four Zone Induction Hob

CDA HN9626FR 90cm Linear Four Zone Induction Hob

Why This Fits Their Persona: The 90cm layout gives busy households and regular batch cooks more separation between four pans.

How It Avoids the Trap

The specification states the 86 x 48cm cut-out and 7.4kW maximum load, so worktop and electrical planning can be completed before purchase.

Key Advantage & Pros

Zone bridging supports larger cookware, while boost, keep-warm and a 0–99-minute timer add practical cooking control.

Compact and Portable Alternatives

For a small flat, annex or temporary cooking arrangement, a domino induction hob can be more suitable than a full four-zone appliance. The CDA HN3621FR is 30cm wide, has two 1.4kW zones and a 2.8kW total load. Its 13A suitability should still be confirmed by an electrician and checked against the installation instructions.

A portable induction cooker is useful as an additional cooking surface rather than a direct replacement for a built-in hob. The IAGREEA DF200-14V10 offers up to 2,000W, an eight-level power range, a three-hour timer and cookware compatibility from 12–26cm. It requires magnetic cookware and a stable, heat-resistant surface.

Frequently Asked Questions

Are induction hobs expensive to run?

Running cost depends on the appliance’s power, cooking time, electricity tariff and how many zones are used together. Induction transfers heat directly to compatible cookware, which can reduce wasted heat compared with some traditional electric cooking methods. It does not automatically guarantee lower household bills.

Can an induction hob replace a gas hob?

Usually, yes, provided the worktop cut-out, electrical supply and ventilation requirements are suitable. A qualified electrician should check the connection before installation. You will also need compatible magnetic cookware.

How long should an induction hob last?

Service life varies according to construction, installation, cleaning and frequency of use. To protect the black glass, avoid dragging pans, using abrasive cleaners or placing heavy objects on the surface. Follow the manufacturer’s maintenance and safety instructions, and stop using the appliance if the glass becomes cracked.
