Gas vs. Induction Hobs: Energy Costs, Performance and Installation Differences

1 Apr

Choosing between gas and induction hobs depends on your priorities. Induction hobs are more energy-efficient and quicker to heat, offering precise temperature control and a sleek design but they can cost more upfront and may require electrical upgrades. Gas hobs are cheaper to run in the UK due to lower gas prices, provide instant heat, and work with any cookware, but they’re less efficient and harder to clean. Installation also differs: gas hobs need a Gas Safe engineer, while induction hobs require sufficient electrical capacity.

What Are Gas and Induction Hobs?

When choosing a hob for your kitchen design, the two most common options are gas and induction. Each operates differently and offers distinct benefits depending on your cooking style and energy preferences.

Gas hobs are the traditional choice, using an open flame powered by mains gas or LPG. When you turn the dial, gas flows to the burner and is ignited, producing instant heat. This method offers visible flames and precise temperature control, making it a favourite among many home cooks and professional chefs. Gas hobs are also compatible with all types of cookware, from cast iron to stainless steel.

Induction hobs, on the other hand, use electromagnetic energy to directly heat the base of your pan. When a magnetic pan is placed on the hob, the energy activates and heats the cookware itself, not the hob surface. This results in rapid heat-up times and excellent energy efficiency. The smooth, flat glass design is easy to clean and gives a sleek, modern look to any kitchen renovation.

Induction cooking has grown in popularity across the UK, particularly in energy-conscious homes looking to reduce carbon emissions and electricity use. It's also a safer option, as there are no open flames and the surface remains cool to the touch when not in use.

Energy Efficiency & Running Costs

When considering long-term value, energy efficiency and running costs are key factors in choosing between gas and induction hobs.

Gas hobs typically have a lower cost per unit of energy, as mains gas is cheaper than electricity in the UK. However, gas cooking is less efficient - only around 40–60% of the energy actually heats the pan, with the rest lost as heat around the burner. This inefficiency means gas hobs often use more energy overall to cook the same meal.

Induction hobs, while usually more expensive to purchase and install, are far more energy-efficient. Around 90% of the energy is transferred directly into the pan, thanks to the precise electromagnetic process. This not only means quicker cooking times but also lower energy waste, which can translate to savings over time.

Cost Comparison Example (UK)

For a typical family cooking daily:

Gas hob: ~£40–£60 per year in energy use
Induction hob: ~£60–£80 per year in electricity costs

While induction may cost slightly more to run due to electricity rates, its efficiency and speed can offset this difference, especially with energy-conscious habits.

Cooking Performance & Control

When it comes to day-to-day cooking, both gas and induction hobs offer thier own advantages depending on your preferences and cooking style.

Gas hobs provide instant visual control via the flame, allowing cooks to quickly adjust heat by eye. This tactile feedback is a major reason why many professional chefs still favour gas, especially for techniques like stir-frying where quick changes in temperature are essential. Gas is also excellent for simmering, as you can finely tune the flame to maintain a gentle heat.

Induction hobs, however, shine in terms of speed and precision. They can bring a pot of water to the boil in nearly half the time of a gas hob, making them ideal for busy households. Digital controls offer accurate temperature settings, and many models include safety features like automatic shut-off, child locks, and pan detection. There’s also minimal residual heat, reducing the risk of burns.

For boiling and precision cooking, induction offers a clear edge. For those who prefer a hands-on, responsive feel when adjusting heat, particularly during stir-frying or sautéing, gas may still be more appealing.

Installation & Upfront Costs

Before choosing a hob, it’s important to understand the installation requirements and initial expenses involved.

Gas hobs are generally cheaper to purchase, with entry-level models starting around £100–£200. However, installation must be carried out by a Gas Safe registered engineer, and if your kitchen doesn’t already have a gas supply in place, adding a new gas line can significantly increase costs. On average, installation may range from £100–£250, depending on the complexity.

Induction hobs, on the other hand, usually have a higher upfront cost, with most models priced between £250–£600 or more for premium options. Installation may require a qualified electrician, especially in older homes, where the electrical system may need an upgrade to support a higher amperage connection. Installation costs typically range from £100–£300, plus any electrical upgrade expenses.

While there are currently no specific UK-wide incentives for switching to electric hobs, some local councils or energy suppliers may offer rebates or support as part of wider energy efficiency schemes. Induction hobs may also align with government goals to reduce gas reliance, especially in new-build or low-carbon homes.

Safety & Maintenance

Safety and ease of maintenance are key considerations for any busy kitchen. Here’s how gas and induction hobs compare in everyday use.

Gas hobs involve an open flame, which carries inherent risks such as fire hazards and potential gas leaks if not properly maintained. There’s also a greater chance of scorching surfaces or damaging cookware, especially if pans overheat or boil over. While safe when used correctly and maintained by a Gas Safe engineer, gas hobs do require caution and regular checks.

Induction hobs are widely regarded as the safer option. The cooking surface stays cool to the touch except directly beneath the pan, and there’s no exposed flame. Most models come with built-in safety features, including automatic shutoff, child locks, and pan detection - ensuring the hob only activates when compatible cookware is present.

In terms of cleaning, induction hobs are easier to maintain. The smooth glass-ceramic surface can be wiped clean after cooking, with no grates or burners to disassemble. Gas hobs, by contrast, require more effort, as burner parts and grates often need to be removed and scrubbed separately.

For households prioritising safety and convenience, induction hobs offer clear advantages.

Which Hob is Right for You?

Deciding between a gas and induction hob depends on your lifestyle, cooking preferences, and energy priorities.

Gas hobs are best suited to traditional cooks who enjoy the tactile control of a visible flame. They’re generally more affordable upfront and are compatible with all types of cookware. If you’re working within a budget or already have a gas supply in place, gas remains a reliable and familiar choice. They also work well on a kitchen island, offering flexibility for open-plan layouts and social cooking.

Induction hobs, on the other hand, are ideal for modern kitchens and energy-conscious households. They offer faster cooking, precise digital controls, and enhanced safety features - making them particularly attractive to families or those looking to reduce their carbon footprint. While they come with a higher initial cost, the long-term efficiency and ease of use can offer significant benefits.

For those who want the flexibility of both systems, dual-fuel or hybrid hobs combine gas burners with induction zones, allowing you to tailor your cooking experience to different needs.
