The kitchen is the last frontier of home gas use for many households. Boilers are being replaced by heat pumps, gas fires have largely disappeared, and now the cooking hob is under scrutiny. This induction cooktop vs gas comparison gives you the honest numbers for 2026 — costs, performance, emissions, and who should actually make the switch.

Upfront Costs

Gas hobs remain cheaper at the entry level. A decent four-burner gas hob from a reputable brand (Smeg, Bosch, NEFF) costs £200–500 installed, assuming gas supply is already present in the kitchen.

Induction hobs have fallen considerably in price and now start at £250–400 for a four-zone model from a comparable brand, with premium options (AEG, Miele, Siemens) reaching £600–1,200. On pure hardware cost, they’re now broadly similar.

The real cost difference lies in infrastructure if you’re switching from gas for the first time. An electrician’s work to upgrade to a 32A dedicated circuit typically costs £150–350. Older consumer units sometimes need upgrading too — add £400–800 if required. And if you’re removing gas from the kitchen entirely, a Gas Safe engineer will cap the supply for £80–150.

Total switching cost for a first-time induction installation: £400–1,300 above the appliance cost. This is a one-time investment; subsequent replacements are straightforward.

Running Costs: What the Numbers Say

Induction is significantly more energy-efficient than gas. A gas hob converts roughly 40–55% of the gas energy into useful heat at the pan. An induction hob delivers 85–90% of electrical energy directly into the pan.

At 2026 UK energy prices (electricity approximately 24p/kWh, gas approximately 6p/kWh):

  • Gas cooking energy cost: ~2p per kWh of useful heat (6p ÷ 0.47 efficiency)
  • Induction cooking energy cost: ~2.7p per kWh of useful heat (24p ÷ 0.88 efficiency)

The raw unit economics slightly favour gas at current prices. An average household spends roughly £60–90 per year on cooking energy; the difference between gas and induction is approximately £15–25 per year in gas’s favour.

That gap narrows significantly if you cook during off-peak hours on a time-of-use tariff, if you have solar panels and cook during the day, or if gas prices rise relative to electricity — which is the general direction of travel as carbon pricing increases.

Cooking Performance

Heat response on induction is almost instantaneous — reduce the setting and heat stops immediately. Gas responds quickly too, but there’s a lag from the thermal mass of the burner and pan base. For precise temperature control, induction is genuinely better.

Maximum heat output on a premium induction zone can reach 3,600–7,200W in boost mode — significantly more than most domestic gas burners (typically 3,000–4,500W at maximum). Induction boils water faster. It’s not close.

Simmer control is also superior on induction. Holding a béchamel at an exact low temperature without it catching is easier on induction than on gas, where the minimum flame is a physical constraint.

There is one genuine limitation: cookware compatibility. Induction only works with ferromagnetic cookware — cast iron, magnetic stainless steel. Check with a fridge magnet: if it sticks to the pan base, it works. Non-compatible aluminium, copper, and ceramic pans won’t function on induction. Most quality cookware sold in the last decade is induction-compatible, but worth checking before you switch.

Wok cooking is gas’s strongest remaining argument. A wok’s curved base can’t make full contact with an induction zone, reducing effectiveness. Specially designed induction wok zones exist but are an imperfect solution. If you cook high-heat stir-fry regularly, this matters.

Safety

Induction hobs are substantially safer than gas on almost every measure. There’s no naked flame, so no fire risk from tea towels or loose clothing near the hob. The surface only gets warm from residual pan heat rather than direct heating — a child touching the hob between uses won’t get burned. And there’s no carbon monoxide risk; gas combustion in a poorly ventilated kitchen is a real, if rare, health hazard that induction simply eliminates.

For households with young children or elderly family members, the safety case for induction is compelling independent of any financial argument.

Emissions: The Grid Carbon Context

UK grid carbon intensity has fallen from approximately 500 gCO₂/kWh in 2012 to under 150 gCO₂/kWh on average in 2026, with frequent periods under 80g when wind output is high.

Annual cooking emissions comparison for an average household:

  • Gas hob: approximately 120 kg CO₂e per year (combustion only, before upstream methane leakage)
  • Induction on average UK grid 2026: approximately 60–75 kg CO₂e per year
  • Induction with solar self-consumption: as low as 15–30 kg CO₂e per year

When you factor in upstream methane leakage across the gas supply chain (studies estimate 3–10% leakage, with methane’s high 20-year global warming potential), gas cooking’s full climate impact is considerably higher than combustion figures alone suggest. On emissions, induction is already cleaner for UK households and will widen that lead as the grid continues to decarbonise.

The Electrification Case

The broader argument for switching to induction isn’t just about the hob in isolation. Every gas appliance removed from a home is one fewer contract with a gas supplier — eventually allowing complete termination of the gas standing charge (currently £110–180/year) — and one step toward a fully electrified home that can run on renewables.

For households already replacing their gas boiler with a heat pump, removing the gas hob completes the picture and makes terminating the gas supply financially attractive. At that point, you’re no longer paying a standing charge for a gas pipe you’re barely using.

For most households in 2026, induction is the better choice when buying or replacing a hob. Running cost parity is close, cooking performance is superior except for wok cooking, safety is significantly better, and emissions are already lower on the UK grid.

The case for staying with gas remains strongest if you cook high-heat Asian cuisine regularly, your kitchen’s electrical supply is genuinely difficult to upgrade, or you’re renting and can’t make infrastructure changes. Otherwise, the switch makes sense — particularly if you’re already on the road to leaving gas entirely.
