How many watts a hob needs is a question more people ask than you might expect. Whether you're looking for an extra cooking zone for a utility room, a compact solution for your student flat or simply want to be more mindful about energy consumption — the power output of your hob plays a crucial role. In this guide, we walk you through step by step what wattage figures mean, when you need more or less power, and how to make the right choice.
What does wattage mean for a hob?
The wattage of a hob indicates the maximum electrical power the appliance consumes. The higher the wattage, the faster the hob heats up and the more heat is available for intensive cooking. A lower wattage is more economical, but may fall short when using large pans or cooking dishes that require a lot of heat.
Important to know: the maximum wattage is the peak power. In practice, you often cook at 40 to 70 per cent of that power, especially when simmering slowly or simply reheating food.
How many watts does a hob typically use?
Most electric hobs fall between 1000 and 3500 watts per zone. Here is an overview of common power ranges and when they apply:
- 800–1200 watts: Suitable for light tasks such as boiling water, stirring sauces or frying eggs. Ideal for students, camping use or as a second cooking zone.
- 1500–2000 watts: The most versatile range. Sufficient for everyday cooking, including boiling pasta, frying meat and stir-frying.
- 2200–3500 watts: Professional or semi-professional use. Heats up quickly, suitable for large families or wok cooking at high temperatures.
Which wattage suits your situation?
The ideal choice depends on three factors: how often you cook, how many people you are cooking for and what your electrical connection can handle. A standard wall socket in the UK delivers 230 volts at a maximum of 13 amperes — equivalent to approximately 3000 watts. A hob rated at 2500 watts therefore uses that connection almost to its full capacity.
Do you cook alone or as a couple and use the hob as a supplement to an existing cooker? Then a model with 1500 to 2000 watts is more than sufficient. For families who rely on the hob as their primary heat source, a minimum of 2000 watts per zone is recommended.
Hob for students and small households
For single-person households or small flats, a compact hob with 1200 to 1800 watts is a smart choice. The appliance is energy-efficient, fits on any worktop and is easy to store. There is no need to compromise on quality — with the right setting, you can comfortably prepare everyday meals.
Hob for families and intensive use
Do you regularly cook for several people or enjoy using large pans at high temperatures? Then opt for a hob with at least 2000 watts, preferably with multiple zones. Also check that the total power of the appliance is compatible with the circuit breaker in your fuse box.
Comparison table: wattage by use case
| Use case | Recommended wattage | Number of zones | Typical use |
|---|---|---|---|
| Student / tiny house | 800–1200 watts | 1 zone | Pasta, soup, eggs |
| Flat / 1–2 people | 1500–2000 watts | 1–2 zones | Everyday cooking, meat, vegetables |
| Family / primary cooking zone | 2000–2500 watts per zone | 2–4 zones | Wok cooking, cooking for multiple people |
| Professional / heavy use | 2500–3500 watts | 2–4 zones | Rapid boiling, large pans, restaurant use |
Induction, ceramic or cast iron: does it make a difference to the wattage?
Yes, definitely. Induction hobs are more energy-efficient than ceramic or cast iron hobs because the heat is generated directly in the pan and very little energy is lost to the surroundings. This means that an induction hob rated at 1800 watts delivers greater cooking performance in practice than a ceramic hob with the same power rating.
Ceramic hobs heat the plate itself and then transfer that heat to the pan — some energy is inevitably lost in the process. Cast iron hobs are robust and suitable for high temperatures, but they too are less efficient than induction.
Energy consumption and costs: how much does cooking cost per month?
With a 2000-watt hob used for an average of one hour per day, you consume approximately 60 kWh per month. At an energy price of around £0.30 per kWh, that works out to roughly £18 per month. A more economical 1200-watt hob under the same conditions costs approximately £11 per month — a difference that adds up significantly over the course of a year.
The best way to keep costs under control: choose a hob with multiple power settings and never use more watts than the task at hand requires.
