Gas Hobs Buying Guide: How to Choose the Right Size, Burners and Safety Features

Replacing a hob can look straightforward until the wrong cut-out size, unsuitable fuel connection or difficult-to-clean surface turns a kitchen upgrade into an expensive problem. UK shoppers comparing gas hobs should look beyond burner count and glossy product photography.

Three common buying traps are worth avoiding:

  • Assuming the stated width equals the worktop cut-out. A 60cm gas hob may measure around 595–600mm externally while requiring a cut-out close to 560mm wide. Always compare the installation dimensions, not just the headline size.
  • Treating burner wattage as the whole performance story. A high-output wok burner is useful for stir-frying and rapid boiling, but everyday cooking also needs a controllable auxiliary or simmer burner.
  • Overlooking installation and safety requirements. A built-in gas hob needs correct gas connection, ventilation, clearances and commissioning by a suitably qualified Gas Safe registered engineer. LPG compatibility may also require a separate conversion kit.

The specifications that matter before you buy

1. Size, layout and cut-out dimensions

The most common choice is a 60cm gas hob, generally offering four burners and a worktop cut-out of approximately 560 × 480mm, although dimensions vary by model.

A 70cm gas hob or 75cm gas hob can provide five burners without taking up the full width of a 90cm appliance. This extra space is useful when cooking with several pans, but check that the available worktop area and overhead clearances are suitable. For larger kitchens and multi-pan cooking, a 90cm gas hob offers more room between cookware, although it needs a substantially wider worktop opening.

Measure:

  • The available worktop width and depth
  • The existing cut-out, if replacing a hob
  • Clearance from walls, splashbacks and cooker hoods
  • The gas inlet and electrical connection position
  • The manufacturer’s required ventilation and installation clearances

Never assume a new hob will drop into an existing opening simply because both are described as 60cm or 75cm.

2. Burner configuration and practical heat control

A 4 burner gas hob is suitable for most everyday meals, particularly in smaller kitchens or households that usually use one or two pans at a time. A five-burner model adds flexibility for family cooking, but the arrangement matters more than the number alone.

Useful configurations typically combine:

  • An auxiliary burner for gentle heating
  • Semi-rapid burners for regular saucepan cooking
  • A rapid burner for boiling and frying
  • A wok burner gas hob zone with a high-output or multi-ring flame

For example, the Haier HAVG75TBBP has a stated 5kW double-ring wok burner, while the CDA HG9351SS lists a 5kW wok burner. These outputs can support high-heat cooking, but pan size, flame distribution and cookware quality still affect results.

A model with graduated flame settings, such as Haier’s Preci Flame system with nine settings per burner, may be easier to adjust for tasks ranging from simmering sauces to bringing water to the boil. Treat this as a control feature rather than a guarantee of cooking results.

3. Surface, supports and safety

The two common finishes are stainless steel gas hob and black glass gas hob.

Stainless steel is familiar, durable and generally forgiving of everyday use, although spills can show around burner bases. Gas-on-glass hob designs offer a smooth tempered glass surface that can be wiped down easily, but glass still needs careful handling. Do not drag heavy pans across it, and avoid using a hob with cracked or chipped glass.

Look for:

  • Removable burner caps and pan supports
  • Cast iron pan supports for stable cookware placement
  • Clear, front-mounted rotary controls
  • Automatic ignition gas hob operation
  • A flame failure safety device on each burner
  • Stated compatibility with natural gas or LPG

A flame failure device is designed to stop the gas supply if a flame goes out. It is an important safety backup, but it does not replace supervision. If you smell gas, turn off the supply if safe to do so, ventilate the room and contact the gas supplier or a qualified engineer. Gas appliances should not be installed or serviced as a DIY project.

Installation and running-cost considerations

Gas hobs require an appropriate gas connection and adequate kitchen ventilation. Many models also need a mains electrical connection for ignition and flame safety systems. Check whether the product is supplied for natural gas and whether an LPG convertible gas hob option requires separately purchased jets or a conversion kit.

Running cost depends on your tariff, burner output, cooking time, pan size and flame setting. A higher kW rating can deliver more heat, but it may also use more gas when operated at full power. Matching the pan to the burner and avoiding flames extending beyond the pan base can help reduce wasted heat.

For cleaning, allow the hob to cool fully before wiping. A genuinely easy-clean gas hob should have removable supports and burner parts, but stainless steel and glass still require non-abrasive cleaning products. Check manufacturer guidance before placing supports in a dishwasher.

People Also Ask

Do gas hobs need to be installed by a professional?

Yes. Gas connection and commissioning should be completed by a suitably qualified Gas Safe registered engineer in the UK. The installer should also check the cut-out, ventilation and required clearances.

Are five-burner gas hobs worth choosing over four-burner models?

They can be useful if you regularly prepare multi-pan meals, use a wok or cook for a family. However, a five-burner hob needs sufficient worktop width and sensible spacing between burners. For smaller kitchens, a well-arranged four-burner model may be more practical.

How long can a gas hob last?

Service life depends on installation, cleaning, burner maintenance and general use. Before purchasing, check the warranty, availability of replacement parts and the condition of seals, pan supports, ignition components and burner caps over time.
