Gas Hob Installation & Connection

What Professional Gas Hob Connection Involves

Connecting a gas hob to the mains is more than tightening a fitting. Before the new hob goes in, our engineer isolates the supply, caps or removes the old appliance and checks that the existing pipework is sound, correctly sized and in a suitable position. The type of connection depends on the appliance.

• Hard-piped connection: built-in hobs set into a worktop are normally connected with rigid copper pipework and an isolation valve, so nothing can be strained or kinked when drawers and units are used.
• Flexible hose and bayonet: freestanding cookers are usually connected with an approved flexible hose to a bayonet fitting, with a stability chain or bracket so the cooker cannot be pulled forward onto the hose.
• Tightness test: once connected, the whole installation is pressure tested with a manometer to prove there are no leaks.
• Gas rate and burner checks: we check the appliance is burning the right amount of gas, every burner lights and holds a stable flame, and the flame failure devices shut off the gas when a flame goes out.
• Ventilation and clearances: we confirm the room meets the manufacturer's ventilation requirements and that clearances to wall units, cooker hoods and combustible surfaces are correct.

If anything is unsafe, we explain it clearly and will not leave a dangerous appliance connected. Where an older appliance is being taken out, our gas appliance disconnection service caps the supply safely.

Can I Connect a Gas Hob Myself? UK Gas Hob Connection Regulations

No. The Gas Safety (Installation and Use) Regulations 1998 require anyone working on gas fittings for payment to be on the Gas Safe Register, and they require all gas work to be carried out by a competent person. In practice that means only a Gas Safe registered engineer should connect a gas hob. A poorly made joint can leak gas into your kitchen, and a badly set-up burner can produce carbon monoxide.

DIY connection also has practical consequences. Most hob manufacturers will not honour the warranty without proof of professional installation, and many home insurance policies exclude damage caused by unauthorised gas work. When you sell or let the property, buyers, tenants and letting agents may ask who fitted the appliance. Always ask to see the engineer's Gas Safe ID card.

Gas Hobs and Cookers We Connect

• Built-in gas hobs set into a worktop
• Freestanding gas cookers and range cookers
• 4-burner, 5-burner and 6-burner hobs
• Hobs with high-output wok burners
• Gas-on-glass and dual-fuel cookers
• LPG conversions where the maker supplies a kit

Larger hobs and wok burners have a higher heat input, so we always check that the existing supply can deliver enough gas at the correct pressure before we connect them.

How Long Does It Take, and When Do You Need a New Gas Supply?

Swapping a hob onto an existing, correctly sized supply usually takes one to two hours, including testing. Allow longer if worktops need cutting or an old appliance has to be removed first.

You need a new or extended gas supply run when there is no gas point near the new position, when you are moving the hob to another wall or a kitchen island, or when the existing pipe is too small for a larger hob. Moving an existing appliance is covered by our gas appliance relocation service. If your supply has been capped for a kitchen refit, our gas appliance recommissioning service puts it back into safe use.

Gas Hob Installation Cost

The final price depends on access, the connection type and whether new pipework is needed. We confirm the price before starting, and there are no surprises on the day.

Areas We Cover

Our engineers connect gas hobs across London and the surrounding areas, including Gas Safe plumbers in Sutton, Croydon and Bromley. If your boiler is also due a check, book our boiler servicing in London on the same visit.
