Gas Hob Installation London

🔄

Like-for-Like Reconnection

New hob into existing worktop cutout with existing gas supply. Gas tightness test and commissioning included. The most common job — typically 45–90 minutes.

🔧

New Gas Supply Run

Install new 15mm or 22mm gas supply from the meter to the hob position. Required when adding a gas hob to a kitchen that previously had electric.

🔌

Hob Disconnection

Safe isolation and capping of the gas supply. Required before a kitchen refit. Includes removal of the existing hob and certification.

🍳

Range Cooker Connection

Freestanding range cookers (Rangemaster, Falcon, Smeg) require 22mm supply and a stabiliser chain. We size the supply and issue a commissioning certificate.

🔥

LPG Hob Conversion

Convert a natural gas hob to LPG (for properties not on mains gas). Requires jet replacement, regulator fitting, and a tightness test. Includes parts.

📋

Gas Safety Certificate

If your hob is included in a landlord gas safety inspection, we can combine the installation visit with a full Gas Safe certificate for all appliances.

✅

Gas Tightness Test

Pressure test on the hob connection and gas supply using a calibrated manometer. Confirms zero leakage before the hob is commissioned.

✅

Flex Connector Replacement

We always replace the flexible gas connector with a new UKCA/CE marked hose — old flex connectors perish and are a common source of gas leaks in London kitchens.

✅

Burner Commissioning

All burners are lit and checked for correct flame colour (blue with small yellow tips), correct simmer setting, and automatic ignition function.

✅

Isolation Valve Check

Confirm the under-hob isolation valve operates correctly and is accessible. Fit a new valve if the existing one is faulty or inaccessible.

✅

Gas Safe ID & Certificate

Engineer presents Gas Safe ID card before work. Work record left with you — you can also verify the job on the Gas Safe Register online.

✅

Building Regs Notification

Where a new gas supply is installed, we self-certify under Part P/J and notify the local London authority on your behalf.

Do I need a Gas Safe engineer to install a gas hob in London?

Yes, by law. Under the Gas Safety (Installation and Use) Regulations 1998, any work involving gas appliances in the UK — including connecting or disconnecting a gas hob — must be carried out by an engineer who is registered with the Gas Safe Register. Connecting a gas hob yourself, or having an unregistered person connect it, is illegal and voids your home insurance. In London rental properties, the landlord's Gas Safe engineer must install and certify all gas appliances. After installation, the engineer should provide a Building Regulations compliance certificate (if a new gas supply was installed) and test the hob for gas tightness and correct operation. Always ask to see the engineer's Gas Safe ID card — every registered engineer carries one and it shows which types of gas work they are certified to do.

How long does gas hob installation take in a London kitchen?

A like-for-like gas hob swap (same position, existing gas supply) takes 45–90 minutes. This covers: isolating the existing gas supply, disconnecting the old hob, fitting the new hob in the worktop cutout (or cutting a new hole if required), connecting the flexible gas connector, testing for gas tightness with a pressure gauge, lighting all burners and checking flame quality. If a new gas supply is needed from the meter — because the kitchen is being moved, or this is the first gas hob in the kitchen — installation takes 3–5 hours and requires a 22mm gas supply run from the existing meter, a new isolation valve, and a Building Regulations notification (Part J for combustion appliances). London kitchens with older pipework may require a pressure test on the existing supply before connection to confirm the system can support an additional appliance.

What types of gas hob can be installed in a London home?

We install all main gas hob types in London properties: (1) Built-in gas hobs — drop into a worktop cutout (standard sizes 60cm or 75cm wide), most common in London flats and terraces. (2) Freestanding gas cookers — free-standing unit with hob and oven in one. Requires a bayonet or flex connector. Common in London Victorian terrace kitchens where no fitted units are present. (3) Range cookers (Aga, Rangemaster, Falcon) — larger 90cm or 100cm freestanding cookers with multiple gas burners. Require a 22mm gas supply (not 15mm) and must be correctly stabilised and levelled. (4) Dual fuel range — gas hob, electric oven. Requires both gas and 240V connections. (5) LPG hobs — for London properties not connected to mains gas (some South and East London areas). Requires LPG-specific jet conversion — most hobs are supplied for natural gas and need jets changed for LPG.

Can I move my gas hob to a different position in my London kitchen?

Yes, but it requires a Gas Safe engineer and, if the gas supply needs to be extended, a Building Regulations notification. In most London kitchens, the gas supply terminates at the existing hob position — moving the hob 30–60cm within the same worktop run can be achieved by extending the existing flex connector (up to a maximum length of 1.5 metres, and only if no joints are concealed). Moving the hob to a different wall or kitchen island requires running new pipework — typically 15mm copper from the nearest accessible supply point. In London Victorian terrace kitchens, gas pipes are often concealed in the floor void; accessing and extending them can add cost. Note: gas appliances cannot be installed in a room without adequate ventilation — Building Regs Part J requires a permanent air vent if the kitchen has an extractor hood and is otherwise sealed.

What should I do if my gas hob smells of gas in my London home?

If you smell gas near your hob in a London property: (1) Do not operate any light switch, electrical appliance, or ignition source. (2) Open windows and doors immediately. (3) Turn off the gas supply at the isolation valve behind the hob (quarter-turn valve, usually under the worktop), or at the main meter isolation valve if accessible. (4) Call the National Gas Emergency Service on 0800 111 999 (free, 24/7) — this is the Gas Safe Network Emergency line covering all London boroughs. (5) Leave the property and wait outside. (6) Do not re-enter until the emergency services confirm the property is safe. Do not attempt to locate or repair a gas leak yourself. A Gas Safe engineer must inspect the hob, flexible connector, and supply pipework before the appliance is used again. Common causes of gas smell at a London hob: perished flexible connector (typically 5–10 years old), cracked gas valve inside the hob body, or a loose connection at the bayonet fitting.

What is the cost of gas hob installation in London?

Gas hob installation in London typically costs: Like-for-like reconnection (same position, existing gas supply, new hob supplied by customer): £120–£160. This covers the engineer's time (45–90 minutes), a new flexible gas connector, gas tightness test, and commissioning. New gas supply run to the hob position: £220–£380 depending on the distance from the meter and whether pipework is concealed. Range cooker connection (22mm supply, 90–100cm unit): £160–£220. Gas hob disconnection only (before a kitchen refit): £90. London call-out fees for gas work typically range from £60–£100, which we waive on all gas hob jobs. Parts (flexible hose, isolation valve, bayonet fitting) are supplied at cost. All gas hob work is carried out by Gas Safe registered engineers and includes a gas tightness test certificate.
