Gas Hob & Gas Oven Installation London — £260 Fixed

Gas hob and gas oven installation in London — £260 fixed, both in one visit

Installing a separate gas hob and gas oven in London is more complex than fitting a single freestanding gas cooker. A freestanding gas cooker connects to one gas supply point via a single bayonet fitting and one BS 669 compliant flexible connector. A separate built-in gas hob and a separate built-in gas oven each require their own gas connection — meaning two isolation valves, two bayonet fittings, two corrugated stainless steel flexible connectors and two separate gas tightness tests carried out using manometer equipment.

Our £260 fixed price covers both appliances installed in one London visit by a single Gas Safe registered engineer. No separate bookings. No waiting for two different tradespeople. One fixed price. One visit. One Gas Safe installation certificate covering both the gas hob and the gas oven — issued free on the same day.

Why two separate gas connections are needed — and what this means for safety

When a gas hob and a separate gas oven are both installed in a London kitchen, each appliance must have its own independent gas supply connection. This is a requirement under the Gas Safety (Installation and Use) Regulations 1998 and Gas Safe best practice. The reasons for this are safety-critical:

• Independent isolation: Each appliance can be safely isolated from the gas supply without affecting the other — essential for maintenance, repairs or emergency isolation
• Supply pressure integrity: Two appliances connected to a single supply point can cause pressure drops affecting combustion quality — particularly when both are in simultaneous use
• Leak testing accuracy: Each connection must be independently pressure-tested to confirm zero leaks — a single tightness test cannot adequately cover two separate connections
• Ventilation compliance: Two gas appliances in one kitchen require a combined ventilation assessment per Building Regulations Part J to confirm adequate air supply for both

• Gas oven: Fitted in base or under-counter unit, connected to separate gas supply via new BS 669 compliant flexible connector, gas tightness test, pressure test, combustion check, oven and grill tested, FFD tested

Gas hob and gas oven installation during London kitchen renovations

The most common reason our London engineers carry out gas hob and gas oven installation is during or immediately after a new kitchen fit. Kitchen fitters install the units, worktop, cabinetry and cabinetry cutouts — but are not Gas Safe registered and cannot make gas connections. Our engineers visit after the kitchen is installed to connect both the gas hob and the separate gas oven.

For new kitchen installations, we check that the gas supply pipework has been correctly routed to within 1.5 metres of both appliance positions, both isolation valves are correctly positioned and accessible, and both worktop cutouts are the correct size for the appliances before proceeding. Any issues with pipework routing are identified and clearly quoted before any work begins.

Gas hob and gas oven installation for landlords in London — CP12 compliance

Landlords in London who provide both a separate gas hob and gas oven in their rental properties need both appliances covered by a valid Gas Safe installation certificate. Our £260 installation covers both appliances in a single Gas Safe certificate — valid for your annual Gas Safety Record (CP12) under the Gas Safety (Installation and Use) Regulations 1998. We work with landlords and letting agents across all London boroughs with same day availability for pre-tenancy installations.

Gas hob and gas oven installation versus a freestanding gas cooker — which do you need?

This is the most common question we get about this service. The answer depends on your kitchen setup:

• If you have a fitted kitchen with a worktop — you likely need separate built-in gas hob and gas oven installation. Our price: £260
• If you have a gap between kitchen units — you can fit a freestanding gas cooker (hob and oven combined in one unit). Our price: £100
• If you have a gap between units and prefer electric oven — freestanding dual fuel cooker (gas hob + electric oven in one unit). Our price: £130
• If you have a fitted kitchen and prefer electric oven — separate gas hob and electric oven installation. Our price: £230

How long does gas hob and gas oven installation take in London?

Installing both a gas hob and a separate gas oven in London typically takes 2 to 3 hours. This covers: disconnecting and removing old appliances (if any), making both independent gas connections, carrying out two separate gas tightness tests, combustion checks on all burners of both appliances, combined ventilation assessment and issuing the Gas Safe certificate. Allow a 3-hour window for the engineer's visit.
