The Short Answer
On our estimates, connecting a new freestanding gas cooker in place of the old one costs about £75 to £150, and takes one to two hours. A built-in gas oven is £120 to £300; a new gas point is £200 to £400, and moving the supply £150 to £500.
If you're buying the cooker, I'd usually take the retailer's fitting service. Either way it must be a Gas Safe registered engineer.

Retailers' fitting prices
When we checked in October 2026, Currys charged £125 to install a freestanding or range gas cooker, £130 for dual fuel and £130 for a built-in gas oven, using Gas Safe engineers. That sits within our range for a straight swap, so if you're buying new and the gas point is already in the right place, I'd take the retailer's service and compare it with a local engineer's price.
What the engineer does
What a freestanding cooker installation involves:
- connecting the cooker with a flexible hose to a bayonet fitting on the gas supply;
- testing for leaks before the cooker is lit;
- fixing a stability chain to the back, so the cooker can't tip forward and strain the pipe;
- a gas safety certificate if you ask for one.
A built-in oven may also need a new electrical spur, which adds to the price.
Safety and certificates
- Connecting or disconnecting a gas cooker must be done by a Gas Safe registered engineer: it's the law, not advice. Ask for their Gas Safe ID card: the back lists the kinds of gas work they're qualified for. See checking a gas engineer.
- Unlike a boiler or gas fire, a cooker isn't notified under building regulations. Gas Safe Register says you can ask for a voluntary Declaration of Safety certificate instead.
- The carbon monoxide alarm rule for new gas appliances doesn't cover cooking appliances, though Gas Safe Register still recommends a yearly safety check of every gas appliance.
- Landlords must have every gas appliance and flue checked by a Gas Safe engineer at least every 12 months and give tenants the record within 28 days. See gas safety checks for landlords.
