Change to Electric Cooker from Gas
Most people make the mistake of thinking since your gas cooker plugs in for the ignition, upgrading to an electric cooker is a simple straightforward swap. Unfortunately it is often not this easy, electric cookers need a much higher current supply than an equivalent gas cooker would for just the ignition.
Electric Cooker Circuit
If you do find that you have a “cooker switch” already installed then proceed down to the next step.
If you can’t seem to find a “cooker switch”, try looking in any cupboards next to the cooker. The switch can often be installed at the back of a nearby cupboard to avoid having too many switches above worktop level.
If this proves fruitless, have a look down the back of the existing cooker to see if there is a “cooker connection point”. As an electric cooker uses a much higher current, the cooker will have to be hardwired into a dedicated connection point. An example of what this looks like is shown below:
If you find a connection point, it’s a good sign that you already have a dedicated electric cooker circuit installed. In this case, proceed to the next step….
The last method of checking we will mention is to simply have a look at your fuse board/consumer unit and see if you have a circuit labelled “Cooker”. Whilst this may seem obvious (and you may be wondering why I didn’t mention it earlier!), we see SO MANY fuse boards/consumer units with poor (or even no) labelling that this is often not a reliable indicator of what circuits are and what they supply.
Is Your Cooker Circuit Powerful Enough?
Most cooker circuits are installed as 30/32A circuits. This is pretty standard among most houses and would be suitable for the vast majority of single electric cookers/hobs (whether hotplate or ceramic).
However with the advent of modern induction hobs, which use more current than older models, it is wise to double check that your existing circuit is up to the job of supplying your new electric cooker. We also see a trend for more and more customers fitting large range type cookers, which obviously have higher current demands again.
If you do already have a cooker circuit installed, the only way to check the current rating of your existing supply is to check your fuse board/consumer unit. The fuse (or circuit breaker on more modern installs) should be labelled to indicate its use. I’ll be honest, it is common for labels to be missing or incorrect, making this awkward to an end user.
If you do have correct labels, and manage to ascertain the rating of your circuit, then you need to compare this to your planned cooker. Rather awkwardly, most cookers will not show their current requirements in AMPS (the unit shown on your installation), but rather kW (kiloWatt or 1000 Watts). A ready reckoner for this is below:
- 32A Circuit suitable for cooker upto approx 7.5kW
- 40A Circuit suitable for cooker upto approx 9.5kW
- 45A Circuit suitable for cooker upto approx 10.5kW
- 50A Circuit suitable for cooker upto approx 11.5kW (unusual to see circuits this powerful)
Sidenote On Diversity:
This is not something you will be able to calculate safely yourself and you must ensure these calculations are only done by a qualified electrician.
Quite often the cooker manufacturer will make specific recommendations over the amperage of the circuit to be fitted. Whilst this information is handy and should always be followed, sadly it often only appears in the instruction manual and not on retailer websites. It may be worth checking Google for the manual of your new cooker prior to ordering to see if your electrical installation is ready.
Being Sure Before Ordering!
I appreciate the above information can be confusing. Not only that, but if you need further verification of your cooker circuit, this can mean potential dismantling of the circuit somewhat to check (removing switches or checking inside the fuse board/consumer unit). This is potentially dangerous and should only be attempted by a professional, qualified electrician.
Whilst there are the above checks that you can complete yourself, if anything is unclear or you are uncertain, it is best to ask a qualified electrician to take a look and set your mind at ease that you have the required feed in place prior to ordering your new cooker!
Many of the high street or online retailers will offer an installation service, these are strictly to connect the cooker to an existing point. If your circuit is not of a high enough rating, or you dont even have a cooker circuit, these “installation services” will leave your new cooker and then you will have to arrange to resolve it yourself. This has happened numerous times with previous customers of ours, leaving them in an awkward position.
Finally, it must also be said that if you are planning on ditching your existing gas powered cooker, this MUST be disconnected by a gas safe engineer who can also safely cap the supply pipe off. Under no circumstances must you attempt to do this yourself, and if anyone else offers to do this for you, be sure to check their credentials out first!
Perhaps you could employ the services of a professional renovation company to complete these works, thus ensuring that all the specifics are taken care of by an experienced team.

Can you kindly give a rough estimate on the cost of changing a gas cooker to an electric hob. please can you kindly detail the process.
Hello Abi, thank you for getting in touch
There are a number of factors which would determine the work involved. If you already have a cooker circuit installed, this would just be a simple case of swapping the gas cooker with the electric hob and connecting to the existing electric cooker circuit.
If you do not have an existing circuit installed then you would need an electrician to install a new circuit. This involves running a cable from the consumer unit/fuse board all the way to the cooker and an isolation switch installed alongside the cooker. It would be impossible to give even a ball park cost for this work without having looked at it. This is because the cost involved would change depending on the route of the cable, whether the existing consumer unit has an RCD installed (or even space for a new circuit installing).
The best thing to do would be to speak to a reliable local electrician and ask them to take a look at your installation. They should be able to offer some more advice on what is needed for your exact situation and what it will cost.
Hope that was helpful?
Kind regards

Hi. Just wondered if changing from a gas cooker to to an electric oven/ceramic hob (+ new cooker circuit) would also involve changing the consumer unit as well?
Hello Andy, thanks for posting the question
I’m afraid it would be difficult to advise for sure here as I don’t know how old your existing consumer unit is and whether or not it has RCD protection.
A new cooker circuit would require the cable burying into the wall and this requires that the circuit be RCD protected to meet wiring regulations. As such, your new circuit would need to be on either an RCD protected board or else one which has the facility for RCBOs to be fitted.
Hope that helps a little?
Kind regards
