Oven hardwire circuit

ignore that quote, its just someones idea of fun.

If there isn't a dedicated cooker breaker in the consumer, but there is a spare space, it's a straightforward exercise for an electrician to install the circuit. Cost will depend on where the cooker is going to be in relation to the consumer unit. It could be a couple of hours work, it could be a full day.

Thanks, hoping there’s space then on the unit. Far as I can tell it should do, but can’t look and confirm until I get the keys. Hoping it’s only a few hours but obviously want it done right and safely not done quick on the cheap and therefore unsafe.

Fortunately it doesn’t need doing ASAP as my dad has a countertop halogen oven he’s willing to lend me and I’ve had my eye on an air fryer for a while and the combo will do my essentials and tide me over. Won’t be able to bake till I get a proper oven but can manage without that for a bit until I’ve saved up some money to get the wiring and an oven.

I would think it would start at £200, London could be closer to £400, But do you need to move it ready for then you knock the room out?


Just get 3 quotes and think twice if the cheapest seems too low.

Thanks. If we’re extending the kitchen then we’ll do that before getting the circuit put in (and get a professional opinion about if the wall is load bearing etc). The kitchen wants redoing anyway so I’ll probably wait until we’re getting it done to get it sorted as I don’t see the point in getting the oven out in somewhere only to redo the kitchen and decide we now want it elsewhere. The kitchen might be large enough as it is but I’ve not used it so don’t know if it’s an illusion or not and where we’d be extending it into currently seems like dead space, but we might find it useful once living there. Time will tell and think it’s probably best to see how we use the space before making any major changes.

ok link to the 0.8kw oven you saw, the one i checked on currys was 0.8kw but 35A

It can't be both!

Amps x Volts = Watts

Mains voltage is 240 volts

So

3.33 A x 240 V = 800 W (0.8 KW)

Which I agree does seem a bit low. However, an electric oven normally takes far less power than the hob (which obviously has to allow for all rings / hotplates being on at the same time.

If your oven was part of a self contained electric cooker then is is quite possible the complete cooker needed a 35A supply.

If it was just an oven, then whilst I agree 800W seems low, I very much doubt it was more than 2 to 2.5 KW.

So, as a temporary measure then just an oven rated at 2.5KW or less could safely be fitted with a 13 Amp plug and plugged in to a standard ring main socket. Not a proper long term solution though.

Distance, roughly accounting for having to follow a wall, is between 10-30m.

10m is a fair distance, 30m is a heck of a long run and may require a much thicker cable - The cable size will depend on load, wall type, and ultimately, the full length of the cable.

Even if you are only currently planning on fitting a standalone oven, it would be worthwhile future proofing the installation by using cable that can cope with an electric hob.

I’m completely guessing on lengths based on suspecting the cable I have that’s 10m (I think, could be less) won’t be long enough but that a 30m cable I have will be too long. Thanks for the advice for the hob, hadn’t thought of that but definitely something to consider as I’d like an induction hob at some point.

might be .8kW but at 35amp still needs connecting to a dedicated circuit.

That would draw about 3.3 amps at 240v. Why would it need a 30 amp dedicated circuit? There are very small ovens intended for safe use on a ring main socket.

Yes, I stand corrected . I misread 0.79kWh. It's 2.3kW actually.
I did think that 0.8 was too low for an oven.

That would still only draw slightly under 10 amps which might make an ordinary 3 pin plug rather warm. Also, if it's fitted with a standard cooker type cable you'd never get the wires into the plug terminals.
