Installation of electric built in oven

Question

Hi I am wanting to buy a new electric oven. At the moment I have a electric oven, but when it gets to a high temperature it fuses the house electrics. I only have a normal double socket. Would I need a cooker point installing, and if so, how much roughly for that and to install the oven.

Hi

You should install a new cooker circuit direct from consumer unit 10mm radial circuit to a cooker switch 45amp then to a cooker/hob outlet 

Depending on the length of the run and how difficult it would be. It would be hard to quote you without looking.

Most new electric ovens operate around 10-13 amps 
As long as it’s less than 3 kw it’s no problem on a plug 
I suspect from what you say there is an internal issue with your current oven
If the RCD is tripping it’s an earth leakage fault if it’s the mcb tripping it’s a short circuit which normally happens when the element is going 
So In answer to your question buy an oven less than 3kw and plug it in

Bill · Answer

Yes and no if your new oven is fan assisted it will run off of a 13amp plug you can check this on purchase 
If it’s not fan assisted you will need a new supply 
Cost £250 to supply and install

Hello
Need to know the wattage of the new oven
If your current oven is tipping MCB or RCD likely have issues already
You need to invest some money getting it made safe and then get some advice from them

Naeem · Answer

Yes, I believe you will need a sparky to put a socket with greater amps to avoid fuse breaking.

Adrian · Answer

Depending KW it might need cable to be increased by size 
Also new cable from CU to Cooker point

Matthew · Answer

Some ovens can be installed into a socket but it depends on manufacturers instructions. 

It is advisable to have a designated cooker circuit, so if a fault occurs it doesn’t impact the cooker or the cooker impact other parts of the property. 
Fitting a new circuit for a cooker require building control to be informed. As the property owner, you are responsible for ensuring that building control are notified or ensure the electricians is on a CPS scheme and they will complete the relevant documents and notifications for you. 

Depends on location but to install a new circuit could vary from 100 to 300 pounds depending on the location of the fuse board and the cooker. 
Also before a new circuit is installed an electrician needs to ensure the electrics are safe and certain standards are complained about. Therefore meter tails, bonding and RCD’s will all need to be checked to confirm they are adequate.

Samuel · Answer

It is good to inform a model of an electric oven that you want to buy. So it is possible to answer which cabling and electrical grid needs to be placed in the house.

Simon · Answer

By the sounds of things, the oven is wired into the existing kitchen ring.
I would recommend running a new cable from the consumer unit and having a separate circuit just for the oven. Depending on space In the board and RCD protection.

Ryan · Answer

All ovens have different Kilowatt load sizes but most new electric ovens can be plugged into ring main. When you purchase check the manufacture instructions for installations and this will clearly tell you if needs an individual circuit or can come off the socket ring main circuit with a plug or fused spur. The cost of the new circuit will depend on the KW of the oven and the length of cable run from fuse box to oven isolation switch as an increase in cable size and length will incur the larger cost and will be required by calculations to find this by the electrician.
From around £300 for 6mm T&E in average-sized property.

Kevin · Answer

Generally, the oven should be on its own supply,  thus taking the risk of overloading the socket circuit fuse, When using large items eg. Washer. Drier,  dishwasher.  
The cost depends on how the cable is installed and its length.  Average cost likely between 
£250 / £350.

Joshua · Answer

Sometimes the heating element within the oven can be replaced if broken, rather than replace the whole unit.

If you would like to check this first, then an "Appliance electrician/technician/repair person" or some Electricians will diagnose this and replace if necessary.

In some situations, it works out cheaper to just replace the element, but the gamble is in whether or not it's the element that is faulty or possibly a different part that still requires you to replace the oven fully anyway.

Alternatively, New oven units sometimes come with a plug, often small units do not require a huge power supply and therefore come fitted with a 13A plug from the factory. 

Some units do not come with any cable, they would need to be hard-wired in by a competent person, this can sometimes be connected to the plug socket supply cable via changing the socket back box, socket faceplate + possibly a breaker at your fuse board/consumer unit also.

Some ovens will require a brand new supply cable to your cooker as they require a large electrical supply.

Maybe if you buy a new unit, it may be easiest for you to look out for one with a plug attached from the manufacturer.

Costings approx
To install an oven with a plug to connect to a currently installed socket + fitting consumables + labour = £65-£125

To install  a new back box + fused spur for a small (under 13a) oven unit + cable to oven + consumables + labour = £85-£185

To Install a new supply cable @ 4/6/10mm + Breaker + Oven connection unit + consumables  + labour = (Depends greatly on the distance and route between your fuse board/consumer unit and your oven location) £125-£350

Hope this helps

Kind regards

hi, my name is Chris. Most of the normal modern ovens will take a load of no more than 2.3kw and that is fine on a 13 amp plug. But it depends on the loading of the circuit it plugs into. Now the fun and the guessing starts for you though. Sometimes if an element has a fault on it, that fault only appears at high temperature and it will trip out, and so when the oven cools down, there is no fault there.  You could separate the circuit for it but that may not solve the problem. Is it an mcb that trips or an rcd that protects a number of circuits?
