Electric power rating

3.3kw seems quite low but you might just be able to have your oven and hob on at the same time but don't forget that your fridge, lights and electric water heater (if you have one) also need to be able to work. You can upgrade your contract to whatever is the maximum Kw that are shown on your electrical "boletin", which is the document that the original installer handed to the house owner when it was built or last updated. If you want to update your contract, then depending on the age of the property and the state of the electrical installation, any certified electrician could confirm what the maximum Kw is that you can currently update to, and how much it would cost to update the cabling etc. to be able to raise to a higher amount. Properties older than 10 years, may need to be updated and issued a new "boletin" anyway for them to comply to current standards.

Very doubtful: you will in the house probably have at least one fridge-freezer running, a tv nor sound system, a couple of lights on, an extractor...using all four rings on a hob would use c.7kw, and an oven 2.5-3kw especially during the initial warming up. Do the math!

You could get it upgraded but if the wiring is not up to standard could mean a rewire and a fresh boletin before the energy supplier would upgrade, and of course the costs would go up.

Your 3.3 kw supply will be ok for what you need.

And don't forget that if you upgrade to a 5.5 kw supply your monthly standing charge will virtually double.

What Peter said is totally correct. I have 3.3kw but as non resident have learned how to juggle the power. Your hob is the most powerful item in the kitchen each ring being 1.5-2.5kw so it doesn't allow you to use much else as well. I use 1 ring only at a time with a halogen oven(1kw) but main oven would be a total use of your 3.3kw as Peter said. Don't forget your kettle is also 2-3kw rating so don't put on with a large ring. Washer and dishwasher could also be 2-3kw each. As others have said you need to mentally calculate all other items consuming power at same time or you will keep overpowering your potencia which is frustrating. I did get an electrician to quote for upgrade but over 7k€ realised not cost effective (old wiring and fuse box). Electricity in Spain is so behind the times.

We have 3.4 kw.

We have to work around it.

We could not use an oven and an electrical hob concurrently, so we have a gas hob (these are inexpensive)

We also juggle white goods, A/C and a 1.4kw pool pump.

We're currently having building work done, so unsurprisingly, we're having the power upgraded. This has necessitated a full rewire, including the cable from the meter (in next door's front wall) to our new distribution board.

We upgraded our Potencia 3 years ago. We were charged €100 for the electrician to get the certificate and then we were charged another €100 by Iberdrola for the privilege of changing. As someone has already stated, the monthly standing charge increases also.

However, it is much better than having to juggle things around when trying to use electrical items.

We found out the hard way!

Not sure of our house rating but if say we had the oven on and the immersion heater 'kicked in' very often the trip would go down, also sometimes the kettle being switched on or off would do the same.

The trips are very sensitive.

I think you can upgrade your trips with your supplier.

I think most house wiring systems can take the upgrades.

Of course upgrading means the companies charge more!

Not long after I bought my apartment, I got rid off my 2000 watt electric kettle,1100 watt toaster, along with a old oven. Replaced with a 700 watt toaster, an old fashioned whistling kettle for gas hob, halogen oven. No more electric tripping. Noticeably cheaper electric bills!!

Yes, when we come over again we will get a kettle with a lower power rating, we learned to juggle our use of washing machine, etc, etc

It can be done.
