Electric cooker 2500 watts to plug into normal spain plug socket?

Hi All,

We have an old Country villa in Spain. The housing electrics were not good so the house recently has been completely re-wired to a good standard.
Due to some miscommunication with the electrician however, he forgot to create a separate circuit for the electric cooker.
Looking at the cooker, it is an old one, the Teka HWE 490 ME, The oven has a total power of 2550 watts, with a grill power of 1400 watts.
You can see in the photos where the oven power cable was connected to the old circuit (the white wiring, the other black wire goes up to be ignitition for a gas hob, now not required as we just use a lighter).

My question is, can I just connect the power cable from this old cooker to a normal plug (see other attached photo where I found a power cable that I think I could use) and just plug into a normal plug socket in the kitchen to power the cooker?
Also running on the kitchen circuit are a lightbulb, a modern fridge freezer and modern gas boiler (that needs electricity to power the display unit for it) also a kettle and toaster used occasionally. The kitchen is about 10 metres away from the main circuit board in the house.

So, would it be safe to use the cooker like this, or would it be too much for the circuit (I don't want to damage our new electric installation).
Any advice would be very much appreciated,

Trav
