New oven on general plug circuit
Is this normal


No, it is normal to have an electric oven on a separate radial circuit with its own MCB in the consumer unit. For example a dedicated 32A "Cooker" circuit.

Ovens are normally hardwired through a dual-pole isolating switch adjacent to the oven.


  and/or safe?


It is safe so long as the installer calculated the loading on the downstairs ring circuit. There are formula to be used which take into account the type of appliances, the number of sockets and the conductor sizes. (see Diversity and Demand below for load calculations with examples)

The REALISTISK Oven has a total rating of 2.7 kW, which is only slightly more than a typical electric kettle. It is also less than 13A on a 230V circuit, so won't be a problem for the actual socket, 13A fused plug and cable. However you obviously can't have all four heating elements on, from cold, at the same time (top, bottom, fan &amp; grill).


  it seems to me that it would still be best to isolate the oven from the general plug socket circuit


I believe that would be normal practise.
