There shouldnt be, it should be a dedicated oven circuit
Oven electrics .. tripping fuse

He said it was a plug in so surely it would just be another appliance on a standard 32A ring or 20A radial?

Its shouldnt be, if its a pyrolytic oven as he said he put it on clean. As it's a Neff with floor heatng (therefore a multifunction oven) they aren't rated at 13a, even if it's not pyrolytic.

As already suggested by others if it is a trip going it could just bee the general load on the circuit.
Generally speaking kitchens are the most loaded circuit in a house especially if they also have the fridge ,freeze, washing machine, tumble drier microwave, kettle and other assorted electric devices. Firstly I would be testing it with every thing else on the circuit turned off then turn on one a time to see if it is a system circuit overload.

Post #4 he states that it’s a plug in. Pretty hard to diagnose if he doesn’t know what it actually is.Its shouldnt be, if its a pyrolytic oven as he said he put it on clean. As it's a Neff with floor heatng (therefore a multifunction oven) they aren't rated at 13a, even if it's not pyrolytic.

I would hope he is just referring to the oven isolater and its not an actual 13a socket switch. He has a problem if it is..

This was my query. When looking at new ovens recently quite a few were plug in which I assumed meant 13a standard socket.

For whatever reason, many ovens are now rated at 16A, even though they may only be 3kw, and with that is the directions to be hard wired. Very few now are plug and play.

Big difference to a plug in and an isolator

I know you know, but sadly many don't and use the wrong terms when trying to explain something .

As my point in #25, hard to diagnose if he doesn’t know what he’s got.

He said it’s a plug in but it wouldn’t surprise me if it’s rated at 20A!

Obviously I’m referring to machinery here but any machines I have over 13A need to be on a 16A plug min. Didn’t even know 3 pin domestic plugs came with anything over 13A.

They do not, but the tripping current of a 13A BS 1362 fuse is bigger than you think, it has to take about 24A for more than 30 minutes to blow on overload. Since an oven is constantly switching on and off it will work merrily away for years, just tripping out on Christmas Day before it’s an issue.
Edit: looked it up, it’s actually 1.66 x rated current, so 21.6A

For machines it’s start up spike current that does them mainly.They do not, but the tripping current of a 13A BS 1362 fuse is bigger than you think, it has to take about 24A for more than 30 minutes to blow on overload.

Be interesting what set up this oven is actually on.

Yes, we need @Mudball to fill in the gaps in our understanding.
With machinery it’s always the start up current that causes “problems”... A 63A three phase hoist might pull 200A for less that a second but it will need a D type breaker otherwise it will be tripping every time.
With some equipment you get supplied a “locked rotor” rating which you need to design the circuit for, it often leads to way over rated cables and very high switch gear to satisfy the calculations.

Yep, my planer was tripping constantly, changed the breaker types and problem solved. Radial arm saw pulls some amount of current too.

You dont normally get "start up" draw with ovens as the fan motors tend to be shaded pole at most, no start up device required.. A similar Neff pyro oven ( I assume) is 3.55kw.
However, with no disrespect to Mudball, we don't know the full specs of the installation.
However, I still think it sounds very much like and element/s is breaking down which wouldn't surprise me.

Sorry had left every one hanging... the oven seems to be working fine now!!.. Had some Yorkshire pudding last evening.
Earlier in the day, i had gone thru heating each element, and they worked fined. then finished it with doing a pyro self-cleaned it, and it was fine. It is a major relief since i thought it would another 200 quid out of pocket
Some background..
1) It is a plug in version.. I think it has a 13A fuse, but plugged into a fused spur. The ring is new and put it as part of the kitchen extension.
2) Since it was the weekend, maybe we had the laundry on, but then it should have stopped.. but no one told me tat we had a load there
3) We had some kids over and they were playing xbox in the study. It tripped them too!!. I thought they were on a different downstairs socket ring. They have a few things running on an extension board - xbox, sound bar, large monitor etc.
So i have a feeling the trip was not because of the oven malfunction but something outside it.

Probably still best to get a professional in to check things over. Not worth taking a chance with electrics - you don't want the kids to be without their xbox again, could be carnage!
