What type of fuses are they? Wired or wylex plug in jobbies? Do you have a combination of RCD and MCB or none? If it’s all on the one fuse thats one issue, ideally your kitchen should be on its own circuit 32a to cover the white goods oven etc, if it just downstairs sockets or all sockets for the house in a fuse then you will need to get a spark in to run some new cable. It may be that the fuse rating is too low but I wouldn’t recommend just upping it to stop it from tripping as the cable might not be the correct rating and that nuisance tripping might turn into a house fire, there can be many reasons and conditions for a fault knocking the whole house off.
Sometimes with age in ovens/cookers the elements expand with heat and cool and contract, resulting in low earth fault currents which can cause rcds to trip.
It may even be a terminal screw in a plug or socket that’s loose.
Either way whenever you can it’d be best to get a recommended spark in to explain the problem and show the fault, look at options.
In the meantime it’s a case of keeping an eye on what’s been used. Turn one thing off for another.
Fuses tripping is a safety feature but there’s always the chance that it can knacker technology etc.
I’m not a time served spark btw Just a meter engineer you pick things up.
