Just wired a 4.25kw double oven to a spare 30amp fuse on CU.I`ve used 2.5T&E from CU to terminal box near oven.From here used 2.5mm heat resistant flex to oven, as reccomended by oven instruction booklet.The T&E used from CU totals approx 3.5m in length.Would this be considered as safe? According to \\\"home\\\" section of site 2.5mm is fine up to 4800W &20A!

Couple of points..2.5T&E can certainly handle the loading as it is around 18A at 230V or 17.5A at 240V.
However, the cable is not rated at 30A and so it should not be on a 30A breaker so you should change this to 20A.
Further, what is the distance from the consumer unit to the cooker outlet plate? So long as the cable run is shorter than about 27 meters total length you will be OK for volt drop..and being domestic I would presume that this is not an issue..

No, you need to change the whole fuse (and the base), what happens if the 20A blows for whatever reason and the person fixing it sees a 30A carrier, doesn't realise what has been done and fits 30A fuse wire?
Might be easier to purchase a 20A plug in MCB for it though, than a 20A BS3036
