Hard wiring a dryer.....well, there're a few school of thought about it, in the USA things changes than europe and UK and you actually are generally *never* required to hard wire a dryer to a 240 volt hook up, they're generally already predisposed for dryers or stoves and so wires are already large enough, so the same way plugs and oulets are meant to support it...
Hard wiring it's always recomended in europe even if not *always* needed, this also and mosyly because some houses may have too small wires going to a plug, especially old homes, so hard wiring is reccomended also to make sure the wires are big enough...
but as said this is not *always* necessary as long as you use a good plug and you're sure wires can support such absorbition...even slightly underrated household plugs may be fine but hey have to be good ones....otherwise you can opt to have installed a 220/240 volt industrial outlet..

I have seen a bunch of these dryers hooked up with simple schucko plugs over here in Italy, and as far as I know they worked fine... in one case I also seen one adapted to normal italian outlets ( the large pins outlets) with adaptors from 240 volt household hook-up to industrial one:

That was a church community near here that had it for the youth dorm/summer camp self service laundry... I find italian plugs to be better than european standard schucko, they allows more absorbiton..
Anyway....
Now, since UK plugs do have an internal built-in fuse in the plugs, if fuse is old or very delicate may easily blown with a 5000 absorbition, you'd have to change it to a 18- 20 A one at least to ensure it will last the wattage (4800 watt) it will never blown for the 200-300 watts more... but likely a delicate 13 A would blown..
Uk plug fins are well more large and could support the absorbiton way more easily... this differently than europe where some bad shucko can actually over-heat and melt.... but in case of UK is more a matter of plug built-in fuse and house wirings than plug itself..
Of course is advisable to hard wire... you'll have to verify it yourself if it's the case or not...
