Beginner guitarists are spoiled for choice. So much good equipment for little investment.
Personally I'd budget c30% for the instrument, 40% amp and some left over for things like a looper pedal/tuner.
I like the look of the Jet JS400 - it reviews incredibly, has awesome spec and looks good
For the amp the Boss Katana 50 is hard to beat - you'll pick one up second hand for £150. Its very versatile and can get very loud but also has a built in attenuator to reduce the power
A tuner is a good idea at least until you develop an ear. You'll use it forever.
A looper is also a good idea because you can record yourself and quickly identify how crap your strumming sounds!
All easily done for £500
