Washer dryer for single person

Please recommend me a washer dryer, this is what I think is important to me
– should be a good washing machine first and formost (dryer will be occasional use, may get separate vented dryer when kitchen is redone)
– should be quiet
– quick wash (sub hour at 30 or 40)
– should last around 5 years
– looking to spend sub £500

I currently have a bush washing machine (came with house), which is slow and noisy . I had before (in rented proerty) a new hotpoint washer dryer which seemed much better. Not sure that hotpoint is best thing to spend own money on though
