No. And never, ever sell bitcoins for Paypal to anyone else either. They can do a chargeback.

If you're in the UK there aren't very many selling options. You can sell direct via localbitcoins, but again there's some scam risks. You could also look into bittylicious.com which links you to other buyers.

The most painless way would be via an exchange. There are a couple of UK exchanges but you'd be better off going with a European one like Bitstamp or Kraken as they have the volume and they're pretty slick.

Stick your coins on there, sell them and then get them to do a bank transfer back to you.
