Convert to GBP?

[PolarBlue]

Got a load of money invested in Cryptocurrencies - but still have not been successful in actually coverting any to GBP and sending to my Bank Account.

I have tried Coinbase, but they require me to send a SEPA payment (which costs £25), and can only be done from a local branch (there are none nearby).

Are there others ways I can (easily and quickly) convert Crypto to GBP without paying ludicrous fees?
