Hello!
This forum is open to Jehovah's Witnesses and non-Jehovah's Witnesses so welcome.
It is largely inhabited by ex-jehovah's witnesses, jehovah's witnesses who are trying to disengage from the religion without losing their family by being shunned and by troubled jehovah's witnesses who are sick and fed up of any or all or more than failed predictions/expectations, child abuse mishandling and thinly-veiled hints and requests for money.
In answer to your question - yes you could get a Bible from their London HQ, or you could go up to one of their literature trolleys in market squares across the UK and ask for one, or into a Kingdom Hall and ask for one.
You will be given one without charge.
Alternatively go on to jw.org and it is there on line on the home page for you to click on.
Come back here any time if you have a question and you will get honest answers.
