Most online bingo sites offer a pretty good free bingo sign up bonus when you join and play at them for the first.  The amount a bingo player can pick up in free bingo money changes from site to site and it depends on how much the online bingo website is willing to offer at that moment in time.  Usually the bingo bonus you can pick will be between 100% and 250% and that is pretty much standard across the bingo industry.  However, as with all things which are competitive bingo sites are constantly changing their sign up offers (that's why you should check back at freebingohunter for regular updates). Recently 2 online bingo sites have really upped their free bingo sign up offers to levels which, well, frankly put the rest of the bingo deposit bonuses on offer in the shade:

Think Bingo was one of the first Bingo sites to ever advertise on TV, do you remember the advert with some lust crazed women jumping in a swimming pool?  Well thankfully they have put those days behind them and the site is now a top ten UK online bingo site.  They have recently updated their sign up offer for new customers to now be a mega 400%!  Bingo players can take advantage upto a massive £100 in free bingo money.  So if you deposit £10 when you first join up Think will give you £40 in free bingo money. However, if you deposit £25 they'l give you an absolutley massive £100 of free bingo cash--well worth it! Anything you deposit between £10 and £25 will earn you 4 times the bingo money instantly. Oh and you also get a 50% deposit bonus on your subsequent deposits too! Click Here to claim £40 of free play at Think Bingo.

At Ladbrokes bingo it used to be that to qualify for the £20 of free bingo money, you'd have to deposit and spend  £10 on bingo tickets.  However, a few weeks ago they changed their free bingo sign up offer and made the initial deposit needed to be only £5.  So to get £20 free all you need to do is deposit £5 and spend it on free bingo tickets and then within 24hrs Ladbrokes bingo will have added £20 of free bingo money to your account.  The main difference between the Ladbrokes bingo special offer and the Think Bingo one is that at Ladbrokes you get the bonus on £5 only, so even if you spend more you won't get any extra free bingo sign up money. But of course Ladbrokes do offer regular deposit bonuses etc to their exisiting players--infact the bank holiday could be the perfect time for that. Click Here to claim £20 free at Ladbrokes bingo.
