I live at bs206dj. Which tramsmitter should I point the ariel towards to recieve the most channels ? Also do I need a wideband ariel the one that I have at the moment doesnt recieve any freeview channels at all.

Mat: Mendip, if possible, aerial horizontal.
The Portishead relay is on the top of Hanover House, although it carries PSB channels only. Aerials should be vertical.
Or Wenvoe which broadcasts PSB and COM channels, although carries the Wales regional variants of BBC One, BBC Two and ITV1. If Mendip is out and Wenvoe is therefore your only full-service transmitter, you could have another aerial pointing at Hanover House, either connected to a separate receiver or diplexed (combined) into one downlead.
For a list of services by multiplex (including which are PSB and which are COM), see:
DTG :: DTT Services by Multiplex
See ATV Sheffield's site for lots of information:
Mendip is all Group C/D so no wideband aerial is necessary. However, you may decide to get a wideband aerial just incase the authorities decide to change it all again so as to sell the spectrum off to the highest bidder...
Plus, if you get a wideband, it will also be suitable for Wenvoe (which is all Group B), should you find that Mendip isn't good enough.
If you are looking at receiving from Hanover House, then I assume that you can see its roof from yours, so a DM Log should do. Logs are wideband but have a flatter response than yagis. See here for examples:
Gain (curves), Again
I am wondering why your current aerial gives you nothing. Is there a fault that needs fixing and once it's fixed will give you the full service (if it points to Mendip)?
Even if it points to Hanover House, it will still be expected to give you PSB channels.
If your existing aerial points to Hanover House and you can get it working, then it's probably best to keep it as a backup. And if you find that Mendip isn't an option, you may decide to diplex it with one on Wenvoe.
It is worth looking to see where other aerials are pointing. Also, see if you can see anything that could be an obstruction that might be to the detriment of reception from your chosen transmitter.

JRD: You've left out a crucial bit of information - which transmitter your aerial faces!
So your aerial picks up Welsh television. But does it face Wenvoe, which is the transmitter in Wales? If it does then the answer is to look at realigning or replacing with an aerial on a transmitter in England.
If your aerial faces a transmitter in England, but your receiver keeps tuning to Wenvoe then your question relates to how you can prevent your tuner opting for the 'wrong' transmitter.
