Does anyone know how to end a assured shorthold tenancy?

[answerme1]

I just signed it a couple of days ago and now I'm regretting it big time, I have now notice the bathroom sink stands on a wooden plank! things don't open properly, the heating doesn't seem to work! If I noticed this before I would not have signed the agreement!Help anyone what can I do?:-(

You have entered into a binding contract so you are stuck, after all would you be happy if the Landlord wanted to cancel the contract because he had changed his mind.
I presume that before agreeing to the contract you were given a copy of the Energy Performance Certificate, if you paid a deposit this has been registered with a deposit protection scheme and if you have gas he has supplied the Landlords Gas Safety Certificate.
If he has missed any of these then tell him that his best action would be to release you as you could cause him more trouble.
Turning now to the faults make a detailed list and the priority that you want them fixed, I suggest that you start with the heating. Tell the landlord or their agent that you expect the work to be carried out in a reasonable time period.

The only major point that stands out in your post seems to be the heating problem. Perhaps you simply need to be shown how the heating controls work? If this is the case, contact the agent or landlord.

If the heating is really not working then the landlord has a duty to fix this. You should report the problem to the agent or landlord in writing and allow approximately 3 - 5 days for the problem to be sorted after which you can obtain 3 quotes and get the work done yourself deducting the cost off the rent you pay.

Unfortunately, none of what you have described allows you to break your contract.
