The first step is for you to contact an indepednent
mortgage broker. Have a chat with them about your circumstances, about what sort of properties you would be interested in and what you would consider a confortable monthly repayment.
You have plenty of income to support a substantial mortgage should you wish, however your deposit level may cause you some issues. The minimum deposit level is going to be 10% of the purchase price, which would limit you to a house value of 120k which may not be sufficient for what you are hoping to buy.
However, there are other options open to you, including shared equity and shared ownership schemes, builder deposits and other options to help you with your deposit.
So speak to a mortgage broker who should be able to advise you on all of the above and answer any questions you have.
Hope that helps.
