Ask. You will need to provide some proof of your income single or combined, and your outgoings, and be in a position to repay the agreed amount monthly for the length of the mortgage. Any bank or building society will be happy to talk you through the process.
All building societies set their own rules but, in general, you'll probably need to have saved 10% of the purchase price of the house. (You might find some societies who require only 5% but 'zero deposit' schemes seem to be a thing of the past). The maximum amount that most banks/societies will lend is 2.5 times your annual income.
I would have to disagree with the above answer of 2.5x your income. I recently bought a house, put down a 13% deposit and got a mortgage approx 4.5 times my annual income, and would have got more if I had wanted it!
This was from one of the top high st banks, and I have never had a problem paying it! Make an appointment with your bank or building society and see what they say, it all depends on your job, prospects and eduction level.
I have never bought a house and have no idea how much its going to cost me, i know i dont have the best credit rating, like i cant get credit cards. but i will be getting a house with my partner, but he is very good with hsi money, will my credit ratign stop us from getting a house?
I've lost count of the people that thought that they're credit was too bad for a mortgage but they got it all the same. It just depends on the lender. Same answer goes for the amount that they will lend - anything from 2.5 - 4.5 times your annual income is possible, particularly if you do have none or a few financial commitments (ie. hire purchase, outstanding credit card balances, loans etc.)
