Your monthly payment is the principal and interest on the amount borrowed, using the standard amortisation formula over your term (commonly 25 years). UK mortgages charge no separate mortgage insurance — rates are higher at higher loan-to-values instead. Council tax and buildings insurance are paid separately.
Most lenders want at least 5–10% deposit, but a 20–25% deposit unlocks the best rates. The larger your deposit, the lower your loan-to-value and the cheaper your rate.
Usually for an initial 2 or 5 years, after which the loan moves to the lender's standard variable rate. Many borrowers remortgage at the end of the fixed period to avoid the higher SVR.
