A fixed-rate mortgage deal sets the interest rate on your mortgage repayments for a pre-determined period. This means your monthly repayments will be the same each month until the end of the agreed fixed-term.

A standard variable rate, or SVR, is the interest rate that will be charged once an initial deal period on a fixed or tracker rate mortgage comes to an end. With an SVR mortgage, your mortgage payments could change each month, going up or down depending on the rate.

Interest is money you pay to lender in return for borrowing from them. You'll pay a percentage of the amount you borrowed – this is called the interest rate. You'll typically want a low mortgage interest rate, as this means you'll pay less to the lender in borrowing costs.

Level term life insurance is where the premiums and amount of cover stay the same during a policy term, unless any changes are made to the policy, regardless of when the insured person passes away. In other words, the amount of cover is 'level'.

Index linked policies mean the sum assured is boosted to keep it in line with inflation, or by a fixed percentage each year.

Decreasing term life insurance is a type of life insurance policy that pays out less over time. It's often used to cover the balance of a repayment mortgage, because the total balance of the mortgage decreases over time and will be paid off in full at the end of the term.
