Any tips to help pay off a mortgage early?

I think a lot depends on how careful your are with money, If you are able to control how you spend, then the best kind of mortgage is probably an offset one (although the interest rate is usually slightly higher). How it works is that your cheque account (and possibly savings accounts) are linked in with your mortgage, so that any money you have in your cheque account is tied in with the mortgage, say your mortgage is £300 / month and you have £2000 paid in as salary each month, any interest earned on the salary is deducted from your mortgage interest until you withdraw the money to pay bills etc. The interest earned is equivalent to the interest rate that you pay for your mortgage, also as you don't actually get any interest then you don't pay tax on it. This usually allows you to pay extra to reduce your mortgage as well. I'm not sure how worthwile this is if you don't earn a great deal, you would need to sit down with a calculator and work out your own figures yourself.
