Admiral UK's guide to the best locks for all types of doors and windows in your home. Keep burglars out with these top tips.

Getting the right locks fitted not only makes you feel safe but can also help reduce your home insurance costs.

You should always lock all doors and windows when you go out, whether you're popping to the end of the street or downstairs in your apartment complex, keep them locked.

Keeping your doors and windows locked may be a condition of your homecontents or buildings insurance policy so make sure you check your documents.

Either way it will reduce your chances of falling victim to theft and at the very least, reduce the amount that's taken.

For optimal security consider fitting deadlocks or key operated security bolts to all external doors and key operated locks to all your accessible windows. If you do have deadlocks use them, as they make it harder for thieves to get out again.

You should also consider changing the locks when you move into a new home as the previous occupant may have copies of the keys, especially if the home was a rental property before.

If you're living in rented accommodation, speak to the landlord as you may need to provide them with a copy of the new keys.

Here are six types of lock to look out for:

  • 5 Lever Mortice Deadlock - a good quality lock will have a British Standard Kite Mark and the code BS3621 - according to Yale these locks offer the maximum security for wooden doors
