A guide to patio door locks

If you’re looking to save money on your home insurance, it’s a good idea to get the right locks fitted.

When you apply for home cover, insurers ask what locks you have on any outside doors or patio windows.

In some cases, you’ll get a discount off the normal premium if your property has a higher degree of security.

But beware that, in some areas, if you don’t have the right locks, the price of cover may increase.

During your home insurance application process, you’ll be asked what kind of locks you have on your patio doors to help providers assess your property’s security levels.

There are three main options. If you don’t have any of these, choose “other lock type” – and consider getting your security upgraded.

Top and bottom key-operated lock

This is the most basic patio door lock.
