Section 21 validity checker

Our section 21 validity checker tool can help you find out if a section 21 notice is invalid.

How it works:

• we ask you some questions

• you select answers from a list of options

• we tell you if your answer means that a section 21 notice might be invalid

Some questions are about documents the landlord should give the tenant. For example, an energy performance certificate. If you don't know the answer, choose 'I don't know".

A section 21 notice might be invalid for more than one reason. Answer all the questions to make sure you get the right information.

We cannot guarantee the answers are 100% accurate in all cases.
