Is a section 21 bad for future rental referencing

Hi,

Thanks for any help in advance.

My assured fixed term contract is coming up for renewal quite soon. the landlord tried to make a quite a significant rent increase to sign a new contract and I have been in negotiation with him since. It has dragged - which won’t be an issue if we agree on something but it might be a problem if we don’t as it will mean I definitely won’t have time to find somewhere before the contract expires.

I know that if we don’t make an agreement it could potentially go to rolling month at a time, but it is more likely he is going to say he wants me out. If this happens he may issue a section 21 on me, and I am curious if that could affect future referencing.

Just to clarify: I have always paid my rent on time, will continue to do so, and won’t let things go to the stage where a court order is needed.

I only need to stay longer than the initial year because I need sufficient time to find somewhere new.

Thanks.
