Can You Withdraw a S13 Notice?

Hi

Can an S13 notice to increase the rent be issued and then withdrawn or superseded by a later-dated tenancy agreement?

We have been waiting for a tenant to sign a new tenancy agreement which varies the tenancy terms. The tenant has agreed verbally but, after chasing several times, has still not signed the new AST.

The current tenancy agreement includes utility bills –due to the significant increases recently, we have agreed with the tenant a reduced rent with the tenant paying the utility bills in the future.

If the tenant does not sign the new AST in the next couple of days, we will need to serve an S13 as a fallback, even though this will likely become more costly for the tenant as we will need to factor in utility increases over the next 12 months.

Thanks!
