Looking for help/advice on giving notice on rental home

[GrumpyMenopausalWombWielder]

I'm weighing up when is the right time to give notice to leave my rental home. A dispute has arisen between me/landlord/neighbour & it's really between the landlord & the neighbour so I'm sharpening up my plans to leave.

The type of tenancy agreement I have is a Short Assured Tenancy, and while I can't see a specific notice period stated in the agreement, i think (from googling) the notice period is 28 days.

I'm aiming to leave at the end of October. If I gave notice this week, I'd be giving 18 weeks notice. My understanding is if the landlord was giving notice, it would be 2 mths notice to be given. There's a possibility he could serve notice in response to bring that period down, but I'm not sure that's something he can do in response to the notice I give him 1st.

I'm also hoping to be able to serve notice before the end of this month as that's my 6 year anniversary of moving in & with the ongoing dispute with the neighbour, I suspect this presents an opportunity for the landlord to hike up my rent to deal with the cost of resolving the dispute. So my thinking is, to get in 1st, but I don't want to do that if there's a detriment for me in doing so that I'm not aware of.

Does anyone have knowledge of how these things work?

Thanks.

Everything you need to know should be here

https://scotland.shelter.org.uk/housing_advice/tenants_rights/short_assured_tenancy

how long is is your tenancy? 6 months? if so it may automatically renew and you could be stuck with another 6 months rent if you don't give notice before the end of the tenancy

It's a rolling contract, signed at the beginning & not renewed, it just rolls on regardless. But if it renews on a 6 monthly cycle, that's useful to know. It means I can think about serving notice this month anyway.

There isn't a notice period on the agreement, but my searching tells me I need to give at least 40 days notice, but the landlord as a minimum 2 mths?

That's what the Shelter advice linked above says re. notice, yes
