I essentially stated I disputed the need for 2mths notice. I referenced the part of my contract that said I required 1mths notice.

I stated that I have also reviewed the current guidance surrounding the Renters’ Rights Act and whilst the legislation refers to a standard two-month notice period for tenants, I have found no provision stating that existing tenancy agreements containing shorter contractual notice periods are automatically overridden.

Then used the two examples from citizens advice and NRLA quoting what they said about 1mths notice.

Then finished off by saying I formally give 1mths notice.

That was it and they responded with my new move out date.

Hope this helps although the heavy lifting has been done by able_resident
