These are tenancies that have gone past the fixed term and are now into “periods”. A period being the time the rent is paid. i.e. every month or every 2 months etc. Notice can be served on the tenants and again you must give at least 2 months notice, but you must ensure that the notice period brings the tenancy to an end at the end of a rental period. Therefore, if the rent is paid on the 25th of each month, ensure the notice will bring the tenancy to an end on the 24th of the month. For example I receive rent from my tenants on the 25th of each month. Today is the 30th. I have to give 2 months notice and bring the tenancy to an end at the end of a rental period. As I have just missed the 24th July I can give notice to the tenants for possession of the property on the 24th October 2001 . If I had thought about it I could have given notice to the tenants on the 20th of July and had the property back on the 24th September 2001 .
Note if the rent is paid quarterly then you can only give notice to run out at the end of the quarter.
Always keep a copy of the notice served and of any covering letter.
