If your service charge period starts on 1/1/18 then you should have settled your service charge (and ground rent if applicable) by 21/28th (depending on terms under your lease of transfer).
If you are registered for Direct Debit with NRM then you have nothing to worry about.
But if you pay it via Bank Transfer you need to action this immediately. Reminder letters are in the process of being issued.
If you want to avoid late payment fees and interest, contact us now to setup for Direct Debit.
