Section 166 of the Commonhold and Leasehold Reform Act 2002 introduces a new requirement for landlords of long leases (as defined in the Act generally over 21 years) to send the leaseholder a notice requiring payment before the sum can be due. This provision has been brought into force by the 5th commencement order. These regulations set out the form and content of notices requiring the payment of ground rent. The additional requirements specified in reg 2 include the provision of notes for both leaseholders and landlords. The content of the notes is set out in the Schedule to the Regs, as part of the prescribed form of notice under s 166(1). In force in England on 28 February 2005; Wales on 31 May 2005
