NELIYI is a Member Institute of Iyengar Yoga (UK) Ltd. IY(UK) - which you'll often hear referred to by its old name, the 'Iyengar Yoga Association' or 'IYA' - provides a network of information about Iyengar Yoga and yoga events in the United Kingdom. Many groups of members have formed Institutes or local groups (such as NELIYI) which share information and hold events on a local scale; others remain as individual members. All members receive the twice-yearly magazine, Iyengar Yoga News. Iyengar Yoga (UK) Ltd., as the professional organisation of Iyengar yoga practitioners in the UK, is also responsible for maintaining standards of teaching of Iyengar yoga, and for the assessment and certification of those wishing to teach. All Iyengar yoga teachers in the UK must belong to IY(UK) and hold the Iyengar Yoga Certification Mark.
Members of NELIYI are automatically members of IY(UK), so will receive a copy of the Iyengar Yoga News magazine twice a year. Also, IY(UK) members are invited to attend an annual yoga convention, at which distinguished yoga teachers from the UK, India and elsewhere lead classes.
