PK National Eyecare Group - Supporting your Independence Preferred Suppliers NEG work closely with many of the UK’s leading suppliers, negotiating preferential terms, promotions and activity. The suppliers don’t just include frames, lenses, contact lenses and accessories, but also computer software, financial services and utilities. By negotiating as a Group we can achieve terms that a single practice wouldn’t expect to achieve and the more members we can encourage to join us and spend through the Group the better the terms we will be able to negotiate. Listed here are our current preferred suppliers, (see services page for list of service suppliers.)
