The Association of Residential Lettings Agents (ARLA) is a professional membership and regulatory body for letting agents and letting agencies in the UK. ARLA recognised the requirements of the residential lettings market were so detailed and specific that a separate organisation was required to promote standards in this important sector of the property industry.

The NALS logo offers peace of mind to landlords and tenants in knowing that any firm bearing it agrees to meet defined standards of customer service, is part of a Client Money Protection Scheme and has a customer complaints procedure offering independent redress.

The Law Society of Scotland is the professional body for Scottish solicitors. They were established in 1949 and are financed by their members without any funding from Government.
