Alex Probyn
Edinburgh-based WYM Rating has been acquired by global tax services and software provider Ryan.
The acquisition of Williams Young McKaig Ltd, a specialised commercial property consultancy, and its specialist rating division establishes Ryan’s property tax and business rates presence in Scotland.
Founded in 2012 by Richard Williams, Don Young, and Billy McKaig, WYM Rating supports landlords, occupiers, and investors through practical, market-informed advice grounded in decades of hands-on experience.
WYM Rating’s capabilities span three focus areas, closely aligning with Ryan’s capabilities: business rates and property tax; commercial property advisory; and occupier and lease advisory.
Alex Probyn, principal and practice leader of European and Asia-Pacific property tax at Ryan, said: “WYM Rating brings exactly the kind of specialised, local expertise our clients need as we expand our property tax capabilities in Scotland and across the UK.
“Scotland is an important market for us. WYM Rating’s strength in business rates and commercial property advisory, combined with Ryan’s global platform and integrated property tax capabilities, allows us to deliver clearer and more confident outcomes for clients operating in and investing across the region.”
Richard Williams and Billy McKaig, co-founders of WYM Rating, added: “WYM Rating has always maintained a client-focused approach, and this is a natural next step for our clients and team.
“Having shared values, we have worked closely with Ryan for more than 10 years, and formally joining the firm allows us to deepen that partnership while significantly expanding the scale, resources, and long-term value we can deliver.
“Ryan’s client-first culture, national reach, and reputation in property tax align seamlessly with our operations and position us strongly for the next revaluation cycle.”
Mr Williams, Mr McKaig and other team members will continue serving clients from Edinburgh as part of Ryan’s growing UK property tax practice.
