'It is an exciting time to be part of the sector': Northern Ireland IT firm appoints Lurgan woman as new head of customer engagement
Mairead Coulter joins Wellington IT after 28 years with Ulster Bank as the company targets further growth across the credit union sector
Northern Ireland IT support and services firm Wellington IT has appointed Lurgan woman Mairead Coulter as its new head of customer engagement as the company enters a new phase of growth.


The appointment comes as Wellington IT continues to expand its offering of core banking services and digital transformation solutions for credit unions across Northern Ireland and the Republic of Ireland.
Coulter joined the company in 2024 following a 28-year career with Ulster Bank, bringing extensive experience in banking and customer engagement to her new role.
Based in Belfast, Wellington IT provides core banking software, digital banking solutions and a wider range of technology and professional services tailored specifically to the credit union sector.
Wellington IT supports 51 credit unions, including 47 in Ireland and four in the UK. Its customers include eight of the top 10 credit unions in Ireland. The company's core banking system is supported by approximately 50 additional products and services, while its Professional Services team works with credit unions to implement technology solutions and maximise their value.
Operating for more than 40 years and employing over 60 people from Belfast to Cork, Wellington IT has grown 40% over the last five years, reflecting sustained investment in the sector, enabling a 1:1 ratio of staff to credit union.
The company has remained 100% focused on the credit union movement throughout its history, with 16 current customers having worked with Wellington IT for more than 30 years. This includes its first two customers, who remain customers of the business today.
Over its lifetime, Wellington IT has serviced more than 2.58 million credit union accounts and currently supports 1.8 million credit union members, processing 234.9 million transactions representing €54.9 billion in value.
Mairead said: “Our customers are at the heart of everything we do, and my focus will be on continuing to strengthen those relationships and ensure we are responding to what credit unions need from their technology partners.
"Credit unions are operating in a very different environment to even a few years ago, with members expecting increasingly seamless digital services while still valuing the trust and personal connection that makes the credit union model unique. It is an exciting time to be part of the sector and I am looking forward to working closely with our customers as they navigate this transformation.”
