We are a little bit different and deliberately so. Our name derives from the combined height in metres of the three tallest peaks in Northern Ireland, Scotland and England, the locations in which we are currently based. 3173 is an elevated position from which to view our work and help us see further into the future. Our Group includes companies providing pension scheme trustee services, pension consultancy, administration, actuarial services and IT software development. - Dalriada is one of the UK’s largest professional pension scheme trustee companies, helping to run pension schemes to the highest standards. - Mantle reimagines defined benefit pensions administration and actuarial software. - Spence advises on and manages pension schemes in the United Kingdom and Ireland and provides pension consulting services (including Scheme Actuary services) to employers, trustees, pension plan members and professional advisers.
