About Us
About Our Founder
Calc Accounting Limited was founded by Louis Alper, a fully qualified ACA accountant (2016, Deloitte) with deep expertise in UK grant funding. As former Grant Audit Manager at Forvis Mazars LLP, Louis worked with over 150 clients annually, managing more than 200 grant audits every year — giving him a unique understanding of funder expectations, deadlines, and audit standards.
Having lived in nine countries and fluent in four languages, Louis brings a global perspective, clear communication, and a sharp eye for detail. Outside of work, he’s an avid sports fan — and brings the same energy and focus to helping clients succeed.
