About us

We understand the importance of effective communication and strive to speak your language without ambiguity.

Founded in 1897, we have remained at the forefront of Scottish commerce by consistently and successfully helping businesses, charities, social enterprises and private individuals to account, comply, plan and forecast their future financial, business and personal requirements.

From our offices in Glasgow, we provide a range of audit, accounting, tax business advisory, corporate finance and financial services (Martin Aitken Financial Services Ltd).

We have grown and secured our market position in our 125-year history through organic growth, and a number of strategic mergers with other practices and continue to add to our service range and offerings to meet your demands. This has enabled us to cement ourselves as one of the largest independent medium-sized firms in Scotland.
