MKS Accountants is based right here in Sidcup, at The Fold on Station Road. We have been serving individuals, sole traders, and businesses in the local area for over 40 years — and many of our clients have been with us for decades.

Our Sidcup practice
Whether you are a sole trader needing help with Self-Assessment, a landlord with rental income to report, a limited company requiring year-end accounts and Corporation Tax, or a business owner looking for ongoing bookkeeping support, we have the experience and capability to help.
Being local matters. We are not a national firm operating out of a distant call centre — we are a family-run practice based in Sidcup, and our clients can speak directly with an experienced accountant every time they get in touch. Selin Osman, FCCA, leads the firm and works closely with clients personally.
Areas we cover
Our office is in Sidcup, and from here we look after individuals and businesses right across the surrounding area. Wherever you are, you deal with the same experienced team, in person, over the phone or online.
We act for clients right across these areas, in every kind of trade, from beauty, catering and construction to IT and consultancy, estate agents, contractors and beyond.
