The practice
Mandair & Co has been based on Lodge Road in central Southampton since 1999. From our SO14 office, just a few minutes from Southampton Central station, our chartered accountants serve businesses and individuals across the city — from sole traders in Shirley and Portswood, to limited companies operating around the docks, to landlords managing student-let portfolios near the university.
As Southampton's economy spans marine and port-related businesses, hospitality along the waterfront, retail in the city centre, and a growing tech and e-commerce scene, our team tailors accounting support to each sector. Whether you're a marine engineering firm dealing with import VAT, a Bedford Place restaurant managing payments and payroll, or a Portswood landlord with multiple HMOs needing self-assessment tax returns and bookkeeping support, we understand the financial realities of operating in Southampton. From start-up advice for new ventures to strategic tax planning for established firms, we're here for every stage.
