Accountants in Southampton: Clear Advice, Fixed Fees, No Surprises
Every accountant claims to offer clear advice and fair pricing. Most people only find out whether that's actually true once they've already signed up, which is a fairly poor way to choose someone responsible for your tax position. It's worth being able to check beforehand instead.
Henleaze Tax Consultancy works with contractors, landlords, sole traders and small businesses across Southampton. We're based in Bristol and the distance between the two cities has never actually affected how we work with clients, since everything runs through cloud accounting, phone calls and email rather than office visits.
Southampton's Economy Still Runs on Its Port, But Not Only That
Southampton's identity is tied closely to its maritime economy, and for good reason. The Port of Southampton handles over 40 million tonnes of cargo a year and is the UK's busiest cruise port, hosting P&O, Cunard, MSC and Celebrity Cruises, alongside a growing Solent Freeport initiative expected to bring significant new investment and jobs to the region. That maritime base supports a wide engineering, logistics and marine technology sector, including newer arrivals like Ocean Infinity's robotics operations.
Southampton's economy extends well beyond the docks too, with a large NHS and healthcare workforce centred around University Hospital Southampton, and the University of Southampton, a Russell Group institution with around 24,000 students, driving one of the busiest rental markets on the South Coast.

What the Renters' Rights Act Means for Southampton Landlords
The Renters' Rights Act, which came into force on 1 May 2026, is the biggest change to the private rented sector since the late 1980s, abolishing Section 21 evictions and converting tenancies to a rolling periodic structure with new rules on rent increases.
It's a legal and operational shift more than a tax one, but for Southampton landlords managing HMOs or multiple properties, particularly given how tight the local rental market already is, it's worth reviewing tenancy agreements and rent review processes alongside your usual tax reporting, since the two often get updated together.
If anything changes in how a property is let or structured as a result, that's the point to flag it with us so your reporting stays accurate too.
