Self-Managing vs. Using a Lettings Agent: Which Is Best for Southampton Landlords?

It’s one of the most common questions landlords face, whether they’re renting out a first property or reviewing how they manage an established portfolio. Do you handle everything yourself and keep more of the rent? Or do you hand the reins to a letting agent and pay for the expertise? Neither answer is wrong in every situation. But the calculation has shifted considerably in recent years, and the right decision now depends on factors that didn’t exist five years ago.

This guide sets out what’s actually involved in each route, what it costs, and what the current legislative environment means for landlords who are weighing it up in Southampton.

The Split Is Roughly 50/50 — But It’s Changing

According to the 2024 English Private Landlord Survey, 52% of landlords in England self-manage without using an agent, up from 49% in 2021. Around 43% use an agent to find tenants, and 18% use a full management service.

So the majority of landlords are currently self-managing. But the same survey shows why that figure is under pressure: landlords who are leaving the sector cite “increased time and hassle” as a key reason for going. The complexity of compliance is, for many, the deciding factor.

What Self-Managing Actually Involves

Self-managing a rental property is not simply collecting rent each month. Done properly, it means:

• Advertising the property, conducting viewings, and referencing applicants
• Carrying out Right to Rent checks on every adult occupant
• Drafting a legally compliant tenancy agreement
• Registering the deposit with an approved scheme within 30 days and serving the prescribed information
• Arranging and renewing a gas safety certificate every 12 months
• Ensuring a current Electrical Installation Condition Report is in place
• Providing a valid Energy Performance Certificate and meeting minimum energy efficiency standards
• Carrying out periodic property inspections and maintaining a record of them
• Handling maintenance requests, sourcing contractors, and managing repairs
• Dealing with rent arrears, serving notices, and navigating possession proceedings where necessary
• Keeping up with legislative changes as they happen

That last point has become significantly more demanding. The private rented sector is now governed by over 160 laws, and the pace of change has accelerated. Local councils received an additional £18.2 million in enforcement funding as of late 2025, meaning the consequences of an overlooked obligation are more likely to be tested.

The Real Cost of Self-Managing

Self-management is often framed as the “free” option. It isn’t. The costs are just less visible.

Most landlords managing their own properties spend between four and six hours per property per month on average. That’s time spent chasing contractors, responding to tenant queries, reviewing legislation, and handling paperwork. If your time has any meaningful value elsewhere, those hours carry a real cost.

There’s also the risk cost. A single compliance failure — an unprotected deposit, an out-of-date EICON report, a missed Right to Rent check — can result in fines, civil penalties, or the inability to serve a valid notice to regain possession. In some cases, the financial exposure from one error exceeds what a full management service would have cost over several years.

What a Letting Agent Costs

Agent fees vary by service level. Typical UK pricing breaks down as follows:

For a Southampton landlord letting at the current average of £1,248 per month (ONS, April 2026), a full management fee at 12% works out at around £150 per month, or approximately £1,800 per year.

That figure looks different once you account for the fact that letting agent fees are allowable expenses under HMRC guidance, deductible from gross rental income before Income Tax is calculated. The net cost, depending on your tax position, is meaningfully lower than the headline number suggests.

The Renters’ Rights Act: Why 2026 Is a Particularly Important Year to Get This Right

The Renters’ Rights Act is the most significant overhaul of the private rented sector since the late 1980s. Its core provisions came into force on 1 May 2026. Every landlord in Southampton needs to understand what has changed.

What is already in force (from 1 May 2026)

• Assured shorthold tenancies have been abolished. All existing and new tenancies are now assured periodic tenancies with no fixed end date.
• Section 21 “no-fault” evictions no longer exist. Possession must now be sought through reformed Section 8 grounds.
• Rent increases are limited to once per year, via a formal Section 13 notice. Landlords cannot increase rent mid-tenancy by any other means.
• Landlords must include a fixed asking rent in all property adverts. Rental bidding is prohibited.
• Blanket bans on tenants with children or those receiving benefits are no longer permitted.
• Tenants have a strengthened right to request a pet, which landlords can only refuse on reasonable grounds.

What is coming in late 2026

A new Private Rented Sector database will require landlords to register themselves, their properties, and their compliance documentation. This will roll out in phases by region.

The practical implication of all this is straightforward: the administrative and legal burden of self-managing has increased substantially, and it will increase further. Landlords who were comfortable managing their own properties under the old regime may find the new one materially more demanding.

Tenant Find, Rent Collection, or Full Management?

If you decide to use an agent, the service level you choose matters. Here’s a plain summary of what each typically covers:

Tenant Find Only The agent markets the property, conducts viewings, references applicants, and prepares the tenancy agreement. Once the tenancy starts, you take over entirely. This suits experienced landlords who are confident handling day-to-day management but want professional help with the letting process.

Rent Collection Adds monthly rent collection and arrears chasing to the above. You still handle maintenance and compliance. A reasonable middle ground if your main concern is cash flow reliability rather than day-to-day management.

Fully Managed Letting Service The agent handles everything: marketing, referencing, tenancy setup, rent collection, periodic inspections, maintenance coordination, compliance monitoring, and tenant communications. You receive a monthly statement and are consulted on significant decisions. This is the appropriate choice for landlords who want to hold property as a passive investment, those with multiple properties, or those who live some distance from their rental.

The Southampton Context

Southampton’s rental market remains active. Average private rents reached £1,248 per month in April 2026, up 3.2% year-on-year (ONS, April 2026), with steady demand from university students, NHS staff, and young professionals. One-bedroom properties have seen particularly strong rental growth, up 3.7% over the same period.

That sustained demand means well-managed properties let quickly. But it also means tenant expectations are higher, and the cost of a prolonged void or a poorly handled tenancy dispute is more significant than it might have been when rents were lower. Getting the management approach right from the outset matters more in a market like this.

Questions Worth Asking Yourself

Before deciding, it’s worth being honest about a few things:

• How confident are you in your knowledge of current landlord legislation, including the changes introduced by the Renters’ Rights Act?
• How close do you live to your rental property, and how quickly could you respond to a maintenance emergency?
• Do you have reliable contractors you can call on at short notice?
• How many properties are you managing, and how much time are you realistically able to give each one?
• If a difficult situation arose with a tenant, would you be comfortable handling it yourself?

There’s no single right answer. Some landlords are genuinely well-equipped to self-manage, particularly those with one or two local properties, a good contractor network, and the time to stay on top of compliance. Others find that what starts as a manageable workload grows quietly into something they no longer have the bandwidth for.
