Small landlords

A small landlord is a private individual who owns and lets a small number of residential properties, typically one to four, usually alongside other employment or as a form of pension income, rather than as a full-time business. The term has no legal definition in UK statute, but it is widely used by government, lenders and industry bodies to distinguish this group from portfolio landlords and institutional operators. According to the 2024 English Private Landlord Survey, published by the Ministry of Housing, Communities and Local Government, 83% of private landlords in England own between one and four properties. These landlords account for 51% of tenancies, just over half the sector by units, despite representing the overwhelming majority of landlords by headcount.

How many small landlords are there?

The 2024 EPLS estimated approximately 2.82 million private landlords in England, of whom the vast majority own a single property. Specifically, 45% of all landlords own exactly one rental property, accounting for 21% of tenancies. A further 38% own two to four properties, representing 30% of tenancies. The remaining 17% of landlords own five or more properties but hold 49% of all tenancies, a concentration that explains why policy changes framed as affecting "landlords" often land hardest on those with one or two properties and no support infrastructure to absorb them.

The median landlord age is 59, and nearly two-thirds are aged 55 or over. Over a third are retired. Half are women. Most own property in the same region in which they live, and around half self-manage without using a letting agent.

The small landlord business model

Most small landlords fund purchases through buy-to-let mortgages rather than commercial borrowing, which means mortgage interest rate changes and lender stress-testing criteria directly affect their viability. Many entered the sector without planning a property business, inheriting a property, retaining a former home after moving, or buying a single investment flat alongside a day job. Landlords who came into the sector without planning to are often described as accidental landlords, a distinct subset with specific compliance risks under the current regulatory regime.

Once a landlord holds four or more mortgaged buy-to-let properties, most lenders apply a more intensive underwriting process under their portfolio landlord criteria. Below that threshold, a landlord is typically assessed as a standard buy-to-let borrower.

The Private Rented Sector in England is structurally dominated by small operators, even though larger portfolios control the majority of homes. This creates a structural tension in policy-making: regulations designed for the whole sector are in practice experienced overwhelmingly by people managing one or two properties without specialist staff, legal teams or compliance systems.

Compliance, no exemptions by size

Small landlords are not exempt from any of the obligations that apply to larger operators. The same rules on tenancy deposits, Right to Rent checks, gas safety, electrical safety, smoke and CO alarms, fit for human habitation, energy efficiency, and from 1 May 2026, registration on the Property Portal and membership of a Private Rented Sector Ombudsman apply regardless of how many properties a landlord owns.

In our experience supporting self-managing landlords across the UK, the compliance burden falls disproportionately on small operators because costs and administrative overhead do not scale down with portfolio size. A gas safety certificate, an EICR report, and deposit protection registration cost the same whether a landlord owns one property or twenty.

The Renters' Rights Act 2025 and small landlords

The Renters' Rights Act 2025, which came into force on 1 May 2026, makes no formal distinction between small and large operators. All assured tenancies became periodic; Section 21 no-fault possession was abolished; rent increases are limited to once per year via Section 13 notice; and anti-discrimination rules now prohibit blanket refusals to rent to tenants in receipt of benefits or with children.

For small landlords, the practical significance is concentrated in possession. Without Section 21, regaining a property now requires a specific statutory ground under Section 8, with associated notice periods and, if necessary, court proceedings. For a landlord managing one property alongside a full-time job, the time cost and uncertainty of a contested possession is materially greater than for a professional operation with experienced letting agents and legal cover.

The 2024 EPLS recorded that 31% of landlords were planning to reduce their portfolio over the following two years, up from 22% in 2021 and 16% in 2018, with tax and legislative changes cited as the primary reason. The sector is contracting at the small end. For those who remain, operating as a regulated business rather than a casual sideline is increasingly the only sustainable model.

Frequently asked questions

Is there a legal definition of a small landlord in the UK? 

No. "Small landlord" is not defined in any UK statute. Lenders use their own thresholds, typically four or more mortgaged buy-to-let properties to trigger portfolio landlord underwriting, but this is a lending criterion, not a legal one. Government surveys and policy documents use the term descriptively, with the 2024 English Private Landlord Survey treating landlords with one to four properties as the small-scale segment.

Do the Renters' Rights Act 2025 obligations apply to landlords with just one property? 

Yes. Every obligation under the Renters' Rights Act 2025 applies to all private landlords regardless of portfolio size. This includes the abolition of Section 21, the move to periodic tenancies, annual rent increase limits, Property Portal registration, and PRS Ombudsman membership. There are no carve-outs for occasional or small-scale landlords.

What is the difference between a small landlord and an accidental landlord? 

A small landlord is defined by portfolio size, one to four properties. An accidental landlord is defined by how they came to let: typically inheriting a property, retaining a former home, or acquiring a property without intending to become a landlord. An accidental landlord is usually also a small landlord, but not all small landlords are accidental, many bought specifically to let.
