Nicolette Booth’s experience as a buy-to-let landlord in south London encapsulates the growing disillusionment across the UK’s private rental sector. Having bought her flat over a decade ago for £490,000 with hopes of benefiting from both capital growth and rental income, she now finds the regulatory and financial pressures increasingly burdensome. After attempting to sell at a modest gain earlier this year, she was forced to re-let the property amid market uncertainties. Mrs Booth’s story mirrors that of thousands of landlords facing a perfect storm of tax hikes, red tape, rising costs, and legislative changes set to reshape the rental landscape.

The forthcoming Renters’ Rights Bill, due to take effect by early 2026, stands at the forefront of these challenges. This legislation will ban "no fault" evictions — currently allowed under Section 21 — thereby removing landlords’ ability to evict tenants without valid reasons such as property sale or personal use. Moreover, during the first year of tenancy, evictions will be prohibited even on valid grounds, with a mandatory four-month notice period thereafter. The legislation further limits landlords to one rent increase annually, mandates two months’ notice before hikes, abolishes fixed-term contracts in favour of open-ended periodic tenancies, and outlaws rental bidding practices that allowed tenants to pay above advertised rents. Tenants will also gain the right to challenge rent increases at tribunals and protections against discrimination based on benefit receipt or family status. The bill applies an ombudsman to oversee landlord complaints and introduces a public register, seen by some landlords as a potential source of unjust reputational damage. These reforms aim to enhance tenant security and wellbeing but also impose operational burdens on landlords, especially smaller scale private investors.

Industry experts voice concern that these changes, intended to protect renters, may drive landlords away from the market. Jeremy Leaf, a London estate agent, warns that the Renters’ Rights Bill "is weighted too much towards tenants" and could prompt a significant sell-off of buy-to-let properties, shrinking supply and exacerbating rental affordability problems. This viewpoint gains support amid current trends showing high attrition: nearly a third of landlords have sold some or all properties in the past year, and data from HM Revenue & Customs indicates that the number of landlords paying capital gains tax has more than doubled over seven years, reflecting increased disposals.

This exodus is compounded by escalating costs. Government-imposed stamp duty surcharges now total 5% for landlords, with an investor purchasing a £300,000 property facing around £20,000 in tax alone. Mortgage rates have surged as well, climbing from approximately 3% in early 2022 to an average above 5%, though recent data to September 2025 indicates a slight easing with two-year fixed buy-to-let deals averaging 4.88%, largely driven by lender competition rather than renewed investor enthusiasm. Still, landlords with interest-only mortgages report monthly repayments rising markedly — from around £500 three years ago to £875 today on a typical £200,000 loan. Maintenance costs are escalating too due to skills shortages and material price inflation, often eroding rental yields.

On top of these challenges, landlords face looming requirements to meet demanding energy efficiency standards. The government proposes mandating an Energy Performance Certificate (EPC) rating of C or above for all rental properties by 2030, though this is yet to be legislated. Current figures indicate that about 60% of buy-to-let homes fall below this threshold, highlighting the scale of potential retrofit investment needed.

Taxation developments further cloud the outlook. Rumours persist of a new levy applying National Insurance contributions on rental income, which would be charged atop existing income tax. This could push a landlord with a £30,000 salary and £20,000 rental profit from paying £4,000 in tax to £5,600. Additionally, from April 2026, landlords earning more than £50,000 from self-employment or property rental must submit quarterly tax filings under the Making Tax Digital scheme, increasing administrative burdens.

All these pressures contribute to a contraction in rental supply. The Royal Institution of Chartered Surveyors reports the most severe drop in rental property listings since the onset of the COVID-19 pandemic. This reduction in available homes is forecast to push rents higher, with estate agents estimating a 3% rise in the coming year amid already limited affordability.

Landlords like Lewis Crompton from Lincolnshire embody this shift. Once owning 12 properties, he has downsized to eight, citing razor-thin margins after factoring in tenant turnover costs and repairs. With modest monthly rents in Northern England, unexpected expenses such as boiler replacements often wipe out profits entirely. His strategy now involves moving assets into less administratively intensive commercial properties, social housing leases, or stock market investments, reflecting growing scepticism about buy-to-let viability.

While some established landlords remain, data shows newcomer inflows are insufficient to replace those exiting, threatening long-term market stability. The collective effect of rent reforms, tax increases, cost inflation, and regulatory demands may well mark the end of what was once considered a lucrative investment avenue for many private landlords.

At the same time, the reforms address significant social issues. The abolition of no-fault evictions responds to a stark rise in homelessness linked to such evictions, with charities like Shelter urging government action. The enhanced tenant protections also aim to improve housing quality through enforceable standards akin to social housing’s Decent Homes Standard.

However, as the rental market rebalances, key questions remain on how policymakers will navigate the competing interests of protecting tenants’ rights and sustaining an adequate rental supply without driving investment out of the sector entirely. For landlords and renters alike, the next few years will be pivotal as the sector adapts to a fundamentally altered landscape.
