When we first published this piece in 2018, the title was deliberately provocative: the Government, we argued, had murdered the buy-to-let market in London and the rest of the UK. Seven and a half years on, the case for that headline has only strengthened. Individual UK landlords have been selling down steadily, the tax arithmetic has become significantly harder, and a fresh wave of legislation — Section 24’s full rollout, the Renters’ Rights Act 2024, EPC reforms, and the April 2025 stamp-duty reset — has kept landlord economics under pressure. Here is what we said, what actually happened, and how the buy-to-let calculation now looks for a UK higher-rate taxpayer in April 2026.
What we said in 2018
The 2018 piece pointed to a cluster of deliberate policy choices that collectively squeezed the individual landlord: a 3% stamp-duty surcharge on second homes (introduced April 2016), Section 24’s phased restriction of mortgage interest relief (announced 2015, phased in 2017–2020), tighter Prudential Regulation Authority underwriting standards on buy-to-let lending, and an emerging patchwork of licensing and regulatory requirements at the local authority level. Our conclusion then was that the Treasury and the regulators had aligned behind a simple objective: make buy-to-let less attractive for higher-rate taxpayers to level the playing field for first-time buyers.
The prediction: a steady exodus of individual landlords, a shift of professional activity into limited-company structures, rising rents as supply thinned, and a progressive shift in where the sensible money went next.
What actually happened: the exodus was real
The net flow of landlords out of the sector is now clearly visible in the data. The English Housing Survey shows the private rented sector has been roughly flat at 4.6–4.7 million households for five years, while HMRC landlord population data and UK Finance buy-to-let redemption figures show hundreds of thousands of individual properties being sold out of the sector over the same period, with that outflow roughly offset by new purchases via limited-company (SPV) structures. Section 24 finished its phased rollout in the 2020–21 tax year, leaving individual higher-rate landlords with only a 20% basic-rate tax credit on finance costs rather than full interest deductibility. For a £250,000 mortgage at 5.5%, that difference can be the margin between positive and negative after-tax cash flow.
The stamp-duty surcharge has also ratcheted up. The original 3% became 5% from 31 October 2024 under the Autumn Budget 2024 reforms. Combined with the April 2025 reset of first-time buyer thresholds (nil-rate to £300k, relief ceiling to £500k), the tax gap between an additional-property purchaser and a first-time buyer has never been wider.
The three big policy waves since 2018
1. Renters’ Rights Act 2024: the end of Section 21
The Renters’ Rights Act 2024 received Royal Assent and its main provisions took effect through 2025. The headline change was the abolition of Section 21 “no-fault” evictions, replaced by an expanded set of specified grounds under Section 8. Assured shorthold tenancies were converted to periodic tenancies, rent increases are now limited to once per year via a statutory notice, and a new Private Rented Sector Landlord Ombudsman handles complaints. For most landlords, the practical effect has been slower possession, more evidential burden on rent-arrears and antisocial-behaviour grounds, and a de facto extension of minimum tenancy length. It is survivable, but it is a meaningful shift in the balance of power.
2. EPC Minimum Energy Efficiency Standards (MEES)
The government’s 2025 policy statement confirmed that private-rental properties will need an EPC rating of C or above for new tenancies from 2028 and for all tenancies from 2030, replacing the current E minimum. Per the DESNZ impact assessment, the expected average upgrade cost per property where works are needed is around £6,800–£8,000, with a cost cap around £15,000 per property. For landlords of older London terraces and Victorian flats, the practical cost can easily exceed the cap, and the energy-performance uplift — cavity insulation, glazing, heat-pump readiness — is rarely recoverable in rent. This is a substantive capex headwind that the 2018 piece only briefly mentioned.
3. Capital gains tax on residential property
The April 2024 Finance Act cut the higher rate of CGT on residential property from 28% to 24% while leaving other asset classes on the reduced 20% and 10% bands. The annual exempt amount was also reduced to £3,000. The practical effect is that a landlord exiting a property with a £100,000 gain after the annual exemption pays roughly £24,000 in CGT — up from around £15,000 under the pre-2023 regime once allowance changes are factored in. The asymmetry with other investment classes remains punitive, and the exit friction is a real factor in why we are not seeing a forced, disorderly sell-off.
What the 2018 piece got right, wrong, and missed
Right: the core thesis that deliberate policy choices had fundamentally changed the buy-to-let economics for higher-rate UK taxpayers. Section 24 finished the job, the SDLT surcharge escalated, and the Renters’ Rights Act 2024 added the tenure-security dimension we suspected was coming. The prediction that individual landlord numbers would fall while rents would rise has also been broadly correct — ONS Private Rent Index data shows UK rents up roughly 30% between 2020 and 2025, well ahead of wage growth.
Wrong: the “collapse” implied by the original title didn’t come. The sector adapted. Limited-company (SPV) structures have absorbed much of the professional activity, wealthier landlords have consolidated rather than exited, and institutional build-to-rent has grown rapidly in major cities. The buy-to-let market did not die; it reshaped.
Missed: the scale of the SPV migration, the EPC upgrade requirements, and the policy importance of the Renters’ Rights Act framework. We also underweighted the counter-cyclical strength of rental yields once supply tightened — gross yields in many Northern and Midlands cities are now 7–9%, levels that made the arithmetic work for SPV-structured landlords even after all the tax changes.
The after-tax picture in April 2026
For a UK higher-rate taxpayer considering a marginal new buy-to-let purchase today, the key numbers look roughly like this:
- Additional-property SDLT surcharge: 5% on top of the standard band, so a £300,000 purchase incurs an SDLT bill of around £17,500.
- Buy-to-let mortgage rate: typically 5.50–6.00% for a 75% LTV five-year fix, with stress-tested Interest Coverage Ratio (ICR) requirements of 145% at 5.50%+ notional.
- Section 24 effect: mortgage interest no longer deductible against rental income; instead a 20% basic-rate tax credit applies, meaning the taxpayer owes 40% or 45% on gross rents less allowable expenses, with interest-only a deferred headache.
- CGT on exit: 24% on residential-property gains above the £3,000 annual exempt amount.
- EPC readiness capex risk: typically £5,000–£15,000 per property before the 2030 deadline where C-rating is not already achieved.
The after-tax yield net of all these costs, for a typical higher-rate individual landlord on a London or Southeast purchase at current rates, is frequently negative or barely positive in the early years. Capital appreciation is what has historically bailed out the strategy, and in London specifically, as we cover in the London housing piece, real-terms prices have actually declined about 15% since 2018. The numbers simply don’t work at the individual-name level for new London purchases.
Where the SPV route does still work
Limited-company BTL has continued to grow because the tax arithmetic is materially different. Inside an SPV: mortgage interest is a fully deductible business expense, profits are taxed at the prevailing corporation-tax rates (19%/25% depending on profit level) rather than 40%/45%, and retained earnings can be reinvested without being taxed as personal income. The trade-offs are additional accountancy and compliance costs (typically £1,500–£3,000 per year per SPV), limited-company BTL mortgage rates that tend to sit 25–50bps above personal BTL rates, and the 3.35% effective dividend-tax leakage when eventually taking profits out. For landlords with 3+ properties or higher leverage, the SPV route is now overwhelmingly the default; for one- or two-property landlords, the case is more finely balanced.
The cross-Channel alternative
The other development since 2018 has been the steady improvement of the French property market as an investment destination for UK higher-rate taxpayers. The combination of the LMNP (Loueur en Meublé Non Professionnel) furnished-rental regime — which still offers full depreciation-based tax shelter despite 2025 refinements — with typical French residential leverage at 3.0–3.5% on 20-year fixed terms and structurally lower property prices outside Paris means the after-tax yield on a well-chosen French purchase can exceed a UK equivalent even before factoring capital-gains treatment. Our France buying guide and SCI walkthrough are the practical starting points.
Frequently asked questions
Is buy-to-let still worth it in the UK in 2026?
For a UK higher-rate taxpayer buying a single additional property in their own name, the after-tax arithmetic is typically negative on a London or Southeast purchase at current mortgage rates, before factoring EPC upgrade costs. The strategy can still work via limited-company (SPV) structures, in higher-yielding Northern and Midlands markets, or for cash buyers. It rarely works on a leveraged individual-name London BTL.
What is the current stamp-duty surcharge on additional properties?
5% on top of the standard SDLT bands since 31 October 2024, up from 3% previously. On a £300,000 additional-property purchase, the SDLT bill is approximately £17,500, versus zero for a first-time buyer at the same price.
Has Section 21 really been abolished?
Yes. The Renters’ Rights Act 2024 abolished Section 21 no-fault evictions. Possession now requires specified Section 8 grounds (rent arrears, antisocial behaviour, landlord moving in or selling, etc.), with stricter evidential burdens and longer notice periods for most grounds. Existing assured shorthold tenancies converted to the new periodic regime during 2025.
When do the EPC C-rating rules bite?
The government’s confirmed policy is that all new tenancies will require an EPC rating of C or above from 2028, and all existing tenancies will need to meet C by 2030. Cost caps around £15,000 per property apply, but many older London flats will exceed the cap before reaching C.
Should I set up a limited company (SPV) for new buy-to-let purchases?
For most higher-rate taxpayers buying a third or subsequent property, yes. SPV structures restore full mortgage interest deductibility, tax profits at corporation-tax rates rather than 40%/45%, and allow retained earnings to be reinvested. The trade-offs are higher mortgage rates (25–50bps premium), additional compliance costs (£1,500–£3,000 per year), and dividend-tax leakage on eventual withdrawals. Existing personally-held portfolios are much harder to restructure because of SDLT and CGT on transfer.
Are UK landlords really leaving the market?
Net individual-landlord numbers are down, but the overall private rented sector is roughly flat in size because limited-company landlords have grown to offset the outflow. The sector has professionalised rather than contracted. Smaller, one- or two-property landlords are disproportionately leaving; larger, SPV-structured landlords continue to buy.
Bottom line
The 2018 piece was right about the direction of travel: policy was tilting decisively against the individual leveraged buy-to-let landlord, and that tilt has continued every year since. What we called “murder” was more precisely a forced professionalisation. The amateur, own-name, leveraged London buy-to-let landlord of the 2000s and 2010s is gone, or going. SPV-structured, professionally-managed, higher-yielding and often Northern buy-to-let is what remains. For many UK higher-rate taxpayers, the after-tax arithmetic now points either to corporation-tax-wrapped UK BTL in higher-yielding regions or to cross-Channel alternatives with materially better after-tax yields.
