Buy to Let UK 2026: Is It Still Worth It? Costs, Tax & Returns
Advertisement

Buy to let has become significantly more challenging since 2017. With the 5% stamp duty surcharge, Section 24 tax changes, higher mortgage rates and impending Section 21 abolition, careful analysis of returns is essential before investing. Updated April 2026

Buy to Let Stamp Duty — Added Cost in 2026

Purchase PriceStandard SDLTAdditional 5% SurchargeTotal SDLT (BTL)
£150,000£500£7,500£8,000
£200,000£1,500£10,000£11,500
£250,000£2,500£12,500£15,000
£300,000£5,000£15,000£20,000
£400,000£10,000£20,000£30,000
£500,000£15,000£25,000£40,000

The 5% additional property surcharge applies to all additional residential property purchases in England and Northern Ireland, including buy-to-let, second homes and holiday lets. This surcharge was increased from 3% to 5% in October 2024. Source: HMRC SDLT rates; multiple property investor guides verified April 2026.

Section 24 — The Tax That's Killing BTL Profit

Section 24 of the Finance Act 2015 (fully effective from 2020/21) restricts mortgage interest relief for landlords. Before Section 24: landlords could deduct mortgage interest from rental income, reducing taxable profit. After Section 24: only a 20% tax credit on mortgage interest applies, regardless of the landlord's tax rate. Impact on a higher-rate taxpayer with £10,000 rent and £6,000 mortgage interest:

Average Rental Yields by Region — 2026

RegionAverage Gross YieldKey CitiesAssessment
North East7-9%Newcastle, Sunderland, MiddlesbroughHigh yield; lower capital growth
North West6-8%Manchester, Liverpool, PrestonStrong yield + growth potential
Yorkshire6-7%Leeds, Sheffield, BradfordGood balance of yield and growth
East Midlands5-6%Nottingham, Leicester, DerbySolid yields; improving growth
West Midlands5-6%Birmingham, CoventryStrong growth + reasonable yield
Scotland5-7%Glasgow, Edinburgh (lower)Strong yields; ADS 8% adds cost
London3-4.5%All areasLowest yield; long-term capital growth
South East3.5-5%Varies widelyStretched affordability; modest yields

Gross yields — actual net returns significantly lower after mortgage costs, void periods, maintenance, management fees (8-12% of rent) and tax. Always calculate net yield for your specific situation.

Section 21 Abolition — What Landlords Must Know

The Renters' Rights Bill proposes to abolish Section 21 no-fault evictions from approximately May 2026 (subject to parliamentary progress — check gov.uk for current status). After abolition, landlords must use Section 8 grounds for eviction, which requires a specific legal ground (rent arrears, property damage, landlord wanting to sell or move in etc.). Key implications: eviction of difficult tenants will take longer and cost more; landlords should review tenancy agreements to ensure they are compliant; tenant referencing becomes even more critical.

KAELTRIPTON VERDICT
Buy to let in 2026 is viable in high-yield regions (North, Scotland) with the right purchase price and careful tax planning. It is significantly less attractive in London and the South East where net yields after mortgage costs and Section 24 tax can be near zero or negative. The 5% stamp duty surcharge, Section 24 restrictions and Section 21 abolition have collectively made BTL much harder work than before 2017. Serious landlords should model net returns carefully — not just gross yield.
High-Yield Regions Only — Model Net Returns
Q: Is buy to let worth it in 2026?
A: Viable in high-yield northern regions. Difficult in London and South East where net yields after mortgage costs and Section 24 tax can be minimal.
Q: What is the stamp duty surcharge for buy to let?
A: 5% additional surcharge on top of standard rates across all property value bands. Increased from 3% to 5% in October 2024.
Q: What is Section 24?
A: Restriction on mortgage interest deduction for landlords. Only a 20% tax credit now applies — significantly increases tax for higher-rate taxpayer landlords.
Q: When is Section 21 being abolished?
A: Section 21 no-fault evictions are being abolished under the Renters' Rights Bill — expected from approximately May 2026. Check gov.uk for current status.
