With potential changes to Section 24 relief and EPC requirements, how will landlord profitability for HMOs be impacted in 2025-2026, and what specific strategies should I implement now to mitigate risks?
Quick Answer
HMO profitability will be challenged by Section 24 and EPC changes. Landlords should focus on energy efficiency and limited company structures to mitigate tax and compliance risks.
## How does Section 24 affect an HMO landlord's profitability?
Since April 2020, individual landlords, including those operating Houses in Multiple Occupation (HMOs), can no longer deduct mortgage interest from their rental income before calculating their tax liability. Instead, a tax credit equivalent to 20% of the finance costs is provided. This change primarily affects higher and additional rate taxpayers, as it effectively increases their taxable income and can push basic rate taxpayers into higher brackets.
For a landlord with £25,000 in rental income and £15,000 in mortgage interest, previously, their taxable income would be £10,000. Under Section 24, their taxable income is £25,000, and they receive a £3,000 tax credit (20% of £15,000). A higher rate taxpayer (40%) would have paid £4,000 tax (£10,000 x 40%) before Section 24. Now, they are taxed on £25,000 at 40% (£10,000) and receive a £3,000 credit, resulting in a net tax bill of £7,000. This represents a £3,000 reduction in profitability. This shift means that while the actual mortgage payment hasn't changed, the tax paid on the rental profit has increased significantly for many individual landlords, diminishing net rental yield.
## What are the upcoming EPC requirements for HMOs?
Current regulations stipulate that all rental properties, including HMOs, must meet a minimum Energy Performance Certificate (EPC) rating of E. However, future government proposals aim to raise this minimum standard to a C-equivalent for all new tenancies by 1 October 2025, and for all existing tenancies by 1 October 2030. There is a proposed cost cap of £10,000 per property for necessary energy efficiency improvements.
Meeting the EPC C-equivalent target for older, less efficient HMOs can involve substantial capital expenditure. Improvements could include upgrading insulation in walls, roofs, and floors, replacing single-glazed windows with double glazing, installing more efficient heating systems, or fitting solar panels. For instance, an HMO currently rated D might require £5,000-£8,000 in upgrades like cavity wall insulation and a new boiler to reach a C rating. A property rated F or G could easily exceed the £10,000 cap if extensive works are needed, such as external solid wall insulation, which alone can cost £8,000 for a typical terraced house, potentially leading to exemptions or the property becoming unlettable if the cap is reached without achieving C.
## How do these regulations specifically impact HMO landlord profitability?
The combined impact of Section 24 and upcoming EPC requirements can significantly erode HMO landlord profitability, particularly for individual investors. Section 24 directly reduces net rental income by increasing income tax liability for higher-rate taxpayers. An HMO generating £50,000 annual rental income with £30,000 in mortgage interest could see an additional tax burden of £6,000 for a 40% taxpayer compared to pre-2020 rules, directly affecting cash flow and return on investment.
EPC upgrades, on the other hand, represent a capital expenditure that might not directly increase rental income proportionally, but is mandatory to continue letting the property. Delaying these upgrades risks non-compliance, leading to potential fines of up to £5,000 per breach per property, or the inability to let the property, resulting in void periods and lost income. For an HMO with seven rooms, a void period of just two months due to non-compliance could mean £7,000-£10,000 in lost rental income, assuming average room rents of £500-£700.
## What are the key strategies to mitigate Section 24 risks?
To mitigate the impact of Section 24, landlords should consider several strategies. One primary approach is to operate the HMO property through a limited company. Corporation Tax is 25% for profits over £250k, 19% for profits under £50k, with marginal relief between these thresholds. Mortgage interest is a fully deductible expense for limited companies. This can significantly reduce the tax burden compared to individual ownership, especially for higher-rate taxpayers.
Another strategy involves increasing rental income or reducing other operational costs to offset the increased tax. Reviewing rents regularly to ensure they are at market rates, or exploring opportunities for value-added services in the HMO to justify higher rents, can help. For a landlord with £10,000 in additional tax due to Section 24, increasing overall monthly rental income by £84 per room across a 10-room HMO could effectively neutralise this impact, assuming current market conditions allow. For existing portfolios, refinancing to a lower interest rate, if possible, would also reduce the finance costs, indirectly lessening the Section 24 impact by reducing the base amount on which the 20% tax credit is calculated.
## What specific strategies should be implemented now to mitigate EPC risks?
Proactive planning for EPC improvements is essential. Landlords should obtain an up-to-date EPC for all their HMOs to identify current ratings and necessary upgrades. Consulting with an accredited energy assessor can provide a detailed roadmap for improvements, prioritising cost-effective measures first. For example, replacing older storage heaters with efficient electric heaters or an air source heat pump can improve EPC ratings significantly, alongside basic measures like loft insulation.
Phased implementation of upgrades is another effective strategy. Instead of waiting until the deadline, landlords can plan improvements during tenant changeovers or void periods to minimise disruption and lost rental income. Setting aside a dedicated capital expenditure fund for each property's EPC upgrades, for instance, £1,000-£2,000 per year over five years, can spread the financial burden and prevent a large, sudden outlay. An HMO needing to improve from an E to a C might require new windows (£3,000-£5,000) and improved loft insulation (£500-£1,000). Addressing these during a void period can save on tenant compensation or difficult access issues.
## What implications does corporate ownership have for HMOs?
Owning an HMO through a limited company offers distinct tax advantages, primarily regarding Section 24. A limited company can deduct 100% of mortgage interest from its rental income before Corporation Tax is applied. This means a company with £100,000 rental income and £60,000 mortgage interest would only pay Corporation Tax on £40,000 profit (at 19% or 25% depending on total profits), rather than the individual landlord scenario where tax is due on £100,000 of income with a 20% credit on the £60,000 interest.
However, corporate ownership introduces its own complexities. There are costs associated with setting up and maintaining a limited company, including annual accounts, company secretarial duties, and potential legal fees. Furthermore, extracting profits from a limited company is subject to further taxation, usually as dividends (tax-free up to £1,000, then 8.75% for basic rate, 33.75% for higher rate, 39.35% for additional rate). The initial transfer of properties from individual ownership to a limited company can also trigger Stamp Duty Land Tax (SDLT) and Capital Gains Tax (CGT). SDLT on residential properties attracts the 5% additional dwelling surcharge, meaning rates range from 5% on the first £125k up to 17% on values over £1.5M. CGT on residential property is 18% for basic rate taxpayers and 24% for higher/additional rate taxpayers, after the annual exempt amount of £3,000, which can be a substantial liability.
## Renovations That Add Value & Improve EPC
* **External Wall Insulation:** Reduces heat loss significantly, boosting EPC, and can refresh a property's exterior. Costs typically £8,000-£15,000 for a terraced house, potentially adding 1-2 EPC bands.
* **Modern, Efficient Boiler:** Upgrading from an old G-rated boiler to a new A-rated condensing boiler dramatically improves heating efficiency and EPC, and can be a strong selling point for tenants. Investment around £2,500-£4,000.
* **High-Performance Double/Triple Glazing:** Reduces heat loss through windows and noise, improving comfort and EPC. Costs vary by window type but expect £400-£800 per window.
* **Loft Insulation (270mm+):** One of the most cost-effective EPC improvements. Minimal disruption, significant impact on heat retention. Typically £500-£1,000 for an average loft.
* **Smart Thermostats & Controls:** Allows tenants to manage heating efficiently, contributing to lower energy bills and a better EPC score, while being an attractive modern feature. Cost often under £300.
## Common Pitfalls to Avoid
* **Ignoring EPC until the last minute:** Waiting for the 2030 deadline for existing tenancies can lead to a rushed, expensive, and potentially disruptive project, possibly during high-demand periods for trades.
* **Focusing solely on cosmetic upgrades:** While appealing, new kitchens and bathrooms rarely impact EPC ratings unless they include energy-efficient appliances or water-saving features. Prioritise fabric-first improvements for EPC.
* **Not checking local council policies:** Council tax premiums on second homes can be up to 100% from April 2025. Always confirm local policy, especially if you have temporary voids.
* **Overspending on EPC without a clear plan:** Without an energy assessment, you might implement costly measures that don't provide the most significant EPC uplift or are not covered by the £10,000 cost cap exemption.
* **Neglecting professional tax advice for company structures:** Setting up a limited company for property has specific tax and legal implications for transfer and profit extraction. Not understanding these can negate benefits.
## Investor Rule of Thumb
Proactive financial and energy efficiency planning is no longer optional; it is fundamental to maintaining profitability and compliance in the evolving UK property market.
## What This Means For You
Most landlords don't lose money because they ignore regulations; they lose money because they react too late or implement changes without a strategic understanding of the overall impact. If you want to know how these tax and energy efficiency changes specifically affect your HMO portfolio and how to build a robust mitigation strategy, this is exactly what we analyse inside Property Legacy Education. We help you move beyond awareness to actionable, profitable strategies.
Steven's Take
The shift in the regulatory landscape for HMOs, particularly around Section 24 and the upcoming EPC requirements, means that a 'business as usual' approach is no longer sustainable for individual landlords. I've built my portfolio by understanding and adapting to these changes. The critical thing here is to view these not as isolated problems, but as interconnected challenges requiring a holistic strategy. For Section 24, a limited company structure is often the most effective tax-efficient route for new acquisitions or if your personal income tax bracket makes it viable, but it's not a one-size-fits-all solution due to transfer costs. On the EPC front, start with an energy assessment on every property you own today. Understand what needs doing and budget for it. Don't wait for the October 2030 deadline. Integrating upgrades into your planned maintenance schedule or tenant changeovers makes financial and logistical sense, ensuring you stay compliant without massive, sudden capital outlays. These proactive steps are crucial for preserving your cash flow and protecting your investment's longevity.
What You Can Do Next
1. Obtain Professional Tax Advice: Consult a qualified property tax accountant to evaluate the impact of Section 24 on your specific financial situation and explore the viability of a limited company structure for your HMO portfolio. Resource: seek chartered accountants specialising in property, such as Property Tax Guys or Tax Natives.
2. Conduct EPC Assessments: Commission up-to-date Energy Performance Certificates for all your HMO properties to identify current ratings and detailed recommendations for improvements. Resource: find accredited energy assessors via the Government's EPC Register at find-energy-certificate.service.gov.uk.
3. Research Local Council Policies: Check your local authority's website for their specific policies on Council Tax premiums for second homes and empty properties to understand potential additional costs. Resource: visit your local council's official website (e.g., 'yourcouncil.gov.uk').
4. Create an EPC Upgrade Budget: Develop a phased capital expenditure plan for necessary EPC improvements, allocating funds over the next few years to avoid last-minute, costly rushed works. Resource: incorporate this into your existing property business plan or create a new dedicated budget sheet.
5. Review Current Mortgage Products: Evaluate your existing buy-to-let mortgage terms and rates. Consider if refinancing into a lower-rate product, where viable, could help mitigate some Section 24 impacts. Resource: consult an independent mortgage broker specialising in buy-to-let finance, such as Mortgages for Business or The Mortgage Works.
