If you're a UK landlord, the next few years are shaping up to be some of the most significant we've seen in decades. From higher tax rates and Making Tax Digital changes to the new landlord database and evolving mortgage market conditions, there is a lot to keep track of.
The challenge is that these announcements often arrive separately, making it difficult to see the bigger picture. As mortgage brokers working with landlords every day, we believe the real value lies in understanding how these changes fit together and what practical steps you can take now.
Here's our overview of the key developments affecting buy-to-let landlords and property investors over the coming years.
Higher Tax Rates for Individual Landlords
The headline announcement from the Autumn Statement was a significant increase in tax on rental profits for landlords who own property in their personal names.
From April 2027, rental profit tax rates are set to increase to:
- 24% for basic-rate taxpayers
- 44% for higher-rate taxpayers
- 49% for additional-rate taxpayers
For many landlords, this will represent a substantial increase in tax liabilities and could further reduce net rental profits.
While details around mortgage interest relief under Section 24 are still awaiting legislative confirmation, current expectations are that the associated tax credit will also increase. However, higher-rate taxpayers are still likely to face a similar gap between their tax rate and the available relief.
Importantly, landlords with lower borrowing levels may feel the impact more than expected. Because the increased tax is ultimately applied to profit, those generating stronger net rental income could see some of the largest increases in their tax bills.
Will More Landlords Consider Incorporation?
One notable exception is limited company landlords.
Properties held within a limited company structure remain subject to corporation tax rather than the new personal rental income tax rates. For many investors, this may prompt a fresh review of whether incorporation could be appropriate.
Incorporation is not suitable for everyone and tax advice should always be sought before making any changes. However, landlords who previously ruled it out may find that the calculations look very different once the new tax rates arrive.
Reviewing Ownership Structures
For landlords who own property with a partner or spouse, it may also be worth reviewing how ownership is arranged.
Where ownership is structured as tenants in common, rental income can potentially be allocated according to beneficial ownership percentages. In some circumstances, adjusting ownership shares could help make better use of lower tax bands within a household.
As always, specialist tax advice is essential before making any decisions, but it highlights how important tax planning is becoming for property investors.
Bank of England Base Rate Expectations
The mortgage market remains closely tied to expectations around the Bank of England base rate.
Current market pricing suggests a strong possibility of further base rate increases, with expectations that rates could remain elevated throughout much of 2027 before easing.
For landlords approaching a remortgage or product transfer, the key message is simple: uncertainty remains.
While swap rates have been relatively stable recently, there has not yet been a meaningful improvement in pricing. Mortgage rates have therefore remained broadly unchanged, with lenders continuing to price cautiously.
Fixed Rate or Tracker?
Many landlords are currently weighing up whether to choose a fixed-rate mortgage or a tracker product.
Two-year fixed rates are proving particularly popular among landlords who want flexibility and hope that rates may ease in the medium term.
Trackers can also be attractive, but they carry additional risk if base rate increases continue. Before opting for a tracker, landlords should carefully consider how future rate rises could affect affordability and cash flow.
Seeking advice early, ideally six months before a mortgage expires, can provide more options and reduce unnecessary pressure when a deal ends.
The New Landlord Database Is Approaching
One of the biggest regulatory developments on the horizon is the new landlord registration system.
The Register Your Rental Property service starts rolling out from December 2026, with regions joining in phases before national implementation.
Landlords will need to register rental properties, provide key information and upload compliance documentation such as:
- Gas safety certificates
- Electrical safety certificates
- EPCs
- Ownership details
- Managing agent information where applicable
Registration fees are expected to be £65 per property per year.
Why Are Landlords Concerned?
One of the biggest areas of uncertainty is exactly what information will become publicly accessible.
While the Government has indicated that not all landlord data will be publicly available, the final rules regarding publication and data sharing have not yet been confirmed.
Many landlords have expressed concerns around privacy, identity theft and data security. Further guidance is expected before the nationwide rollout continues.
For now, the best approach is to ensure your documentation is organised and ready well before registration becomes mandatory.
Energy Bill Liability Proposal
A separate proposal currently under discussion could potentially create new responsibilities for landlords.
The proposal would require landlords to notify energy suppliers when tenants move in or out of a property. Where neither landlords nor tenants provide the necessary information, landlords could potentially become liable for outstanding energy charges.
This is not yet law and would require further legislation before implementation.
However, it highlights the increasing importance of robust tenant onboarding and check-out processes. Keeping accurate records and ensuring suppliers are informed promptly could become an important compliance requirement in the future.
Making Tax Digital Expansion
Making Tax Digital (MTD) continues to move closer for many landlords.
Currently, landlords and self-employed individuals with qualifying income above £50,000 must comply with MTD requirements.
The thresholds are due to fall further:
- £30,000 from April 2027
- £20,000 from April 2028
Importantly, eligibility is based on gross income rather than profit.
Many landlords who currently assume MTD will not affect them may find themselves within scope sooner than expected. Reviewing income levels and researching suitable software now could prevent problems later.
EPC Changes Remain on the Horizon
Although not yet law, proposed EPC requirements remain a major consideration for landlords.
Current plans indicate that privately rented properties may need to achieve a minimum EPC rating of C by 2030, subject to consultation outcomes and final legislation.
With a proposed cost cap of £10,000 before exemptions can be claimed, landlords with older properties should begin assessing potential upgrade requirements well in advance.
Energy efficiency improvements often take time to plan and budget for, particularly across larger portfolios.
What Should Landlords Be Doing Now?
With multiple changes approaching at once, preparation is becoming increasingly important.
We recommend that landlords:
- Review mortgage expiry dates at least six months in advance.
- Obtain up-to-date property valuations.
- Check current and achievable market rents.
- Consider seeking tax advice before April 2027.
- Review ownership structures where appropriate.
- Prepare documentation for landlord registration requirements.
- Assess EPC ratings and future upgrade costs.
- Familiarise themselves with Making Tax Digital requirements.
Final Thoughts
The next few years look set to bring significant change for UK landlords. Higher taxes, increased regulation, ongoing mortgage market uncertainty and stricter compliance requirements will all require careful planning.
The good news is that landlords who prepare early typically have more options available to them, whether that's restructuring ownership, reviewing borrowing arrangements, improving property efficiency or simply putting robust systems in place before new rules arrive.
If you're reviewing your buy-to-let portfolio, approaching a mortgage renewal or considering incorporation, speaking to an experienced landlord mortgage broker can help you understand how these changes may affect your borrowing options and long-term investment strategy.
