On 27 October 2025, the UK government passed the Renters' Rights Act into law.
Whether you're a first-time buyer from overseas or an experienced investor, you need to know about it because it is reshaping how lenders view rental income and possession risk. Brokers we speak to say this often shows up as slower approvals and more questions, and overseas buyers tend to feel it first.
This article explains what the Renters' Rights Act does, why lenders are responding the way they are, and what that means for your next property purchase or refinance.

What is the Renters' Rights Act?
The Renters' Rights Act is the most significant change to renting in the UK in more than 30 years. It affects how landlords and tenants interact in the private rental market.
The core idea is simple. Tenants get more security. Landlords get more rules to follow.
For you, as an overseas investor, the Renters’ Rights Act does not stop you from buying UK buy-to-let property, nor does it bar you from getting a mortgage either.
What it changes is the risk and documentation lenders look at. The Act itself sets tenancy rules; the tighter underwriting around landlord compliance, cash flow, and portfolio strategy is how lenders are choosing to respond to it.
What are the key Renters’ Rights Act changes?
Most main rules took effect on 1 May 2026. Other rules will be introduced gradually through 2027 and beyond.
Here is what has changed so far and what is still on the way:
Here is what the new tenancy changes mean in plain terms:
1. Rent in advance is restricted
Before 1 May 2026, some landlords asked tenants for six or twelve months’ rent upfront. That is no longer allowed. Now, you can only collect one month’s rent before a tenancy begins.
2. Rent increases follow a strict process
You can still raise the rent to the market rate, but only once every 12 months. You must give at least 2 months’ written notice using a formal Section 13 notice.
Tenants can challenge the increase at the First-Tier Tribunal, which is an independent UK body that handles specialised legal disputes. The rent stays at the old rate until the tribunal makes a decision.
The limit is on how often and how you raise the rent, not a cap on the amount: the tribunal decides what the market rent is, and you can still move to that level.
3. No more fixed-term tenancies
Every tenancy is now open-ended. You cannot ask a tenant to leave without a legal reason. Instead, you must use one of the "grounds for possession" in Section 8, like selling the property or moving in yourself. In most cases, you will need a court order.
Market sentiment: is UK buy-to-let still worth it?
Big changes like these can make investors, especially those from overseas, feel nervous. It is normal to have questions before you invest from abroad.
The data so far does not point to a landlord exodus. Rental yields across England have remained resilient. Gross yields are commonly reported in the 5.8% to 7.2% range nationally, according to recent market data by BuyAssociation Group. Tenant demand remains high, driven by a persistent shortage of rental homes.
Most mortgage brokers who work with overseas landlords believe the Renters' Rights Act does not threaten buy-to-let as an investment. It encourages the market to become more professional and better documented, moving away from casual or one-off landlords.
Still, overseas investors who act quickly and follow the rules often benefit the most.
What does the Renters' Rights Act mean for overseas investors?
The Renters' Rights Act affects everything from how a lender looks at your deal to how you manage a tenancy as a landlord.
For overseas investors, the biggest impact is on financing, so we will focus on that here. It helps to think of these changes as a chain, not just a single change:
- The Act raises the compliance burden on landlords.
- The burden increases the risk lenders perceive if a tenancy goes wrong.
- Lenders respond by tightening the checks they conduct on rent, management, and exit assumptions.
Overseas investors feel this the most, since cross-border files already take longer to verify, even before adding extra checks.
It is worth being clear about one thing: none of these lender checks are written into the Renters' Rights Act. They are how lenders, valuers, and brokers are responding to the new risk picture.
Much of the extra friction, the slower approvals, the more cautious valuations, the added paperwork, comes from lender policy and cross-border verification, not from a mortgage rule in the Act itself.
With that in mind, here is what brokers are reporting in practice:
Rental income assumptions get tighter
Lenders check if your rental income covers your mortgage payments with a safe margin, using something called the Interest Coverage Ratio (ICR). Most lenders want rental income to be 125% to 145% of a stressed monthly payment, not just the current payment.
Two changes are leading some lenders to push that stress test in a more cautious direction:
- Rent increases are now limited to once a year and can be challenged. A Section 13 notice, which can only be used once a year, replaces rent review clauses. Tenants can contest this at a tribunal, so some lenders are taking a more cautious view of future rent growth.
- Rent in advance is now restricted. Investors can no longer rely on collecting several months of rent upfront to help with affordability at completion. In practice, that may mean a bigger deposit or a guarantor to provide the same buffer.
Lenders are checking your compliance record, not just your finances
Two new organisations are changing how lenders check your application. The Private Rented Sector Database will require you to register both the property and yourself as the landlord before you can market it to let. If you are not registered, you cannot serve valid possession notices on most grounds.
A separate Private Rented Sector Ombudsman scheme is also becoming mandatory, and its decisions can be enforced like a court order.
In practice, many lenders are likely to ask for proof of registration well before the Ombudsman deadline. If a property is not registered correctly, it is not just a compliance issue. It is a real risk to a lender's ability to enforce their security if something goes wrong, so do not treat registration as paperwork you can put off.
Valuations are getting more conservative
In practice, property valuers are taking a more cautious view of rental income and possession assumptions under the new Act, especially in areas with lower yields. If you already own a property in England and a revaluation is coming up, do not assume the value will be the same as before.
This does not mean UK mortgages are out of reach for overseas buyers. It just means lenders want a stronger, more cautious application which includes:
- Realistic rent numbers
- A clear letting and management plan
- Big enough deposit for a careful valuation

What should overseas investors do?
- Register early. Once the Private Rented Sector Database opens, register the property and yourself before marketing it. Missing registration can block a possession claim and is now a lender question too.
- Build your case before you apply. Have a documented management plan ready, ideally with a UK-based letting agent.
- Rework rent-in-advance arrangements. If you relied on several months upfront, that route is being closed off. Talk to your broker about a guarantor or larger deposit instead.
- Expect slower underwriting and plan for it in your completion timeline.
- Test your own numbers using a lower rent and a more conservative loan-to-value before the lender does.
- Keep your deposit protected with a backup plan if your mortgage is delayed.
This is where timing becomes the real risk, not the law itself. A mortgage approval is not helpful if it comes after your completion deadline.
Bridging finance can help if timing is tight and you need to complete a purchase before your long-term mortgage is ready. A bridging loan is a short-term loan that lets you finish the purchase on time while your main mortgage is still being processed.
It gives you room to protect your deposit while a standard mortgage goes through the extra checks lenders now require.
Note: Bridging loans can help you protect your deposit while your standard mortgage is being processed and lenders carry out extra checks. However, bridging is not always the right solution. It only makes sense if you have a clear exit strategy, such as your mortgage being approved or a sale going through, and if the loan costs still fit your budget.
Conclusion
To sum up, the Renters' Rights Act does not stop overseas investment in UK property. It changes how lenders assess the risk of lending against a tenancy, which means you need to be more prepared before you apply.
The main risk is timing. It now takes longer to regain possession, and lenders are more cautious. If your mortgage is delayed at the wrong time, you need a plan that does not depend on the bank moving quickly.

Key takeaways
- The Renters' Rights Act 2025 received Royal Assent on 27 October 2025. Most major changes took effect on 1 May 2026.
- Section 21 "no-fault" evictions are abolished. All possession now requires a legal ground and, in most cases, a court order.
- Rent can only rise once every 12 months, with two months' written notice through a Section 13 process. This limits how often you raise rent, not the amount, which can still reach market rate.
- Rent in advance is being restricted, widely understood as roughly one month before a tenancy starts, removing a tool some overseas landlords previously relied on. The exact rules and start date are still to be confirmed.
- Mortgage lenders, not the Act itself, are applying tighter scrutiny to buy-to-let applications, including from overseas investors, as a response to the new risk picture.
- Bridging finance can keep a purchase on track if a mortgage is delayed under the new rules, provided the exit is realistic and the cost works.
Frequently asked questions
Can I still get a UK mortgage as an overseas landlord after the Renters' Rights Act?
Yes, lenders still approve overseas applications. Expect closer checks on rental income, your management plan, and the property's condition.
Does the Renters’ Rights Act stop me from evicting a tenant who stops paying rent?
Yes. You can still evict for rent arrears, but you now need a Section 8 ground and usually a court application, which takes longer.
How much rent in advance can I ask for now?
The Act limits large upfront payments, which most people take to mean about one month’s rent before a tenancy starts, although the government is still finalizing the details. If you used to ask for several months in advance, using a guarantor is now the practical option.
What happens to a tenancy that started before 1 May 2026?
It converted automatically to an assured periodic tenancy. No new agreement needed, but old fixed-term or rent-review clauses no longer apply.
Will a bridging loan help if my mortgage is delayed under the new rules?
Yes, a bridging loan can help you buy a property while your mortgage is being processed, so your deposit is safe within the seller's timeframe. This option works best if your mortgage or sale is likely to go through and the costs make sense for your situation.
