What Does the Renters’ Rights Act Mean for Buy to Let Investors?

Your tenant pays on time, the mortgage is covered, and your property is rarely empty. Then the rules change. Does that mean your investment no longer works, or simply that the way you manage it needs to change?

The Renters’ Rights Act is prompting landlords to reassess their buy to let plans, from tenancy procedures to borrowing and whether each property still earns its place in the portfolio.

The answer starts with understanding the changes and testing your figures. This guide covers private rented housing in England. Different rules operate elsewhere in the UK.

What Is the Renters’ Rights Act and What Has Changed?

The Renters’ Rights Act 2025 reforms private renting, with its main tenancy changes taking effect on 1 May 2026. Under the new tenancy system, most existing assured shorthold tenancies became assured periodic tenancies, which run without a fixed end date.

The main changes include:

• No new Section 21 “no-fault” eviction notices. Landlords need a valid legal ground to seek possession

• Tenants can generally leave with two months’ notice, although shorter periods can apply

• Rent increases are limited to once annually through the statutory process.

• Rental bidding above the advertised rent is prohibited

• Restrictions apply to rent in advance, including a one-month limit between signing and the tenancy starting

• Landlords must consider pet requests and cannot unreasonably refuse them

• Discrimination against applicants because they receive benefits or have children is prohibited

These are the core changes for private landlords, rather than an exhaustive compliance checklist.

How Will the Changes Affect You as a Landlord?

Managing an ongoing tenancy requires clear procedures. Keep accurate records of payments, repairs, inspections and communications. If problems arise, the grounds for possession you rely on, the notice and the supporting evidence matter. Serving notice does not itself remove a tenant; court proceedings may be necessary if they remain.

Ask your letting agent how they have updated agreements, advertising and rent reviews. Good communication and prompt repairs can also help retain tenants and reduce avoidable disputes.

What Could the Renters’ Rights Act Mean for Your Rental Income?

The Act changes how you plan and increase rental income, rather than automatically reducing it.

For affected tenancies, landlords must use the section 13 process and Form 4A, giving at least two months’ notice of an increase. Rent cannot normally increase during the first year of a new tenancy or more than once a year thereafter. Tenants can challenge a proposed increase at a tribunal if they believe it exceeds the open-market rent. Existing rent-review clauses cannot replace the statutory process. See the government’s rent-increase guidance.

Do not assume rising landlord costs can always be passed straight to tenants. Budget for vacancies, arrears and reletting expenses, rather than treating twelve months of uninterrupted rent as guaranteed.

Consider an illustrative property receiving £1,200 monthly, with £750 in mortgage payments and £250 allocated to other running costs and reserves. That leaves £200 before tax. A £1,200 repair beyond those allowances would absorb six months of that surplus. Your own figures may differ, however, this shows why cash reserves matter.

Should You Review Your Buy to Let Mortgage?

Reviewing your mortgage may not mean replacing it. Check your rate, deal expiry date, payments and early repayment charges.

Buy to let refinancing could offer different terms or funds for improvements. However, fees and a higher replacement rate could outweigh the benefits. If your mortgage is on a repayment basis, extending the term may reduce monthly payments but increase the total interest paid. Extending an interest-only term does not repay the outstanding capital.

Lenders assess rental coverage, property value and potentially your finances and wider portfolio. Do not rely on an unconfirmed rent increase to support borrowing. At Crystal Property Finance, we can help you explore your options.

Is Your Property Still a Good Investment?

If you are asking, “Is now a good time to buy a house?”, start with your own finances rather than the national market. A few practical questions can help:

• Do you have a sufficient deposit without using all your savings?

• Can you cover legal fees, surveys, removals and any applicable property purchase tax?

• Would the monthly mortgage remain affordable alongside bills and other commitments?

• Do you have a stable income and money available for unexpected expenses?

• Are you likely to stay in the property long enough for buying to suit your plans?

• Would you still be comfortable if your payments increased when an initial mortgage deal ended?

Mortgage affordability is not simply a multiple of your salary. Lenders may assess your income, expenditure, debts, dependents, deposit, credit history and proposed term.

They may also test whether the loan would remain affordable if borrowing costs increased.

This is why “How much can I borrow for a mortgage?” and “How much should I borrow?” are different questions. A lender’s maximum may be higher than the amount that feels comfortable once you include council tax, energy, insurance, maintenance and other priorities.

If buying would use all your emergency savings or stretch your budget every month, waiting may be sensible. If you have a suitable deposit, a resilient budget and a property that fits your longer-term needs, uncertainty about next year does not automatically mean you should delay.

Is Your Property Still a Good Investment?

A buy to let property investment should be judged on returns after costs, not advertised rent.

Calculate annual cash flow after mortgage payments, management fees, insurance, repairs, service charges where applicable and realistic vacancy allowances. Consider tax separately with an accountant. Then ask:

• Does local tenant demand support your expected rent?

• Can the property absorb a major repair or several months without rent?

• Are improvements needed, and what would they cost?

• Does the likely return justify your time, risk and equity tied up?

When reviewing buy to let investment in 2026, distinguish the Act’s effects from existing borrowing, tax and maintenance pressures.

Should You Keep, Sell or Expand Your Property Portfolio?

Keeping may suit a property with reliable demand and sustainable cash flow. Selling may warrant consideration where returns remain weak or major work no longer fits your plans. Expansion needs its own appraisal, not an assumption that another property will offset existing problems.

Selling does not automatically end a tenancy. You may be able to sell with tenants in place. If seeking possession to sell, the relevant ground generally requires at least four months’ notice, which cannot expire before the first twelve months of a new tenancy has ended. Conditions and restrictions on subsequent reletting also apply, so obtain legal advice before serving notice or promising vacant possession.

Review each property individually before making a decision about your whole buy to let portfolio. Include selling costs, mortgage exit charges and potential tax liabilities.

How Can You Prepare for the Changes?

By September 2026, the main tenancy reforms are already in force. Preparation now means checking compliance and planning for later phases.

Check that required tenancy information has been supplied. For most existing written tenancies, the government Information Sheet was due by 31 May 2026. If anything was missed, seek advice promptly. Review safety records, deposit protection, licensing and maintenance budgets too.

The government plans to roll out rental-property registration regionally from 15 December 2026, beginning in the West Midlands. The landlord ombudsman and further property-standard reforms will follow separately. Check the applicable dates rather than assuming every measure is already operational.

It is important to note additional borrowing increases your commitments, and improvements do not guarantee higher rent or value. Obtain separate legal and tax advice where needed.

What Should Buy to Let Investors Do Next?

Start with one property and three questions: are the tenancy arrangements compliant, does the cash flow work, and does the mortgage still suit your plans?

The Renters’ Rights Act is a reason to review your approach, not an automatic instruction to sell or borrow more. Understanding your obligations and testing your numbers will give you a firmer basis for deciding what comes next.
