The way landlords manage property in 2026 is changing rapidly.
For years, many landlords relied on habits, processes, and management styles that worked perfectly well under the old rules. But with the Renters’ Rights Act 2026 coming into force on 1st May, some of the most common landlord mistakes from the past could now create serious legal and financial risks moving forward.
The challenge for landlords today is not necessarily that they have been doing things “wrong” — it’s that the rules have changed.
And the landlords who adapt early are likely to avoid problems later.
Here are some of the most common landlord mistakes we have seen over the years — and why landlords now need to rethink them under the new legislation.
1. Relying on Old Tenancy Agreements
For many years, landlords often reused old tenancy agreements without reviewing them regularly.
In the past, this may not have caused major issues. However, under the Renters’ Rights Act, tenancy agreements now need to reflect a very different rental system.
One important example is rent increases. Under the new rules, landlords should no longer rely on old-style rent review clauses in new tenancy agreements. Rent increases now need to follow the correct statutory process, such as the Section 13 route, rather than being built into the agreement through automatic review clauses.
Going forward:
Landlords should have their tenancy agreements properly reviewed and updated, not simply reused from previous years.
The focus should now be on ensuring the agreement reflects the new legal framework around:
- periodic tenancies
- possession grounds
- tenant notice requirements
- pet requests
- repair obligations
- access arrangements
- deposit protection
- compliance documents
- the correct legal process for future rent increases
This is not about slightly rewording old clauses. In some cases, landlords may need to remove outdated clauses entirely and replace old habits with the correct legal process.
A tenancy agreement that was acceptable under the old rules may now contain wording that is confusing, unenforceable, or misleading. That can create problems later if there is a dispute, a rent increase challenge, or a possession issue.
The safest approach is to make sure any new tenancy agreement is built around the post-May 2026 rules, rather than trying to patch up an old template.
2. Assuming Possession Was Straightforward
Under the previous system, many landlords became heavily reliant on Section 21 notices when they wanted possession of their property.
With the Renters’ Rights Act now changing the possession landscape, landlords can no longer assume regaining possession will be a straightforward administrative process.
Instead, possession is now far more dependent on landlords using the correct legal grounds, following proper procedures, and demonstrating that the tenancy has been managed correctly throughout.
What many landlords may discover is that issues arising at the end of a tenancy often begin much earlier through poor management practices, missing paperwork, or failure to deal with problems properly during the tenancy itself.
Going forward:
Landlords should focus on creating strong management systems from the very beginning of the tenancy.
This includes:
- carrying out regular inspections,
- responding to repair issues promptly,
- protecting deposits correctly,
- maintaining valid compliance certificates,
- documenting communication in writing,
- and keeping accurate records of tenant interactions.
Landlords should also become familiar with the updated possession grounds available under the new system and understand that evidence is likely to play a much greater role moving forward.
The days of relying on informal management and assuming possession will be simple later are likely to become increasingly risky.
3. Blanket “No Pets” Policies
Historically, many landlords automatically refused pets as standard practice to reduce concerns around damage, noise, or maintenance.
Under the Renters’ Rights Act, tenants now have stronger rights to request pets, and landlords may need to provide reasonable justification if refusing those requests.
This represents a significant shift away from the traditional “blanket ban” approach many landlords previously used.
Going forward:
Landlords should move away from automatic “no pets” policies and instead assess requests on a case-by-case basis.
That may involve considering:
- the type of property,
- the size or breed of the animal,
- lease restrictions where applicable,
- suitability of outdoor space,
- previous tenant references,
- and practical management considerations.
Landlords should also consider how they protect themselves properly through:
- detailed inventory reports,
- clear tenancy obligations,
- regular inspections,
- and suitable insurance arrangements where appropriate.
The key moving forward is demonstrating that decisions are reasonable, consistent, and properly considered rather than simply refusing requests automatically.
4. Informal Rent Increase Practices
Historically, some landlords handled rent increases informally through verbal conversations, text messages, or agreements made outside formal procedures.
Under the new legal framework, landlords can no longer rely on older informal methods.
For new tenancies created under the Renters’ Rights Act system, rent increases must now follow the correct statutory process rather than relying on contractual rent review clauses.
Going forward:
Landlords should ensure they fully understand the legal process surrounding rent increases before attempting to raise rent levels.
This includes understanding:
- when rent increases can legally take place,
- the notice periods required,
- the correct statutory procedure,
- and how tenants may challenge increases they believe are unreasonable.
Rent increases should also be supported by realistic local market evidence rather than simply reacting to inflation or rising costs.
Poorly handled increases could increase the likelihood of disputes, tribunal referrals, or longer-term tenant instability.
Moving forward, landlords are likely to benefit from approaching rent reviews strategically and professionally rather than informally.
5. Leaving Compliance Until the Last Minute
For years, many landlords treated compliance as something to deal with when reminders arrived or just before documents expired.
However, under the increasingly regulated rental landscape, compliance is becoming much more closely connected to wider tenancy management and landlord liability.
What may previously have been seen as a minor oversight could now create much larger legal or financial consequences.
Going forward:
Landlords should move towards a far more proactive approach to compliance management.
That includes staying on top of:
- Gas Safety Certificates,
- EICR inspections,
- EPC requirements,
- smoke and carbon monoxide alarm regulations,
- repair obligations,
- damp and mould prevention,
- and property condition standards.
Councils and tenants are placing increasing scrutiny on property conditions, particularly around health and safety concerns.
Landlords should also ensure documents are:
- renewed on time,
- properly served where required,
- and stored securely in case evidence is needed later.
Strong compliance systems are likely to become one of the most important foundations of successful property management under the new legislation.
6. Poor Record Keeping
Historically, many landlords relied heavily on phone calls, informal conversations, or verbal agreements with tenants.
The problem is that when disputes arise, verbal discussions can be difficult to evidence later.
As the private rented sector becomes increasingly regulated, written records are becoming more important than ever.
Going forward:
Landlords should ensure they maintain organised records covering:
- inspections,
- maintenance issues,
- repair requests,
- contractor works,
- notices served,
- rent discussions,
- tenant complaints,
- and communication history.
Simple habits such as confirming conversations by email, keeping photographic evidence from inspections, and logging maintenance timelines can make a major difference if disputes occur later.
Even where landlords believe they have acted reasonably, demonstrating that actions were taken correctly — and at the right time — may become increasingly important under the newer legal framework.
Good documentation protects not only the landlord, but often helps prevent disputes escalating unnecessarily in the first place.
7. Underestimating How Fast the Law Is Changing
Perhaps one of the biggest mistakes landlords have made historically is assuming the rental market changes slowly.
In reality, the private rented sector has seen continuous legal reform over recent years, with the Renters’ Rights Act representing one of the most significant shifts landlords have faced in decades.
Many landlords are still operating using habits, assumptions, or advice based on a system that no longer fully exists.
Going forward:
Landlords should avoid relying solely on outdated online advice, old tenancy templates, or assumptions based on how the market operated previously.
Instead, landlords should regularly review:
- tenancy agreements,
- compliance systems,
- possession procedures,
- communication practices,
- and rent management processes.
The landlords most likely to succeed over the next few years are likely to be those who adapt early rather than waiting until problems arise.
Managing rental property is increasingly becoming about managing risk, compliance, and process — not simply collecting rent each month.
Final Thoughts
The Renters’ Rights Act 2026 is still very new, and many landlords are only beginning to understand how significantly the private rented sector is changing.
Most landlords have not intentionally managed property incorrectly over the years. In many cases, they were simply following systems and habits that worked under the old rules.
But the reality is that being a landlord in 2026 is becoming far more complex.
Managing property today is no longer just about collecting rent and arranging repairs. Landlords are now expected to understand:
- changing legislation,
- compliance obligations,
- possession procedures,
- tenant rights,
- documentation requirements,
- and increasingly detailed management processes.
For some landlords, especially those with full-time jobs or multiple properties, keeping on top of these responsibilities is becoming increasingly difficult.
This is one reason why many landlords are now reconsidering whether self-management is still the best option moving forward.
A good managing agent should not simply collect rent — they should help landlords reduce risk, stay compliant, keep accurate records, manage tenant communication professionally, and adapt to changing legislation before problems arise.
As the rental market continues evolving, professional management may become less of a convenience and more of a form of protection for landlords trying to navigate an increasingly regulated sector.
